  FIG. 1 is a diagram showing a schematic configuration of a television broadcast receiving apparatus 100 according to an embodiment of the present invention. Hereinafter, the television broadcast receiver 100 will be described with reference to FIG.

  As shown in FIG. 1, broadcast waves (broadcast signals) such as terrestrial waves and BS are input to the broadcast receiving module 102 via the antenna 101. The broadcast receiving module 102 includes a so-called tuner. In the broadcast receiving module 102, a broadcast signal of a desired channel is selected from a plurality of channel signals included in the broadcast signal. The broadcast signal selected by the broadcast receiving module 102 is supplied to the signal processing module 103. Note that the broadcast receiving module 102 in the present embodiment can simultaneously receive a plurality of video signals, and includes a so-called multiple tuner means.

  The signal processing module 103 performs demodulation processing, composite processing, and the like. The video signal and audio signal are selectively subjected to predetermined digital signal processing and then output to the subsequent video / audio output processing module 104.

  The video / audio output processing module 104 has a function of superimposing and outputting the OSD signal generated by the OSD (On Screen Display) generation module 105 on the digital video signal supplied from the signal processing module 103. The video / audio output processing module 104 selectively outputs the output video signal supplied from the signal processing module 103 and the OSD signal supplied from the OSD generation module 105, or both signals are displayed on the screen. They can also be combined and output to form half.

The video / audio output processing module 104 outputs a video signal to the video display unit 106 including a liquid crystal display panel, a plasma panel, and the like to display the video.
The video / audio output processing module 104 converts the input audio signal into an analog audio signal in a format that can be reproduced by the speaker 107, and then outputs the analog audio signal to the speaker 107 for audio reproduction.

Here, in the television broadcast receiving apparatus 100, all operations including the above-described various receiving operations are comprehensively controlled by the control module 108.
The control unit 108 includes a large number of ICs such as a CPU (Central Processing Unit). The television broadcast receiving apparatus 100 includes a ROM that stores a control program executed by the control module 108, a RAM that provides a work area to the CPU, a nonvolatile memory that stores various setting information and control information, and the like. Including a storage module 109. Note that video signal input information of at least one of the multiple screens described below is stored in the storage module 109.

  Further, the control unit 108 includes a screen division module (not shown) that divides the screen of the video display unit 106 into at least a first screen area and a second screen area. This means that the television broadcast receiving apparatus 100 has a so-called multi-screen display function. For example, when a predetermined key (for example, a dedicated two-screen key) of the remote controller 110 is pressed, the screen is switched to a two-screen display.

  In addition, the control unit 108 switches the input of one of the screens displayed on the multi-screen to another input, that is, switches the video to another video and displays it according to the operation of the remote controller 110, for example. A multi-screen switching control module (not shown) for controlling the screen. The specific configuration and operation of multi-screen display will be described later.

  In addition, the television broadcast receiving apparatus 100 includes a remote controller 110 and a code receiving module 111. An operation signal (for example, an infrared signal) from the remote controller 110 is received by the code receiving module 111 and decoded by the control module 108. For example, when the operation signal for channel selection or desired external input switching is received by the code receiving module 111, the control module 108 controls each part of the signal processing module 103 and the like based on the received operation signal. The video display, audio playback, or external input switching of the channels is performed.

  More specifically, for example, when the user presses the input switching button of the remote controller 110, the code receiving module 111 receives an input switching signal (a code for instructing input switching). Then, an operation menu for switching external input is displayed. In a state where the operation menu is displayed, the user operates a cross key or a predetermined button on the remote controller to select one of the input sources (DTV, HDMI1, HDMI2, HDMI3, etc.) displayed on the operation menu. One can be selected. Note that switching (selection) of the external input can also be performed using a direction key such as an up / down key among the buttons of the remote controller.

