Description

  The present invention relates to a broadcast receiving apparatus that receives a broadcast, and more particularly to a channel tuning control technique.

Terrestrial digital broadcasting has been started since 2003, and digitization of broadcasting is progressing. In 2006, digital terrestrial broadcasting for mobile terminals will be started.
In terrestrial digital broadcasting, a three-digit channel number is assigned to each broadcasting station in each region in each prefecture. This channel number does not overlap within the region, but this is not the case outside the region, and the channel number may overlap. Therefore, when broadcasts in a plurality of regions can be received, broadcasts from a plurality of broadcast stations having the same channel number in and outside the region may be received. In order to distinguish between them, a plurality of broadcasting stations having the same channel number are distinguished by branch numbers in the receiver, and one digit is added as a branch number to the three-digit channel number, which is managed as a four-digit channel number. . In this case, the user inputs a 4-digit number with a remote controller or the like in order to select each broadcast channel.

  In terrestrial digital broadcasting, one-touch key number information is broadcast together with video and audio in order to allow one-touch input of numeric keys such as a remote control to select a channel. This is part of the information constituting the channel number, and may be duplicated in broadcasting from a plurality of broadcasting stations like the channel number.

In Patent Literature 1, for broadcast channels to which branch numbers are assigned by overlapping one-touch key numbers, broadcast channels whose branch numbers are not default values (outside broadcast channels) are not yet associated with any broadcast channel. A method for assigning key numbers is proposed.
JP 2004-363819 A

  In the invention of Patent Document 1, since a broadcast channel whose branch number is not default (broadcast channel outside the area) is automatically assigned to an unassigned one-touch key number, the user does not know which button is assigned. Therefore, it may be assigned to a one-touch key number that is not intended by the user, which reduces convenience.

  For this purpose, a method of displaying a list of receivable broadcasting stations and allowing the user to explicitly assign a one-touch key, such as an analog television, can be considered, but is complicated.

  The present invention has been made in view of these problems. In particular, in a plurality of broadcast channels with overlapping one-touch key numbers, the user can easily assign a one-touch key number to a broadcast channel. An object is to provide a broadcast receiving apparatus.

  In order to achieve the above object, a broadcast receiving apparatus according to a first aspect of the present invention selects a receiving means for receiving broadcast waves of a plurality of broadcast channels and a received broadcast wave of a plurality of broadcast channels. Station selection means, an instruction for selecting a broadcast channel in the channel selection means, an operation means constituted by at least one operation member, and according to the operation means being operated, by the channel selection means Control means for switching channel selection, at least one of the operation members is set so as to be capable of instructing channel selection of one or a plurality of broadcast channels, and at least one of the operation members is a plurality of broadcasts. If it is set so that channel selection can be instructed, the operation member assigned to a plurality of broadcast channels is operated, and the operation member assigned to the operation member is operated. The channel selection means is controlled so as to sequentially select the broadcast channels, and it is detected whether or not any of the plurality of broadcast channels assigned to the operation member can be assigned to other operation members of the operation means, and assigned. If possible, control is performed to display information indicating operation members that can be assigned.

  Further, the broadcast receiving apparatus according to the second invention is a receiving means for receiving broadcast waves of a plurality of broadcast channels, a tuning means for selecting any of the received broadcast waves of the plurality of broadcast channels, An operation unit configured to receive an instruction for selecting a broadcast channel in the channel selection unit, and a control unit configured to switch the channel selection by the channel selection unit in response to the operation unit being operated. , And at least one of the operation members is set to instruct selection of one or a plurality of broadcast channels, and the control means can instruct at least one of the operation members to select a plurality of broadcast channels. When the operation member to which a plurality of broadcast channels are assigned is operated, the plurality of broadcast channels assigned to the operation members are sequentially ordered. The channel selection unit is controlled to select a channel, and one of the plurality of operation members of the operation unit is operated as an operation member to which no broadcast channel is assigned. Control is performed to display that at least one of a plurality of assigned broadcast channels can be assigned.

  As described above, according to the present invention, it is possible to assign a desired one-touch key number to a desired broadcast channel with few operations by the user, and the operability is improved.

