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 a high degree of interactivity and functions that can meet the demands of free and diverse use, like 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 ideas have been made in the past in order to incorporate these merits into the television.

  For example, Patent Document 1 discloses a digital broadcast receiving apparatus that has the convenience of being intuitively operated by realizing an input device for remotely operating a television, that is, a so-called remote controller using a touch panel.

  Patent Document 2 discloses an image display device that realizes the use of 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.

  An input signal related to the touch operation detected on the touch panel 4 is acquired by the extended function execution device 1, and processing corresponding to the input signal is executed in the extended function execution device 1. As a result, when there is something to be executed by the television signal processing device 2, the extended function execution device 1 transmits an instruction to the television signal processing device 2. In particular, the television signal processing device 2 includes a television screen including a video signal obtained by the television signal processing device 2 processing a television broadcast signal according to an instruction from the extended function execution device 1, and the extended function execution device. It is possible to synthesize the extended function execution screen including the extended function video signal output as a result of executing the extended function 1 and to output both of the screens to the display unit 5 in a mixed manner.

  That is, in this embodiment, the television signal processing device 2 is configured to have a function of synthesizing the television screen processed by the device itself and the extended function execution screen processed by the extended function execution device. The television signal processing device 2 includes the touch panel 4 but does not have a function of performing input control. Instead, the television signal processing device 2 is controlled by an external instruction from the extended function execution device 1 that performs input control of the touch panel 4.

Have The signal processing is executed by the various circuits described above.

  More specifically, the stream separation unit 21 converts the transport stream (TS) extracted from the tuner unit 3 into a video signal, an audio signal, and a data signal (caption information or BML (Broadcast Markup Language) information). ) Is stream-separated (DEMUX). The video decoder unit 23 decodes the separated video signal. The graphics processing unit 24 converts the separated data signal into graphics. The audio decoder unit 25 decodes the separated audio signal. The scaling unit 27 adjusts the size of the video signal in accordance with the designated display mode. The scaled video signal and the graphic converted by the graphics processing unit 24 are supplied to the blending unit 28. The audio signal decoded by the audio decoder unit 25 is supplied to the mixing unit 29. As described above, the system signals of the television signal processing apparatus 2 are processed.

  On the other hand, the HDMI signal including the video signal and the audio signal output from the extended function execution device 1 is first received by the HDMI separation unit 22. The HDMI separation unit 22 separates the HDMI signal into a video signal and an audio signal. The scaling unit 26 adjusts the size of the video signal in accordance with the designated display mode. The scaled video signal is supplied to the blend unit 28. The separated audio signal is supplied to the mixing unit 29. As described above, the system signal of the extended function execution apparatus 1 is processed.

  Finally, the blending unit 28 performs composition by arranging each video signal in accordance with the designated display mode. The display mode designated via the serial bus is received by the CPU of the television signal processing apparatus 2 (not shown), and the output units (scaling unit 26, scaling unit 27, and blend unit 28) are controlled according to the display mode. Thereby, the synthesis in accordance with the designated display mode is executed.

  The mixing unit 29 selectively outputs the audio signal decoded by the audio decoder unit 25 or the audio signal separated by the HDMI separation unit 22. Which one to select is instructed from the extended function execution device 1 through the serial bus.

  When a command is transmitted from the extended function execution device 1 via the serial bus, the CPU of the television signal processing device 2 controls each unit (for example, the tuner unit 3) of the digital television 10 according to the command. Then, the above command is executed (for example, channel switching).

  As described above, according to the configuration of the digital television 10 of the present invention, the conventional television broadcast screen (hereinafter referred to as the television screen) processed by the television signal processing device 2 and the extended function execution device are displayed on the display unit 5 of the digital television 10.

