For example, while you are at home, you can watch movies or dramas provided by pay program providers on video-on-demand, or from external HDD (Hard Disc drive), cloud storage, video posting sites, etc. by ordinary users Browsing the generated content can be done easily with one smart TV.

  As described above, smart TVs have been equipped with advanced interactive functions and extended functions that can meet the demands of various uses in the same way as smartphones and tablets. In accordance with this, smart TVs have been required to have the same operability as smartphones or tablets.

  Features of the smartphone or tablet include an intuitive and arbitrary operation using a touch panel, and the ability to easily incorporate new functions by downloading an application.

  Various devices have been made in the past in order to fuse a conventional television function and an expansion function that can be operated intuitively into one apparatus.

  For example, Patent Document 1 discloses an interphone device capable of sufficiently functioning for both TV viewing and customer viewing.

  Further, Patent Document 2 discloses a digital broadcast receiving device having convenience that can be intuitively operated by realizing an input device for remotely operating a television, that is, a so-called remote controller by a touch panel.

  Patent Document 3 discloses an image display device that realizes using content provided to a mobile phone such as a smartphone or a tablet on a television. This image display apparatus receives a video signal from a mobile phone via an HDMI (registered trademark) conversion circuit. Then, the video signal received from the mobile phone and the broadcast video signal processed by the mobile phone can be divided into an application data area and a TV data area, respectively, and can be mixedly displayed on one screen.

It is comprised with the touch sensor for detecting a position. The touch sensor may be realized by any sensor as long as it can detect contact / non-contact between the indicator and the touch surface. For example, it is realized by a pressure sensor, a capacitance sensor, an optical sensor, or the like.

  The display unit 5 displays the video signal processed by the extended function execution device 1, the video signal processed by the television signal processing device 2, or both. For example, the display unit 5 is realized by a display device such as an LCD (liquid crystal display).

  In the present embodiment, the touch panel 4 and the display unit 5 are integrally formed. The touch panel 4 is connected to the extended function execution device 1 via the connector 8, and a signal such as a contact position detected by operating the touch panel 4 is transmitted to the extended function execution device 1. That is, the input from the touch panel 4 is executed by the extended function execution device 1.

More specifically, FIG. 1 shows a main configuration of the extended function execution apparatus 1 and a main configuration of the television signal processing apparatus 2.

(Extended function execution device 1)
As illustrated in FIG. 1, the extended function execution device 1 includes an extended function control unit 40, a communication unit 31, and a storage unit 50.

  The communication unit 31 transmits / receives information to / from an external device via a network. For example, it is assumed that an information providing server of a company that operates a certain website is connected to the Internet. In this case, the communication unit 31 may access the information providing server via the Internet and download a page designated by the user.

  The storage unit 50 is a storage device that stores various data used by the extended function execution device 1. In the present embodiment, the storage unit 50 stores at least display mode information 51 and screen information 52. Although not shown, the storage unit 50 includes (1) a control program executed by the extended function control unit 40, (2) an OS program, and (3) application programs corresponding to various extended functions executed by the extended function control unit 40.

  The extended function control unit 40 controls the functions of the extended function execution device 1 in an integrated manner. The extended function control unit 40 includes an input determination unit (input determination unit) 41, an operable region correction unit (region specifying unit) 42, and an extended function execution unit 43 as functional blocks. The extended function execution unit 43 includes at least one extended function unit 44 represented by a browser application 44a, a controller application 44b, and the like, and a display instruction unit 45.

  Each functional block of the extended function control unit 40 described above includes, for example, a storage device (storage unit) in which a CPU (central processing unit) or the like is realized by a ROM (read only memory), an NVRAM (non-volatile random access memory), or the like. This can be realized by reading the program stored in 50) into a RAM (random access memory) (not shown) and executing the program.

  The input determination unit 41 processes an input signal generated by a touch operation on the touch panel 4 to determine what touch operation has been performed (touch operation information indicating what touch operation has been performed) Generate). Specifically, the input determination unit 41 specifies the touch position of the indicator based on the detection signal from the touch panel 4 and determines which position on the extended function execution screen has been operated. When the touch position is on the extended function execution screen, the input determination unit 41 supplies touch operation information including the coordinate information of the touch position to any one of the extended function units 44. The input determination unit 41 may supply the touch operation information to an application being executed among the plurality of extended function units 44.

  In the present embodiment, if the input determination unit 41 determines that the touch position is on an area other than the extended function execution screen (such as an area on the TV screen), touch operation information including coordinate information of the touch position May not be transmitted to the extended function unit 44 but may be transmitted to the display instruction unit 45 as it is. In this case, the display instruction unit 45 can notify the touch operation information d3 to the television signal processing device 2.

  The input determination unit 41 can determine whether or not the touch position is on the extended function execution screen by referring to the screen information 52.

  When the extended function execution screen is not displayed on the full screen on the display unit 5, the coordinate system on the display unit 5 (touch panel 4) does not match the coordinate system on the extended function execution screen. In this case, the input determination unit 41 converts the coordinate information of the detected touch position into coordinate information in the coordinate system of the extended function execution screen, and supplies the coordinate information to the extended function unit 44. As a result, each of the extended function units 44 can accurately understand where on the screen generated by itself has been touched, and can correctly execute processing according to the touch operation.

  Further, the input determination unit 41 may acquire a set of points at the touch position (trajectory of movement of the indicator) in time series to determine the type of touch operation. Examples of the type of touch operation include, but are not limited to, single tap (hereinafter referred to as tap), double tap, flick, drag and drop, pinch in, and pinch out. The determined type of touch operation is supplied to the extended function unit 44 or the display instruction unit 45 as touch operation information together with coordinate information.

  The operable region correction unit 42 corrects the touch-operable region on the touch panel 4 in accordance with the display mode transmitted from the television signal processing device 2. In the present embodiment, the area where the extended function execution screen is displayed on the display unit 5 is an area where a touch operation is possible. Therefore, specifically, the operable region correction unit 42 updates the screen information 52 representing the latest position of the extended function execution screen according to the display mode notified from the television signal processing device 2. As a result, the input determination unit 41 can always accurately determine the touch position according to the latest screen layout of the display unit 5.

