Description

  The present invention receives a broadcast signal (particularly a digital broadcast signal) including event information and content data related to an event (program) broadcast on a plurality of services (channels), and video and / or audio corresponding to the received content data. A broadcast receiver capable of displaying a plurality of electronic program guides for each broadcast presentation unit based on the received event information, and a display method, program, and recording medium for the electronic program guide in the broadcast receiver Is.

  In recent years, in television broadcasting, digitization has been promoted in terrestrial broadcasting as well as CS (communication satellite) broadcasting and BS (broadcast satellite) broadcasting. In multiple types of digital broadcasting such as CS digital broadcasting, BS digital broadcasting, terrestrial digital television broadcasting, etc., together with video information and audio information (content data) constituting the broadcasting event itself, for example, event name, event broadcasting date and time, SI (Service Information) including multiplexing of event information (information related to the broadcast event) such as event contents and event performers is also included in the digital broadcast signal and transmitted.

  A broadcast receiving apparatus that receives a digital broadcast signal including SI as described above uses an electronic program guide (hereinafter referred to as “EPG”) as an interface that is easy for a viewer to select an event using the SI. And display it on the screen. As a method of using the EPG, for example, a method is known in which a user selects a desired event on the EPG screen and displays a selected event or schedules recording of the selected event.

  Furthermore, the received event information is received while receiving a digital broadcast signal broadcast by CS digital broadcast, BS digital broadcast, and terrestrial digital television broadcast, and outputting video and / or audio corresponding to the received digital broadcast signal. The first network of CS digital broadcasting (hereinafter referred to as “CS1 network” or “CS1”), the second network of CS digital broadcasting (hereinafter referred to as “CS2 network” or “CS2”), BS digital broadcasting And a digital broadcast receiver capable of switching and displaying EPGs related to terrestrial digital television broadcasts.

  For example, in the liquid crystal television “AQUIS G series” (for example, “LC-37GD3” and “LC-37GD4” released on September 1, 2004) sold by the applicant at the time of filing this application, CS digital broadcasting and BS digital broadcasting , And a function of receiving a digital broadcast signal broadcast by terrestrial digital television broadcast, and an EPG can be superimposed and displayed on a video corresponding to the received digital broadcast signal, and the CS1 network, The EPG relating to the four broadcast presentation units of the CS2 network, the BS digital broadcast, and the terrestrial digital television broadcast can be switched with each other.

  Further, in Patent Document 1, in order to solve the problem that “it is impossible to refer to program information in another network while viewing a program (event)”, the program information is transmitted from the transmitted stream. A receiver that extracts simplified information from the program information and extracts simplified program information to form simplified program information and provides an electronic program guide function based on the program information and the simplified program information Is described.

  According to the above configuration, even in a situation where program information cannot be acquired, the function of an electronic program guide can be provided by referring to already stored program information or simplified program information. It is also possible to refer to information that cannot be obtained without receiving a specific stream, while selecting the channel being viewed. Therefore, regardless of which satellite or stream is being received, the minimum simplified program information for constructing the program guide etc. is stored in the storage means of the terminal, so that the user selects The program guide can be presented while the channel is selected.

  Moreover, according to the said structure, since the simplified program information exists also about the network which has not received, a program schedule can be shown incompletely. And when the user calls the function of the electronic program guide using the program information, the program information acquired in advance is used to receive information other than the receiving network without switching the receiving network. It becomes possible to refer to the same information as the network information.

Furthermore, in the broadcast receiving apparatus of Patent Document 1, the user views / reserves a program displayed by the simplified program information or acquires detailed information in a state where the program guide is presented incompletely for a network that has not been received. When selected for the purpose, a network and a stream that transmit necessary program information are selected.
JP 2001-211400 A (published on August 3, 2001; paragraphs [0092] to [0100], etc.)

  However, in the above-mentioned liquid crystal television “AQUIS G series”, the user is instructed to display another broadcast presentation unit EPG while the broadcast presentation unit EPG to which the service broadcasting the currently viewed broadcast event belongs is displayed. Is input, the EPG of other broadcast presentation units is displayed, and one service (for example, promotion channel) of other broadcast presentation units is selected (tuned) to acquire event information of other broadcast presentation units. Is supposed to do. As described above, since the conventional broadcast receiving apparatus performs an operation of selecting a service of another broadcast presentation unit, when displaying an EPG of another broadcast presentation unit, the EPG of another broadcast presentation unit is displayed. The video and audio of the event that was being watched until immediately before disappearing (the screen turns black and the sound is muted). In particular, even when the user wants to browse an EPG of another broadcast network for only a short time, the video or audio of the event being viewed is interrupted. Therefore, it was not easy to use.

  In addition, in the configuration of Patent Document 1, when only an incomplete program representation can be obtained, an operation for viewing detailed information of a program or an operation for performing viewing / reservation processing of a program is performed. Necessary program information is acquired by switching the program. Note that the detailed information of the program is more detailed information than the program information such as the program name displayed first on the EPG, for example, whether it is a genre, dual sound, stereo sound, etc. Information. In addition, although an operation for viewing detailed information of a program and an operation for performing viewing / reservation processing of a program vary depending on the specifications of the digital broadcast receiving apparatus, typically, a remote controller ( Hereinafter, an operation of selecting a program using “remote control” and pressing a predetermined key.

  However, in the configuration of Patent Document 1, when only an incomplete program representation can be obtained, the user can perform an operation for viewing detailed information of a program, or viewing / listening of a program in order to obtain necessary program information. An operation for performing reservation processing must be performed.

  The operations for viewing the detailed information of the program and the operations for viewing / reserving the program are performed by the user simply browsing the program guide (viewing the detailed information of the program, performing the viewing / reserving process of the program, etc.) Do not do this sometimes. Therefore, if the user does not know the operation method, the user cannot intuitively understand what operation should be performed in order to acquire necessary program information. Therefore, the user cannot obtain necessary program information unless he / she sees an instruction manual or the like. That is, when there is a missing program in the program guide, the user thinks that the missing part will be added if any operation is performed, and various keys normally used for browsing the normal program guide. Even if the operation is performed, the program information of the missing part cannot be acquired. Therefore, even if the operation method is written in the instruction manual or the like, a beginner who does not understand well will be confused.

  Further, in the configuration of Patent Document 1, when an operation for acquiring necessary program information is performed, a state in which detailed information on a program is displayed from a state in which a normal program guide is displayed, a program viewing / reservation It will shift to the state which is displaying the display screen for processing. Therefore, necessary program information cannot be acquired while maintaining a state where a normal program guide is displayed.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to belong to a service that broadcasts the event while continuing to view and / or listen to the audio of the event. Broadcast receiving apparatus and electronic program guide display method, program, and recording capable of browsing EPG related to broadcast presentation unit different from broadcast presentation unit and updating EPG by user's intuitive operation To provide a medium.

