Here, when a channel designation or data broadcast program acquisition instruction is input, coordinate data indicating a display position touched by the user is recorded and held in the memory 26 by the touch panel controller 24, and coordinate data is stored by the CPU 25. This is notified to the receiving terminal device 10 via the interface 21.

  When inputting from such a touch panel 23, a software operation panel representing an input position from the touch panel 23 is displayed on the monitor 22 under the control of the CPU 14 of the receiving terminal device 10. The software operation panel is displayed based on an area (television image area) provided for displaying video (moving image) received by television broadcasting. That is, the display position is controlled so that the data content is not hidden by displaying the software operation panel. Basically, the software operation panel is displayed in the television image area so that the input operation for the data content can be performed.

  The display controller 27 switches the selector 28 as necessary to cause the monitor 22 to perform display by processing on the display device 20 side.

Further, display data of the software operation panel displayed on the monitor 22 of the display device 20 is also recorded in the memory 15 (see FIG. 8).

  FIG. 2 is a block diagram illustrating a functional configuration realized by executing various programs stored in the memory 15 by the CPU 14 of the receiving terminal device 10.

  The control unit 30 is a function of a manager program, and starts up each functional unit (program) such as the BML browser unit 31, the software operation panel unit 33, and the moving image display control unit 35, and transmits information such as coordinate data from the touch panel 23. To control.

  The BML browser unit 31 is a function based on the BML browser program, and performs display of data content received by data broadcasting and control of operations on the content. The BML browser unit 31 has a data area for displaying data content received by data broadcasting and a television image area for displaying video (moving image) by television broadcasting in accordance with data described by BML received by data broadcasting. Set.

  The coordinate information management unit 32 manages information of each area set by the BML browser unit 31 at the time of data broadcast reception, display control of the software operation panel by the software operation panel unit 33, and television image by the moving image display control unit 35. (Movie) Provided for display control.

  The software operation panel unit 33 displays a software operation panel on the monitor 22 in order to accept an input operation from the touch panel 23 instead of the remote control device, and operates the software based on the coordinate data input by the operation on the touch panel 23. Operation contents for the panel are acquired and notified to the BML browser unit 31.

  The touch panel communication unit 34 controls transmission of coordinate data input by an operation on the touch panel 23 of the display device 20.

  The moving image display control unit 35 extracts video data from the television broadcast received by the tuner 13 and displays it on the television image area set by the BML browser unit 31.

  The tuner control unit 36 controls the tuner 13 to perform channel selection and the like.

  FIG. 3 shows a VRAM 17 (17a, 17b, 17c) image for displaying on the monitor 22 the data content received by the data broadcast on the monitor 22, the video received by the television broadcast, and the software operation panel.

  FIG. 3A shows a display state in which data broadcasting and television broadcasting are received. As shown in FIGS. 3A and 3B, data content received by data broadcasting is written and displayed in, for example, the VRAM 17b under the control of the BML browser unit 31 (graphics plane). On the other hand, video data received by television broadcasting through the tuner 13 is written in, for example, the VRAM 17a so as to fit in the television image area under the control of the moving image display control unit 35, as shown in FIGS. Displayed (visual plane). As shown in FIG. 3 (1) (a), the display on the monitor 22 is displayed by combining the data content and the video.

  FIG. 3B shows an input operation state using the software operation panel when the data broadcast is received. As shown in FIGS. 3B and 3B, the data content received by data broadcasting is written and displayed in, for example, the VRAM 17b under the control of the BML browser unit 31 (graphics plane). On the other hand, as shown in FIGS. 3B and 3C, the software operation panel data is written and displayed in, for example, the VRAM 17c under the control of the software operation panel unit 33 (visual plane). As shown in FIG. 3 (2) (a), the display on the monitor 22 is displayed by combining the data content and the software operation panel. In the example shown in FIG. 3 (2), an example is shown in which the operation panel is displayed over the entire area where the video by the television broadcast has been displayed. In this case, the data on the software operation panel may be written in the VRAM 17a instead of the video data.

  In addition, as shown in FIG. 3B, the software operation panel is not displayed in the entire television image area, but can be displayed in a translucent manner or scaled. In this case, the software operation panel data is expanded in the VRAM 17c, and is combined with the VRAMs 17a and 17b and displayed on the monitor 22.

Next, the operation in this embodiment will be described.
First, control processing for matching the coordinate system of the monitor 22 of the display device 20 and the touch panel 23 will be described with reference to the flowchart shown in FIG. This control process is performed by the CPU 14 executing a coordinate conversion program recorded in the memory 15.