  The extended function execution unit 43 causes the one or more extended function units 44 mounted on the extended function execution device 1 to execute predetermined processing and cause the display instruction unit 45 to output the execution result of the processing. The extended function execution unit 43 executes processing according to the touch operation information output from the input determination unit 41.

  More specifically, the extended function execution unit 43 includes one or more extended function units 44 and a display instruction unit 45.

  The extended function unit 44 implements various extended functions that the extended function execution device 1 has. As a specific example of the extended function unit 44, the browser application 44a and the controller application 44b have been described here, but are not limited thereto.

  The browser application 44a processes a structured document described in HTML (HyperText Markup Language) or the like, constructs a website screen on which characters and images are appropriately arranged, and provides the screen so that the user can view it. It is. Here, the website screen corresponds to an extended function execution screen.

  The browser application 44a accesses a storage location (such as the information providing server described above) indicated by a URL (Uniform Resource Locator) designated by the user via the communication unit 31, and based on the HTML document downloaded from the storage location. To generate a website screen. The video signal of the website screen generated by the browser application 44a is supplied by the display instruction unit 45 to the television signal processing device 2 via HDMI as an extended function execution screen d1.

  When acquiring the touch operation information from the input determination unit 41, the browser application 44a understands where and how the touch operation is performed on the website screen generated by the browser application 44a. Then, a predetermined process is executed according to the touch operation, and a new screen is generated. For example, when an object (image or character string) with a link on the website screen is tapped, the browser application 44a downloads the linked HTML document and creates a new web based on the downloaded HTML document. Generate a site screen.

  The controller application 44b implements a conventional infrared TV remote controller with software keys and provides it to the user. The controller application 44b generates, as an extended function execution screen, a screen on which software keys virtualizing the TV remote controller are arranged. The generated extended function execution screen is output to the display unit 5 by the television signal processing device 2.

  Users use the digital television 10 such as a medical facility, a care facility, or an accommodation facility where an unspecified number of users use one digital TV 10 or a digital TV 10 installed in a private room of the facility. In a use scene that is replaced by a small-sized device (remote control) provided separately from the housing of the digital TV 10, there is a disadvantage that the possibility of loss or the like increases. For this reason, it is effective to provide a virtual controller on the extended function execution screen together with the television screen because such inconvenience can be solved. For users who are not familiar with touch panel operations such as smartphones, it is effective to be able to operate the digital television 10 with a virtual television controller in the same manner as a conventional remote control operation.

  The one or more extended function units 44 described above are realized by reading an application program stored in the storage unit 50. The extended function unit 44 may be newly added by downloading an application program via the communication unit 31 (application X, application Y,..., Etc.).

  The display instruction unit 45 transmits an instruction related to the display function of the television signal processing device 2. When an extended function execution screen is generated by each application (extended function unit 44), the display instruction unit 45 outputs the screen (video signal thereof) to the television signal processing device 2 via HDMI. In the example of FIG. 1, the video signal is output via HDMI. However, when each application processes the audio signal, the display instruction unit 45 transmits the audio signal to the TV via HDMI as necessary. You may output to the signal processing apparatus 2. FIG.

  Further, when the display instruction unit 45 directly receives the touch operation type and the coordinate information of the touch position from the input determination unit 41, the display instruction unit 45 stores the touch operation information d3 including the type and coordinate information as necessary. You may supply to the television signal processing apparatus 2 by inter-communication.

(TV signal processing device 2)
As shown in FIG. 1, the television signal processing device 2 includes a television signal processing control unit 60 and a storage unit 70, and can be electrically or communicated with the touch panel 4, the display unit 5, and the input unit 9. It is connected to the.

  The storage unit 70 is a storage device that stores various data used by the television signal processing device 2. In the present embodiment, the storage unit 70 stores at least display mode information 71. Although not shown, the storage unit 70 corresponds to (1) a control program executed by the TV signal processing control unit 60, (2) an OS program, and (3) various TV functions executed by the TV signal processing control unit 60. An application program and (4) various data to be read when the application program is executed are stored.

  The TV signal processing control unit 60 controls the functions of the TV signal processing device 2 in an integrated manner. The TV signal processing control unit 60 includes an instruction analysis unit 61, a TV screen generation unit (screen synthesis unit) 62, an output control unit (output control unit) 63, and a display mode notification unit (notification unit) 64 as functional blocks. Including. Each functional block of the above-described television signal processing control unit 60 includes, for example, a storage device (memory) in which a central processing unit (CPU) or the like is realized by a read only memory (ROM), a non-volatile random access memory (NVRAM), or the like. This can be realized by reading the program stored in the unit 70) into a RAM (random access memory) (not shown) and executing the program.

  The instruction analysis unit 61 analyzes the touch operation information d3 input from the extended function execution device 1, and transmits the contents of the analyzed instruction to each unit related to the instruction. In addition, the instruction analysis unit 61 analyzes an instruction from the user input from the input unit 9 such as a remote controller, and outputs an instruction for generating or updating a TV screen to the TV screen generation unit 62. . In the present embodiment, for example, when an instruction to change to another display mode is received via the input unit 9, the instruction analysis unit 61 supplies the designated display mode to the output control unit 63.

  The television screen generation unit 62 processes the television broadcast signal received via the tuner unit 3 to generate a television screen. Specifically, the television screen generation unit 62 controls various circuits (stream separation unit 21, video decoder unit 23, and graphics processing unit 24) for signal processing related to the video shown in FIG. The above functions are realized. The television screen generation unit 62 also has a function of controlling the graphics processing unit 24 to generate an OSD image and superimposing it on the video obtained by the broadcast signal. Therefore, the television screen may be composed only of the video extracted from the broadcast signal by the video decoder unit 23, or may include the video and the OSD image generated by the graphics processing unit 24. The television screen (video signal) generated by the television screen generation unit 62 is supplied to the scaling unit 27 and the blend unit 28 controlled by the output control unit 63.

