Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing a first embodiment of a system in which a broadcast receiving terminal device according to the present invention is used.

  This system includes a broadcast receiving terminal 10 as a broadcast receiving terminal device and a car navigation display device 20 as an external display device. The broadcast receiving terminal 10 and the car navigation display device 20 are provided with interfaces 11 and 21, respectively, and can be connected to each other.

  Meanwhile, the broadcast receiving terminal 10 includes an antenna 12, a tuner 13, a CPU 14, a memory 15, and a display controller 16. A broadcast signal broadcast from a broadcast station (not shown) is received by the tuner 13 via the antenna 12 and then input to the CPU 14 where predetermined video signal processing is performed. Here, the obtained video signal is supplied to the car navigation display device 20 via the display controller 16 and the interface 11. The display controller 16 performs a deflection control process on the car navigation display device 20 based on the video synchronization signal. Therefore, the received video is displayed on the monitor 22 of the car navigation display device 20.

  The car navigation display device 20 further includes a touch panel 23, a touch panel controller 24, a CPU 25, a memory 26, a display controller 27, and a selector 28. Of these, the touch panel 23 is used by the user to input various operation instructions to the broadcast receiving terminal 10 and the car navigation display device 20 such as channel designation and navigation display designation. Also used for input. Here, when a channel designation or data broadcast program acquisition instruction is input, coordinate data indicating a display position touched by the user is stored and held in the memory 26 by the touch panel controller 24, and coordinate data is stored by the CPU 25. The broadcast receiving terminal 10 is notified via the interface 21.

  The display controller 27 switches the selector 28 to car navigation display and causes the monitor 22 to perform car navigation display.

  On the other hand, the CPU 14 of the broadcast receiving terminal 10 includes a display mode acquisition function 14a and a data conversion function 14b as new functions related to the present invention in addition to the normal control function related to the reception display operation of the broadcast signal.

  The display mode acquisition function 14a sends a display mode acquisition request to the car navigation display device 20 via the interface 11 at the time of activation or according to a user instruction, and in response to the acquisition request, the car navigation display device 20 Receives display mode data sent by. The received display mode data is stored and held in the memory 15.

  When coordinate data arrives from the car navigation display device 20, the data conversion function 14b reads the display mode data of the car navigation display device 20 and the display mode data of its own terminal from the memory 15 and compares and collates them. Then, the received coordinate data is converted into the coordinate data for its own terminal, and processing corresponding to the input instruction is executed.

  The memory 15 stores a coordinate conversion program 15a. The memory 15 stores data such as a menu screen to be displayed on the monitor 22 of the car navigation display device 20.

Next, the operation of the system configured as described above will be described.
Although the car navigation display device 20 has a wide screen, when the aspect ratio of the input video is 4: 3, the full screen cannot be displayed in full. Therefore, as shown in FIGS. There are various display modes.

  The display mode can be switched to each mode by the user performing a predetermined operation. The broadcast receiving terminal 10 can know the current display mode of the car navigation display device 20 by acquiring the display mode data sent from the car navigation display device 20.

  The broadcast receiving terminal 10 stores in the memory 15 a coordinate conversion program 15a for converting from the coordinate system of each display mode to the coordinate system of the actual television broadcast.

For example, in the case of mode 1 shown in FIG. 2B, the broadcast receiving terminal 10 outputs a video with an aspect ratio of 4: 3, and is converted into a wide screen with an aspect ratio of 16: 9 by the car navigation display device 20. Therefore, if the coordinate system of the broadcast receiving terminal 10 is (X, Y) and the coordinate system of the car navigation display device 20 is (X ′, Y ′),
X = (3/4) X ′
Y = Y '
It can be converted by the coordinate conversion formula.

  When performing the conversion process, the CPU 14 of the broadcast receiving terminal 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 car navigation display device 20 (step ST3a), and stores and holds this display mode data in the memory 15.

  Subsequently, when the coordinate data arrives when the user touches the monitor 22 of the car navigation display device 20 (step ST3c), the CPU 14 displays the display mode data stored in the memory 15 and the display mode data of the terminal itself. Comparison is made (step ST3d), and it is determined whether or not the display modes match (step ST3e).