  Compared with Patent Document 1, a broadcast channel contrary to the user's intention is not assigned to the one-touch key number, which is highly convenient.

However, it is not limited to that.

1.2. Structure of data and table 1.2.1. Configuration of channel information table 200 held by channel information management unit 108 An example of the channel information table 200 held by the channel information management unit 108 is shown in FIG. In the present embodiment, the channel information table 200 is configured by channel information 300 of a plurality of broadcast channels that can be received by the mobile terminal device 100 of the present invention. Since the channel information 300 is obtained from SI information included in the digital broadcast signal sent on each broadcast channel, it can be acquired by receiving the digital broadcast signal.

  The channel information 300 for each broadcast channel includes a channel number, a one-touch key number, a branch number, and a broadcast station name.

  In the example of FIG. 2, the broadcast station name AAA TV indicates that the channel number is 011, the one-touch key number is 1, and the branch number is 0. The broadcast station BBB TV indicates that the channel number is 011, the one-touch key number is 1, This indicates that the branch number is 1, the broadcast station CCC TV indicates that the channel number is 011, the one touch key number is 1, and the branch number is 2, and the broadcast station DDD TV indicates that the channel number is 041 and the one touch key number is 4. Indicates no branch number.

  When the channel number and the one-touch key number are the same, each branch number is uniquely assigned a value of 0 or more to distinguish them. Branch numbers are not assigned to DDD TV, EEE TV, FFF TV, and GGG TV without duplication.

2. Operation 2.1. Description of Channel Information Table Creation Operation of Portable Terminal Device 100 of the Present Invention Hereinafter, a channel information table creation operation by the portable terminal device 100 of the present invention will be described with reference to FIG.

  FIG. 3 shows that in the mobile terminal device 100 of the present invention, the user selects a channel after calling a function for searching for a broadcast channel that can be received by the mobile terminal device 100 by remote control operation (hereinafter referred to as a channel scan function). 5 is a flowchart showing a flow of operations for detecting a receivable broadcast channel and creating a channel information table.

  The user input unit 102 receives a key input for calling the channel scan function, and instructs the channel selection control unit 106 to execute the channel scan function (S1001).

  The channel selection control unit 106 receives the channel scan function execution instruction, and instructs the tuner 101 and the demultiplexer 103 to select the channel to all broadcast frequencies, receive the digital broadcast signal, and separate the SI information (S1002).

  The tuner 101 and the demultiplexer 103 receive the digital broadcast signal, separate the SI information, and output it to the channel information management unit 108 (S1003).

  The channel information management unit 108 extracts channel information from the received SI information (S1004). Whether there is channel information having the same number as the one-touch key number of the channel information is searched from the channel information table (S1005).

  If channel information having the same one-touch key number does not exist in the channel information table, the acquired channel information is added to the channel information table as it is (S1006). At this time, branch numbers are not assigned.

  When channel information having the same one-touch key number exists in the channel information table, a default branch number 0 is assigned to the acquired channel information and added to the channel information table, and the channel information table has the same one-touch key number. 1 is added to the branch numbers of all other channel information (S1007).

  If channel selection for all broadcast frequencies has not been completed, the channel selection control unit 106 returns to S1002 to instruct channel selection to the next broadcast frequency (S1008). When channel selection for all broadcast frequencies is completed, the channel scan function is terminated.

2.2. Description of Flow of Channel Selection Operation of Portable Terminal Device 100 of the Present Invention Hereinafter, the flow of channel selection operation and one-touch key number assignment operation of the portable terminal device 100 of the present invention will be described using FIG.

  FIG. 4 shows channel information corresponding to the content of a user's remote control input (one-touch key input) in the portable terminal device 100 of the present invention, and selects a corresponding broadcast channel according to the information and outputs video and audio. 4 is a flowchart showing a rough flow of an operation for assigning to channel information when the inputted one-touch key number is not assigned to channel information.

  If there is a one-touch key number input in the user input unit 102, it is output to the channel selection control unit 106 (S2001).

  The channel selection control unit 106 passes the one-touch key number to be selected, the one-touch key number being currently selected, and the branch number received from the user input unit 102 to the channel information management unit 108 (S2002).