  In order to solve the above problems, the broadcast receiving apparatus of the present invention includes a plurality of event information and content data related to events broadcast by a plurality of services belonging to a plurality of broadcast presentation units having different event information distribution methods. Based on the event information stored in the storage unit, the reception unit that receives the broadcast signal while switching, the storage unit that stores the event information received by the reception unit, and the plurality of services belonging to each broadcast presentation unit An electronic program guide creation unit created while switching a plurality of electronic program guides for each broadcast presentation unit showing a list of events broadcast in each, and displaying the electronic program guide created by the electronic program guide creation unit, An output unit for outputting video and / or audio corresponding to the received content data. In the receiving device, the electronic program guide creating unit is a first broadcast presentation unit to which the service being received belongs when video and / or audio corresponding to the received content data is output from the output unit. When a first instruction to display an electronic program guide of a different second broadcast presentation unit is received from the user, the stored contents of the storage unit are stored while continuing to output video and / or audio according to the received content data. A second broadcast presentation unit based electronic program guide is generated and displayed on the output unit, and then the cursor for indicating the selection target by the user is moved from the other position to the position on the event list. Is received from the user, the receiving unit is controlled so as to receive the broadcast signal of the service belonging to the second broadcast presentation unit. The content of the second broadcast presentation unit is updated, the electronic program guide of the second broadcast presentation unit is created based on the updated storage content of the storage unit, and is displayed on the output unit. Yes.

  According to the above configuration, the electronic program guide creation unit is configured such that the first broadcast presentation unit to which the service being received belongs when the video and / or audio corresponding to the received content data is output from the output unit. When the first instruction to display the electronic program guide of the second broadcast presentation unit different from the user is received from the user, the storage of the storage unit is continued while the video and / or audio output according to the received content data is continued. Based on the contents, an electronic program guide for the second broadcast presentation unit is created and displayed on the output unit. Therefore, when the user is viewing video and / or listening to audio of an event broadcast on a service belonging to the first broadcast presentation unit, the first broadcast to which the service being received belongs. If a first instruction to display an electronic program guide of a second broadcast presentation unit different from the presentation unit is input, the electronic program guide creation unit continues to output video and / or audio by the output unit. The second broadcast based on the storage content of the storage unit (without stopping reception of broadcast signals of services belonging to the first broadcast presentation unit by the reception unit and output of video and / or audio by the output unit) An electronic program guide for each presentation unit is created and displayed on the output unit. Therefore, the user continues to view the video and / or listen to the audio of the event broadcast by the service belonging to the first broadcast presentation unit, while the second different from the first broadcast presentation unit. An electronic program guide for each broadcast presentation unit can be viewed.

  The event information included in the broadcast signal and transmitted from the broadcast station is generally a set of event information broadcast during a predetermined limited period (for example, a period from one week after the transmission date). Each time a shorter predetermined time interval (for example, one day) elapses, new event information is added by the predetermined time interval, and past event information is deleted. In the configuration of the present invention, when the first instruction is received from the user, the second received last is based on the storage content of the storage unit while continuing to receive the service belonging to the first broadcast presentation unit. The second broadcast presentation unit electronic program guide is displayed based on the broadcast presentation unit event information. Therefore, if the time when the event information of the second broadcast presentation unit was last received is not immediately before the current time, for example, one day before, the electronic program guide of the second broadcast presentation unit displayed is the last The addition of event information that has been performed from the time of reception to the present time is not reflected. For this reason, in the displayed electronic program guide of the second broadcast presentation unit, there is a possibility that information may be lost such as some event information is missing.

  As a case where event information is lost in the electronic program guide of the second broadcast presentation unit, specifically, the following cases can be considered.

(1) When the event information of the second broadcast presentation unit has not yet been acquired (when the user purchases a new broadcast receiving device and turns on the broadcast receiving device for the first time, etc.)
(2) When a long time of a level close to the period of event information that can be acquired has elapsed since the last time when the event information of the second broadcast presentation unit was acquired (for example, BS digital television distributed every week) (When John Broadcast event information is acquired, the broadcast receiver is turned off and the broadcast receiver is turned on again for one week)
(3) The storage capacity of the storage unit (for example, a non-volatile memory) in the broadcast receiving device is limited. When a long time of a level close to a period (for example, one day) corresponding to event information has elapsed (for example, event information of the second broadcast presentation unit is stored in a nonvolatile memory capable of storing event information for one day) In the configuration, after acquiring the event information of the second broadcast presentation unit, when the broadcast receiver is turned off and the broadcast receiver is turned on again for one week)
(4) When the acquisition of event information transmitted from a broadcasting station at a predetermined period (for example, 3 minutes) has started and the time shorter than that period has elapsed (a state during the acquisition of event information)
However, when such a lack of information occurs, if the user inputs the second instruction, the electronic program guide creation unit receives the second instruction, and a plurality of pieces belonging to the second broadcast presentation unit. By updating the reception unit so as to receive broadcast signals of at least one service including event information related to all the services, the storage contents of all the plurality of services belonging to the second broadcast presentation unit in the storage unit are updated. Then, an electronic program guide for the second broadcast presentation unit is created based on the updated storage content of the storage unit and displayed on the output unit. Therefore, when necessary (for example, when the event information is missing in the electronic program guide of the second broadcast presentation unit that is displayed first, or the latest electronic program guide related to the second broadcast presentation unit is displayed). If it is desired to confirm), if the second instruction is input, it is possible to view the electronic program guide in which the information related to the service belonging to the second broadcast presentation unit is updated.

  Furthermore, according to the above configuration, the user's instruction for browsing the electronic program guide of the second broadcast presentation unit with updated information includes a cursor on the event list indicating the selection target. This is an instruction to move from another position. Therefore, when the event information is missing in the electronic program guide of the second broadcast presentation unit displayed in accordance with the first instruction, the user reads “the part where the noticed event information is missing, that is, the event If you move the cursor to a position on the list, the event information of the missing part will be added. '' If you enter such an instruction, the event information of the missing part will be added. Is done. Therefore, in the above configuration, the user can intuitively understand the operation for adding the missing event information without an instruction manual or the like.

A terrestrial digital television broadcast signal (broadcast wave) is transmitted from a terrestrial digital television broadcast station and received by a terrestrial digital television broadcast antenna.

  The digital demodulator 2 tunes to the channel of the desired service to extract the digital broadcast signal of the desired service from the digital broadcast signal received by the antenna 1 and to convert the digital broadcast signal into the baseband bit stream signal. Demodulate. The operation of extracting the digital broadcast signal of the desired service by tuning to the digital broadcast wave of the channel of the desired service is called channel selection. The digital demodulation unit 2 selects a service to be selected (tuned) in accordance with an instruction from the channel selection control unit 15 described later.

  As described above, the digital broadcast signal includes content data such as video data and audio data, and program arrangement information. Therefore, the bit stream signal demodulated by the digital demodulator 2 also includes content. Data and program arrangement information are included. The bit stream signal demodulated by the digital demodulation unit 2 is obtained by multiplexing a bit stream signal of event content data, a bit stream signal of program arrangement information, and the like.

  The demultiplexer 9 extracts a bit stream signal of program arrangement information from the multiplexed bit stream signal demodulated by the digital demodulator 2. That is, the demultiplexer 9 converts the multiplexed bit stream signal into a bit stream signal of video information (moving image information, still image information, character information, etc.), a bit stream signal of audio information, a bit stream signal of program arrangement information, etc. To separate. The demultiplexer 9 stores the program arrangement information in the program arrangement information storage unit 5. Further, the demultiplexer 9 sends a bit stream signal of video information and audio information to the AV decoder 4. Note that the program arrangement information included in the bit stream signal generally relates to EPG for about one week (for example, eight days) in the case of BS digital television broadcasting. The program arrangement information includes information on the event such as the name of the event, the broadcast date and time of the event, the content of the event, and the performer of the event.