  In addition, the television broadcast receiving device 100 includes an HDMI connection module 112. Therefore, the television broadcast receiving apparatus 100 can be connected to a plurality of devices (for example, a DVD recorder, an AV amplifier, etc.) having an HDMI terminal via the HDMI connection module 112. In FIG. 1, it is connected to the HDMI-CEC device 113 via the HDMI connection module 101. The control module 108 can perform bidirectional communication with the HDMI-CEC device 113 via the HDMI connection module 112 based on the CEC standard. That is, the HDMI-CEC device 113 can be controlled from the television broadcast receiving apparatus 100 by using the remote controller 110 or the like. For example, assuming that the HDMI-CEC device 113 is a DVD recorder and receives a control signal (for example, a signal for playback / stop / recording) from the remote controller 110 to the DVD recorder, playback / stop, etc. are performed via an HDMI communication cable. An instructing control signal is transmitted to the DVD recorder. Then, playback and stop of the DVD recorder can be controlled.

  Moreover, the television broadcast receiving apparatus 100 has a one-touch play function in digital devices connected to each other. The one-touch play function in the present embodiment is an operation for operating the HDMI-CEC device 113 (for example, the HDMI-CEC device 113 when the HDMI-CEC device 113 such as a DVD recorder or the like is connected). When a playback button or menu display button of the main body or the remote control, or a key for performing playback operation of the HDMI-CEC device 113 provided in the remote controller 110 is performed), the input of the TV is automatically linked to that. This is a function that realizes an operation for switching to the CEC device 113 and a reproduction operation accompanying it (reproduction of a DVD stored in a DVD recorder, reproduction of a program stored in an HDD of a DVD recorder, etc.). In addition, when the HDMI-CEC device 113 is a digital movie camera, the playback operation of still images and moving images recorded on a recording medium stored in the digital movie camera can be realized with the one-touch play function.

  The television broadcast receiving apparatus 100 includes a USB terminal 114. Accordingly, the television broadcast receiving apparatus 100 can be connected to a device having a USB terminal (for example, an external HDD) via the USB terminal 114.

  Further, the television broadcast receiving apparatus 100 includes an external input terminal 115 (composite, component, etc.) other than the HDMI terminal and the USB terminal. Therefore, it is possible to connect to the external device 116 via the external input terminal 115.

  Note that an external device (connection partner device) may be physically connected by a communication cable or the like via the HDMI connection module 112, the USB terminal 114, the external input terminal 115, or the like, or may be connected wirelessly by wireless communication. Is possible. Regardless of HDMI or USB, as an interface to which an external device is connected, it is preferable that both video and audio can be transmitted together with a predetermined cable. In this embodiment, HDMI, USB, and the like are described, but other communication standards may be used. In the above example, the one-touch play function related to the HDMI-CEC device 113 has been described. However, the one-touch play function can also be realized in relation to an external device using a communication standard other than HDMI.

  Next, referring to the flowchart of FIG. 2 and FIGS. 3 to 5 regarding the multi-screen display process and the input switching process including the one-touch play in the multi-screen display of the television broadcast receiving apparatus 100 according to the first embodiment. To explain.

  First, according to the operation of the remote controller 110, the screen division module of the control unit 108 controls to divide the screen of the video display unit 106 into a multi-screen (two screens in this embodiment) area. Specifically, for example, when the two-screen key of the remote controller 110 is pressed, the screen is switched from the one-screen display to the two-screen display (step S1001). Note that, when the two-screen display is performed, the two-screen key may be pressed again to return to the one-screen display.

  FIG. 3 is an example of a two-screen display. As shown in FIG. 3, the screen of the video display unit 106 is displayed divided into a first screen area A and a second screen area B. In the first screen area A in the present embodiment, an image of a digital terrestrial program (RF input) that was viewed during one-screen display is displayed, and in the second screen area B, the external device 116 is displayed. The video (for example, PC input) is displayed.

  Further, an audio right icon 120 and an operation right icon 121 are displayed above the first screen area A. The sound right icon 120 indicates which screen sound is controlled to be output from the speaker 107 during multi-screen display. Therefore, in the state of FIG. 3, the sound on the first screen area A side is output from the speaker 107. The operation right icon 121 indicates which screen can be operated by the remote controller 110 for, for example, volume adjustment, channel switching, input switching, and the like during multi-screen display. Therefore, in the state of FIG. 3, the first screen area A side can be operated by the remote controller 110.