  In the case of the system configuration shown in FIG. 1, the display device 20 can be replaced and used. Accordingly, there are cases where the aspect ratio of the monitor 22 provided in the display device 20 is 4: 3, or a wide screen of 16: 9.

  For example, when the monitor 22 of the display device 20 is a wide screen (aspect ratio 16: 9) and the aspect ratio of the input video is 4: 3, the display device can display the full screen. A plurality of display modes 20 are provided.

  The setting of the display mode in the display device 20 is performed by the user performing a predetermined operation. The receiving terminal device 10 can know the current display mode of the display device 20 by acquiring the display mode data sent from the display device 20.

For example, when the receiving terminal device 10 outputs an image with an aspect ratio of 4: 3 and is set to a display mode in which the display device 20 converts to a wide screen with an aspect ratio of 16: 9, the coordinate system of the receiving terminal device 10 is ( X, Y) and the coordinate system of the display device 20 is (X ′, Y ′),
X = (3/4) X ′
Y = Y '
The coordinate value can be converted by a process based on the coordinate conversion formula.

  When performing the conversion process, the CPU 14 of the receiving terminal device 10 executes the control process shown in FIG. First, in response to a user instruction input, the CPU 14 acquires display mode data from the display device 20 (step S1), and records this display mode data in the memory 15 (step S2).

  Subsequently, when the coordinate data arrives when the user touches the monitor 22 of the display device 20 (step S3), the CPU 14 compares the display mode data recorded in the memory 15 with the display mode data of the terminal itself. (Step S4), it is determined whether or not the display modes match (Step S5).

  Here, when the display modes do not match (No), the CPU 14 converts the coordinate data from the display device 20 into the coordinate data for the display mode of the terminal itself (step S6), and executes the instruction process based on the coordinate data. (Step S7).

  On the other hand, if the display modes match in step S5 (Yes), the CPU 14 proceeds directly to the process in step S7.

  In this way, the display mode data indicating the display mode of the display device 20 is acquired by the CPU 14, and when the user touches an arbitrary display position of the monitor 22 of the display device 20, coordinate data indicating the display position is acquired. ing. Then, the incoming display mode is compared with the display mode of the own terminal, and the coordinate data from the display device 20 is converted into the coordinate data of the own terminal based on the comparison result.

  Therefore, even if the display device 20 is replaced with a different display mode and used, accurate processing can be performed according to the display content of the touched position in the monitor 22 of the display device 20.

  Next, the data broadcast display process will be described with reference to the flowchart shown in FIG.

  First, the BML browser unit 31 acquires and analyzes data of data broadcasting, extracts television image area information representing an area for displaying video (step A1), and notifies the coordinate information management unit 32 of this information. To do.

  The coordinate information management unit 32 manages the TV image area information extracted by the BML browser unit 31, controls the display of the software operation panel by the software operation panel unit 33, and controls the TV video (moving image) display control by the moving image display control unit 35. To provide for.

  The moving image display control unit 35 acquires the television image area information managed by the coordinate information management unit 32, and writes and displays the video data extracted from the television broadcast in the VRAM 17a according to the television image area indicated by this information. .

  FIG. 6 shows an example of a screen displayed on the monitor 22. As shown in FIG. 6, the BML browser unit 31 interprets data described by BML received by data broadcasting, and displays a data area in which data content acquired by data broadcasting is displayed, and a television image (moving image). ) Is set to display a TV image area.

  In addition, descriptions of contents displayed in the data area, for example, attributes of each object (display frame, character string, figure, etc.) are interpreted, and the displayed display position (coordinates), color, and character font are described. Are displayed under the control of the BML browser unit 31.

  FIG. 7 shows an example of a software operation panel managed by the software operation panel unit 33.

  The software operation panel shown in FIG. 7 corresponds to the blue, red, green, and yellow color buttons, the data button d, and the cursor button that are usually provided in the remote control device for remotely controlling the digital broadcast receiving device. A button is provided. Further, a next screen button for instructing display switching to another button and a position change button for instructing to change the display position of the software operation panel are provided. The software operation panel unit 33 is provided with a plurality of patterns of software operation panels. For example, data content displayed in the data area, that is, a pattern corresponding to an input operation target using the software operation panel is used. And

  The software operation panel is designed to have a size that allows easy input operation through the touch panel 23 when displayed on the monitor 22. When displaying on the monitor 22, it is expanded and displayed so that it may not become smaller than the size designed beforehand. Normally, a sufficient television image area is secured, so that the image is enlarged and displayed in accordance with the television image area.

  Next, the software operation panel display process will be described with reference to the flowchart shown in FIG.

  First, for example, when a user touch operation is performed on the touch panel 23, the software operation panel unit 33 acquires coordinate data by the touch panel communication unit 34, and determines that an activation instruction for the software operation panel is input. (Step B1).