  The AV decoder 4 performs a process of decoding the bit stream signal of the video information (compressed video information) sent from the demultiplexer 9 into a video signal in a format that can be processed by the display panel 7, and obtained by the process. A video signal is sent to an image composition unit 12 (to be described later) via a display control unit 13 (to be described later), and a bit stream signal of audio information (compressed audio information) sent from the demultiplexer 9 can be processed by the speaker 6. The audio signal is decoded into a format and sent to the speaker 6 via the audio control unit 11. The speaker 6 outputs sound according to the sound signal sent from the AV decoder 4. For example, MPEG (Motion Picture Experts Group) -2 Video is used as the compression format of the compressed video information included in the broadcast signal. For example, MPEG is used as the compression format of the compressed audio information included in the broadcast signal. -2 Use Audio AAC. These compression formats are not limited to these formats. For example, MPEG-4 Visual and H.264, which are international standard systems for moving picture coding technology. H.264 (MPEG-4 AVC) or the like may be used as a compression format of video information.

  The voice control unit 11 stops outputting the voice signal to the speaker 6 based on an instruction from the EPG creation unit 10 described later.

  The display control unit 13 stops the output of the video signal to the image composition unit 12 based on an instruction from the EPG creation unit 10 described later, and as a result, the video of the event corresponding to the received broadcast signal is displayed. The display on the display panel 7 is stopped.

  The program sequence information storage unit 5 stores a bit stream signal of program sequence information extracted by the demultiplexer 9.

  The remote control light receiving unit 14 receives a signal according to an instruction input by the user to the external remote control 8 from the external remote control 8 using infrared rays, and determines an instruction input by the user to the remote control 8 based on the received signal. An instruction signal corresponding to the instruction is sent to the control unit 3.

  The control unit 3 receives a user instruction to display an EPG as an instruction signal, and comprehensively controls operations of various components in the digital broadcast television 100 based on the instruction signal. The control unit 3 includes an EPG creation unit 10, an image composition unit 12, and a channel selection control unit 15.

  The EPG creation unit 10 divides a plurality of available services into a plurality of broadcast presentation units, and based on the program arrangement information stored in the program arrangement information storage unit 5 (more specifically, the EIT included in the SI of the program arrangement information) Based on the above, a plurality of EPG image signals for each broadcast presentation unit are created while being switched in accordance with a user instruction. The EPG indicates a list of a plurality of services belonging to a corresponding broadcast presentation unit and a list of the plurality of services. Here, there are three broadcast presentation units: BS digital broadcast, CS digital broadcast, and terrestrial digital television broadcast, which have different operational rules (standards) related to the event information distribution method. Therefore, in the present embodiment, the EPG creation unit 10 creates one by switching between an EPG for terrestrial digital television broadcast, an EPG for BS digital broadcast, and an EPG for CS digital broadcast. In the present embodiment, the EPG is a matrix-shaped EPG in which event information is arranged in the service ID order (channel number order) in the vertical direction, and the event information is arranged in time order in the horizontal direction as a time axis. is there. The EPG creation unit 10 creates an EPG image signal so that the display panel 7 displays at least a part corresponding to a part of the services of all EPGs that can be used in one broadcast presentation unit. The EPG creation unit 10 sends the created image signal of the EPG screen to the image composition unit 12.

  When receiving an instruction (second instruction) for moving the cursor from the service display unit of the EPG screen to the event display unit via the remote control light receiving unit 14 from the remote control 8, the EPG creation unit 10 broadcasts the event being viewed. An instruction to acquire program arrangement information of another broadcast presentation unit different from the broadcast presentation unit to which the service belongs belongs to the channel selection control unit 15 and the program arrangement information acquired and stored in the program arrangement information storage unit 5 is transmitted. By reading, program arrangement information of another broadcast presentation unit different from the broadcast presentation unit to which the service broadcasting the event being viewed belongs is acquired.

  When the EPG creation unit 10 receives an instruction (second instruction) for moving the cursor from the service display unit on the EPG screen to the event display unit via the remote control light receiving unit 14 from the remote control 8, the EPG creation unit 10 and the voice control unit 11 and An instruction to stop the output of the audio signal to the speaker 6 and the output of the video signal to the image composition unit 12 is sent to the display control unit 13, and as a result, the display of the event video on the display panel 7, And the output of the sound of the broadcast event in the speaker 6 is stopped.

  When the EPG creation unit 10 receives an instruction to move the cursor from the remote control 8 via the remote control light receiving unit 14 (instructions by the cursor keys 26 to 29), the EPG creation unit 10 moves the cursor based on the instruction to move the EPG screen. The process to display on top is performed. The EPG creation unit 10 also performs highlight display processing for the service display unit and the date / time display unit.

  The image synthesis unit 12 synthesizes the image signal of the EPG screen sent from the EPG creation unit 10 with the video signal of the event sent from the AV decoder 4, and outputs the obtained video signal to the display panel 7. As a result, the image composition unit 12 causes the display panel 7 to display the EPG screen image created by the EPG creation unit 10 on the display panel 7 so as to be superimposed on the video corresponding to the video signal from the AV decoder 4 (video of the broadcast event). By displaying in this way, the user can check the EPG while viewing the broadcast event. In the normal viewing state, since the image signal of the EPG screen is not sent from the EPG creation unit 10, the image composition unit 12 outputs the video signal sent from the AV decoder 4 to the display panel 7 as it is.

  The channel selection control unit 15 receives an instruction to select a service or a broadcast presentation unit switching instruction to be described later from the remote controller 8 via the remote control light receiving unit 14, and switches the channel to be selected according to the instruction. The digital demodulator 2 is controlled. Further, the channel selection control unit 15 can also receive an instruction from the EPG creation unit 10, and other broadcast presentations different from the broadcast presentation unit to which the service broadcasting the event being viewed belongs from the EPG creation unit 10. When receiving an instruction to acquire the unit program arrangement information, the digital demodulator 2 is controlled so as to switch the channel to be selected to at least one channel transmitting the program arrangement information of another broadcast presentation unit.

  The display panel 7 outputs a video signal including an event video and / or an EPG screen sent from the image synthesis unit 12 as a video. The display panel 7 is not particularly limited, and is a liquid crystal display panel, a plasma display panel, an organic EL display panel, or the like. Further, instead of the display panel 7, a CRT (cathode ray tube) display, a projection display device (projector), or the like may be used.

  As shown in FIG. 2, the remote control 8 includes a key group for a user to input an instruction to the digital broadcast television 100, and sends signals representing various instructions to the remote control light receiving unit 14 in accordance with the operation of the key group. It is. The key group includes a program guide key 20 for displaying an EPG screen on the display panel 7 of the digital broadcast television 100, three broadcast switching keys 21, and an event at the position of the cursor on the EPG screen (the currently selected event). ) For selecting or reserving a channel, an up cursor key 26 for moving the cursor on the EPG screen up, a left cursor key 27 for moving the cursor on the EPG screen to the left, on the EPG screen A right cursor key 28 for moving the cursor to the right, and a lower cursor key 29 for moving the cursor on the EPG screen downward. For example, when the program guide key 20 is pressed while the event video is displayed, the remote controller 8 instructs to start an EPG screen (EPG screen 30 described later) of the broadcast presentation unit to which the service broadcasting the event belongs. Send a signal representing.