[Functions of digital TV]
FIG. 1 is a functional block diagram showing a main configuration of the digital television 10 (broadcast receiving apparatus). 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 a service server that provides a schedule management service that manages a user's schedule and notifies the schedule on time is connected to the Internet. The communication unit 31 transmits a user's schedule to the service server via the Internet, or receives a schedule notification from the service server at a preset time. In another example, the communication unit 31 may access a video posting site or a pay program providing site and download a video selected 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, screen information 52, and event-instruction correspondence information 53. 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. And (4) various data to be read when the application program is executed is stored.

  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, as functional blocks, an input determination unit 41 (input determination unit), a direct UI unit 42 (television UI unit), a command generation unit 45 (command generation unit), and a display instruction unit 46 (instruction Means) and at least one extended function unit 47 (extended function means) represented by the controller application 43, the schedule application 44, and the like. 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.

  Each function of the extended function control unit 40 is roughly classified into an input determination unit 41 and a UI processing unit 48 (UI processing means). The former processes an input signal generated by a touch operation on the touch panel 4 to determine what touch operation has been performed (generates touch operation information indicating what touch operation has been performed). ) The latter performs processing according to the determination result of the input determination unit 41, that is, touch operation information.

  More specifically, the UI processing unit 48 includes a direct UI unit 42, one or more extended function units 47 (for example, a controller application 43 and a schedule application 44), a command generation unit 45, and a display instruction unit 46. Including.

  The input determination unit 41 identifies the touch position of the indicator based on the detection signal from the touch panel 4 and determines which of the extended function execution screen and the television screen has been operated. Further, the input determination unit 41 acquires a set of touch position points (trajectory of movement of the indicator) in time series, and determines 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.

  If the input determination unit 41 determines that the television screen has been touched, it transmits the determination result to the direct UI unit 42. If the input determination unit 41 determines that the extended function execution screen has been touched, the input determination unit 41 To the extended function unit 47.

  The direct UI (User Interface) unit 42 realizes a user interface for directly operating the television screen via the touch panel 4. The direct UI unit 42 determines an operation related to a television function to be executed by the digital television 10 (the television signal processing device 2) according to what touch operation is performed on the television screen. Specifically, the operation to be executed by the digital television 10 includes switching channels. Further, the direct UI unit 42 may determine to change the display mode from full screen display to mixed display (or vice versa). The direct UI unit 42 outputs the operation of the digital television 10 determined according to the touch operation and the display mode to be changed to the command generation unit 45 and the display instruction unit 46, respectively. The direct UI unit 42 may determine both the operation and the display mode of the digital television 10 according to one touch operation, or may determine any one of them.

  Thus, the user can use the TV function of the digital TV 10 by operating the TV screen by an intuitive operation similar to that of a smartphone or the like.

  The extended function unit 47 implements various extended functions that the extended function execution device 1 has. In the present embodiment, a controller application 43 and a schedule application 44 are listed as examples of the extended function unit 47.

  The controller application 43 implements a conventional infrared TV remote controller with software keys and provides it to the user. The controller application 43 generates a software key obtained by virtualizing the TV remote control as an extended function execution screen. The generated extended function execution screen is displayed on the display unit 5 of the digital television 10 together with the television screen showing the broadcast video (for example, the screen 82 in FIG. 7). In addition, the controller application 43 determines that the digital television 10 is to change the display mode or performs other operations (for example, channel switching) in response to a user's touch operation. Also good. Thereby, the user touches the key displayed on the extended function execution screen to instruct the digital television 10 to switch to a desired channel, instruct to display / hide the electronic program guide, It is possible to adjust the volume.

  The controller application 43 outputs the operation of the digital television 10 and the display mode to be changed, which are determined according to the touch operation, to the command generation unit 45 and the display instruction unit 46, respectively. In addition, the controller application 43 outputs the extended function execution screen generated according to the touch operation to the display instruction unit 46. It is not necessary for the controller application 43 to output all of the operation, display mode, and extended function execution screen of the digital television 10 in response to one touch operation. If the controller application 43 outputs at least one of them as necessary, Good.

