Description

  The present invention relates to a television receiver, and more particularly to a television receiver equipped with a multi-screen function.

  In recent years, in television broadcasting, since the broadcasting form has shifted from analog to digital, and the number of channels has increased rapidly, so-called multi-display that simultaneously displays a plurality of programs input from a plurality of tuners on a plurality of screens. Digital televisions capable of screen display have been proposed.

In general households, it has become widespread that an external website is accessed via the Internet and information is displayed on the screen for browsing.
Under such circumstances, one television receiver is provided that can simultaneously view a plurality of digital television broadcast programs and browse web pages on the Internet.

Such a television receiver has the following problems.
(1) In multi-screen display, it is not easy to switch between screens.
For example, in Patent Document 1, it is configured to switch between displaying a TV program and a browser screen independently or simultaneously using a multi-screen display. The indicated index is displayed on the screen. Further, when switching to a plurality of screen displays, an index for explaining what each screen is and an index indicating the screen on which the sound is output are displayed. Thus, in a television receiver having a web page browsing function, display switching between a television program and a browser screen can be performed efficiently.
However, in Patent Document 1, switching is performed when a television program and a web page or two television programs are displayed on two screens, and no screen switching is performed on multiple screens of three or more screens.

(2) An input operation can be performed only on the main screen to be operated.
For example, when a TV program is displayed on one screen, a web page is displayed on another screen, and a TV program is displayed as the main screen, the main screen is displayed on the TV in order to perform an input operation on the web page. It is necessary to perform an operation of switching from a program screen to a web page screen, performing an input operation, and then returning the television program screen to the main screen again, which complicates the operation.

(3) The sound of the main screen is reproduced.
For example, in Patent Document 2, the user's line of sight is detected, and the sound of the screen that the user is viewing is output. In this case, sound is not reproduced on a screen other than the screen that the user is viewing.
In Patent Document 3, the sound of the main screen is output from a television speaker, the sub screen is output to headphones, and the sound of a plurality of screens is reproduced at the same time. However, in this case, the output destination of the audio is fixed, and cannot be used for applications with more than three screens.

  The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a usability television receiver equipped with a multi-screen display function of three or more screens.

In order to solve the above-described problems, a television receiver of the present invention is a television receiver equipped with a multi-screen function, and a screen dividing unit that instructs to divide one screen into a plurality of screens, and the screen dividing unit. Corresponding to each of the plurality of screens instructed by the multi-screen processing unit, the plurality of audio output units, and the plurality of audio output units that output the plurality of input videos to the display unit in association with each other. A voice switching means for switching a screen for outputting a voice from a plurality of screens; and a voice corresponding to the screen switched by any of the plurality of voice switching means, and the voice switching means corresponding to the voice switching means. Voice selection means for outputting to the voice output means.
Thereby, it is possible to output sound to a plurality of independent sound output means irrespective of the operation target screen.

  The voice selection means can save power by turning off the power of the voice output means when no voice is output to the voice output means.

Furthermore, an operation screen switching means for switching a screen to be operated among the plurality of screens is provided, so that the screen to be operated can be switched independently of the voice switching.
At this time, on the screen switched by the voice switching unit or the operation screen switching unit, an indicator corresponding to the type of the switching unit is displayed, and any screen is output to the operation unit or the voice unit. Screens can be clearly distinguished.
Further, by classifying the key into a key for operating the web browser and other keys, the web browser can be operated without switching the operation target screen by the operation screen switching means.

In addition, a web browser that acquires a web page by connecting to a network and displays the web page on any of the plurality of screens, and information indicating high-definition content such as full HD on the web page acquired by the web browser Resolution determination means for determining whether the web page acquired by the web browser includes information indicating high-definition content such as full HD. The multi-screen processing means displays the web page on one screen.
Thereby, high-quality content can be displayed with an optimal screen size.

Furthermore, the user can specify the key type (for example, the end key, the two-screen key, the operation switching key, and the screen split key) when changing from one split screen type to another split screen type. May be generated.
Thereby, since the user can set the relationship between the type of screen division and the input key, usability is further improved.