  The broadcast switching key 21 is a key for instructing switching of a broadcasting network, and is composed of three keys: a terrestrial digital television broadcasting key 22, a BS digital broadcasting key 23, and a CS digital broadcasting key 24.

  The broadcast switching key 21 inputs an instruction to switch the EPG created by the EPG creation unit 10 from one broadcast presentation unit EPG to another broadcast presentation unit EPG when the EPG is superimposed on the video of the broadcast event. Acts as a key.

  When the broadcast switching key 21 displays a broadcast event video without displaying an EPG, the channel selected by the digital demodulator 2 is changed from one broadcast presentation unit channel to another broadcast presentation unit channel. Functions as a key to input an instruction to switch to. There is an input from the broadcast switching key 21 corresponding to a broadcast presentation unit different from the broadcast presentation unit of the broadcast event currently being displayed in a state where the broadcast event video is displayed on the display panel 7 without displaying the EPG. In this case, the digital demodulator 2 acquires content data of an event being broadcast in synchronization with one service of a broadcast presentation unit (for example, CS digital broadcast) corresponding to the input broadcast switch key 21, and The event video is displayed on the display panel 7. For example, when the CS digital broadcast key 24 is selected, the digital demodulator 2 acquires content data of an event being broadcast in synchronization with one service of CS digital broadcast, and displays a video of the event being broadcast on the display panel. 7 is displayed.

  Next, EPG display processing in the digital broadcast television 100 will be described in detail.

  In the following description, the available BS digital broadcasting services are five services with service IDs 101, 102, 103, 141, 201, and TSIDs (transport stream IDs) of these services are 4000, 4000, respectively. Suppose that it is 4001,5000,6000. As shown in Table 1, the program arrangement information storage unit 5 of the digital broadcast television 100 stores program arrangement information relating to a plurality of services included in each broadcast presentation unit (in this example, network ID, service ID, TS ID, And have a list of frequencies).

  Further, in the following description, the available terrestrial digital television broadcast services are three-digit numbers (numbers presented to the user instead of service IDs in terrestrial digital television broadcasts) of 011,021, 041,061. Assume that there are four services.

  The digital broadcast television 100 normally displays a video of the selected event without displaying an EPG on the display panel 7, that is, a state in which the user is viewing the event; State)). In this normal viewing state, a digital broadcast signal is received by the antenna 1 and demodulated into a baseband bit stream signal by the digital demodulator 2. Then, the demodulated bit stream signal is separated into content data (element signal) and program arrangement information by the demultiplexer 9. The content data is a bit stream of video information and audio information in television broadcasting, and a bit stream of audio information in radio broadcasting. The bit stream signal of the video information is decoded by the AV decoder 4 and then sent to the display panel 7 via the image synthesis unit 12 and displayed on the display panel 7 as a video. The bit stream signal of the audio information is decoded by the AV decoder 4 and then sent to the speaker 6 and is output from the speaker 6 as audio. The program arrangement information is stored in the program arrangement information storage unit 5.

  As described above, the digital broadcast television 100 receives the program arrangement information and stores it in the program arrangement information storage unit 5. The program arrangement information may be always received, but is preferably received at a timing that does not hinder the output of video and audio, for example, when reception of a digital broadcast signal is started.

  A broadcast signal of one service of terrestrial digital television broadcasting includes program arrangement information (each station SI) relating to only that service. Therefore, the digital broadcast television 100 performs the channel scan by the digital demodulator 2 at the start of reception of the terrestrial digital television broadcast, thereby obtaining the program arrangement information (each station SI) of all the services of the terrestrial digital television broadcast in the viewing area. The program arrangement information is received and stored in the program arrangement information storage unit 5. Each time each service is selected and the digital demodulator 2 receives the program arrangement information of another service, the program arrangement information stored in the program arrangement information storage unit 5 is updated with the received program arrangement information. .

  Also, a broadcast signal of one service of BS digital broadcast or CS digital broadcast includes event information (all-station SI) regarding all services belonging to the same network. Therefore, the digital broadcast television 100 receives a predetermined one service belonging to a network (BS digital broadcast, CS1 network, or CS2 network) received by the digital demodulator 2 at the start of reception of the BS digital broadcast, the CS1 network, and the CS2 network. (For example, a promotion channel with a short data retransmission cycle) is selected, program arrangement information (all stations SI) of all services of the network is received, and the received program arrangement information (all stations SI) is received in the program arrangement information storage unit 5. Remember me.

  In this normal viewing state, the digital broadcast television 100 stands by without starting the EPG screen until the user presses the program guide key 20 of the remote controller 8.

  When the user presses the program guide key 20 of the remote controller 8, that is, when the instruction signal instructing activation of the EPG screen is received from the remote control light receiving unit 14, the digital broadcast television 100 receives the program received from the digital broadcast station. The EPG is displayed on the display panel 7 based on the arrangement information.

  More specifically, first, the EPG creation unit 10 receives a signal instructing activation of the EPG screen from the remote control light receiving unit 14, and information such as service information and event information (event name, etc.) to be displayed on the EPG screen. Is read from the program array information storage unit 5, and an image signal of the EPG screen is created based on the read information. Then, the image synthesizing unit 12 synthesizes the generated image signal of the EPG screen with the video signal of the event being viewed and outputs it to the display panel 7, whereby the event of viewing the EPG screen on the display panel 7. Overlaid on the video.

  As a result, as shown in FIG. 3 or FIG. 4, it is broadcast on each of a plurality of services belonging to the broadcast presentation unit being viewed (in this example, BS digital broadcast, CS digital broadcast, or terrestrial digital television broadcast). An EPG screen 30 (basic screen) showing the event information is displayed on the screen 7a of the display panel 7 (see FIG. 1) so as to be superimposed on the event video 35 being viewed. FIG. 3 is an example of an EPG screen 30 relating to BS digital broadcasting, and FIG. 4 is an example of an EPG screen 30 relating to terrestrial digital television broadcasting.

  As shown in FIG. 3 or FIG. 4, the EPG screen 30 includes an EPG display unit including a service display unit 31, an event display unit 32, and a date / time display unit 33, and other parts.

  The service display unit 31 shows a list of services that can be viewed. In this example, four service IDs (channel numbers) are arranged along the vertical direction. In the service display unit 31, one of the service IDs is always selected. When the EPG screen 30 is activated from the normal viewing state, the service ID corresponding to the currently viewed event is selected. The currently selected service ID is highlighted. Therefore, when the EPG screen 30 is activated from the normal viewing state, the service ID corresponding to the currently viewed event is highlighted.