  Next, the one-touch play operation of the HDMI-CEC device 113 is performed. That is, an operation for a user to operate the HDMI-CEC device 113 (for example, a playback operation or a menu button of the main body of the HDMI-CEC device 113 or a remote controller, or a playback operation of the HDMI-CEC device 113 provided in the remote controller 110). And so on (step S1002). For convenience, this is referred to as a first one-touch play operation. Then, the HDMI-CEC command is transmitted from the HDMI-CEC device 113 to the television broadcast receiving apparatus 100, and the television broadcast receiving apparatus 100 receives the HDMI-CEC command (step S1003).

  Next, the control unit 108 receives the current input of the first screen area A having the audio right command 120 (in this embodiment, the video signal of the terrestrial digital program displayed before the one-touch play operation). Control is performed so as to store the information in the storage module 109 (step S1004). The current input information stored here is information used for input switching in step 1008, which will be described later, and is, for example, information on the input terminal, channel name of the program, broadcast station name, program name, and the like. .

  Next, the video signal supplied from the HDMI-CEC device 113 is displayed in the first screen area A under the control of the control unit 108. That is, as shown in FIG. 4, screen input switching to the HDMI-CEC device 113 is performed for the first screen area A (step 1005). In this case, as shown in FIG. 4, since the audio right icon 120 and the operation right icon 121 are in the first screen area A, the audio from the HDMI-CEC device 113 is used instead of the audio of the terrestrial digital program. Is output.

  In addition, the control unit 108 displays the video signal supplied from the HDMI-CEC device 113 in the first screen area A, and a GUI (Graphical User Interface) message 122 is displayed on the video display unit 106 for a certain period (for example, The display is controlled to be displayed for 5 seconds (step S1006). In response to the first operation, the GUI message 122 receives the input (in this embodiment, the HDMI-CEC device 113) displayed in the first screen area A in step 1005, the audio right icon 120, and the operation right. This is a message indicating to the user that switching to the second screen area without the icon 121 is possible by pressing a predetermined key (in this embodiment, the reproduction key) again. Note that the GUI message 122 may be an icon message that does not include characters. This operation prompted by the message is referred to as a second one-touch play operation for convenience.

  The predetermined key used for the second one-touch play operation is, for example, an operation for the user to operate the HDMI-CEC device 113 (for example, a playback button or a menu button on the main body of the HDMI-CEC device 113 or a remote controller, or a remote controller 110). It is preferable that the key is used for a playback operation of the HDMI-CEC device 113 provided, and more preferably the same as the key used in the first one-touch play operation. Thereby, the user can switch the screen displayed by the first one-touch play operation by continuously pressing one key.

The GUI message 122 can also be referred to as a selection screen for allowing the user to select whether or not to perform the second one-touch play operation.
When the second one-touch play operation is not performed during the display period of the GUI message 122 (No in Step 1007), the GUI message 122 disappears and the state shown in FIG. 4 (from the HDMI-CEC device 113 to the first screen area A) is displayed. And the video from the personal computer input is displayed in the second screen area B).

  On the other hand, when the second one-touch play operation is performed during the display period of the GUI message 122 (Yes in step 1007), the control module 108 is displayed in the first screen area A as shown in FIG. In place of the video (video of the HDMI-CEC device 113), the input video signal stored in step 1004 (in this embodiment, the video signal of the terrestrial digital program displayed before the first one-touch play operation is performed) ) And the video displayed on the first screen area A (video of the HDMI-CEC device 113) is displayed on the second screen area B (step 1008). In this case, as shown in FIG. 5, since the audio right icon 120 and the operation right icon 121 are maintained in the first screen area A, the sound of the terrestrial digital program is output instead of the HDMI-CEC device 113. Is done.

  As described above, in the television broadcast receiving apparatus 100 of the first embodiment, the input switching of the external device (HDMI-CEC device 113) in the multi-screen display is performed only by continuously performing the one-touch play operation at least twice. Can be done freely. Switching from FIG. 3 to FIG. 5 is realized by only one-touch play operation without performing troublesome operations such as pressing the input switching button of the remote controller 110 and switching the voice right icon 120 and the operation right icon 121. it can. Therefore, the usability of the one touch play at the time of multi-screen display is improved.