  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, providing a virtual controller together with the television screen on the extended function execution screen is meaningful because such inconvenience can be solved. For users who are not familiar with touch panel operations such as smartphones, it is meaningful that the virtual television controller can operate the digital television 10 in the same manner as a conventional remote control operation.

  The schedule application 44 provides the user with a function for managing the user's schedule. The schedule application 44 notifies the user of a schedule registered in advance on time. At the registered time, the schedule application 44 generates a screen for notifying a schedule to be executed at that time as an extended function execution screen. The schedule application 44 operates the television so that the extended function execution screen is preferentially displayed regardless of the operation state or display mode of the digital television 10 immediately before the scheduled time. Is preferably determined. This makes it possible to notify the user of the schedule with certainty. For example, when the schedule application 44 is an application for managing a patient's medication schedule, the type of medicine to be taken, the amount to be taken, and the like can be notified in accordance with the time of taking. Alternatively, in an accommodation facility or the like, the schedule application 44 can be used as an application for managing a guest's schedule. In this case, the schedule application 44 can notify the wake-up time or the check-out time.

  When the schedule application 44 detects an event indicating that the registered time has come, the schedule application 44 outputs the display mode to be changed and the extended function execution screen generated to notify the schedule to the display instruction unit 46. The registration information related to the user's schedule may be managed in the extended function execution apparatus 1 or may be managed by an external service server connected via the Internet.

  In the former case, the schedule application 44 detects the event by a timer (not shown) provided in the extended function execution device 1. In the latter case, the schedule application 44 detects the event when the communication unit 31 receives the notification of the schedule from the service server on time.

  Further, preferably, the schedule application 44 is executed by each application that has been executed until immediately before the touch panel 4 is input to the effect that the user has executed the schedule in order to ensure that the user has executed the notified schedule. Can be locked to prevent it.

  For example, the schedule application 44 provides an “executed” button in the extended function execution screen. Then, the touch operation on the screen of the application that has been executed until immediately before the button is tapped after the extended function execution screen is displayed is disabled.

  More specifically, when the direct UI unit 42 is being executed immediately before the schedule application 44 and the TV screen is displayed on the display unit 5, even if a touch operation on the TV screen is performed, The direct UI unit 42 is instructed not to accept it. Alternatively, if the controller application 43 is being executed immediately before and the controller software key is displayed as the extended function execution screen, the extended function execution screen is displayed so as to replace it with the schedule notification screen. The data is output to the television signal processing device 2 via the instruction unit 46.

  When it is detected that the “executed” button has been tapped, the schedule application 44 instructs the locked application to return so as to return to the previous display state.

  The direct UI unit 42 and the one or more extended function units 47 are realized by reading an application program stored in the storage unit 50. The extended function unit 47 may be newly added by downloading an application program via the communication unit 31 (application X, application Y,...).

  In order to cause the television signal processing device 2 to execute the operation of the digital television 10 determined by each application, the command generation unit 45 generates a command statement that commands the operation as a command that the television signal processing device 2 can interpret. Is. The command generated by the command generation unit 45 is transmitted to the television signal processing device 2 via the display instruction unit 46.

  The display instruction unit 46 transmits instructions to the television signal processing device 2. When the command generation unit 45 generates a command, the display instruction unit 46 outputs the command to the television signal processing device 2 via a serial bus for inter-CPU communication. When the display mode is determined by each application, the display instruction unit 46 outputs the display mode to the television signal processing device 2 via the serial bus. When the extended function execution screen is generated by each application, the display instruction unit 46 outputs the screen (the 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 as necessary, the display instruction unit 46 converts the audio signal into a television signal via HDMI. You may output to the processing apparatus 2. FIG.

(TV signal processing device 2)
As shown in FIG. 1, the television signal processing device 2 includes a touch panel 4, a display unit 5, a television signal processing control unit 60, and a storage unit 70.