  When switching from one broadcast presentation unit EPG to another broadcast presentation unit EPG, the cursor 34 is displayed on the currently selected service ID in the service display unit 31, as described later. When the cursor 34 is present on the service display unit 31, the cursor 34 can be moved up and down on the service display unit 31 as the user presses the up and down cursor keys 26 and 29 of the remote controller 8. However, when the user presses the upper cursor key 26 of the remote controller 8 after the cursor 34 reaches the top, the service display unit 31 is scrolled downward by one line without moving the cursor 34. Similarly, when the user presses the lower cursor key 29 of the remote controller 8 after the cursor 34 reaches the bottom, the service display unit 31 is scrolled upward by one line without moving the cursor 34. By scrolling up and down in this way, the user can know all services (service IDs in this example) belonging to the broadcast presentation unit corresponding to the event currently being viewed. Instead of the service ID, a service logo or a service name may be displayed.

  The event display unit 32 is broadcasting or scheduled to broadcast on a plurality of services belonging to the same broadcast presentation unit (in this example, terrestrial digital television broadcasting, BS digital broadcasting, or CS digital broadcasting) as the channel (service) being received. A list of events (a list of event information such as event names) is displayed in chronological order. In this example, the event display unit 32 is arranged such that the time axis is the horizontal axis, and the horizontal row displaying the event information for each service corresponds to the service display unit 31. In addition, event information such as an event name is displayed in a cell provided for each event. The event display unit 32 is arranged on the right side of the service display unit 31.

  The time width of the EPG displayed on the event display unit 32 may be set as appropriate, for example, 3 hours or 6 hours, but is 3 hours in the examples of FIGS. The number of EPG channels (services) displayed on the event display unit 32 is not particularly limited, but is 4 channels (services) in the examples of FIGS. 3 and 4.

  In the event display section 32, any one cell is always selected. When the EPG screen 30 is activated from the normal viewing state, a cell corresponding to the event currently being viewed is selected. Then, the cursor 34 is displayed on the cell corresponding to the currently selected event. Therefore, when the EPG screen 30 is activated from the normal viewing state, the cursor 34 is displayed on the cell corresponding to the event currently being viewed.

  When the cursor 34 is present on the event display unit 32, the user moves the cursor 34 to the position of the cell corresponding to the desired event using the cursor keys 26 to 29 of the remote controller 8, so that the event is displayed. Can be selected. That is, in the event display section 32, when the user presses the right cursor key 28, the cursor 34 moves up one event to the right, and when the user presses the left cursor key 27, the cursor 34 moves up one event to the left. When the user presses the up cursor key 26, the cursor 34 moves up one event, and when the user presses the down cursor key 29, the cursor 34 moves up one event. It has become. However, when the user presses the upper cursor key 26 of the remote controller 8 after the cursor 34 reaches the top, the service display unit 31 is scrolled downward by one line without moving the highlight display unit. Similarly, when the user presses the lower cursor key 29 of the remote controller 8 after the cursor 34 reaches the bottom, the service display unit 31 is scrolled upward by one line without moving the cursor 34. By scrolling up and down in this way, the user can know all services (service IDs in this example) belonging to the broadcast presentation unit corresponding to the event currently being viewed. Instead of the service ID, a service logo or a service name may be displayed. Also, the broadcast station name may be displayed together with the service ID.

  The date and time display unit 33 includes a plurality of cells indicating time zones corresponding to the time axis of the event display unit 32 in order to visually indicate the broadcast time of each event displayed on the event display unit 32. In the date and time display section 33, when there is an event selected on the EPG, a cell in a time zone corresponding to the selected event is highlighted, and there is no event selected on the EPG. If there is an event being viewed, the cell in the time zone corresponding to the event being viewed is highlighted. The date and time display unit 33 is arranged on the event display unit 32.

  The other part of the EPG screen 30 has a broadcast presentation unit being displayed (“BS” (BS digital broadcast) in the example of FIG. 3, “Terrestrial D” (digital terrestrial television broadcast) in the example of FIG. 4). The current date and time (in this example, “1/13 AM10: 44”) is displayed.

  The user can use the EPG screen 30 to view an event he / she wants to watch or to reserve an event. That is, after the EPG screen 30 shown in FIGS. 3 and 4 is displayed, the user uses the cursor keys 26 to 29 to move the cursor 34 onto a cell of a desired event, selects the event, and determines the key 25. By pressing, the selected event can be viewed or reserved. The digital broadcast television 100 selects a selected event when an event being broadcast is selected, and shifts to a reservation selection screen when an unbroadcast event is selected. This reservation selection screen is used to select whether to make a viewing reservation, a recording reservation, or no reservation. When the user makes this selection, the digital broadcast television 100 performs reservation processing or reservation cancellation processing according to the selection.

  Further, the EPG screen 30 disappears when the user presses the end key of the remote controller 8. That is, when the user presses the end key of the remote controller 8, the display panel 7 returns to the state where the video of the event being selected is displayed (normal viewing state).

  Next, with regard to the flow of processing for displaying the EPG of another broadcast presentation unit in a state where the EPG of the broadcast presentation unit is superimposed on the video of the event of the broadcast presentation unit, FIG. 3, FIG. 4, FIG. This will be described with reference to the flowchart of FIG. 7 and FIGS. FIG. 6 is a flowchart showing a flow of processing for displaying an EPG of another broadcast presentation unit. FIG. 7 shows a process flow when the EPG of another broadcast presentation unit is displayed by the process of FIG. 6 and the right cursor key 28 of the remote controller 8 is pressed in a state where the cursor 34 is present in the service display unit 31. It is a flowchart which shows.

  Here, the EPG of the BS digital broadcast as the second broadcast presentation unit is displayed with the EPG of the terrestrial digital television broadcast superimposed on the video of the event of the digital terrestrial television broadcast as the first broadcast presentation unit. A flow of processing to be displayed will be described. Although not described here, the processing flow is the same even if the first broadcast presentation unit and the second broadcast presentation unit are other combinations.

  Here, it is assumed that program arrangement information (all-station SI) of all services of BS digital broadcasting has been received and stored in the program arrangement information storage unit 5 in advance. In addition, a channel scan of terrestrial digital television broadcasting is performed in advance, and program arrangement information (each station SI) of all services of terrestrial digital television broadcasting in the viewing area is received and stored in the program arrangement information storage unit 5 And

  Further, as shown in FIG. 4, based on the program arrangement information of the digital terrestrial television broadcast stored in the program arrangement information storage unit 5, the digital terrestrial television broadcast EPG receives the event video 35 (received by the digital terrestrial television broadcast). It is assumed that the sound of the event of digital terrestrial television broadcasting (the sound corresponding to the received content data) is output from the speaker 6.

  Next, a user instruction to display an EPG of a broadcast presentation unit different from the broadcast presentation unit of the currently displayed EPG in a state in which the EPG of the terrestrial digital television broadcast is superimposed on the event video 35 of the terrestrial digital television broadcast, That is, when the user presses the BS digital broadcast key 23 on the remote controller 8, the digital broadcast television 100 performs a process of switching the EPG to be displayed from the EPG of the terrestrial digital television broadcast to the EPG of the BS digital broadcast (EPG switching process). (S3 / S4).