  Here, when the display modes do not match (No), the CPU 14 converts the coordinate data from the car navigation display device 20 into coordinate data for the display mode of the terminal itself (step ST3f), and an instruction process based on the coordinate data Is executed (step ST3g).

  On the other hand, when the display modes match in step ST3e (Yes), the CPU 14 proceeds to the process of step ST3g as it is.

  As described above, in the first embodiment, the CPU 14 acquires display mode data indicating the display mode of the car navigation display device 20, and the user touches an arbitrary display position on the monitor 22 of the car navigation display device 20. In this case, coordinate data indicating the display position is obtained. Then, the incoming display mode is compared with the display mode of the own terminal, and the coordinate data from the car navigation display device 20 is converted into the coordinate data of the own terminal based on the comparison result.

  Therefore, even if the car navigation display device 20 in any display mode is used, accurate processing can be performed according to the display content of the touched position in the monitor 22 of the car navigation display device 20.

  The user taps these cross displays one by one. The tapped coordinate values are taken into the broadcast receiving terminal 10 and all cross-display data are stored in the memory 15.

For example, when the display mode of the car navigation display device 20 is mode 2 shown in FIG. 2C, the cross displays of the broadcast receiving terminal 10 are (ax, ay) and (bx, by), respectively, and the car navigation display Since the cross display of the device 20 is (cx, cy) and (dx, dy), respectively, the coordinates (X, Y) of the broadcast receiving terminal 10 corresponding to the coordinates (X ′, Y ′) of the car navigation display device 20 Conversion of
Y = ay = cy = by = dy = Y ′
And Y = Y ′.

Also, the coordinate system on the x side is
X = (bx (cx−X ′) + ax (dx−X ′)) / (cx−dx)
Conversion is possible by the conversion formula.

  As described above, in the second embodiment, the display mode and the coordinate value that has been tapped in advance are stored in the memory 15 of the broadcast receiving terminal 10 in association with each other. When coordinate data touched by 20 monitors 22 is acquired, coordinate data conversion processing is performed by a simple procedure using the coordinate values of the display mode stored in the memory 15 without using the coordinate conversion program 15a. It can be performed.

  In addition, an inexpensive broadcast receiving terminal can be used because it is not necessary to use the memory 15 storing the coordinate conversion program 15a.

(Third embodiment)
The third embodiment of the present invention relates to a processing method when the broadcast receiving terminal 10 acquires the display mode of the car navigation display device 20.

Is displayed.

  Here, when the display mode of the car navigation display device 20 is mode 3, it is displayed on the car navigation display device 20 by scrolling the vertical straight line 22c and the horizontal straight line 22d in the monitor 22 according to a user instruction. It is possible to obtain information on the screen display area of the current video.

  On the other hand, in the CPU 14 of the broadcast receiving terminal 10, the coordinates arrived from the car navigation display device 20 based on the shift amount of the vertical straight line 22c with respect to the vertical reference line 22a and the shift amount of the horizontal straight line 22d with respect to the horizontal reference line 22b. The data is converted to the coordinate data of its own terminal.

  As described above, in the case of the third embodiment, when the user himself / herself adjusts the monitor 22 screen of the car navigation display device 20 to an easy-to-view screen, the car navigation display device 20 receives the adjustment according to the adjusted screen. The coordinate data can be converted into coordinate data for the broadcast receiving terminal 10.

Is determined (step ST7b).

  If the received coordinate data is not coordinate data in the display area 22e in the monitor 22 (No), the CPU 14 ends the process as it is.

  On the other hand, when the received coordinate data is coordinate data in the display area 22e in the monitor 22 (Yes), the CPU 14 compares the coordinate value stored in the memory 15 with the coordinate value of the terminal itself (step ST7c), and the coordinate value That is, it is determined whether or not the display modes match (step ST7d).

  Here, when the display modes do not match (No), the CPU 14 converts the coordinate data from the car navigation display device 20 into the coordinate data for the display mode of the own terminal based on the error of the coordinate values (step ST7e). An instruction process based on the coordinate data is executed (step ST7f).

  On the other hand, when the display modes match in step ST7d (Yes), the CPU 14 proceeds to the process of step ST7f as it is.