  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 television signal processing control unit 60 includes an instruction analysis unit 61, a command execution unit 62, and an output control unit 63 (output control means) as functional blocks. 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 instruction transmitted from the extended function execution apparatus 1 and transmits the contents of the analyzed instruction to each unit related to the instruction. Specifically, when a command is received from the display instruction unit 46, the instruction analysis unit 61 expands and supplies the command to a state in which the command execution unit 62 can read the command. When the display mode is received from the display instruction unit 46, the instruction analysis unit 61 supplies the display mode to the output control unit 63.

  The command execution unit 62 executes the television function according to the command transmitted from the display instruction unit 46. The command execution unit 62 transmits the command execution result to the output control unit 63 or to another command execution unit (not shown) depending on circumstances.

  A specific example of the command execution unit 62 is a channel selection unit. The channel selection unit controls the tuner unit 3 to execute the channel switching function. The video signal newly obtained by the channel selection unit switching the channel is processed by various circuits for signal processing shown in FIG. 2 and the scaling unit 27 controlled by the output control unit 63 as described above. And supplied to the blending unit 28.

  The output control unit 63 processes the video signal 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 the enlargement / reduction, synthesis, and output to the display unit 5 of the video signal. .

  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 is input to the scaling unit 27. On the other hand, it is assumed that 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 extended function execution device 1 instructs a display mode for displaying these two screens in a mixed manner.

  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 together, so that the television screen B fits in a predetermined television screen area. Thus, the necessary reduction processing is executed. 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 blend unit 28 to synthesize the TV screen B and the extended function execution screen A after the enlargement / reduction processing, and create a mixed screen according to the mixed display mode.

  According to the above configuration, the television signal processing device 2 responds to an instruction from the extended function execution device 1 according to reception of at least one of the command d1, the display mode d2, and the extended function execution screen d3. A TV function can be realized. Specifically, the command execution unit 62 executes the command according to the command d1, the output control unit 63 changes the display mode according to the display mode d2, or the output control unit 63 displays the extended function execution screen d3. Is output to the display unit 5.

  Thus, the extended function execution device 1 can respond to the user operation received by the extended function execution device 1 via the touch panel 4 and reflect the result on the display unit 5 of the television signal processing device 2. It is also possible to make the television signal processing device 2 respond. As a result, it is possible to realize a user interface with a sense of unity by taking advantage of the fact that two screens are mixedly displayed. In addition, by adopting a configuration in which the extended function execution device 1 performs input control of the touch panel 4, an intuitive and arbitrary operation can be performed using the touch panel 4 without increasing the processing load of the television signal processing device 2. A user interface can be realized on the digital television 10.

[Display mode information]
In the present embodiment, the size and position of the television screen B and the extended function execution screen A are defined in advance in the mixed display mode and other display modes, respectively. 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. For this reason, a wrinkle does not arise between the display mode instructed by the extended function execution device 1 and the result of actual display based on the display mode instructed by the television signal processing device 2.

  (A)-(c) of FIG. 4 is a figure which shows a specific example of the display mode information 51 (71).

  FIG. 4A shows display mode information that defines the layout of a mode for displaying the extended function execution screen on the entire screen of the display unit 5 (hereinafter referred to as an extended function execution screen full display mode). FIG. 4B shows display mode information that defines the layout of a mode in which a television screen is displayed on the entire screen of the display unit 5 (hereinafter referred to as a “TV screen full display mode”). FIG. 4C shows display mode information that defines a layout of a mode in which an extended function execution screen and a television screen are mixedly displayed (hereinafter, mixed screen display mode). The display mode information in the mixed screen display mode includes at least information defining the boundary position L1 between the extended function execution screen and the television screen.

  The example of the display mode information 51 (71) is not limited to the three (a) to (c) in FIG. In particular, in the mixed screen display mode, a plurality of patterns may be further defined. 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 given to each display mode, and the extended function execution device 1 transmits the identifier indicating one display mode to the television signal processing device 2 to thereby select a display mode to be executed. This can be specified for the television signal processing device 2.