  In addition, information for restoring the display content of one screen or multiple screens displayed when the power is turned off is stored in a nonvolatile storage means, and information for restoration from the storage means is stored when the power is turned on. Acquire and restore the display content of one screen or multiple screens immediately before the power is turned off, or to restore the display content of the screen that was the operation target when the power was turned off Information is stored in a non-volatile storage means, information for restoration is acquired from the storage means when the power is turned on, and the display content of the screen that was the operation target immediately before the power is turned off is restored to one screen. You may make it display.

In addition, regardless of the content displayed on the single web browser screen or web browser that was displayed when the power was turned off, the TV screen or external input screen that was the target of the operation when the power was turned off is displayed. Information for restoring the contents is stored in the non-volatile storage means, and when the power is turned on, the information for restoration is acquired from the storage means, and the display contents of the TV screen or the external input screen immediately before the power is turned off are obtained. You may make it restore.
Any one of these display screen restoration methods may be selectable in advance by the user.

Alternatively, the startup screen can be selected by the user from among three screens, two screens, and one screen display, and information for restoring the display content of one screen or multiple screens displayed when the power is turned off is nonvolatile. The information stored in the storage unit may be stored and information for restoration from the storage unit may be acquired when the power is turned on, and the display content immediately before the power is turned off may be restored corresponding to the start-up screen.
Here, when the user selects the one-screen display of the web browser as the start-up screen, information for restoring the web page displayed when the power is turned off is stored in the non-volatile storage means, At the time of turning on, information for restoration is acquired from the storage means, and the web page immediately before the power is turned off is restored and displayed on one screen.

  Further, a program for causing a computer to function is created as each means of the television receiver configured as described above, or the program is recorded on a computer-readable recording medium, and this program is recorded on the television. The above problem can also be solved by executing the program with a computer provided in the receiving apparatus.

  According to the present invention, in a television receiver equipped with a multi-screen function of three screens or more, a television with usability that allows a user to reliably and easily perform screen switching, input operation, and audio output switching operation. John receiver was able to be provided.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a television receiving apparatus according to an embodiment of the present invention. In the figure, the television receiving apparatus 100 includes a plurality of input units 11, a web browser 12, a resolution determining unit 13, The operation unit 14, the control unit 15, the multi-screen processing unit 16, the OSD processing unit 17, the display unit 18, the audio selection unit 19, the speaker audio output unit 20, the headphone audio output unit 21, and the storage unit 22 are configured. .

  The television receiving apparatus 100 is connected to a network such as the Internet, and acquires information related to a broadcast program from a web server connected to the network using a web browser built in the apparatus. Thus, it can be displayed on the screen of the device together with the broadcast program.

  In addition, the television receiving apparatus 100 can display a plurality of screens at the same time, and can display images of television programs received by different input units 11 and images input from external terminals on the plurality of screens. The output screen of the web browser can be displayed.

For example, when the screen of the display means is divided and displayed, it is divided as shown in FIG.
FIG. 2A shows a screen that is not divided. Hereinafter, displaying on one screen is referred to as normal display. FIGS. 2B and 2C are examples in which the screen is divided into two screens, and FIGS. 2D and 2E are examples in which the screen is divided into three screens. This is called display.

  In the case of this multi-screen display, the user may select a predetermined two-screen division or three-screen division by pressing a specific key, and the arrangement and size of the divided screen may be set on the television receiver side. You may make it perform automatically.

  The operation unit 14 includes a plurality of switches provided on, for example, a front panel of the television receiver 100 and a remote controller. When the user performs function switching, adjustment, operation setting, and the like of the television receiver 100. The input information is transferred to the control unit 15.

  The remote controller is generally equipped with numeric keys used when switching broadcast channels or entering numeric / character data, arrow and enter keys for selecting items on the screen, return key, and screen guidance. Therefore, it has the following keys in addition to color keys (blue, red, green and yellow) for various selections, a volume adjustment key, a power key for turning on / off the power, and the like.

The two-screen key is a key for switching from the normal display to the two-screen display when pressed for the first time and switching from the two-screen display to the normal display by pressing again.
The end key is a key for ending current multi-screen display and switching to normal display.