  That is, first, the EPG creation unit 10 waits until one of the plurality of broadcast presentation units, that is, one of the three broadcast switching keys 21 (22 to 24) is pressed (NO in S1). When one of the three broadcast switching keys 21 (22 to 24) is pressed (YES in S1), the broadcast presentation unit corresponding to the pressed broadcast switching key 21 is the broadcast presentation unit of the currently displayed EPG. (S2).

  In this case, the broadcast presentation unit (BS digital broadcast) corresponding to the pressed broadcast switching key 21 (BS digital broadcast key 23) is different from the currently displayed EPG broadcast presentation unit (terrestrial digital television broadcast). , The process proceeds to the EPG display process of the BS digital broadcast of S3 and S4. If the broadcast presentation unit corresponding to the pressed broadcast switching key 21 is the same as the broadcast presentation unit of the currently displayed EPG, the process ends.

  In the EPG switching process in S3 and S4, first, the EPG creation unit 10 first records past program arrangement information (one broadcast digital broadcast) related to the broadcast presentation unit (BS digital broadcast) corresponding to the pressed broadcast switch key 21 (BS digital broadcast key 23). The program arrangement information obtained when the BS digital broadcast was received most recently is obtained from the program arrangement information storage unit 5 (S3). Note that the information acquired at this time may be only the EIT.

  Next, the EPG creation unit 10 includes an EPG screen including a service display unit 31 and an event display unit 32 related to BS digital broadcasting based on EIT included in the program arrangement information of BS digital broadcasting acquired from the program arrangement information storage unit 5. 30 is created and displayed on the display panel 7 (S4).

  That is, the EPG creation unit 10 corresponds to the pressed broadcast switch key 21 (BS digital broadcast key 23) instead of the currently displayed EPG screen 30 (EPG screen 30 of terrestrial digital television broadcast shown in FIG. 4). The image signal of the EPG screen 30 to be processed, that is, the EPG screen of BS digital broadcasting is created and sent to the image composition unit 12. Then, the image synthesis unit 12 synthesizes the image signal of the EPG screen 30 of the BS digital broadcast created by the EPG creation unit 10 with the video signal of the event video 35 of the terrestrial digital television broadcast, so that the BS digital broadcast The EPG screen 30 is superimposed and displayed on the event video 35 of the terrestrial digital television broadcast.

  Further, the EPG creation unit 10 displays the cursor 34 on the service display unit 31 of the EPG screen 30 (S4).

  As described above, as shown in FIG. 8, the BS digital broadcast EPG screen 30 in which the cursor 34 is arranged on the service display unit 31 is superimposed on the event video 35 of the terrestrial digital television broadcast on the display panel 7. Is displayed.

  In the EPG switching process of S3 and S4, the EPG creation unit 10 does not cause the channel selection control unit 15 to perform channel selection control of the digital demodulation unit 2, and does not allow the channel selection control unit 15 to perform the service (viewing / listening) The broadcast signal of the service that broadcasts the middle event) is continued, and the video output of the event by the display panel 7 and the sound output of the event by the speaker 6 are continued. Therefore, video and audio are flowing as they are.

  Therefore, the digital broadcast television 100 can display an EPG related to a broadcast presentation unit different from the broadcast presentation unit of the broadcast event while displaying the video of the terrestrial digital television broadcast event. Therefore, the digital broadcast television 100 can superimpose and display the BS digital broadcast EPG without erasing the video and audio of the terrestrial digital television broadcast event currently being viewed. Since the video and audio of the terrestrial digital television broadcast event currently being viewed do not disappear, the user can watch the terrestrial digital television broadcast event currently being viewed while viewing the EPG of the BS digital broadcast. Can be viewed.

  By browsing the EPG of the BS digital broadcast displayed at this time, the user can obtain various useful information.

  First, if all event EITs corresponding to all event cells of the event display unit 32 of the EPG screen 30 have been acquired, all events of the event display unit 32 of the EPG screen 30 of BS digital broadcasting are already in this state. Event information is displayed in the cell. Therefore, the user can obtain information on all events broadcast on the BS digital broadcast from the event display section 32 of the EPG screen 30 of the BS digital broadcast.

  On the other hand, if the EIT of some events among the events corresponding to the event cell of the event display unit 32 of the EPG screen 30 has not been acquired, as shown in FIG. The EPG screen 30 in which the event information of the event cell to be deleted is displayed. Even if the EPG screen 30 shown in FIG. 8 is left displayed, the missing event cell is not filled. However, even in that case, the user can obtain information on a part of an event broadcast by BS digital broadcasting from the EPG shown in FIG.

  Even if the event information is not displayed on the event display unit 32, the user can check what service is available by browsing the service display unit 31 while scrolling up and down as necessary ( Channel number (service ID) of services that can be viewed can be confirmed).

  In step S4, for example, a routine shown in the flowchart of FIG. 6 is called.

  When this routine is called, a service with a service ID is designated based on a predetermined rule. In this example, the 103ch service is designated. The rule for designating a service at the time of calling is “if the service ID is 103, designate the service with the service ID 103, and if there is no 103ch, designate the service having the lowest service ID”. Decide in advance.

  Next, the EPG creation unit 10 stores the service designated at the time of calling this routine as the service X (S11).

  Next, the EPG creation unit 10 acquires the current date and time from the TOT in the program arrangement information stored in the program arrangement information storage unit 5 or the internal clock (S12). Then, the EPG creation unit 10 draws the date display unit 33 based on the acquired date (S13). That is, the EPG creation unit 10 creates an image of the date and time display unit 33 and displays it on the display panel 7.

  Next, the EPG creation unit 10 draws the service display unit 31 based on the SDT in the program sequence information stored in the program sequence information storage unit 5 (S14). That is, the EPG creation unit 10 creates an image of the service display unit 31 and displays it on the display panel 7.

  Next, the EPG creation unit 10 draws the event display unit 32 based on the EIT in the program sequence information stored in the program sequence information storage unit 5 (S15). That is, the EPG creation unit 10 creates an image of the event display unit 32 and displays it on the display panel 7.

  Next, the EPG creation unit 10 displays a cursor on the service X in the service display unit 31 (S16).

  If there is an instruction to move the cursor 34 to the event display section 32 after the EPG switching process of S3 and S4 (S5), that is, when the user presses the right cursor key 28 of the remote controller 8, the EPG update process of S6 to S9 is performed. Transition.

  In the EPG update process of S6 to S9, first, the EPG creation unit 10 sends a video signal and an audio signal according to the received content data to the display panel 7 and the speaker 6 to the display control unit 13 and the audio control unit 11. In response to the instruction, the display control unit 13 and the audio control unit 11 send a video signal and an audio signal corresponding to the received content data from the AV decoder 4 to the display panel 7 and the speaker 6. As a result, the output of the event video 35 and audio being viewed according to the received content data is stopped (muted) (S6).

  Also, the EPG creation unit 10 moves the cursor 34 from the service display unit 31 to the event display unit 32 (S7).

  As a result, as shown in FIG. 9, the cursor 34 moves from the service display unit 31 to the event display unit 32, and the event video 35 being viewed is erased.