  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 using the touch panel 4. Information on the boundary position L1 selected by the user is received by the extended function control unit 40, added to the display mode information 51, and transmitted to the television signal processing device 2 via the display instruction unit 46. The television signal processing control unit 60 adds the received information on the boundary position L1 to the display mode information 71. 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 illustrating some specific examples of the screen information 52. FIG.

  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. In the present embodiment, the screen information 52 may further include layout information immediately before the latest layout. Thereby, each part of the extended function execution device 1 specifies what instruction should be transmitted to the television signal processing device 2 when it is desired to return the television signal processing device 2 to the previous display state. Is possible.

  The screen information 52 including the latest layout information is referred to by the input determination unit 41 to mainly determine which screen has been touched.

  The display instruction unit 46 stores the latest layout information to be displayed on the display unit 5 in the storage unit 50 as the screen information 52 based on the content instructed to the television signal processing device 2. In the present embodiment, the display instruction unit 46 stores the previous layout information in the storage unit 50 as the screen information 52 together with the latest layout information without deleting the previous layout information.

  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 illustrated in FIG. 5A, the screen information 52 includes the positions 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 FIG. 5C, the input determination unit 41 can determine which area has been operated and also determine which object has been touched. can do.

[Event-instruction correspondence information]
6A to 6C are diagrams showing a specific example of the event-instruction correspondence information 53 in a table format. In FIGS. 6A to 6C, the event-instruction correspondence information 53 is shown as a data structure in the form of a table, and is not intended to limit the data structure. The event-instruction correspondence information 53 is referred to in order to determine the contents to be executed by the digital television 10 in response to the event being executed when the event occurs in the extended function execution device 1. Therefore, in the event-instruction correspondence information 53, an assumed event is associated with the content to be executed by the digital television 10 at that time. FIG. 6A shows an example of event-instruction correspondence information 53 referred to by the direct UI unit 42. FIG. 6B shows an example of event-instruction correspondence information 53 referred to by the controller application 43. FIG. 6C shows an example of event-instruction correspondence information 53 referred to by the schedule application 44. Each application can determine what to do with the television when an event occurs by referring to each table.

  In FIG. 6A, a touch operation on the TV screen on the touch panel 4 is assumed as an event, and each event includes an area in which the touch operation is performed, a type of the touch operation, and, in some cases, a display mode at that time. And specified by. The content to be executed by the digital television 10 includes at least one of “operation” and “display mode”. The direct UI unit 42 refers to this table, and at least one of the operation to be executed by the digital television 10 and the display mode to be changed according to which touch operation is performed on the television screen in which display mode. One can decide.

  In FIG. 6B, a touch operation on the extended function execution screen is assumed as an event, and each event is specified by the touched region, an object in the region, and in some cases, the type of the touch operation. Is done. The content to be executed by the digital television 10 includes at least one of “operation” and “display mode”. The controller application 43 determines at least one of an operation to be executed by the digital television 10 and a display mode to be changed according to which key is touched among software keys (objects) displayed as the extended function execution screen. can do.

  In FIG. 6C, external processing and touch operation on the extended function execution screen are assumed as events. The external processing includes, for example, that the timer has detected on-time, and that the communication unit 31 has received some information from the external device. The touch operation event is specified by the touch-operated area and the object in the area, and, in some cases, the type of the touch operation. The content to be executed by the digital television 10 includes at least one of “operation” and “display mode”. The schedule application 44 can determine at least one of an operation to be executed by the digital television 10 and a display mode to be changed according to the event that has occurred.

  Each table in FIG. 6 is a process of an application when each application executes a process triggered by the occurrence of an event, and accordingly, the result of the process needs to be reflected on the digital television 10. Is described. Therefore, each table in FIG. 6 does not cover everything that an application executes. The application may also execute processing that is not described in the table, that is, processing that should be executed by the extended function execution device, with the occurrence of the event as a trigger. For example, a process for newly generating an extended function execution screen or a process for restricting the operation of another application.