  The output control unit 63 processes the video signal related to the screen output from each unit and outputs it to the display unit 5. Specifically, the output unit of the television signal processing device 2, that is, the scaling unit 26, the scaling unit 27, and the blending unit 28 are controlled to realize screen enlargement / reduction, synthesis, and output to the display unit 5.

  When the output control unit 63 changes the display mode, the display mode notification unit 64 notifies the extended function execution device 1 of the changed display mode. Specifically, the display mode notification unit 64 notifies the extended function execution device 1 of the display mode d2 corresponding to the latest screen information output to the display unit 5.

  FIG. 3 is a diagram illustrating an example of video signal processing performed by the output control unit 63. For example, it is assumed that the video signal of the television screen B of the broadcast program processed by the video decoder unit 23 under the control of the television screen generation unit 62 is input to the scaling unit 27. On the other hand, it is assumed that the video signal of the extended function execution screen A supplied from the extended function execution device 1 is input to the scaling unit 26. Then, it is assumed that the mixed display mode is designated from the input unit 9.

  In this case, the output control unit 63 controls the scaling unit 27 in order to display the extended function execution screen A and the television screen B in a mixed manner, so that the television screen B has a predetermined television screen for the mixed display. Necessary reduction processing is executed so as to fit in the area. The output control unit 63 may control the scaling unit 26 as necessary to reduce the extended function execution screen A so as to fit in a predetermined area. Then, the output control unit 63 controls the blending unit 28 to synthesize the TV screen B after expansion / contraction processing and the extended function execution screen A, and creates a mixed screen according to the mixed display mode. When the display mode is changed, the display mode notification unit 64 notifies the extended function execution apparatus 1 of the changed display mode.

[Display mode information]
In the present embodiment, in each of three types of display modes, that is, an extended function execution screen full display mode (extended function execution screen display mode), a TV screen full display mode (TV screen display mode), and a mixed display mode, respectively It is assumed that the size and position of the execution screen and the television screen are defined in advance. This display mode information is stored in the storage unit 70 as display mode information 71 and is referred to by the output control unit 63. In the present embodiment, the extended function control unit 40 and the television signal processing control unit 60 of the extended function execution apparatus 1 communicate via a serial bus, and display common display mode information as display mode information 51 and display mode, respectively. The information 71 is stored in the storage unit 50 and the storage unit 70. Therefore, if the extended function execution device 1 can grasp the display mode that the television signal processing device 2 is currently implementing, the layout of the screen that the television signal processing device 2 actually displays on the display unit 5 and the extended function execution device 1 No wrinkle occurs between the grasped screen information 52.

  4A to 4C are diagrams showing specific examples of the display mode information 51 and the display mode information 71. FIG.

  FIG. 4A shows display mode information defining the layout of the extended function execution screen in the extended function execution screen full display mode. FIG. 4B shows display mode information defining the layout of the television screen in the television screen full display mode. FIG. 4C shows display mode information defining the layout of the extended function execution screen and the television screen in the mixed display mode. The display mode information in the mixed display mode includes at least information that defines the boundary position L1 between the extended function execution screen and the television screen.

  Examples of the display mode information 51 and the display mode information 71 are not limited to the three (a) to (c) in FIG. In particular, a plurality of patterns may be defined in the mixed display mode. For example, there are a pattern where the boundary position L1 is different, a pattern where the boundary position L1 is a position where the display screen of the display unit 5 is vertically divided, and a pattern where the extended function execution screen is superimposed on the lower right of the television screen. May be.

  For example, a unique identifier is assigned to each display mode, and the television signal processing device 2 transmits the identifier indicating one display mode to the extended function execution device 1 to thereby change the display mode being executed. The extended function execution device 1 can be notified.

  The configuration may be such that the user can set or edit the display mode to be learned by the television signal processing device 2 (and the extended function execution device 1). For example, the television signal processing apparatus 2 may display an input screen for setting the display mode on the display unit 5 and allow the user to arbitrarily select the position of the boundary position L1 via the input unit 9. Information on the boundary position L1 selected by the user is received by the television signal processing control unit 60, added to the display mode information 71, and also transmitted to the extended function execution apparatus 1 via inter-CPU communication. The extended function control unit 40 adds the received information on the boundary position L1 to the display mode information 51. In this way, the user can cause the extended function execution device 1 and the television signal processing device 2 to learn the display mode information with one setting.

[Screen information]
5A to 5C are diagrams showing some specific examples of the screen information 52 when the display mode is the mixed display mode.

  The screen information 52 is information indicating the layout of the screen displayed on the display unit 5 by the television signal processing device 2. The screen information 52 includes at least the latest layout information output to the display unit 5. The screen information 52 including the latest layout information is referred to by the input determination unit 41 mainly to determine whether or not the extended function execution screen has been touched.

  The operable area correction unit 42 stores the latest layout information displayed on the display unit 5 as screen information 52 in the storage unit 50 based on the display mode notified from the television signal processing device 2.

  The screen information 52 is not particularly limited, but may be configured with any data structure of (a), (b), and (c) of FIG. In the example shown in FIG. 5A, the screen information 52 includes position information of each of the currently displayed extended function execution screen and the television screen. By referring to the latest screen information 52, the input determination unit 41 can determine which area of the television screen or the extended function execution screen has been operated based on the detected coordinates of the touch position. it can.

  In the example shown in FIG. 5B, a pseudo object that covers the positions of the currently displayed extended function execution screen and the television screen is defined in the screen information 52. The input determination unit 41 determines which area of the television screen or the extended function execution screen is operated depending on whether the coordinates of the detected touch position are included in the object 1 or the object 2. Can do. In the example shown in FIG. 5B, it is determined that the extended function execution screen is operated when the object 1 is touched, and it is determined that the television screen is operated when the object 2 is touched.

  In the example shown in (c) of FIG. 5, the screen information 52 holds position information for each touch-operable object placed on the extended function execution screen by the application being executed. By referring to the latest screen information 52 shown in (c) of FIG. 5, the input determination unit 41 can determine which area has been operated, and is arranged on the extended function execution screen. It is also possible to determine which object is touched.

