Description

  The present invention relates to a display device, and more particularly to a display device having reservation functions such as a recording reservation, a viewing reservation, and a reproduction reservation.

  Some display devices such as a television device having a broadcast signal receiving function can make viewing reservations by a user. In the viewing reservation function, viewing of a broadcast program desired by the user can be reserved in the display device in advance, and when the viewing reserved time arrives, the display device selects the program reserved for viewing. It is displayed on the display screen.

  Some display devices such as a television device can make a recording reservation for a recording device connected to the display device or a recording medium such as a recording module built in the display device. In the recording reservation function, recording of a broadcast program desired by the user can be reserved in the display device in advance, and when the recording reservation time arrives in the display device, the recording medium of a predetermined recording device or recording module Is controlled to record the selected program.

  Similarly, some display devices have a playback reservation function for playing back desired recorded content at a time desired by the user. In the playback reservation function, playback of recorded content such as a broadcast program desired by the user can be reserved in the display device in advance, and the display device is designated when the time reserved for playback comes. Control is performed to play back the specified content recorded on the recording medium of the recording device or the recording module and display it on the display screen of the display device.

Regarding a display device having a reservation recording function, for example, Patent Document 1 discloses a digital broadcast receiving device that performs a display that does not give a sense of incongruity to a user even when a reservation recording process starts during multi-screen display. Yes.
This digital broadcast receiving apparatus determines whether or not the display unit is currently displaying two or more screens when, for example, two minutes before the reservation start, when an instruction related to reserved recording is received from the remote control device. If two or more screens are being displayed, the screen of the program reserved for recording is removed before the scheduled recording start time, that is, one screen that is not selected as a reserved channel is left, Hide one screen. Next, at the reservation start time, reservation recording is started. At this time, a display for notifying the user that reservation recording has been started is performed.
JP 2008-35179 A

  As described above, in a display device having a viewing reservation function, a broadcast program that has been reserved for viewing by the user in advance is displayed on the display screen when the reserved time arrives. In such a case, when the viewing reservation time arrives when another user who has not set viewing reservation is viewing the display screen, the screen is switched unexpectedly and the viewing reservation is made without expectation by the currently viewing user. Broadcast program display starts. In this case, the user who has been viewing is confused by unexpected switching of the display screen.

  In addition, when another user who has not set viewing reservation as described above is viewing the screen, and the screen is switched according to the viewing reservation, the user currently viewing performs an operation of returning the display screen to the original state. Sometimes. In such a case, the user who actually set the viewing reservation cannot listen to the broadcast program reserved by himself / herself. Alternatively, it may be assumed that the user who has set the viewing reservation cannot audition the desired program when another user performs an operation to cancel the viewing reservation while the viewing reservation is set on the display device. The In addition, when the viewing reservation is set, the user who has set the viewing reservation cannot view the reserved broadcast program or the like unless it is in front of the display device when the viewing reservation time arrives. There is also.

For example, it can be assumed that when playback of content reserved for playback starts, the screen is switched by another user, or the playback reservation is canceled by another user. In addition, the user needs to be in front of the screen when starting playback of the content reserved for playback.

  In the case of recording reservation, there is a request that the user wants to confirm whether recording of a pavement program or the like reserved for recording has been started reliably. For example, when a recording reservation is set in the display device, and then the recording reservation time comes and recording starts, the screen during recording is not displayed on the display device in the conventional display device. At this time, for example, an OSD (On Screen Display) such as “Recording” may be displayed, but in this case also, the user cannot confirm the actual recording screen.

  In order to deal with such a problem, Patent Document 1 discloses a method in which one screen is replaced and displayed when a reservation is made during multi-screen display during viewing reservation as described above. However, since the display screen is replaced during single-screen display or multi-screen display, there is a problem that the current viewing program is interrupted.

  The present invention has been made in view of the above circumstances, and is a reservation target without affecting the viewing of a currently viewed program or the like in a display device having a viewing reservation, playback reservation, or recording reservation function. It is an object of the present invention to provide a display device and a display system that can surely grasp the status of viewing, playback, and recording of a program.

  Further, the display device receives a timer 13 for elapse of time, a ROM 15 for storing programs and data, a RAM 16 for developing programs and processing them at high speed, a control unit (CPU) 14 for controlling the whole, and a remote control signal. A remote control light receiving unit 17, an input / output I / F 18, an OSD display unit 19 and the like are provided.