  When channel information corresponding to the one-touch key number exists (S2003), the channel information management unit 108 compares the one-touch key number to be selected and the one-touch key number being selected, received from the channel selection control unit 106. (S2004).

  If the two one-touch key numbers are different, the channel information management unit 108 extracts channel information corresponding to the one-touch key number to be selected from the channel information table and outputs the channel information to the channel selection control unit 106 (S2005). When there are a plurality of channel information corresponding to the one-touch key number (that is, there is a branch number), the channel information of the default branch number 0 is extracted.

  When both one-touch key numbers are the same, the channel information management unit 108 extracts the channel information of the one-touch key number and the branch number next to the currently selected branch number from the channel information table 200, and performs channel selection control. The data is output to the unit 106 (S2006). The next branch number is obtained by adding 1 to the currently selected branch number. When the maximum branch number of the channel information of the one-touch key number existing in the channel information table 200 is exceeded, it is set to 0. return.

  The channel selection control unit 106 outputs the channel information acquired from the channel information management unit 108 to the demultiplexer 103, and instructs the separation of video and audio and SI information necessary for channel selection. Thus, the video / audio data separated by the demultiplexer 103 is decoded and output by the AV decoder 104 and the output unit 105, and the SI information is output to the channel information management unit (S2007). Then, the process returns to S2001 to wait for key input again.

  If there is no channel information to which the one-touch key number is assigned (S2003), the assignable channel detection unit 107 searches the channel information management unit 108 for channel information to which a branch number other than the default number 0 is assigned. An instruction is given (S2008).

  If there is no channel information to which a branch number other than 0 is assigned, the channel information management unit 108 displays that the one-touch key number is not assigned, and returns to S2001 without selecting a channel (S2009).

  When the channel information exists, the assignable channel detection unit 107 passes the channel information and the one-touch key number to the assignable channel list selection unit 109, and the assignable channel list selection unit 109 receives the received channel information with the branch number. They are displayed in order from the youngest, and are selected by the user (S2010).

  If no channel is selected after waiting for key input (S2011), a message indicating that the one-touch key number is not assigned is displayed, and the process returns to S2001 without selecting a channel (S2009).

  When a channel is selected by the user, the assignable channel list selection unit 109 passes the channel information selected by the user and the one-touch key number to the channel information management unit 108, and the channel information management unit 108 selects the one-touch key of the channel information. The number is replaced with the one-touch key number and re-registered in the channel information table 200 (S2012). Then, the process proceeds to S2007 in order to select the broadcast channel of the channel information.

First, the channel selection operation will be described with reference to the channel information table 200 shown in FIG.
In FIG. 2, there are three channels with the one-touch key number 1, each assigned a branch number. First, when the one-touch key number 1 is pressed, the channel (channel number 011, broadcast station name AAA TV) having the default branch number 0 is selected. In this state, when the one-touch key number 1 is pressed again, the BBB TV with the branch number 1 is further pressed. When the key is pressed further, the CCC TV with the branch number 2 is further pressed. Since there is no larger branch number, the default branch number 0 is returned to AAA television, and the following is repeated. When a channel is once selected by another one-touch key number and then the one-touch key number is input again, the channel with the default branch number 0 is selected again.

  Next, as an example of an operation for assigning a one-touch key number, a case where an unassigned one-touch key number 3 is pressed in the state of the channel information table of FIG. 5 will be described.

  Since the one-touch key number 3 does not exist in the channel information table 200, the allocatable channel list selection unit 109 acquires channel information to which a branch number other than the default value 0 is assigned from the channel information management unit 108. In this case, the broadcast channel with channel number 011, one-touch key number 1, branch number 1 (broadcast station name BBB TV), and the broadcast channel with channel number 011, one-touch key number 1, branch number 2 (broadcast station name CCC TV) Is applicable.

  Since the assignable channel list selection unit 109 displays the two channel information in order from the smallest branch number, the assignable channel list selection unit 109 displays the assignable channel list screen in the order of the branch number 1 BBB television and the branch number 2 CCC television. To do. An example of the screen is shown in FIG.

  When the user selects the CCC television with branch number 2 on the assignable channel list screen of FIG. 6, the one-touch key number of the channel information is assigned to 3.