  In the present embodiment, even if the extended function execution device 1 is touched on the television screen, the extended function execution device 1 does not substantially execute processing corresponding to the touch operation.

  The operable area means an area where any of the extended function units 44 of the extended function execution device 1 executes substantial processing in response to the touch operation when the area is touched. Therefore, in the present embodiment, the extended function execution device 1 must grasp the touch operable area in accordance with the display area of the extended function execution screen.

  Therefore, the operable area correction unit 42 corrects the display area of the extended function execution screen, that is, the touch operable area in the screen information 52 based on the display mode notified from the television signal processing device 2. Thereby, the input determination unit 41 can always accurately determine whether or not the extended function execution screen has been touched based on the latest display mode of the display unit 5.

  The layout of the object in the extended function execution screen is generated and updated by any of the extended function units 44 that generate the extended function execution screen.

[Example of correction of touchable area]
6A to 6D are diagrams showing a specific example of a screen displayed on the display unit 5 and an example of a touch operable region corrected by the operable region correcting unit 42. FIG. In each of the drawings (a) to (d), the upper part shows a screen displayed on the display unit 5, and the lower part shows a touch operable area.

  FIG. 6A shows an example of a screen in the TV screen full display mode and an example of a touch operable area. As shown in the upper part of FIG. 6A, the extended function execution screen is not displayed on the display unit 5 in the television screen full display mode. Therefore, when the television screen full display mode is notified from the television signal processing device 2, the operable area correction unit 42 displays the screen information 52 in the touch operable area as shown in the lower part of FIG. Correct so that there is no.

  FIG. 6B shows an example of the extended function execution screen full display mode and an example of the touch operable area. As shown in the upper part of FIG. 6B, in the extended function execution screen full display mode, the extended function execution screen generated by executing the process by the extended function unit 44 is displayed on the entire screen of the display unit 5. Here, as an example, the website screen generated by the browser application 44a is displayed in full screen. Therefore, when the extended function execution screen full display mode is notified from the television signal processing device 2, the operable area correction unit 42 uses the touch operation in the screen information 52 as shown in the lower part of FIG. Correction is performed so that the possible area extends over the entire touch panel 4.

  FIG. 6C shows an example of a screen in the mixed display mode and an example of a touch operable area. As shown in the upper part of FIG. 6C, in the mixed display mode, the television screen and the extended function execution screen are displayed side by side in the predetermined areas in accordance with the display mode information of FIG. . Therefore, when the mixed display mode is notified from the television signal processing device 2, the operable area correction unit 42, as shown in the lower part of FIG. Correction is made so as to correspond to the display area of the extended function execution screen.

  In the mixed display mode, other patterns other than (c) in FIG. 4 may be defined. For example, the TV screen and the extended function execution screen are arranged side by side so as to be displayed on the display unit 5 with the same size without changing the aspect ratio during full screen display (( d) Top).

  When such a mixed display mode is notified from the television signal processing apparatus 2, as shown in the lower part of FIG. 6D, the operable area correction unit 42 has a touch operable area in the screen information 52. The correction is made so as to correspond to the display area of the extended function execution screen.

[Digital TV processing flow]
FIG. 7 is a flowchart showing the flow of processing of the digital television 10 in the present embodiment.

  First, as an example, when the flow illustrated in FIG. 7 is started, the browser application 44a is activated in the extended function execution device 1, and the television screen is displayed in the television screen full display mode in the television signal processing device 2. It is assumed that it is displayed in full screen. Specifically, a website screen (extended function execution screen d1) is supplied from the extended function execution device 1 to the television signal processing device 2, but the TV screen full display mode is designated via the input unit 9. ing. For this reason, the television signal processing apparatus 2 displays the television screen generated by the television screen generation unit 62 in full screen, and does not display the website screen.

  Here, when the user instructs the television signal processing device 2 to change to another display mode using the input unit 9 such as a remote controller, the instruction analysis unit 61 analyzes the remote control signal and designates it. The display mode d2 is supplied to the output control unit 63 (YES in S101).

  The output control unit 63 controls the scaling units 26 and 27 and the blending unit 28 to enlarge / reduce the TV screen and the extended function execution screen, and change the display mode to the display mode specified in S101 (S102). For example, when an instruction to change from the full TV screen display mode to the mixed display mode is input in S101, the output control unit 63 changes from the display mode in FIG. 4B to the display in FIG. Change to the display mode. As a result, the screen of the display unit 5 is switched from the television screen shown in the upper part of FIG. 6A to the mixed screen shown in the upper part of FIG.

  Subsequently, the display mode notification unit 64 notifies the extended function execution apparatus 1 of the display mode specified in S101 (S103: notification step). The timing at which the display mode notification unit 64 notifies the display mode is preferably the same as or immediately after the television screen is switched to the mixed screen in S102.

  On the other hand, in the extended function execution device 1, when the operable area correction unit 42 receives the display mode notification from the display mode notification unit 64 (YES in S104), the operable area correction unit 42 follows the notified display mode. The screen information 52 is changed. Specifically, the operable area is corrected as shown in the lower part of FIG. 6C from the state shown in the lower part of FIG. 6A so as to coincide with the display area of the extended function execution screen. (S105: area specifying step).

  Thereby, the input determination unit 41 can determine the position of the touch operation based on the operable region that matches the latest display mode of the display unit 5 (S106: input determination step). Therefore, each part of the extended function part 44 can operate | move correctly according to touch operation (extended function execution step).

  According to the above configuration and method, the output control unit 63 of the television signal processing device 2 changes the display mode in accordance with an instruction from the input unit 9, and the display mode notification unit 64 sets the latest display mode after the change. Is sent to the extended function execution device 1.

  When the display mode is notified, the operable area correction unit 42 of the extended function execution device 1 corrects the screen information 52 according to the new display mode. Specifically, the operable area is corrected so as to match the display area of the extended function execution screen specified in the notified display mode.

  Thereby, even if the display mode is changed and the display position of the extended function execution screen is changed, the extended function execution device 1 grasps the display area of the correct extended function execution screen after the change, that is, the operable area. can do. Therefore, the input determination unit 41 can always accurately determine the touch operation.