  The operation screen switching key is a key for switching a screen to be operated every time the multi-screen display is pressed. For example, as illustrated in FIG. 3, when three screens, a screen for displaying two TV programs and a web browser screen, are displayed, each time the operation screen switching key is pressed, the remote controller icon is displayed. The screen on which the icon is displayed is the operation target. By selecting the operation target, operations such as channel selection, screen adjustment, and volume adjustment can be performed. The icon is not limited to the icon of the remote controller, but may be any index that can identify the operation target.

  The speaker voice switching key is a key for switching a target screen for outputting voice from the speaker. For example, as shown in FIG. 4, when three screens, a screen for displaying two TV programs and a web browser screen, are displayed, a speaker icon is displayed each time the speaker voice switching key is pressed. Audio corresponding to the screen on which the icon is displayed is output to the speaker. The above icon is not limited to the speaker icon, and may be any indicator that can determine that sound is output from the speaker.

  The headphone audio switching key is a key for switching a target screen for outputting audio from the headphones. For example, as illustrated in FIG. 5, when a screen for displaying two TV programs and a web browser screen are displayed, each time the headphone audio switching key is pressed, a headphone icon is displayed. Audio corresponding to the screen on which the icon is displayed is output to the headphones. The above icon is not limited to the headphone icon, but may be any indicator that can determine that sound is output from the headphone.

Since the speaker audio switching key, the headphone audio switching key, and the operation screen switching key can be operated independently, it is possible to change the program of the other TV program while viewing one TV program.
In addition, when displaying on a multi-screen, an “icon” is displayed to indicate which screen the sound is being output, so that the user can easily understand which screen the sound is for.

The screen division key is a key for selecting a multi-screen display mode. When this screen division key is pressed, for example, a selection menu as illustrated in FIG. 6 is displayed. In FIG. 6, 601 is a title of the displayed selection menu “screen division”, 602 is a normal display option (FIG. 2A), and 603 is two screens of a TV program display screen and a web browser screen. A split option (FIG. 2 (B) or (C)), 604 is a three-screen split option (FIG. 2 (D) or (E)) of two screens for displaying TV programs and a web browser screen, 605 is The web browser screen options (FIG. 2A) are shown.
Then, when the user moves the cursor of the operation unit 14 and selects a desired item from these using the enter key, the screen is divided.

  The display screen of the keys described above varies depending on the order of operation. FIG. 7 is a diagram showing the relationship between the pressed key and the displayed screen. In FIG. 7, there are five screen displays. By pressing a key surrounded by a square, The screen is displayed.

  FIG. 8 shows the pressed key and five screen division states (a TV program display screen, two TV program display screens, one TV program display screen and a web browser screen, and two TV program display screens. FIG. 7 is a state transition diagram for determining the relationship between the web browser screen and the web browser screen), and is a detailed representation of the relationship of FIG. In FIG. 8 as well, the screen division state surrounded by a circle is changed to a state surrounded by a circle, and what kind of determination is made when a key is pressed in this state, and the transition to the next screen division state is determined. Show.

For example, when a two-screen key is pressed during a normal display screen, the screen is switched to a two-screen display.
During this two-screen display, each time the operation switching key is pressed, the screen to be operated is switched, and the normal display screen is restored by pressing the end key or the two-screen key.
In addition, when a screen split key is pressed, a split screen can be selected from the displayed items.

The user may be able to set the above-described screen transition state (relation with a key used when shifting from one-screen display or multi-screen display to another screen display) using a menu.
For example, when the user designates the screen transition state setting from the menu, the predetermined divided screen type (for example, the above five screen divided states) is presented, and another divided screen type is displayed. The above-described screen transition state is generated by designating the key type (for example, the end key, the two-screen key, the operation switching key, and the screen division key) when changing to the screen type.

Furthermore, in this embodiment, by classifying into a key for operating the web browser and other keys, it is possible to operate the web browser and the television program without operating the operation switching key.
For example, as keys that can be used in a web browser, there are a numeric key, an arrow key, a decision key, a return key, and a color key. Other keys can be used on the screen displaying the TV program.

For example, FIG. 9 is divided into two screens, a television program is displayed on the left screen, and a web browser is displayed on the right screen. Here, by pressing a key for operating the web browser as described above, it is possible to input even if the screen of the web browser is not an operation target.
Further, by pressing a key other than a key for operating the web browser, for example, a channel up / down key, a channel can be selected even if it is not an operation target.