  Next, a second embodiment of the present invention will be described. The second embodiment is different from the first embodiment in that a video from an external device (HDMI-CEC device 113) that is operated by one-touch play during the two-screen display (S1001) is already displayed.

  The multi-screen display processing and input switching processing including one-touch play in multi-screen display of the television broadcast receiving apparatus 100 according to the second embodiment will be described with reference to the flowchart of FIG. 6 and FIG. Note that the description of the same points as in the first embodiment is omitted or simplified.

  First, it is assumed that the user is viewing the video from the HDMI-CEC device 113 on a single screen. Next, in accordance with the operation of the remote controller 110, the screen division module of the control unit 108 controls to divide the screen of the video display unit 106 into multiple screens (two screens in this embodiment) (step 2001).

  FIG. 7 is an example of a two-screen display. As shown in FIG. 7, in the first screen area A in the present embodiment, the video input from the HDMI-CEC device 113 that was viewed during one-screen display is displayed, and the second screen area B The video of the external device 116 (for example, personal computer input) is displayed. In the state of FIG. 7, the sound of the HDMI-CEC device 113 is output from the speaker 107. Further, in the state of FIG. 7, the volume control or the like can be performed with the remote controller 110 on the first screen area A side.

  Next, the first one-touch play operation of the HDMI-CEC device 113 is performed (step 2002). Then, the HDMI-CEC command is transmitted from the HDMI-CEC device 113 to the television broadcast receiving apparatus 100, and the television broadcast receiving apparatus 100 receives the HDMI-CEC command (step S2003).

  Next, in a state where the video signal supplied from the HDMI-CEC device 113 is displayed on the first screen area A, the control unit 108 displays a GUI message on the video display unit 106 in the same manner as shown in FIG. Control is performed so that 122 is displayed for a certain period (for example, 5 seconds) (step S2004).

  When the second one-touch play operation is not performed during the display period of the GUI message 122 (No in step 2005), the GUI message 122 disappears and the state shown in FIG. 7 (from the HDMI-CEC device 113 to the first screen area A) is displayed. And the image from the personal computer is displayed in the second screen area B).

  On the other hand, when the second one-touch play operation is performed during the display period of the GUI message 122 (Yes in step 2005), the control module 108 displays the video (HDMI-CEC device 113) displayed in the first screen area A. The video signal of the last memory input in the storage module 109 is displayed in place of the video), and the video (video of the HDMI-CEC device 113) displayed in the first screen area A is displayed in the second screen area. B is displayed (step 2006).

  The input video signal that has been last-memory is, for example, a video signal related to a video that was viewed immediately before switching to the video of the HDMI-CEC device 113 that was originally viewed. For example, when a terrestrial digital program is viewed before viewing the HDMI-CEC device 113, the input video signal of the terrestrial digital program is an input video signal stored in the last memory. Therefore, in this case, as shown in FIG. 5, instead of the video (video of the HDMI-CEC device 113) displayed in the first screen area A, the video signal of the last memory input (in the second embodiment) The video signal of the terrestrial digital program that was initially viewed) is displayed, and the video (video of the HDMI-CEC device 113) displayed in the first screen area A is switched to the second screen area B. It is displayed (step 2006). In this case, as shown in FIG. 5, since the audio right icon 120 and the operation right icon 121 are maintained in the first screen area A, the sound of the terrestrial digital program is output instead of the HDMI-CEC device 113. Is done.

  Note that the input video signal to be last-memory can be arbitrarily changed according to the video that was viewed immediately before the video of the HDMI-CEC device 113. That is, when the video from the external device 116 is viewed immediately before the video of the HDMI-CEC device 113, the input video signal to be last-memory is the video signal from the external device 116. In addition, when a BS input video is viewed immediately before the HDMI-CEC device 113 video, the video signal is a BS input.