  The input / output I / F 18 is connected to an external device such as a recording device, and inputs / outputs video / audio streams and control signals to / from the external device. The video / audio stream can be transmitted by an I / F based on a standard such as HDMI (High-Definition Multimedia Interface) or IEEE1394. In addition, an I / F to which a D terminal, an S terminal, a pin terminal, or the like is applied may be used. A control command based on the HDMI standard or the IEEE 1394 standard can be used as a control signal for controlling an external device.

The OSD display unit 19 generates an OSD signal to be displayed on the display unit 9 according to control by the control unit 14 and outputs the OSD signal to the screen composition unit 8. The screen synthesizing unit 8 synthesizes the OSD signal with the decoded video signal output from the front ends 2 and 5 and outputs it to the display unit 9. Further, the OSD display unit 19 can generate and output an OSD signal to be displayed on the display unit 19 based on the OSD information specified in the data signal included in the received digital broadcast signal.
The timer 13 passes time. The control unit 14 monitors the timer 13 and determines the arrival of the viewing reservation time, recording reservation time, and reproduction reservation time set in the display device. Further, the remote control light receiving unit 17 receives an operation signal from a remote control that is an operation input unit of the display device, and outputs the operation signal to the control unit 14.

  The control unit 14 in FIG. 1 includes a display control unit according to the present invention that controls display on the display unit, a recording control unit according to the present invention that performs recording control of a recording reservation target, and a temporary storage unit that temporarily stores a viewing reservation target. The function of the temporary storage control unit is realized. The temporary storage means of the present invention is realized by the RAM 16, a recording module (not shown) or a recording medium provided in an external connection device.

With the configuration described above, the display device can simultaneously display broadcast programs selected by the two tuners on one screen.
As described above, the configuration example shown in FIG. 1 shows a display device configured as a television with two tuners, but the control according to the present invention is performed even with a television with one tuner. Can do. In this case, the circuit including one front end is omitted from the circuit including the two systems of front ends shown in FIG. For other functions, the same configuration as that of FIG. 1 can be applied. Further, the display device may be configured to have three or more front ends.

  In the above display device, a recording module (not shown) having a recording / playback function can be incorporated. In this case, the recording module is mounted with a recording medium such as a BD (Blu-ray Disc) or DVD, a recording / reproducing drive, a fixed recording medium drive such as an HD (Hard Disk), or a USB ( (Universal Serial Bus) A module that performs recording / playback on a memory or various memory cards. These recording modules may be configured to include a control unit such as a CPU separately from the control unit 14 of the display device, and to decode the recorded content by the control unit. In this case, even a recording module built in the display device can be controlled as one of external inputs to the display device.

  For example, in the case of playing back from recorded content recorded on the recording medium of the recording module, video data and additional data can be output as video after the content data recorded on the recording medium is decoded by the decoder of the recording module The data is converted into a format and output to the display unit 9, and the audio data is converted into a format that can be output as audio and output to the audio output units 11 and 12 in synchronization with the video.

Record on the module recording medium.
Alternatively, when recording received digital broadcast programs or externally recorded content that has been rate converted, video data that has been compression-encoded by the transcoder of the recording module is inversely quantized, and the quantization step is changed. Processing such as requantization can be performed.

(Example of processing related to viewing reservation)
FIG. 2 is a diagram for explaining an example of a display screen at the time of viewing reservation in the embodiment of the display device according to the present invention.
As described above, the viewing reservation function is a function capable of making a reservation for viewing a desired broadcast program in advance, and the display device selects the program reserved for viewing and displays it on the display screen when the viewing reservation time arrives. Control to be performed. Here, in one embodiment according to the present invention, when the viewing reservation time arrives, a second screen different from the currently displayed screen is displayed, and the viewing reservation is reserved for the second screen. Display the display screen.

FIG. 2A shows a state where a broadcast program is displayed (viewed) on a display device having a broadcast receiving function. Here, it is assumed that a program with a service ID “103” of BS (broadcasting satellite) broadcasting, for example, is displayed on the full screen 101 on the display screen 100 of the display device. For the sake of explanation, the broadcast type and the service ID are described simply as “BS103” below.
Here, it is assumed that a specific broadcast program is reserved in advance at a specific time by the viewing reservation function of the display device. When the reservation time of the broadcast program reserved for viewing has arrived, the program reserved for viewing is displayed. In this embodiment, when the reservation time of the program reserved for viewing has arrived, as shown in FIG. As described above, the screen 100 is switched to the multi-screen display.