FIG. 10 is divided into two screens for displaying a television program and a web browser screen. In this case, the web browser can be directly operated by the above-described key for operating the web browser. However, for the operation of the TV program, the operation target is clearly indicated by the operation screen switching key and the web browser is operated. It will be operated using the keys.
By providing the keys as described above and limiting the function range in which the keys can be operated, it is possible to perform an operation from the displayed screen without specifying an operation target.

The control unit 15 includes a CPU (Central Processing Unit), and controls the overall operation of the television receiving device 100, adjusts functions, and the like. Connected to the unit 14, the multi-screen processing unit 16, the OSD processing unit 17, the voice selection unit 19, and the storage unit 22.
When the channel selection of the broadcast channel is performed by the operation unit 14, the control unit 15 stores the channel selection channel as input information corresponding to the operation target screen and also corresponds to the operation target screen. The selected channel is notified to the tuner of the input unit 11.

  A display status table used in the following description will be described. The display status table is provided in the storage unit 22 and includes entries for the number of divided screens as illustrated in FIG. 11, and stores the following data for each screen.

Screen ID: An identifier for identifying a divided screen.
Input information: Indicates from where the displayed image is input, and holds a channel number (or external file name) or URL.
Screen position: A coordinate position indicating where this screen is displayed.
Screen size: A dimension representing the size of the screen, for example, expressed in units of pixels.
Operation target flag: Classification information indicating whether this screen is an operation target (“true”) or not (“false”).
Speaker flag: Classification information indicating whether audio data for this screen is output to the speaker (“true”) or not (“false”).
Headphone flag: Classification information indicating whether audio data for this screen is output to headphones (“true”) or not (“false”).
High-definition flag: Classification information indicating whether or not the content of the web page displayed on this screen includes high-definition information (“true”) or not (“false”).

  The storage unit 22 includes a volatile memory and a non-volatile memory. In the non-volatile memory, in addition to various application programs for executing various functions of the apparatus, various data and channels for OSD (On Screen Display) processing. Data for channel selection, data related to multi-screen display (for example, display status table, number of screen divisions, screen division state, screen state transition, etc.) are stored, and volatile memory is used as work memory.

  The control unit 15 performs the following processing on the following keys sent from the operation unit 14 respectively.

(1) Various selections from the two-screen key, end key, and screen split key:
When the input of these keys is received from the operation unit 14, the next screen division state is determined with reference to the state transition shown in FIG. 8, and the number of screen divisions and the determined screen division state are stored in the storage unit 22. Remember me. When the screen division state is determined, the screen position and the screen size are calculated for each screen and stored in the display status table provided in the storage unit 22. This screen division is performed in such a ratio that the scroll of the web browser screen is reduced as much as possible in consideration of the image quality and data size of the displayed video and image data.

(2) Operation screen switching key:
When it is received from the operation unit 14 that the operation screen switching key has been input, the display status table is searched in order of the screen, the screen ID having the operation target flag “false” is searched, and the operation target flag of the screen is set to “true”. The operation target flag of the screen ID that was “true” until now is set to “false”. If there is no screen whose operation target flag is “true”, one of the screens registered in the display status table is selected, and the operation target flag for that screen is set to “true”.
In this way, an icon indicating that the operation target flag is “true” is displayed, and the OSD processing unit 17 is notified to delete the icon from the “false” screen.

(3) Speaker voice switching key:
When the input of the speaker voice switching key is received from the operation unit 14, the display status table is searched in screen order for the screen ID having the speaker flag “false”, and the speaker flag of the screen is set to “true”. The speaker flag of the screen ID that was “true” is set to “false”. If there is no screen whose speaker flag is “true”, one of the screens registered in the display status table is selected, and the speaker flag for that screen is set to “true”.
In this way, an icon indicating that sound is being output from the speaker is displayed on the screen where the speaker flag is “true”, and the OSD processing unit 17 is notified to delete the icon from the screen where “false” is displayed. Then, the voice selection unit 19 is notified that the output voice from the speaker has been changed.

If there is no screen whose headphone flag is “true”, one of the screens registered in the display status table is selected, and the headphone flag for that screen is set to “true”.
In this way, an icon indicating that sound is output from the headphones is displayed on the screen where the headphone flag is “true”, and the OSD processing unit 17 is notified to delete the icon from the screen where “false” is displayed. Then, the sound selection unit 19 is notified that the output sound from the headphones has been changed.