  Therefore, under the control of the two control units (the extended function control unit 40 and the television signal processing control unit 60), the television screen and the extended function execution screen can be merged to realize a user interface with excellent operability. . Even if the display mode is changed under the control of the TV signal processing control unit 60, the extended function control unit 40 can always correctly grasp the display area of the extended function execution screen, and the user interface can be accurately displayed. It becomes possible to maintain sex.

[Modification]
In the first embodiment, an instruction to change the display mode is exclusively input to the television signal processing device 2 via the input unit 9 and accepted by the television signal processing device 2. However, the configuration is not limited to this, and the digital television 10 may accept an instruction to change the display mode in the extended function execution device 1 via the touch panel 4.

  For example, when the controller application 44b of the extended function unit 44 outputs an extended function execution screen including a software key for instructing to change the display mode, the software key is displayed on the display unit 5 so as to be touch-operable.

  When the software key is touched, the input determination unit 41 supplies the touch position of the touch operation to the controller application 44b. The controller application 44b recognizes which software key is touched from the touch position, specifies which display mode should be changed, and outputs the specified display mode to the display instruction unit 45.

  The display instruction unit 45 transmits the display mode specified by the controller application 44b to the television signal processing device 2. At this time, the operable area correction unit 42 updates the screen information 52 according to the specified display mode.

  The instruction analysis unit 61 of the television signal processing apparatus 2 that has received the display mode designation from the display instruction unit 45 supplies the designated display mode d2 to the output control unit 63. The output control unit 63 changes the screen layout so that the display mode d2 supplied from the instruction analysis unit 61 is set.

  According to the above configuration, the extended function execution device 1 can specify the display mode desired by the user based on the user instruction input via the touch panel 4 and notifies the television signal processing device 2 of this. be able to. The television signal processing apparatus 2 can change the display mode as instructed by the extended function execution apparatus 1.

  Therefore, no discrepancy occurs between the display mode known by the extended function execution device 1 and the display mode actually executed by the television signal processing device 2 in accordance with an instruction from the extended function execution device 1. Therefore, the input determination unit 41 can always accurately determine the touch operation.

  The same applies when the browser application 44a outputs an extended function execution screen including a software key for instructing to change the display mode.

<< Embodiment 2 >>
One embodiment of the present invention will be described below with reference to FIGS.

  In the first embodiment, the television signal processing device 2 is configured to be able to display a television screen processed by the television signal processing device 2 and an extended function execution screen processed by the extended function execution device 1 in a mixed manner. . However, the television signal processing device 2 to which the extended function execution device 1 is attached does not have a function to enlarge / reduce or synthesize the supplied extended function execution screen. Some of them only support two display modes: full screen display or TV screen full screen display.

  In such a digital TV 10, the user cannot perform a touch operation on the extended function execution screen while watching the TV screen. That is, there is a problem that an interface with excellent operability for using the TV function and the extended function cannot be realized.

  In the present embodiment, an interface with excellent operability for using both the TV function and the extended function is realized even in a broadcast receiving apparatus equipped with a TV signal processing apparatus that does not support the mixed display mode. A broadcast receiving apparatus capable of performing the above will be described.

[Hardware configuration]
The digital television 10 of the present embodiment differs from the digital television 10 of the first embodiment shown in FIG. 2 as follows.

  The television signal processing device 2 according to the present embodiment does not include the scaling unit 26 that performs scaling of the extended function execution screen supplied to the television signal processing device 2 via the HDMI separation unit 22. Under the control of the output control unit 63, the blend unit 28 switches which of the extended function execution screen supplied from the HDMI separation unit 22 and the television screen supplied from the scaling unit 27 is output to the display unit 5. Is. In the present embodiment, the blending unit 28 synthesizes the video signal processed by the graphics processing unit 24 and the video signal processed by the scaling unit 27 to generate a television screen. Specifically, the blending unit 28 controls the OSD (On Screen Display) image generated by the graphics processing unit 24 into a video signal such as a broadcast program supplied from the scaling unit 27 under the control of the output control unit 63. A TV screen can be generated by superimposing. However, the blending unit 28 does not have a function of combining and displaying the extended function execution screen and the television screen.

[Functions of digital TV]
FIG. 8 is a functional block diagram showing the main configuration of the digital television 10. The digital television 10 of the present embodiment is different from the digital television 10 of the first embodiment shown in FIG. 1 as follows.

  In the extended function execution device 1, the extended function execution unit 43 further includes an alternative UI selection unit (partial area image designation unit) 46. The alternative UI selection unit 46 selects an alternative UI (User Interface) when the extended function execution screen is not displayed on the display unit 5 in the TV screen full display mode. The alternative UI (partial area image) selected by the alternative UI selection unit 46 is supplied to the display instruction unit 45.

  The display instruction unit 45 transmits to the television signal processing device 2 an alternative UI instruction d4 for instructing the television signal processing device 2 to generate the selected alternative UI. The alternative UI instruction d4 includes information necessary for enabling the television signal processing apparatus 2 to generate an alternative UI. For example, the alternative UI instruction d4 includes information for specifying the alternative UI, a generation procedure of the alternative UI, parts of the alternative UI, and the like.

  When the alternative UI instruction d4 is sent by the display instruction unit 45, the operable area correction unit 42 displays the display area of the touch operable object included in the alternative UI selected by the alternative UI selection unit 46. This is reflected in the screen information 52.

  The substitute UI includes an object that can be displayed on the television screen as a part of the television screen and can be touched, instead of the regular extended function execution screen that is not displayed. The alternative UI is different from the extended function execution screen d1 generated as a video signal by the extended function execution device 1. The alternative UI is generated as one element constituting the television screen in the television signal processing device 2. That is, the graphics processing unit 24 of the television signal processing device 2 generates an alternative UI as an OSD image. As a result, in the TV screen full display mode, it is possible to display the alternative UI that can be touch-operated on the display unit 5 by combining it with the content of the original TV screen. Therefore, even when the television signal processing device 2 does not support the mixed display mode, the user can perform a touch operation on the extended function execution device 1 while viewing the broadcast program on the television screen. Is possible.