  More specifically, when the event 1 occurs, the direct UI unit 42 can start the controller application 43 that generates the extended function execution screen of the controller key. In this case, the direct UI unit 42 outputs the mixed screen display mode to the display instruction unit 46, while the controller application 43 outputs the controller key extended function execution screen to the display instruction unit 46.

  In another example, when the event 8 or the event 9 occurs, the schedule application 44 stores the latest screen information so far as the previous screen information in the storage unit 50 so that it can be referred to later. Then, the schedule application 44 outputs an extended function execution screen as a schedule notification screen to the display instruction unit 46. The schedule application 44 can lock the function of the direct UI unit 42 from when the notification screen is displayed on the display unit 5 until the “executed” button included in the notification screen is tapped. During this time, even if any touch operation is performed on the television screen, the direct UI unit 42 does not determine the content to be executed by the television and outputs nothing to the display instruction unit 46. Thereafter, when the event 10 occurs, the schedule application 44 determines to return to the previously stored screen information. Specifically, when returning to the operation of the immediately preceding digital television 10, returning to the immediately preceding display mode, or when another application is executing the process immediately before, the extended function execution screen of the other application Decide to return to. The schedule application 44 outputs the previous command and the display mode to the display instruction unit 46 and releases the lock on the direct UI unit 42. If there is another application being executed immediately before, the application is instructed to resume the process. Thereby, according to at least any one of the command, the display mode, and the extended function execution screen transmitted from the display instruction unit 46, the television signal processing apparatus 2 is configured so that the “executed” button is tapped. It is possible to return to the previous state.

[Screen example]
FIG. 7 is a transition diagram showing a specific example of a screen displayed on the display unit 5 and an example of screen transition accompanying event occurrence.

  The screen 80 is a home screen that is displayed first when the digital television 10 is activated. The home screen is generated by the extended function execution device 1 and is displayed by the television signal processing device 2 in the extended function execution screen full display mode.

  The screen 80 includes buttons (icons) for each application that can be executed by the extended function execution apparatus 1. When the “TV” button is tapped, the input determination unit 41 notifies the direct UI unit 42 that the “TV” button has been tapped. When the direct UI unit 42 is activated for the first time, the direct UI unit 42 first determines to display the broadcast video of the currently selected channel (for example, Ch1) in the TV screen full display mode. When the corresponding command and display mode are notified from the display instruction unit 46 to the instruction analysis unit 61, the output control unit 63 displays the screen 81 on the display unit 5. When the “controller” button is tapped on the screen 80, the controller application 43 is activated together with the direct UI unit 42, and the television signal processing apparatus 2 displays the screen 82 without using the screen 81. May be.

  When the television screen is tapped in the state of the screen 81 (event 1 in FIG. 6A), the display mode is determined by the direct UI unit 42, and the extended function execution screen is generated by the controller application 43. The output control unit 63 displays a screen 82 in accordance with the designated display mode and extended function execution screen. The same applies to the transition from the screen 83 to the screen 84.

  When the “panel close” button is tapped on the screen 82 (or the screen 84) (event 5 in FIG. 6A), the direct UI unit 42 determines the display mode. In accordance with this, the output control unit 63 displays the screen 81 (or screen 83). Even when the television screen is tapped on the screen 82 (screen 84) (event 4 in FIG. 6A), the output control unit 63 displays the screen 81 (or screen 83). When the “return to home” button is tapped (event 6 in FIG. 6A), the display mode is determined by the controller application 43, and information on the home screen is read from the storage unit 50 by the extended function control unit 40. . In accordance with this, the output control unit 63 displays the screen 80.

  When a touch operation that can distinguish and indicate two types of directions is performed on the TV screen, for example, a left flick (an operation that pays a finger from right to left) or a right flick (an operation that pays a finger from right to left) Corresponding to each direction, the channels are switched in ascending or descending order.