  Furthermore, the digital broadcast television 100 selects one service in the broadcast presentation unit corresponding to the pressed key (S8). In this case, the digital broadcast television 100 selects one service of BS digital broadcast. That is, the EPG creation unit 10 sends an instruction to select one BS digital broadcast service to the channel selection control unit 15, and the channel selection control unit 15 follows this instruction to select one BS digital broadcast service. The digital demodulator 2 is controlled to select a channel. As a result, a broadcast signal including the latest program arrangement information of all BS digital broadcast services is received by the digital demodulation unit 2 and stored in the program arrangement information storage unit 5. Therefore, the program arrangement information of all BS digital broadcast services stored in the program arrangement information storage unit 5 is updated to the latest one. Then, the EPG creation unit 10 acquires the latest program arrangement information of all the services related to the BS digital broadcast from the program arrangement information storage unit 5 (S8), and the display contents of the EPG of the BS digital broadcast displayed on the display panel 7 Is updated in accordance with the program arrangement information regarding the BS digital broadcast in the acquired program arrangement information storage unit 5 (S9).

  In this example, one BS digital broadcast service is selected, the BS digital broadcast signal is received, the latest EIT is acquired, and the content of the EPG is updated as the EIT is acquired. Therefore, after pressing the BS digital broadcast key 23 on the remote controller, EIT is acquired for all events broadcast within a predetermined period (one week in the case of television broadcast) for all BS digital broadcast services, and EIT is acquired. As a result, the content of the EPG of the BS digital broadcast displayed on the display panel 7 is updated. Therefore, if the EPG screen 30 of the BS digital broadcast lacking some event information shown in FIG. 9 is left displayed, the EPG screen of the BS digital broadcast shown in FIG. 30 is displayed.

  As described above, the user browses the EPG screen shown in FIG. 3 and inputs BS digital data only by inputting an instruction to move the cursor 34 to the event display unit 32 (operating the right cursor key 28 of the remote controller 8). Get the latest information on all broadcast events.

  In addition, by an easy-to-understand operation of “move the cursor from the service display section to the event display section”, event information that has not been displayed because EIT has not been acquired can be additionally displayed on the electronic program guide for other broadcast presentation units. Easy to use. That is, in general, when an event information is missing in an electronic program guide of another broadcast presentation unit, the user moves “the cursor to a portion where the noticed event information is missing, and some change occurs. It will happen. ” Therefore, if the user performs an operation of moving the cursor to the event display unit according to such intuition (operation of the right cursor key 28), event information of the missing part is added. Therefore, the user can intuitively perform an operation for adding missing event information without looking at an instruction manual or the like.

  In the steps S7 and S8, for example, a routine shown in the flowchart of FIG. 7 is called.

  First, the EPG creation unit 10 stores the service selected in the service display unit 31, that is, the service at the position where the cursor 34 exists in the service display unit 31 as the service X (S21).

  Next, the EPG creation unit 10 acquires the current date and time from the TOT in the program arrangement information stored in the program arrangement information storage unit 5 or the internal clock (S22).

  Next, the EPG creation unit 10 highlights the date and time unit including the current date and time in the date and time display unit 33 (S23).

  Next, the EPG creation unit 10 deletes the cursor 34 existing on the service X in the service display unit 31 (S24).

  Next, the EPG creation unit 10 highlights the service X in the service display unit 31 (S25).

  Next, if an event being broadcast on the service X at the current date and time is displayed on the event display unit 32, the cursor 34 is displayed on the event (S26). On the other hand, if the event currently being broadcast on the service X is not displayed on the event display unit 32, the cursor 34 is not displayed on the event (S26).

  Next, the BS digital broadcast service X is selected (S27). That is, the EPG creation unit 10 sends an instruction to select the BS digital broadcast service X to the channel selection control unit 15, and the channel selection control unit 15 selects the BS digital broadcast service X according to this instruction. The digital demodulator 2 is controlled so as to be stationed.

  By the way, in step S8, one service of the broadcast presentation unit corresponding to the pressed key is selected. However, as another example, after selecting one service, the broadcast presentation unit is selected. When configured from a plurality of networks (for example, “CS” or “terrestrial D”), after a predetermined time has elapsed, the services of other networks belonging to the broadcast presentation unit are selected in order, The operation of waiting for the elapse of a predetermined time may be repeated until the services of all networks in the broadcast presentation unit are selected. For example, when the broadcast presentation unit is “CS” and one service to be initially selected belongs to the CS2 network, the service belonging to the CS1 network may be selected after a predetermined time has elapsed. Good. At this time, the method for determining the service belonging to CS1 is determined in advance, such as “001 if 001 exists, youngest service ID if none”. The same applies to other networks. Similarly, for example, when the broadcast presentation unit is “terrestrial D”, “terrestrial D” is composed of four networks 1 to 4 on the ground, and one service to be selected first belongs to the three terrestrial networks, Waiting for elapse of time → selecting a service belonging to the terrestrial 4 network → waiting for elapse of a predetermined time → selecting a service belonging to the terrestrial 1 network → waiting for elapse of a predetermined time → selecting a service belonging to the terrestrial 2 network, It may be operated as follows.

  Further, in the flowchart of FIG. 5, step S9 is executed after step S8, but step S9 may be executed every time EIT is acquired.

  As described above, in the digital broadcast television 100 according to the present embodiment, in a state where an EPG of a certain broadcast presentation unit is superimposed on the event video, an instruction to start displaying an EPG of another broadcast presentation unit is given to the user. Is entered, the cursor 34 is first arranged on the service display unit 31. At this time, the digital broadcast television 100 according to the present embodiment continues to output the video and audio of the event that was being viewed at the time when the user inputs the instruction, and another broadcast on the video of the event. The presentation unit EPG is displayed in a superimposed manner.

  Accordingly, the user can view an EPG of another broadcast presentation unit different from the broadcast presentation unit to which the event belongs while viewing an event of a service belonging to a certain broadcast presentation unit, which improves usability. That is, the user can continue viewing the event even when viewing the EPG of another broadcast presentation unit (but before moving the cursor from the service display unit to the event display unit).

  On the EPG displayed at this time, information about an event for which EIT has already been acquired (an event for which EIT is stored in the program array information storage unit) is displayed. Therefore, when there is an event that has not acquired EIT, information on the event that has not acquired EIT is not displayed on the event display section of the EPG. However, even in this case, if some event information is displayed on the event display section of the EPG, the user can watch the event of the service belonging to a certain broadcast presentation unit, and the event of another broadcast presentation unit. Since a part of information can be browsed, it is useful for the user. Further, even if no event information is displayed on the event display portion of the EPG, the service information is displayed on the service display portion of the EPG. Thereby, the user can confirm the channel number (service ID) of the viewable service belonging to another broadcast presentation unit while viewing the event of the service belonging to a certain broadcast presentation unit. For example, while viewing an event, it is possible to confirm that there is a viewable service having a channel number (service ID) such as 101, 102, 103, 141,.

  When the number of services that can be viewed is small, all of the services that can be viewed belonging to other broadcast presentation units are displayed on the service display section of the EPG. Therefore, the user can check all the services that can be viewed belonging to other broadcast presentation units while viewing the events of the services belonging to a certain broadcast presentation unit.