  Therefore, the channel information table held by the channel information management unit 108 after assigning the one-touch key number to the channel information of the CCC television is as shown in FIG. Thereafter, when the one-touch key number 3 is input, the CCC television of the branch number 2 is selected.

  As described above, the mobile terminal device 100 according to the first embodiment is assigned to the antenna, the tuner 101, the user input unit 102, the channel selection control unit 106, the assignable channel detection unit 107, and the channel information management unit 108. And a configuration including a possible channel list selection unit 109. The configuration including the channel selection control unit 106, the assignable channel detection unit 107, the channel information management unit 108, and the assignable channel list selection unit 109 is an example of the control means of the present invention. The antenna receives broadcast waves of a plurality of broadcast channels. The tuner 101 selects one of the received broadcast waves of a plurality of broadcast channels. The user input unit 102 receives an instruction for selecting a broadcast channel in the tuner 101, and includes at least one numeric key. The control means switches the channel selection by the tuner 101 in response to the user input unit 102 being operated. At least one of the numeric keys is set so as to instruct channel selection of one or a plurality of broadcast channels. When at least one of the numeric keys is set so that channel selection of a plurality of broadcast channels can be instructed, the control means changes the numeric key in response to the operation of the numeric key to which the plurality of broadcast channels are assigned. Whether the tuner 101 is controlled to sequentially select a plurality of assigned broadcast channels and whether any of the plurality of broadcast channels assigned to the numeric keys can be assigned to other numeric keys of the user input unit 102 If it can be assigned, information indicating the assignable numeric keys is displayed.

  In addition, as shown in this Embodiment 1, a control means may receive selection by a user about whether any one of several broadcast channels is allocated to another number key.

  In addition, as shown in the first embodiment of the present invention, the control means assigns the broadcast channel currently being received by the antenna to the numeric key in response to the operation of the numeric key displayed as assignable. You may control so.

  Further, as shown in the first embodiment, the control means controls to assign the broadcast channel currently received by the antenna to the numeric key in response to the operation of the numeric key to which a plurality of broadcast channels are assigned. May be.

  In addition, as shown in the first embodiment, the control means is configured such that, when at least one of the numeric keys is set so as to instruct the selection of a plurality of broadcast channels, a plurality of broadcasts assigned to the numeric keys. By assigning a different branch number to each of the channels, tuning of the tuner 101 by operating a numeric key to which a plurality of broadcast channels are assigned may be controlled.

  Further, as shown in the first embodiment, the control means may perform control so that the assignable broadcast channels are displayed in ascending order of the branch numbers of the respective broadcast channels.

  In this embodiment, when a one-touch key number that is not assigned to a broadcast channel in the channel information table 200 is input, an assignable channel list screen is displayed, a channel is selected, and a one-touch key is assigned to the channel. Although the number is assigned, even when the one-touch key number already assigned to one of the broadcast channels is pressed, the one-touch key number may be reassigned on the assignable channel list screen.

  In order to distinguish one-touch key number input from normal channel selection, the one-touch key numbers may be reassigned on the assignable channel list screen only when long-pressed or double-clicked.

  In the assignable channel list, channels having the default branch number 0 or channels having no branch number are treated as candidates for assignment, and when they are selected, one-touch key number assignment of those channel information is performed. May be changed. In this case, since the one touch key number to which the channel information was originally assigned becomes unassigned, the channel information to be assigned to the one touch key number is further selected from the assignable channel list, and the one touch key is assigned to the channel. A number may be assigned.

  Note that the list of allocatable channels may be arranged in the order of the number of channel selections, or may be arranged in the order of the channels selected most recently.

(Embodiment 2)
1. Configuration Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.

1.2. Configuration of Mobile Terminal Device 100 With respect to the second embodiment of the present invention, only differences from the first embodiment will be described.
The second embodiment is the same as the configuration of the mobile terminal device 100 as an example of the first embodiment, and is omitted because it is shown in FIG. Note that the channel information table 200 held by the channel information management unit 108 is also the same as that in the first embodiment, and thus the description thereof is omitted. Hereinafter, only the portions of each processing unit that are different in function from the first embodiment will be described. Note that the following differences may be added to the first embodiment for implementation.