  More specifically, when the input determination unit 41 determines that a touch operation is detected on the touch panel 4 in the TV screen full display mode, the alternative UI selection unit 46 executes the extended function execution device 1 in the background at that time. Identify the application that was running. Then, the alternative UI selection unit 46 selects an appropriate alternative UI for touch-operating the application being executed from the alternative UIs stored in the alternative UI storage 53.

  The extended function execution device 1 may further include a document editing application 44c and a health management application 44d as the extended function unit 44.

  The document editing application 44c is an application that provides a user with a UI for editing text by inputting characters and has a function of creating document data.

  The health management application 44d is an application for managing the health of a patient who is admitted to or going to a facility such as a hospital / care facility. It is assumed that the digital television 10 in which the health management application 44d is installed is lent to an individual inpatient and is often installed next to a bed in a hospital room. Or what is installed in the home of the patient who goes to hospital is assumed.

  The patient can use the health management application 44d by touching the digital TV 10 installed beside the bed. As a function of the health management application 44d, for example, a nurse call function is assumed. By arranging a nurse call button on the extended function execution screen and touching this by the patient, it becomes possible to notify the medical staff of his / her abnormality. Furthermore, as a function of the health management application 44d, a function of managing a patient schedule is assumed. The patient can touch the extended function execution screen to display his / her medical treatment schedule on the display unit 5 or to display the medication schedule on the display unit 5.

[Alternative UI]
The alternative UI storage 53 stores alternative UIs corresponding to each of the extended function units 44. FIG. 9 is a diagram illustrating an example of a data structure of the alternative UI storage 53. In FIG. 9, the data structure of the alternative UI storage 53 shown in the table format is merely an example, and the data structure is not intended to be limited to the table format. Hereinafter, the same applies to other figures for explaining the data structure.

  In the present embodiment, the alternative UI storage 53 has a configuration in which an alternative UI is stored in association with an alternative UI identifier for each application installed in the extended function execution apparatus 1.

  The description language for defining the layout of the alternative UI buttons may be any description language that the television signal processing apparatus 2 can understand. For example, BML (Broadcast Markup Language) is used. Thereby, the television signal processing apparatus 2 can understand the arrangement position, shape, color, text displayed on the button, and the like. It should be noted that which event (function) is assigned to which button, the extended function execution device 1 only needs to grasp at least the corresponding application.

  When the alternative UI selection unit 46 receives from the input determination unit 41 the determination result that the touch operation has been performed in the full TV screen display mode, the alternative UI selection unit 46 identifies which application of the extended function unit 44 is being executed at that time. To do. Then, an alternative UI corresponding to the identified application is selected. For example, when the application being executed is the browser application 44a, the alternative UI selection unit 46 selects an alternative UI whose alternative UI identifier is “U001”.

  In this embodiment, the display instruction unit 45 notifies the television signal processing device 2 of the alternative UI identifier selected by the alternative UI selection unit 46 as the alternative UI instruction d4.

  In the present embodiment, an alternative UI storage 73 is stored in the storage unit 70 of the television signal processing device 2. The alternative UI storage 73 stores the same information as the alternative UI storage 53 as shown in FIG. Therefore, the television signal processing apparatus 2 can generate an alternative UI as instructed by the extended function execution apparatus 1 only by designating the alternative UI identifier.

  Specifically, when the instruction analysis unit 61 receives an alternative UI identifier as the alternative UI instruction d4 from the display instruction unit 45, the instruction analysis unit 61 supplies the alternative UI identifier to the television screen generation unit 62.

  The TV screen generation unit 62 refers to the alternative UI storage 73 and specifies an alternative UI to be included in the TV screen based on the supplied alternative UI identifier. Then, the graphics processing unit 24 is controlled so as to generate the alternative UI. The graphics processing unit 24 generates the specified alternative UI as an OSD image under the control of the television screen generation unit 62, and outputs the video signal to the blending unit 28.

  The output control unit 63 controls the scaling unit 27 and the blend unit 28 to output a video signal (original television screen) output from the scaling unit 27 and a video signal (OSD image) output from the graphics processing unit 24. And synthesize. The original television screen is, for example, a broadcast program. As a synthesis method, the output control unit 63 may superimpose the broadcast program on the entire screen and superimpose it on the broadcast program to superimpose an alternative UI that is an OSD image. Alternatively, the output control unit 63 may The broadcast program area may be reduced so that it does not overlap with the button of the alternative UI, and the broadcast program and the alternative UI may be arranged side by side. In any case, the video signal of the television screen including the broadcast program and the alternative UI is output from the blend unit 28 to the display unit 5 under the control of the output control unit 63.

[Synthesis example of alternative UI]
FIG. 10A is a transition diagram illustrating a specific example of a screen displayed on the display unit 5 and an example of a screen transition associated with the occurrence of an event. FIG. 10B is a diagram illustrating another specific example of the television screen on which the alternative UI is synthesized among the screens displayed on the display unit 5.

  In FIG. 10A, the upper diagram shows the screen of the display unit 5 in the TV screen full display mode. When the TV screen is touched (for example, tapped) in the TV screen full display mode, the alternative UI selection unit 46 selects an alternative UI corresponding to the application (for example, the browser application 44a) being executed at this time. An alternative UI instruction d4 for instructing display of the selected alternative UI is notified to the television signal processing apparatus 2 via the display instruction unit 45.

  The TV screen generation unit 62 of the TV signal processing device 2 generates an alternative UI specified by the alternative UI instruction d4, and the output control unit 63 combines the alternative UI with the original TV screen (broadcast program). Thus, the television screen combined with the alternative UI is displayed on the display unit 5 as shown in the middle diagram of FIG. As shown in FIG. 10B, the output control unit 63 reduces the broadcast program display area and changes the position of the display area so that the original broadcast program and the alternative UI do not overlap. Also good.