  Specifically, when a left flick is performed on the television screen on the screen 81 (or the screen 82) (event 2 in FIG. 6A), the direct UI unit 42 causes the digital television 10 to execute. Determine the operation (operation to switch to the channel next to the currently selected channel). A command for instructing this operation is generated by the command generation unit 45 and transmitted to the command execution unit 62 (channel selection unit) via the display instruction unit 46 and the instruction analysis unit 61. The tuning unit switches 1ch to 2ch according to the command. As a result, the output control unit 63 displays the screen 83 (or the screen 84). Here, the display mode is not changed.

  On the other hand, when a right flick is performed on the television screen on the screen 83 (or the screen 84) (event 3 in FIG. 6A), the direct UI unit 42 causes the digital television 10 to execute an operation ( The operation to switch to the channel before the currently selected channel) is determined. The channel selection unit switches 2ch to 1ch in accordance with a command for instructing the above operation. The output control unit 63 displays the screen 81 (or screen 82). Here, the display mode is not changed.

  When the number button on the extended function execution screen is tapped on the screen 82 (event 7 in FIG. 6A), the controller application 43 causes the digital TV 10 to execute (switch to the tapped number channel). ). For example, when the “2” button is tapped, the operation of switching to 2ch is determined. The channel selection unit switches to 2ch in accordance with a command that commands the above operation. The output control unit 63 changes the display on the display unit 5 from the screen 82 to the screen 84. Here, the display mode is not changed. When the “1” button is tapped on the screen 84, the channel selection unit switches to 1ch according to the determination of the controller application 43. The output control unit 63 changes the display of the display unit 5 from the screen 84 to the screen 82.

  For example, when an external event occurs in the display state of the screen 83 (or screen 84) (event 8 or 9 in FIG. 6A), the schedule application 44 notifies the schedule to be notified at that time. Generate the screen as an extended function execution screen. Then, the display mode is determined so that this extended function execution screen is displayed. The output control unit 63 displays the received extended function execution screen together with the television screen based on the determined display mode. That is, the screen 85 (or screen 86) is displayed. Since the screen 84 was originally in the mixed screen display mode, when the screen 84 changes to the screen 86, the display mode does not change as a result. As described above, the schedule application 44 locks the function of the direct UI unit 42 until the “executed” button is tapped while the screen 85 (or the screen 86) is displayed. Therefore, no matter what touch operation the user performs on the television screen of the screen 85 (or screen 86), the output control unit 63 maintains the display of the screen 85 (or screen 86).

  When the “executed” button included in the extended function execution screen on the screen 85 (or screen 86) is tapped (event 10 in FIG. 6A), the schedule application 44 returns to the previous display state. Decide that. In the example of FIG. 7, the screen immediately before the screen 85 (or screen 86) is the screen 83 (or screen 84), and the information on the screen 83 (or screen 84) is stored in the storage unit 50 as the previous screen information. Has been.

  When the “executed” button on the screen 85 is tapped, the schedule application 44 designates the full TV screen display mode in order to return to the screen 83. The output control unit 63 displays the screen 83 according to the designated display mode. On the other hand, when the “executed” button on the screen 86 is tapped, the schedule application 44 instructs the controller application 43 to resume execution in order to return to the screen 84. The controller application 43 generates an extended function execution screen for controller keys and supplies it to the output control unit 63 via the display instruction unit 46. The output control unit 63 displays a screen 84. When the television signal processing apparatus 2 returns to the screen 83 (or the screen 84), the schedule application 44 unlocks the direct UI unit 42.

[Processing Flow of Extended Function Execution Device 1]
FIG. 8 is a flowchart showing the flow of processing of the digital television 10, in particular, the extended function execution device 1.

  When a touch operation is performed on the touch panel 4 (YES in S101), the input determination unit 41 performs the touch operation on the extended function execution screen based on the touch position detected by the touch panel 4. Or whether it was performed on the television screen (S102 and S103).