  In the second embodiment, switching from FIG. 7 to FIG. 5 is performed by troublesome operations such as an input switching operation (operation of the input switching button) of the remote controller 110 and an operation of the voice right icon 120 and the operation right icon 121. Instead, it can be realized by simply performing a one-touch play operation.

  Next, a third embodiment of the present invention will be described. Also in the third embodiment, as in the second embodiment, an image from an external device (HDMI-CEC device 113) that is operated by a one-touch play during the two-screen display is already displayed.

  The multi-screen display processing and input switching processing including one-touch play in multi-screen display of the television broadcast receiving apparatus 100 according to the third embodiment will be described with reference to the flowchart of FIG. 8 and FIG. The description of the same points as in the first and second embodiments is omitted or simplified.

Steps 3001 to 3005 are the same as steps 2001 to 2005 in the second embodiment, and thus description thereof is omitted.
If the second one-touch play operation is not performed during the display period of the GUI message 122 (No in step 3005), the GUI message 122 disappears and the state shown in FIG. 7 (from the HDMI-CEC device 113 to the first screen area A) is displayed. And the image from the personal computer is displayed in the second screen area B).

  On the other hand, when the second one-touch play operation is performed during the display period of the GUI message 122 (Yes in Step 3005), the control module 108 displays the video (HDMI-CEC device 113) displayed in the first screen area A. The video signal input in the second screen area B is displayed in place of the video) and the video (the video of the HDMI-CEC device 113) displayed in the first screen area A is displayed in the second screen area. Control is performed to display on B (step 3006). That is, the input of the first screen area A and the input of the second screen area B are interchanged. In this case, as shown in FIG. 9, since the audio right icon 120 and the operation right icon 121 are maintained in the first screen area A, the audio of the personal computer is output instead of the HDMI-CEC device 113, and the personal computer The volume of the screen area A can be controlled by the remote controller 110.

  In the third embodiment, switching from FIG. 7 to FIG. 9 is performed by troublesome operations such as an input switching operation (operation of the input switching button) of the remote controller 110 and an operation of the voice right icon 120 and the operation right icon 121. Instead, it can be realized by simply performing a one-touch play operation.

  As described above, in any of the first to third embodiments, the one-touch play operation is continuously performed, so that the connection partner device (HDMI-CEC device 113 in the above embodiment) on the screen is displayed on the screen. Switching can be done freely.

  In the above-described embodiment, the DVD player is mainly described as an example of the HDMI-CEC device 113. However, in addition to this, an external device such as a digital camera having a HDMI-CEC function or a personal computer may be used. In other words, the external device that realizes the one-touch play function in relation to the television broadcast receiving device 100 is not particularly limited. In addition to the HDMI-CEC, it is possible to use a communication standard that can realize a one-touch play function in relation to the television broadcast receiver 100.

  Further, in the above embodiment, switching of the first screen area A to the second screen area (S1008, S2006) of the input of the HDMI-CEC device 113 has been described. However, by continuously pressing the key for the one-touch play operation, the input of the HDMI-CEC device 113 is switched from the second screen area B to the first screen area A and vice versa. Furthermore, a continuous operation (so-called toggle operation) is also possible.

  Moreover, although the said embodiment demonstrated the screen switching of the input of the HDMI-CEC apparatus 113 in two-screen display, it is not limited to this. For example, when the control module 108 is configured to be able to switch between two-screen display and one-screen display by a one-touch play operation, an image from the HDMI-CEC device 113 is displayed in the first screen area A of the two-screen display. In the second screen area B of the two-screen display, the state in which the video from the HDMI-CEC device 113 is displayed, and the state in which the video from the HDMI-CEC device 113 is displayed in one-screen display. A toggle operation is also possible. Thereby, it is possible to sequentially switch between the single screen display and the double screen display by simply performing the one touch play operation, and the usability of the one touch play is improved.

  In addition, the present invention can be applied to multi-screen display such as three-screen display and four-screen display rather than two-screen display. For example, when the first embodiment is applied to a three-screen display, the screen is switched to an input that stores a screen area (having the audio right 120 and the operation right 121) of the HCMI-CEC device 113 in step 1008, and the others.