  When any button (for example, “Home” button) is tapped in the state shown in the middle diagram of FIG. 10A, the input determination unit 41 determines that the alternative UI has been touched and performs a touch operation. Information is transmitted to a running application (in the above example, the browser application 44a). The browser application 44a recognizes that the “home” button is touched from the touch position included in the touch operation information, and executes the function assigned to the button. For example, the browser application 44a accesses an external server based on a preset URL, downloads a home page, and generates a website screen of the home page.

  The website screen as the extended function execution screen d1 generated by the browser application 44a is supplied to the television signal processing device 2. The output control unit 63 of the television signal processing device 2 displays the website screen on the display unit 5 in the extended function execution screen full display mode, as shown in the lower diagram of FIG.

  Note that the input determination unit 41 of the extended function execution apparatus 1 refers to the screen information 52 indicating the latest screen layout displayed on the display unit 5 to determine whether the current display mode is the full TV screen display mode. It is possible to grasp whether the extended function execution screen is in full display mode. In the present embodiment, a method for always maintaining the screen information 52 in the latest state is not particularly limited. For example, the following techniques can be employed.

  First, it is conceivable to employ the technique of the first embodiment. That is, the television signal processing device 2 includes a display mode notification unit 64. The display mode notification unit 64 notifies the extended function execution device 1 of the latest display mode d2 every time the output control unit 63 switches the display mode. The extended function execution device 1 includes an operable area correction unit 42. When receiving the notification of the display mode d2 from the television signal processing device 2, the operable area correction unit 42 updates the screen information 52 based on the display mode.

  Alternatively, the input determination unit 41 of the extended function execution device 1 can be configured as follows. The input determination unit 41 makes an inquiry about the latest display mode to the display mode notification unit 64 every time a touch operation is detected. The display mode notification unit 64 of the television signal processing device 2 returns the current display mode d2 to the extended function execution device 1 as a response to the inquiry. When receiving the notification of the display mode d2 from the television signal processing device 2, the operable area correction unit 42 updates the screen information 52 based on the display mode.

  According to any one of the configurations described above, the input determination unit 41 can refer to the screen information 52 that is always maintained in the latest state, and when a touch operation is detected in the TV screen full display mode, It can be accurately determined that the screen has been touched at any time.

[Digital TV processing flow]
Next, the processing flow of the digital television 10 will be described using the above specific example again. FIG. 11 is a flowchart showing a processing flow of the digital television 10 in the present embodiment.

  First, at the time when the flow shown in FIG. 11 is started, as shown in the upper diagram of FIG. 10A, the television signal processing device 2 displays the television screen in full screen in the television screen full display mode. ing. Here, in the extended function execution device 1, it is assumed that the browser application 44a is executed in the background.

  It is assumed that the user taps the touch panel 4 in the TV screen full display mode. When the touch operation is thus detected on the touch panel 4, the input determination unit 41 determines that the television screen has been tapped (YES in S201, NO in S202 and S203). Then, the input determination unit 41 notifies the alternative UI selection unit 46 of the determination result that the television screen has been tapped. In this case, the input determination unit 41 does not supply touch operation information to the extended function unit 44. Thereby, the malfunction by the extended function part 44 is avoided.

  The input determination unit 41 determines that a touch operation has been detected in the extended function execution screen full display mode (YES in S202), or has determined that the alternative UI has been touched even in the TV screen full display mode. In the case (YES in S203), the touch operation information is supplied to any application being executed.

  When the alternative UI selection unit 46 receives the determination result from the input determination unit 41, first, the alternative UI selection unit 46 identifies an application being executed (S204). Then, the alternative UI selection unit 46 selects an alternative UI corresponding to the identified application as an alternative UI to be displayed on the display unit 5 (S205). In the above example, the alternative UI selection unit 46 determines that the browser application 44a is being executed in the background, refers to the alternative UI storage 53, and selects the alternative UI having the alternative UI identifier “U001”. .

  The display instruction unit 45 notifies the television signal processing device 2 of an alternative UI instruction d4 for instructing the television signal processing device 2 to display the selected alternative UI (S206). In the present embodiment, for example, the alternative UI instruction d4 includes at least an alternative UI identifier “U001”. Here, the operable area correction unit 42 updates the screen information 52 based on the alternative UI selected in S205 (S207). Specifically, the display area of the touchable object included in the alternative UI is added to the display area of the television screen.

  On the other hand, when the instruction analysis unit 61 of the television signal processing apparatus 2 receives the alternative UI instruction d4 (YES in S208), the alternative UI identifier included in the alternative UI instruction d4 is supplied to the television screen generation unit 62.

  The television screen generation unit 62 refers to the alternative UI storage 73 and reads out the alternative UI associated with the alternative UI identifier “U001”. Then, an OSD image of this alternative UI is generated (S209). Subsequently, the output control unit 63 combines the OSD image of the alternative UI with the original broadcast program (S210). For example, as shown in the middle diagram of FIG. 10A, the OSD image of the alternative UI is superimposed on the broadcast program. Alternatively, as illustrated in FIG. 10B, the output control unit 63 reduces the display area of the broadcast program and changes the display area so that the broadcast program and the alternative UI do not overlap with each other. The alternative UI may be arranged side by side. Then, the television screen combined with the alternative UI is displayed on the display unit 5 (S211).

  The operable area correction unit 42 most preferably updates the screen information 52 at the time of S211, but the screen information 52 may be updated immediately before or after S211.

  When the touch panel 4 receives a touch operation after the alternative UI is displayed on the display unit 5, the input determination unit 41 refers to the updated screen information 52, so that even in the TV screen full display mode. Then, it can be determined whether or not an object that can be touched is touched (S203).

  For example, as illustrated in FIG. 10A, when the “home” button is touched (YES in S203), the input determination unit 41 determines that the alternative UI has been touched, and executes the touch operation information. To the middle application (in this case, the browser application 44a). Then, the browser application 44a recognizes that the “home” button is touched according to the touch operation information, and executes the function assigned to the “home” button (S212). The extended function execution screen d1 reflecting the execution result is supplied to the television signal processing apparatus 2 via the display instruction unit 45.