  When it is determined that the touch operation has been performed on the extended function execution screen (YES in S102), the input determination unit 41 generates the extended function unit 47 (for example, the controller application 43 or the schedule application 44) that generated the extended function execution screen. Etc.) is transmitted to the touch operation information (S104). The touch operation information may include all or all of the coordinate information of the touch position, the information specifying the touched object, and the type of touch operation.

  The extended function unit 47 (application) executes a predetermined extended function based on the received touch operation information (S105). Specifically, at least one of determining an operation to be executed by the digital television 10 (television signal processing device 2), determining a display mode, and generating an extended function execution screen is executed. . Each extended function unit 47 does not execute the extended function even if the touch operation information is received until the lock is released when the execution is restricted by another extended function unit 47. Alternatively, it is preferable that the determined operation, display mode, and extended function execution screen are not output.

  On the other hand, when it is determined that the touch operation has been performed on the television screen (NO in S102, YES in S103), the input determination unit 41 transmits the touch operation information to the direct UI unit 42 (S106).

  The direct UI unit 42 executes direct UI processing based on the received touch operation information (S107). Here, the direct UI unit 42 determines at least one of the operation to be executed by the television signal processing device 2 and the display mode to be changed based on the display mode when the touch operation is performed and the type of the touch operation. To do.

  The application that executed S105 or S107 based on the supplied touch operation information transmits the execution result to each downstream unit as necessary (S108). For example, when the direct UI unit 42, the controller application 43, and the schedule application 44 determine an operation to be executed by the television signal processing device 2, the determined operation is transmitted to the command generation unit 45. When the display mode to be changed is determined, the determined display mode is transmitted to the display instruction unit 46. When the controller application 43 and the schedule application 44 newly generate an extended function execution screen, the controller application 43 and the schedule application 44 transmit the generated screen to the display instruction unit 46.

  Subsequently, the command generation unit 45 generates a command statement for instructing the television signal processing device 2 to execute the operation transmitted from any application as a command understandable by the television signal processing device 2 ( S109). The display instruction unit 46 transmits the generated command to the television signal processing apparatus 2 via the serial bus (S110). If the operation is not determined by the application, steps S109 and S110 are omitted.

  Further, the display instruction unit 46 transmits the display mode transmitted from one of the applications to the television signal processing device 2 via the serial bus (S111). If the display mode is not designated by the application, the step of S111 is omitted.

  In addition, the display instruction unit 46 transmits the extended function execution screen generated by any application of the extended function unit 47 to the television signal processing apparatus 2 via HDMI (S112). If the extended function execution screen is not generated by the application, step S112 is omitted.

  S109 and S110, S111, and S112 are not limited to the order shown in the figure, and may be performed by switching the order.

[Processing Flow of Television Signal Processing Device 2]
FIG. 9 is a flowchart showing the flow of processing of the digital television 10, particularly the television signal processing device 2.

  When the instruction analysis unit 61 receives a command from the extended function execution device 1 (YES in S201), the command is a subject that executes the command from the instruction analysis unit 61 (command execution unit 62 such as a channel selection unit). Is transmitted to. The command execution unit 62 executes the command and outputs the result downstream (S202). For example, when the channel selection unit selects a new channel according to the command, the video signal of the channel is transmitted to the control unit that executes various circuits for processing the video signal, and finally to the output control unit 63. Supplied. In this case, the output control unit 63 displays the video of the broadcast program of the new channel in the TV screen area of the display unit 5.

  When instruction analysis unit 61 receives the display mode from extended function execution device 1 (YES in S203), the display mode is transmitted from instruction analysis unit 61 to output control unit 63. The output control unit 63 controls the scaling unit 26, the scaling unit 27, and the blending unit 28 to change the layout of the television screen and the extended function execution screen according to the designated display mode (S204).