  Here, the currently displayed program “BS 103” is displayed on the first screen 102, and the program reserved for viewing (for example, “BS 141”) is displayed on the second screen 103. In this example, the second screen 103 that displays a program reserved for viewing is smaller than the first screen 102. At this time, as the output sound from the display device, the sound of “BS103” displayed so far is output as it is.

  The screen 100 further displays a message screen 104 for notifying that a program reserved for viewing is displayed. As shown in FIG. 2C, the message screen 104 displays a GUI including a message “Reservation is being executed. Do you want to move to the reservation 1 screen?” The user can select whether to move to the display.

When the user operates the determination key of the remote controller in the state of FIG. 2B, the screen 100 can be shifted to a screen 100 as shown in FIG. Here, the program displayed on the second screen 103 by the viewing reservation is switched by the user's decision key operation and displayed on the screen 100 as one screen. Here, the program on the first screen ("BS103") that was displayed before the start of displaying the reserved viewing program is not displayed. Further, on the screen 100 of FIG. 2D, a message 105 “viewing reservation in progress” indicating that the program reserved for viewing is currently displayed is displayed. This message 105 can be displayed by the OSD.
The user can return to the screen of FIG. 2B by operating the return key of the remote control on the screen of FIG.

When the start time of the program reserved for viewing has arrived, the second screen 103 and the message screen 104 are displayed even if there is no other program currently being viewed on the display device, so that the program reserved for viewing is displayed. It becomes clear that has started. In this case, the program reserved for viewing may be displayed on one screen. At this time, it is not necessary to display the message screen 104 including the GUI for switching to the single screen display, but it is preferable to display the OSD indicating that the viewing reservation program has started.
Also, a GUI that allows switching to recording reservation may be displayed on the viewing reservation message screen 104.

  When a program reserved for viewing is displayed on a multi-screen, the screen displayed as the first screen 102 may be not only a broadcast program being received but also an image of content input externally. For example, when a start time of a program reserved for viewing has come while a stream output from a recording / playback apparatus (such as a BD player) connected to the display apparatus is being played back on the display apparatus, the stream output from the recording / playback apparatus Can be displayed on the first screen 102, and the program reserved for viewing can be displayed on the second screen 103. The same applies to the case where playback is performed using a recording module built in the display device.

  When making a reservation for viewing a broadcast program, as shown in FIG. 1, a display device having two front ends can display 2 even if another program is displayed at the start time of the program reserved for viewing. Two front ends can display two programs simultaneously.

  In addition, in a display device having only one front end, when a program reserved for viewing is started when a broadcast program is previewed using the front end, it cannot be displayed on two screens. However, for example, when a recorded program output from an external device (such as a BD recorder) or a built-in recording module is being played back on the display device, only one front end is used to display a program reserved for viewing. Therefore, the two-screen display as described above can be performed. Alternatively, if an external device such as a recording / playback device with a tuner or an STB (Set Top Box) is connected to the display device, the display device controls the external device and reserves the viewing program. At the start of the program, the program may be selected by the tuner of the external device and output to the display device. Thereby, the program reserved for viewing can be displayed on the second screen 103.

  In this way, when the start time of a program reserved for viewing has arrived, the program reserved for viewing is displayed on the second screen 103, so that the currently viewed program is not suddenly interrupted. The user can know that has started. Further, by displaying the message screen 104 including the GUI for switching the program reserved for viewing to the single screen display together with the second screen 103, the user can switch to the single screen display at an arbitrary timing. For example, the user can perform an operation such as confirming that the first commercial of a program reserved for viewing is finished and switching to a one-screen display.

  Further, when a program reserved for viewing is displayed on the second screen 103, recording of the program reserved for viewing may be started. In this case, the recording destination is determined in advance, and for example, a built-in recording module of the display device or an externally connected recording device can be used. Further, since the recording in this case is temporary recording, the program reserved for viewing may be recorded in a temporary buffer such as a RAM provided in the display device.

  The recording of the program reserved for viewing may be continued until there is a user operation for instructing the end of recording in this case, but after the program reserved for viewing is displayed on the second screen 103, the user operation Thus, the recording may be automatically ended when the second screen 103 is switched to the single screen display.