  When the alternative function execution screen d1 is newly received after the alternative UI is displayed, the two-output control unit 63 of the television signal processing device is generated based on the operation of the alternative UI. You may judge that it is a screen. Then, the output control unit 63 may switch the display mode from the television screen full display mode to the extended function execution screen full display mode and display the extended function execution screen d1 on the display unit 5 in full screen (S213). . Or you may operate | move according to the instruction | indication of the user input via the input part 9 (S213).

  As described above, according to the above configuration and method, the digital television 10 is executed in the background while displaying the television screen in full screen, even if the television signal processing device 2 is not compatible with the mixed display mode. An alternative UI (OSD image) for touching the extended function execution screen can also be displayed. Therefore, there is an effect that an interface excellent in operability for using the television function and the extended function can be realized.

[Modification]
In the second embodiment, in order to easily use or maintain the alternative UI in the alternative UI storage 53 and the alternative UI storage 73, or to reduce the capacity of the alternative UI storage 53 and the alternative UI storage 73 The alternative UI storage 53 may have a different data structure.

  Specifically, templates are defined for highly versatile elements that are common to a plurality of applications among the elements that constitute the alternative UI. Then, the display instruction unit 45 notifies the television signal processing device 2 of the elements that are different for each application as the alternative UI instruction d4.

  FIG. 12 is a diagram illustrating another example of the data structure of the alternative UI storage 53. In this modification, the alternative UI storage 53 includes a table for storing a template of the alternative UI and a table for storing different elements for each application.

  FIG. 12A is a table for storing templates. In this table, several templates are stored in association with template identifiers. The template defines, for example, the layout of objects (buttons) that can be touched. A common template may be adopted for a plurality of applications.

  The character string that describes the function assigned to each button arranged in the template differs for each application. Therefore, the element of the character string is stored in a separate table for each application.

  FIG. 12B is a table that stores character strings to be assigned to buttons. In this table, for each application, a template identifier of a template corresponding to the application and a character string element assigned to each button arranged in the template are stored in association with each other.

  For example, according to the column of “model identifier”, the template of the template identifier “T001” is adopted for the browser application 44a. When the above template is used for the browser application 44a in the “character string” column, the character string “home” is displayed for the button A, the character string “previous page” is displayed for the button B, and the button C is displayed. Is provided with a character string “next page” and a button D with a character string “END”.

  When the alternative UI selection unit 46 specifies that the application being executed when the TV screen is touched is the browser application 44a, the alternative UI selection unit 46 refers to the alternative UI storage 53 shown in FIG. 12 and is suitable for the browser application 44a. In this way, the template (“T001”) and the character string element of each button can be selected.

  When the alternative UI selection unit 46 selects a template and a character string, the display instruction unit 45 generates an alternative UI instruction d4 including these and notifies the television signal processing device 2 of the alternative UI instruction d4. FIG. 13 is a diagram illustrating a data structure of the alternative UI instruction d4 in the present modification. As shown in FIG. 13, the alternative UI instruction d4 includes at least the template identifier of the template selected by the alternative UI selection unit 46 and the character string element selected by the alternative UI selection unit 46. .

  On the other hand, the substitute UI storage 73 referred to by the television signal processing apparatus 2 only needs to store the template table shown in FIG. Based on the notified template identifier, the TV screen generation unit 62 reads the corresponding template from the alternative UI storage 73, and combines the notified character string of each button with the read button of each template. Can generate an alternative UI. When the alternative UI instruction d4 shown in FIG. 13 is notified, the television screen generating unit 62 can generate the same alternative UI as the alternative UI identifier “U001” shown in FIG. As a result, the output control unit 63 can display a composite screen as shown in the middle diagram of FIG. 10A or the composite screen of FIG.

  According to the above configuration, the amount of information stored in the alternative UI storage 73 can be reduced compared to the alternative UI storage 73 shown in FIG. There is also an advantage that the maintenance of the alternative UI becomes easy. For example, when it is desired to change the button layout of the alternative UI of the browser application 44a, in the example shown in FIG. 9, the alternative UI of the browser application 44a stored in the alternative UI storage 53 and the alternative UI storage 73 must be recreated. I must. On the other hand, in this modified example, it is only necessary to change the template identifier associated with the application in the table of FIG. 12B stored in the alternative UI storage 53. Even if the number of buttons changes, you only need to update the elements of the string as needed. No maintenance is required for the alternative UI storage 73 of the TV signal processing device 2. Thus, according to the present modification, it is possible to greatly reduce the trouble of updating the alternative UI.

[Example of software implementation]
The control blocks of the extended function execution device 1 and the television signal processing device 2 (particularly, the respective portions of the extended function control unit 40 of the extended function execution device 1 and the respective portions of the television signal processing control unit 60 of the television signal processing device 2) It may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, each of the extended function execution device 1 and the television signal processing device 2 is capable of reading a program instruction that is software that realizes each function, and the program and various data can be read by a computer (or CPU). A ROM (Read Only Memory) or a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) in which the above program is expanded, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

Input control is performed by the extended function execution device, and output control based on the input control is performed by the television signal processing device. Specifically, the output control means of the television signal processing device outputs a television screen including a video signal obtained by processing the television broadcast signal, and the extension output as a result of the extension function execution device executing the extension function. At least one of the extended function execution screens including the functional video signal is output to the display unit of the broadcast receiving apparatus. The notification means notifies the extended function execution device of at least the display area of the extended function execution screen among the television screen and the extended function execution screen displayed by the output control means. When the display area of the extended function execution screen is notified, the area specifying unit of the extended function execution apparatus specifies an operable area for receiving a touch operation on the extended function execution screen according to the notification. Then, the input determination means of the extended function execution device determines whether the touch-operated position is on the television screen based on the position information detected by the touch panel formed integrally with the display unit, or on the extended function execution screen. Determine if there is.

  Thereby, even if the display position of the extended function execution screen is changed by the television signal processing device, the extended function execution device can grasp the correct display area of the extended function execution screen after the change, that is, the operable area. Therefore, the input determination unit can always accurately determine the touch operation on the extended function execution screen. Therefore, there is an effect that it is possible to realize a broadcast receiving apparatus having an interface with excellent operability for using the TV function and the extended function.