  The channel selection control unit 106 according to the second embodiment receives remote controller input information (one-touch key number) from the user input unit 102, acquires channel information corresponding to the input content from the channel information management unit 108, Therefore, the audio / video and SI information to be received and separated are designated to the tuner 101 and the demultiplexer 103. The channel selection control unit 106 holds the channel number, one-touch key number, and branch number of the channel information currently being selected. Further, the channel selection control unit 106 assigns an allocatable channel detection unit when a branch number other than the default value 0 is assigned to the currently selected channel and the one-touch key number is not allocated to any broadcast channel. The channel information and the one-touch key number are output to 107.

  The allocatable channel detection unit 107 receives from the channel selection control unit 106 an instruction to detect a broadcast channel that can be allocated to a one-touch key number to which a broadcast channel has not been allocated, and sends a one-touch key number to the channel information management unit 108. And the channel information is output, and the one-touch key number is assigned to the channel information.

2. Operation Although the operation of the mobile terminal device 100 of the present invention will be described, the channel information table creation operation and the channel selection operation are the same as those in the first embodiment, and thus description thereof will be omitted.

2.1. Description of the One-Touch Key Number Assignment Operation of the Mobile Terminal Device 100 of the Present Invention Hereinafter, the one-touch key number assignment operation by the mobile terminal device 100 according to the second embodiment of the present invention will be described with reference to the drawings.

  FIG. 8 shows the channel selection operation of this apparatus by one-touch key number input and channel selection control when an unassigned one-touch key number is input in a state where a broadcast channel whose branch number is not the default value 0 is selected. 6 is a flowchart showing a flow of operations for assigning the broadcast channel to the one-touch key number in the unit 106, the assignable channel detection unit 107, and the channel information management unit 108.

  If there is a one-touch key number input in the user input unit 102, it is output to the channel selection control unit 106 (S3001).

  The channel selection control unit 106 passes the one-touch key number to be selected, the one-touch key number being currently selected, and the branch number received from the user input unit 102 to the channel information management unit 108 (S3002).

  When there is channel information corresponding to the one-touch key number (S3003), the channel information management unit 108 compares the one-touch key number to be selected and the one-touch key number being selected, received from the channel selection control unit 106. (S3004).

  If the two one-touch key numbers are different, the channel information management unit 108 extracts channel information corresponding to the one-touch key number to be selected from the channel information table and outputs the channel information to the channel selection control unit 106 (S3005). When there are a plurality of channel information corresponding to the one-touch key number (that is, there is a branch number), the channel information of the default branch number 0 is extracted.

  When both one-touch key numbers are the same, the channel information management unit 108 extracts the channel information of the one-touch key number and the branch number next to the currently selected branch number from the channel information table 200, and performs channel selection control. The data is output to the unit 106 (S3006). The next branch number is obtained by adding 1 to the currently selected branch number. When the maximum branch number of the channel information of the one-touch key number existing in the channel information table 200 is exceeded, it is set to 0. return.

  The channel selection control unit 106 outputs the channel information acquired from the channel information management unit 108 to the demultiplexer 103, and instructs the separation of video and audio and SI information necessary for channel selection. As a result, the video / audio data separated by the demultiplexer 103 is decoded and output by the AV decoder 104 and the output unit 105, and the SI information is output to the channel information management unit (S3007). Then, the process returns to S3001 to wait for key input again.

  If there is no channel information to which the one-touch key number is assigned, the channel selection control unit 106 confirms the branch number of the channel information currently being selected (S3008).

  If no branch number is assigned to the channel information of the currently selected broadcast channel, or the default branch number is 0, the channel cannot be selected because the one-touch key number is not assigned to the broadcast channel. To the user (S3009), and the process returns to S3001. In this case, a new channel selection process is not performed.

  When a branch number other than the default value 0 is assigned to the channel information of the currently selected broadcast channel, the channel selection control unit 106 notifies the channel information currently being selected and the one-touch key to the assignable channel detection unit 107. The assigned channel detection unit 107 changes the one-touch key number information of the currently selected channel information to the received one-touch key number, and passes the number to the channel information table 200. (S3010), and the process returns to S3001. In this case, a new channel selection process is not performed.