(5) Power on and off:
Information for restoring display content displayed on one screen or multiple screens displayed when the power of the television receiver 100 is turned off, that is, a display status table at power-off (this includes each The channel selection channel for the divided screen, the URL address in the case of Internet connection, etc. are held), the number of divided screens, and the screen state are stored in the nonvolatile storage unit 22. Then, when the power is turned on, information for restoring the display content displayed on the screen immediately before the power is turned off is acquired from the storage unit 22, and the display displayed on one screen or a multi-screen just before the power is turned off. Restore the contents.

Alternatively, when the power is turned off, information (for example, a channel selection channel or a URL) for restoring the display content of the screen that is the operation target is stored in the nonvolatile storage unit 22 with reference to the display status table. To do. Then, when the power is turned on, information to be restored is acquired from the storage unit 22, and the display content of the screen that is the operation target immediately before the power is turned off (for example, the channel that was selected immediately before the power was turned off last time) Or a web page displayed on a web browser) may be restored and displayed on a single screen.
Furthermore, the above two methods when the power is turned off may be selectable by the user.

Alternatively, the startup screen when the power is turned on can be selected by the user from among three screens, two screens, and one screen display, and a one-screen or multi-screen display that was displayed when the power was turned off. Information for restoring the contents is stored in the nonvolatile storage unit 22.
Then, when the power is turned on, information to be restored from the storage unit 22 may be acquired according to the selected startup screen, and the display content immediately before the power off corresponding to the startup screen may be restored.

Here, when the number of screens of the startup screen is smaller than the number of screens when the power is turned off, restoration is performed using the restoration information of the screen when the power is turned off, which can support the startup screen.
For example, if the power-off screen is “two TV program display screen and web browser screen” and the start-up screen is “one TV program display screen and web browser screen”, the main TV of the off time is displayed. The screen or the TV screen that has been operated is activated as the TV screen when the power is turned on. As for the web browser screen, the web page displayed when the power is turned off is restored and displayed on the web browser screen of the startup screen.

If the number of startup screens when the power is turned on is larger than the number of screens when the power is turned off, the screen is displayed as a clean display if there is no corresponding screen to be restored.
In addition, when the user selects the web browser screen as the start screen for single-screen display, the web page of the screen (which may be single-screen display or multi-screen display) displayed when the power is turned off Information (for example, URL of a web page) is stored in the storage unit 22, and when the power is turned on, the information for restoration is acquired from the storage unit 22, and the web page immediately before the power is turned off is obtained. Restore as one-screen display. If there is no screen displaying a web page when the power is turned off, a predetermined web page may be displayed on the web browser screen when the power is turned on.

  In this way, since the same screen as the previous screen or a predetermined screen is displayed, the user is not confused. In particular, if one television program display screen is selected as the startup screen, the device is a television, so that the user expects the television screen to be displayed when the power is turned on, so a natural response is made. The

(6) Keys other than the above:
In the case of a key for operating the web browser, the input key is transferred to the web browser 12. In the case of a channel selection key, the corresponding input unit 11 is notified that the input corresponds to the screen to be operated.

  The input unit 11 includes a tuner, a separation unit, and a decoding unit. When a plurality of broadcasts can be received at the same time, the input unit 11 includes as many tuners, separation units, and decoding units as can be received simultaneously.

The plurality of tuners receive the broadcast wave of the channel selected by each through an antenna, demodulate the received broadcast wave, and perform processing such as error correction to obtain a TS (Transport Stream) signal. , And supply to the separation unit.
The separation unit is configured by a number of separation units according to the number of tuners, and separates a TS (Transport Stream) signal into a video stream, an audio stream, and EPG (Electronic Program Guide) information, and separates the separated video stream and audio stream. Is supplied to the decoding unit.
The decoding unit includes decoding units corresponding to the number of tuners. The decoding unit decodes the audio stream and supplies it to the audio selection unit 19 as uncompressed digital audio data. The digital video data is supplied to the multi-screen processing unit 16.