  Further, when the program reserved for viewing on the second screen 103 is switched to a single screen display, playback may be started from the beginning of the recorded program and displayed on a single screen. In this case, a process of performing reproduction from the oldest in time is executed while storing the newly received stream in the temporary buffer. At this time, the portion of the stream that has been reproduced may be sequentially erased from the temporary buffer, or may be sequentially erased after a certain time has elapsed after the reproduction. Alternatively, if the second screen 103 is displayed at the same time as the program reserved for viewing and the second screen is switched to full screen display, the stream data recorded in the temporary buffer is deleted. It may be. A predetermined threshold can be used to determine whether or not the time at this time is short.

  FIG. 3 is a view for explaining another display screen example at the time of viewing reservation in the embodiment of the display device according to the present invention. In the example of FIG. 3, when the viewing reservation time arrives while viewing a broadcast program by multi-screen display, another screen different from the currently displayed multi-screen is displayed. The display screen of the program reserved for viewing is displayed on the screen.

FIG. 3A shows a state where a broadcast program is displayed (viewed) on a display device having a broadcast receiving function. Here, it is assumed that, for example, “BS103” and “BS181” are displayed on the display screen 100 of the display device on the first screen 111 and the second screen 112, respectively. In this case, the output sound is the sound of one of the programs (for example, “BS103”).
Here, when a reserved broadcast program is reserved in advance so that a specific broadcast program can be viewed at a specific time and the reserved time of the broadcast program reserved for viewing has arrived, as shown in FIG. The displayed program is displayed.

At this time, in this embodiment, when the reservation time of the program reserved for viewing comes, the display screens (the first screen 111 and the second screen 112) of the currently displayed programs “BS103” and “BS181” are viewed. Two screens 111 and 112 which are smaller than the display screen before the start of the reserved program and are displayed on the left and right are displayed side by side in the vertical direction.
Then, the program reserved for viewing (for example, “BS 141”) is displayed on the third screen 113. In this example, the third screen 113 displaying the program reserved for viewing is smaller than the first screen 111 and the second screen 112. At this time, as the output sound from the display device, the sound of “BS103” displayed so far is output as it is.

  3B further displays a message screen 114 for notifying that a program reserved for viewing is displayed. As shown in FIG. 4C, this message screen 114 displays a GUI including a message “A viewing reservation is being executed. Do you want to move to the reservation 1 screen?” And one screen of the program reserved for viewing. The user selects whether to move to the display.

  When the user operates the determination key of the remote controller in the state of FIG. 3B, the screen can be shifted to a screen 100 as shown in FIG. Here, the program displayed on the third screen 113 by the viewing reservation is switched by the user's decision key operation and displayed on the screen 100 as one screen. Here, the program of the first screen 111 ("BS103") and the program of the second screen ("BS181") displayed before the start of the viewing reservation program display is not displayed. In addition, on the screen 100 in FIG. 3D, a message 115 “viewing reservation in progress” indicating that the program reserved for viewing is currently displayed is displayed by the OSD. In addition, the user can return to the screen of FIG. 3B by operating the return key of the remote controller on the screen of FIG.

When three such screens are displayed at the same time and a broadcast program is displayed on all screens, three front ends are required. In a display device with two CFCs and an end, if the screen output from an external device or recording module is displayed on one screen during two-screen display, use the remaining front end for viewing The third screen 113 of the reserved program can be displayed.
When an external device with a tuner is connected and controllable, the program reserved for viewing may be selected by the tuner of the external device, output to the display device, and displayed on the third screen 113. it can.

  FIG. 4 is a flowchart for explaining an example of processing at the time of viewing reservation of the display device according to the present invention. When the display of the program reserved for viewing is started, the display device determines whether or not it is currently viewing (step S1). Viewing means a state in which a broadcast program is selected and displayed on the display screen, or a content input from an external device, a content recorded in a built-in module, or the like is displayed on the display screen.

  If the display device is currently being viewed, the viewing screen and the viewing reservation screen are scaled and displayed on one screen (step S2). That is, the scaled viewing screen and viewing reservation screen are displayed in two on one screen of the display unit. In addition, when the viewing screen is displayed in two or more multi-screens, the multi-viewing viewing screen and the viewing reservation screen are further scaled and displayed in one screen.