  On the other hand, there are many services that can be viewed, and only some services may be displayed on the service display section of the EPG. In the digital broadcast television 100 according to the present embodiment, when the user moves the cursor up and down using the up and down cursor keys, the screen is scrolled up and down to display services that are not displayed. Therefore, even in this case, the user can use the up / down cursor keys to move the cursor up / down to view a service event belonging to another broadcast presentation unit while viewing the service event belonging to another broadcast presentation unit. All of these can be confirmed by the user.

  Further, in the digital broadcast television 100 according to the present embodiment, when the video and audio of the event is continuously output and the EPG of another broadcast presentation unit is superimposed on the video of the event, the user can When an operation of moving the cursor from the service display unit to the event display unit is performed, at least one service belonging to another broadcast presentation unit is selected, and program arrangement information such as EIT is acquired. Also, the digital broadcast television 100 acquires information (specifically, information corresponding to SI such as EIT) related to an event broadcast by at least one service belonging to another broadcast presentation unit by this channel selection, The contents of the EPG are updated. Thereby, when there is a missing event information in the displayed EPG because there is an event that has not yet been acquired, the user performs an operation of moving the cursor from the service display unit to the event display unit, It is possible to add display of event information (information related to events for which EIT has not been acquired) for missing portions. As a result, the user can browse the EPG in which the missing part is filled.

  Next, for comparison between the present invention and the prior art, EPG display processing in the conventional liquid crystal television “AQUAS G series” (hereinafter referred to as “conventional device”) will be described with reference to FIGS. To do. Again, as shown in Table 1, the storage unit displays a list of program arrangement information (in this example, network ID, service ID, TS ID, and frequency) related to a plurality of services included in each broadcast presentation unit. Suppose you have it. Also here, there are four terrestrial digital television broadcasting services that can be used, three-digit numbers (numbers presented to the user instead of service IDs in terrestrial digital television broadcasting) of 011,021, 041,061. It shall be a service.

  Here, a case will be described in which an EPG for terrestrial digital television broadcasting is displayed while an EPG for terrestrial digital television broadcasting is displayed and then an EPG for terrestrial digital broadcasting is switched to an EPG for BS digital broadcasting.

  First, when the user presses the program guide key on the remote controller during viewing of an event of terrestrial digital television broadcasting, the terrestrial digital EPG is superimposed on the currently viewed video and displayed as in FIG.

  Next, when the user presses the BS digital broadcast key on the remote controller, the displayed EPG is switched from the digital terrestrial television broadcast EPG to the BS digital broadcast EPG, and the output of the video signal corresponding to the received video signal is stopped. The sound is muted (S33 / S34).

  In other words, the conventional machine waits for a key to switch to one of the broadcast presentation units (in this example, the BS digital broadcast key) (S31), and the key to switch to one of the broadcast presentation units is the EPG. When pressed, whether or not the broadcast presentation unit (BS digital broadcast in this example) corresponding to the pressed key is different from the currently displayed EPG broadcast presentation unit (terrestrial digital television broadcast in this example). Is determined (S32). If they are different, the video and audio of the event being viewed are erased (S33), and instead of the currently displayed EPG, the EPG of the broadcast presentation unit (BS digital broadcast in this example) corresponding to the pressed key Is displayed (S34).

  In S34, the conventional machine displays an EPG of BS digital broadcasting based on the EIT stored in advance. At this time, if there is an event for which EIT has not been acquired, as shown in FIG. 9, an EPG in which the information corresponding to the event is missing is displayed.

  The conventional machine then selects one service of the broadcast presentation unit corresponding to the pressed key, and the same network service as the selected one of the broadcast presentation units corresponding to the pressed key. The latest program arrangement information regarding is acquired (S35). Then, the display content of the EPG is updated in accordance with the acquired latest program arrangement information.

  In this example, one BS digital broadcast service is selected, the BS digital broadcast signal is received, the latest EIT is acquired, and the content of the EPG is updated as the EIT is acquired. Therefore, the conventional machine acquires EITs related to all events broadcast within a predetermined period (one week in the case of TV broadcasting) with all BS digital broadcasting services after pressing the BS digital broadcasting key on the remote control, As the EIT is acquired, the content of the EPG is updated. Therefore, if the EPG shown in FIG. 9 is left in the displayed state, the EPG in which the missing portion of the EPG shown in FIG. 9 is filled, for example, the EPG shown in FIG. 3 is displayed.

  In the steps of S34 and S35 for displaying the EPG of the BS digital broadcast (other broadcast presentation unit) while viewing the service of the broadcast presentation unit other than the BS digital broadcast, for example, a routine shown in the flowchart of FIG. 11 is called.

  When this routine is called, a service with a service ID is designated based on a predetermined rule. In this example, the 103ch service is designated. The rule for designating a service at the time of calling is “if the service ID is 103, designate the service with the service ID 103, and if there is no 103ch, designate the service having the lowest service ID”. Decide in advance.

  Next, the service designated at the time of calling this routine is set as service X (S41).

  Next, the current date and time are acquired (S42), and the date and time display unit is drawn based on the acquired date and time (S43).

  Next, the service display unit is drawn (S44) and the event display unit is drawn (S45).

  Next, the date and time unit including the current date and time in the date and time display section is highlighted (S46).

  Next, the service X in the service display section is highlighted (S47).

  Next, among the events belonging to the service X, if an event being broadcast at the current date and time is displayed on the event display unit, the cursor is displayed on the event. If not displayed, the cursor is not displayed (S48).

  Next, the service X is selected (S49).

  Note that the routine shown in the flowchart of FIG. 11 is also called when displaying an EP related to another broadcast presentation unit such as a CS digital broadcast instead of the BS digital broadcast. The service at the time of calling is, for example, “100 if there is 100, the youngest service ID if there is 100”, for example, “011 if there is 011” in the case of terrestrial digital broadcasting. It is determined in advance as “the youngest service ID”.

  When the current date and time is 1/13 AM 10:44 and the EPG of the BS is displayed in the flow of FIG. 11 while viewing other than the BS, if there is no unacquired EIT, it is displayed as shown in FIG. If there is an unacquired EIT, an example is shown in FIG.

  In the service display unit 31, the designated service is displayed at the top, and thereafter displayed in the order of the service list. After the last service (201) in the service list, the first service (101) is displayed. The service list is sorted in order of service ID. The display process of the service display unit 31 is the same for the digital broadcast television 100.

  As described above, in the conventional apparatus, when the BS digital broadcast EPG is displayed, the video and audio of the terrestrial digital broadcast are always interrupted. Therefore, for example, even when the user wants to check only the channel number (service ID) displayed on the EPG of the BS digital broadcast while viewing the event of the terrestrial digital broadcast, the video of the event being viewed and The sound is interrupted. On the other hand, in the digital broadcast television 100, the video and audio of the event being viewed are displayed until the user presses the right cursor key 28.

  In the digital broadcast television 100 described above, the cursor key for moving the cursor from the service display unit 31 to the event display unit 32 is the right cursor key. Because it is to the right of. Accordingly, the cursor key for moving the cursor from the service display unit 31 to the event display unit 32 can be appropriately changed according to the positional relationship of the event display unit 32 with respect to the service display unit 31. Further, the operation for moving the cursor from the service display unit 31 to the event display unit 32 is not limited to the operation using the cross key of the remote controller 8, but the operation using the cross key of the digital broadcast television 100 main body.