  Next, when accessing the Internet, when the screen selection for Internet selection is performed, the control unit 15 connects to the network, and further starts up the web browser 12 to register a pre-registered URL (Uniform Resource Locator). To access the data, import the data that constitutes the page, refer to the display status table, build the browser screen so that the screen size is divided into screens, and the built browser screen to the multi-screen processing unit 16 is supplied.

Here, when the multi-screen processing unit 16 receives a notification from the resolution determining unit 13 that the web page includes information indicating high-definition content, the multi-screen processing unit 16 sets the screen size to the size of one screen of the display unit. Build a browser screen that
As described above, when moving to a web page containing information indicating high-definition content (for example, full HD web content), the screen is automatically switched to one screen for normal display. An optimal image size can be displayed without bothering.

  The resolution discriminating unit 13 analyzes the tag of the web page taken in from the network, and indicates that the content of the web page is high definition (for example, information indicating high definition full HD of 1920 × 1080 pixels). Is set to "true" in the high-definition flag on the screen that displays the web page of the display status table, and if there is no information indicating that the content is high-definition, Set “false”. The determination result is notified to the web browser 12 and the multi-screen processing unit 16.

  The OSD processing unit 17 generates OSD display image data such as a menu screen, icons, and guidance supplied from the control unit 15 based on the operation input signal input from the operation unit 14, and generates the generated image data. This is supplied to the screen processing unit 16.

When the high-definition flag of the screen corresponding to the web page of the display status table is “false”, the multi-screen processing unit 16 converts the resolution of the video data supplied from the input unit 11 according to the screen size. The image data and the browser screen supplied from the web browser 12 are combined into one screen image data in accordance with the arrangement position of each screen, and the image data supplied from the OSD processing unit 17 is combined. It is superimposed on the designated screen, converted in accordance with the characteristics of the display means, and supplied to the display unit 18.
Further, when the high definition flag of the screen corresponding to the web page of the display status table is “true”, the multi-screen processing unit 16 displays only the web page as one screen of the display unit even if there is a video of the TV program. To display.

  In addition, when the number of screen divisions is 1, that is, when there is no division, the multi-screen processing unit 16 generates image data obtained by converting the resolution of the video data supplied from the input unit 11 for the video of the TV program. Then, the image data supplied from the OSD processing unit 17 is superimposed, converted according to the characteristics of the display means, and supplied to the display unit 18. Alternatively, for the image of the web browser, the image data supplied from the OSD processing unit 17 is superimposed on the browser screen supplied from the web browser 12, converted according to the characteristics of the display means, and supplied to the display unit 18.

  The display unit 18 includes display means such as an LCD (Liquid Crystal Display) and a PDP (Plasma Display Panel), and outputs the image data supplied from the multi-screen processing unit 16 to the display means.

When notified from the control unit 15 that the output sound from the speaker has been changed, the voice selecting unit 19 refers to the display status table and searches for a screen whose speaker flag is “true” and corresponds to this screen. The audio data supplied from the input unit 11 is supplied to the speaker audio output unit 20, and the audio is output from the speaker.
In addition, when notified from the control unit 15 that the output sound from the headphones has been changed, the voice selecting unit 19 refers to the display status table and searches for a screen with the headphone flag “true”. The audio data supplied from the corresponding input unit 11 is supplied to the headphone audio output unit 21 to output audio from the headphones.

  When all the speaker flags are “false” or when no sound is output to the speaker for a predetermined time, the sound selection unit 19 turns off the power of the speaker and the sound output circuit system. Thereby, power consumption can be reduced.

  By configuring the television receiver according to the embodiment as described above, the user can reliably and easily perform screen switching, input operation, and audio output switching operation with more than three screens with usability. A television receiver equipped with a screen function can be provided.

  Note that the embodiment of the present invention can also be realized by making each function of the above-described television receiver into a computer program, and installing and executing this computer program in the television receiver. Further, the computer program can be recorded on a detachable recording medium or downloaded via a network, so that the transfer can be simplified and implemented easily.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and corrections can be made without departing from the scope of the present invention. That is, in the above embodiment, two screens and three screens are adopted as the multi-screen display, but the present invention can be similarly applied to multi-screen display divided into four or more screens. In the above-described embodiment, the description has been made using headphones, but of course, the present invention can be similarly applied to earphones.