Then, a GUI for switching the viewing screen to single screen display is displayed (step S3). Here, a GUI including a message for confirming to the user whether or not to display the currently viewed screen that has been scaled and displayed on multiple screens is displayed.
Next, it is determined whether or not the operation for switching to the one screen during viewing is executed (step S4). When the operation for switching to one screen is performed, the viewing reservation screen is displayed on one screen. (Step S5), the switching to the reservation screen is terminated.

  On the other hand, if not viewing at step S1, the reserved viewing program is displayed on one screen (step S6). In this case, since there is no program currently being viewed, the reserved viewing program can be displayed on the entire screen.

FIG. 5 is a flowchart for explaining another example of processing at the time of viewing reservation of the display device according to the present invention.
When the display of the program reserved for viewing is started, the display device starts recording the program reserved for viewing (step S11). The recording destination is a recording medium of an externally connected recording device or a recording module with a built-in display device.

  Then, the display device determines whether or not it is viewing (step S12). Viewing means a state in which a broadcast program is selected and displayed on the display screen, or a content input from an external device, a content recorded in a built-in module, or the like is displayed on the display screen.

  If the display device is currently being viewed, the viewing screen and the viewing reservation screen are scaled and displayed on one screen (step S13). That is, the scaled viewing screen and viewing reservation screen are displayed in two on one screen of the display unit. In addition, when the viewing screen is displayed in two or more multi-screens, the multi-viewing viewing screen and the viewing reservation screen are further scaled and displayed in one screen.

Then, a GUI for switching the viewing screen to single-screen display is displayed (step S14). Here, a GUI including a message for confirming to the user whether or not to display the currently viewed screen that has been scaled and displayed on multiple screens is displayed.
Next, it is determined whether or not an operation for confirming the start of viewing reservation (that is, the viewing start of the program reserved for viewing) has been performed (step S15), and if the operation for confirming the start of viewing reservation has been performed, the viewing reservation screen is displayed. Displaying on one screen, the recording of the viewing reservation is stopped (step S16), and the switching to the reservation screen is ended.

  On the other hand, if viewing is not being performed in step S12, the viewing reservation program is displayed on one screen, and a GUI indicating the start of viewing reservation is displayed (step S17). In this case, since there is no program currently being viewed, the viewing reservation program can be displayed on the entire screen of one screen, and at the same time, a GUI indicating the viewing reservation is displayed by the OSD. Alternatively, the program reserved for viewing may be displayed on the second screen even if there is no program currently being viewed. Then, it is determined whether or not an operation confirming the start of viewing reservation (that is, the viewing start of the program reserved for viewing) has been performed (step S18), and if the operation confirming the start of viewing reservation is performed, the recording of the viewing reservation is performed. Is stopped (step S19), and the reservation start process is terminated.

(Example of processing related to recording reservation)
FIG. 6 is a diagram for explaining an example of a display screen at the time of recording reservation in the embodiment of the display device according to the present invention.
As described above, the recording reservation function is a function capable of making a reservation for recording a desired broadcast program in advance.

This is a control to make the video recording. The target recording medium in the recording reservation can be a recording medium installed in a recording module built in the display device or an external device connected to the display device.

In the embodiment of the recording reservation according to the present invention, when the recording reservation time arrives, a second screen different from the currently displayed screen is displayed, and the program reserved for recording on the second screen is displayed. Make it visible.
FIG. 6A shows a state in which a broadcast program is displayed (viewed) on a display device having a broadcast receiving function. Here, it is assumed that a program “BS103”, for example, is displayed on one screen 121 on the display screen 100 of the display device. Here, it is assumed that a specific broadcast program is reserved in advance for recording at a specific time by the recording reservation function. When the reserved time of the broadcast program reserved for recording comes, the program reserved for recording is displayed as shown in FIG. 6B. In this embodiment, the reserved time of the program reserved for recording is displayed. When it arrives, the screen 100 is switched to a multi-screen display.

  Here, the currently displayed program “BS103” is displayed on the first screen 122, and the program reserved for recording (for example, “BS141”) is displayed on the second screen 123. In this example, the second screen 123 displaying the program reserved for recording is a screen smaller than the first screen 122. At this time, as the output sound from the display device, the sound of “BS103” displayed so far is output as it is.

The screen 100 further displays a message screen 124 for notifying that a program reserved for recording is displayed. As shown in FIG. 6C, the message screen 124 includes a message “Recording reservation is being executed” in addition to information such as the service ID, date, title, and remaining amount of media of the content reserved for recording.