  As an operation example of the one-touch key number assignment from S3008, in the state of the channel information table 200 of FIG. 9, the channel number 011 and the branch number 2 broadcast channel (broadcast station name CCC TV) are not selected during channel selection. A case where the one-touch key number 3 is pressed will be described.

  Since the one-touch key number 3 does not exist in the channel information table 200 and the channel being selected is branch number 2 and is not the default value 0, the channel selection control unit 106 and the assignable channel detection unit 107 have channel numbers 011 and branch numbers. One touch key number 3 is assigned to two broadcast channels (broadcast station name CCC TV). Therefore, FIG. 10 shows a channel information table 200 that is finally held by the channel information management unit 108 in this case. Thereafter, when the one-touch key number 3 is pressed, the broadcast channel (broadcast station name: CCC TV) having the channel number 011 and the branch number 2 is selected.

The antenna receives broadcast waves of a plurality of broadcast channels. The tuner 101 selects one of the received broadcast waves of a plurality of broadcast channels. The user input unit 102 receives an instruction for selecting a broadcast channel in the tuner 101, and includes at least one numeric key. The control means switches the channel selection by the tuner 101 in response to the user input unit 102 being operated. At least one of the numeric keys is set so as to instruct channel selection of one or a plurality of broadcast channels. When at least one of the numeric keys is set so that channel selection of a plurality of broadcast channels can be instructed, the control means changes the numeric key in response to the operation of the numeric key to which the plurality of broadcast channels are assigned. The tuner 101 is controlled to sequentially select a plurality of assigned broadcast channels, and in response to an operation of a number key to which no broadcast channel is assigned among a plurality of number keys of the user input unit 102. The number key is controlled to display that at least one of a plurality of broadcast channels assigned to one number key can be assigned.

  As shown in the second embodiment, the control means accepts a selection by the user as to whether or not to assign any of the plurality of broadcast channels to a numeric key to which no broadcast channel is assigned. Also good.

  In addition, as in the first embodiment, the control means controls to allocate the broadcast channel currently received by the antenna to the numeric key in response to the operation of the numeric key displayed as being assignable. May be.

  Further, as in the first embodiment, the control means controls to assign the broadcast channel currently received by the antenna to the numeric key in response to the operation of the numeric key to which a plurality of broadcast channels are assigned. May be.

  Similarly to the first embodiment, when at least one of the numeric keys is set to instruct the selection of a plurality of broadcast channels, the control means is configured to use a plurality of broadcast channels assigned to the numeric keys. By assigning a different branch number to each of these, the tuning of the tuner 101 may be controlled by operating a numeric key to which a plurality of broadcast channels are assigned.

  Further, as in the first embodiment, the control means may perform control so that the assignable broadcast channels are displayed in ascending order of the branch numbers of the respective broadcast channels.

  In this embodiment, when a one-touch key number button to which a broadcast channel is not assigned is pressed, the one-touch key number is assigned to the selected broadcast channel, but the already-assigned one-touch key number is pressed. In this case, the assignment of the one-touch key number may be changed, and the one-touch key may be changed even when the branch number of the broadcast channel being selected is not the default or the channel to which the branch number is not assigned. A key number may be assigned.

  A screen for confirming to the user whether or not to assign the one-touch key number to the selected broadcast channel may be displayed and assigned only when the user permits.

  As a condition for assigning the one-touch key number, in order to distinguish the method of pressing the one-touch key number from normal channel selection, a long press or double click may be used.

  The antenna is an example of the receiving means of the present invention. The tuner 101 is an example of a channel selection unit of the present invention. The user input unit 102 is an example of an operation unit of the present invention. The numeric key is an example of the operation member of the present invention.

  The broadcast receiving apparatus according to the present invention is an apparatus that receives and displays a broadcast, and can be applied to all apparatuses having a function of selecting a plurality of broadcast channels having the same channel number and one touch key number. For example, the present invention can be applied to a 1-segment digital television reception viewer, a mobile phone terminal with a digital broadcast reception function, a digital camera with a digital broadcast reception function, a car TV, a DVD with a digital broadcast reception function, a mobile terminal that can be connected to a network, and the like.