  Note that the activation instruction of the software operation panel may be determined from the received data by the BML browser unit 31 when an operation on the data content received by data broadcasting is required.

  The software operation panel unit 33 acquires content data from the BML browser unit 31 and sets a software operation panel necessary for the current content data (step B2).

  The software operation panel unit 33 acquires the television image area information from the coordinate information management unit 32, and scales the software operation panel according to the area size indicated by this information (step B3). The coordinate information management unit 32 manages the television image area information analyzed by the BML browser unit 31 and provides it in response to a request from the software operation panel unit 33.

  The software operation panel unit 33 displays the scaled software operation panel in the television image area (step B4).

  FIG. 9 shows an example of a screen on which a software operation panel scaled in the television image area is displayed. As shown in FIG. 9, when the software operation panel is displayed in the television image area, an input operation using the software operation panel can be performed while viewing all data contents displayed in the data area.

  FIG. 10 shows an example in which the software operation panel is displayed in a translucent manner. In this case, the software operation panel is made translucent, and the data is expanded and displayed on the VRAM 17c so that a television image can be visually recognized. Thus, when the software operation panel is displayed in the television image area, the input operation using the software operation panel can be performed while confirming the television image.

  The display mode in FIG. 9 or 10 can be switched by the user performing a predetermined operation. The software operation panel unit 33 switches the display form in accordance with an instruction from the user.

  Here, when there is an input operation on the software operation panel (step B7), the touch panel communication unit 34 inputs the coordinate data from the touch panel 23 and passes it to the software operation panel unit 33.

  The software operation panel unit 33 compares the position indicated by the input coordinate data with the position of each button on the software operation panel being displayed, thereby determining the operation content for the software operation panel and causing the BML browser unit 31 to Notification is made (step B8). Note that the coordinate data input by the touch panel communication unit 34 is converted so that the coordinate system is matched by a control process according to a coordinate conversion program.

  Incidentally, in the display example shown in FIG. 9 (FIG. 10), the entire TV operation area can be displayed because the TV image area is sufficiently large, but the TV image area is smaller than the original size of the software operation panel. In this case, it is assumed that the software operation panel is displayed at a position where the area overlapping with the TV image area is maximized.

  Alternatively, when display of the software operation panel is requested when there is no TV image area, the software operation panel is displayed with reference to any one of the four corners of the display screen, for example.

  In such a case, a part of the data area is hidden by the display of the software operation panel. In this case, when there is an input operation to the position change button provided on the software operation panel (step B5), the software operation panel unit 33 uses the display position of the software operation panel as a reference based on, for example, any of the other four corners. The display position of the software operation panel is changed to the position (step B6).

  Thus, an input operation using the software operation panel can be performed while confirming the contents of the data content.

  When the input operation on the software operation panel is completed, the control unit 30 causes the software operation panel unit 33 to delete the software operation panel, and ends the software operation panel display process.

  In the above description, when the TV image area is smaller than the software operation panel, the software operation panel is displayed at the position where the area overlapping with the TV image area is maximized. However, the number of buttons provided on the software operation panel By changing the, the entire size of the software operation panel can be reduced and displayed.

  For example, the BML browser unit 31 interprets the attribute of each object displayed in the data area based on the description in the data received by data broadcasting. Therefore, among the buttons provided on the software operation panel, it is possible to determine which button is used by the operation on the data content.

  For example, in FIG. 11, the item “online” is marked with a blue circle, and when this item is selected, it indicates that an operation on the blue button is necessary. Similarly, the item “Easy registration” is marked with a yellow circle, and when this item is selected, it indicates that an operation on the yellow button is necessary. In this case, the BML browser unit 31 can interpret that the blue button and the yellow button are used in the current data content.

  The software operation panel unit 33 acquires the interpretation result by the BML browser unit 31, expands the software operation panel except for the necessary buttons, and displays it in the television image area as shown in FIG.

  As a result, it is possible to display the software operation panel without hiding the data content and to perform an input operation on the data content without any inconvenience.

  The change of the buttons on the software operation panel may be executed not only when the TV image area is smaller than the software operation panel but also at all times.

  Note that the configuration shown in FIG. 1 used in the above description is an example, and the reception terminal device 10 and the display device 20 may be integrated. In this case, any configuration (CPU, memory, display controller, etc.) common to the receiving terminal device 10 and the display device 20 in FIG.

  Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiment, at least one of the problems described in the column of problems to be solved by the invention can be solved, and described in the column of the effect of the invention. In a case where at least one of the obtained effects can be obtained, a configuration in which this configuration requirement is deleted can be extracted as an invention.
