Next, the operation of the television receiver configured as described above will be described. Multiple users each
It has one remote control device as described above, and inputs control information such as channel and volume from the data input unit 41. This control information is transmitted from the signal transmission unit 45 to the television receiver together with the ID information and the position information.

A signal from each remote control device is received by the receiving section 1 of the television receiver main body, and the remote control ID extracting section 3, the position information extracting section 4, and the control information extracting section 5 of the demodulating section 2 are provided.
Retrieves ID information, position information, and control information, respectively. Information on the ID and position of the remote control device is output to the ID management unit 6 and control information is output to the tuner management unit 9.

The tuner management section 9 distributes the control information extracted by the control information extraction section 5 to the tuners 11 to 14 corresponding to the remote control ID based on the ID information from the remote control ID extraction section 3 to obtain a desired video. Tune and tune the signal. Here, the remote controller and the tuner have a one-to-one correspondence.
When using a single unit, four tuners are required.

The ID management unit 6 manages the correspondence between the remote control device, the tuner, and the window by using ID information of the remote control device, and the information is stored in the ID table 7. As shown in FIG. 4, the ID table 7 includes a remote control ID, a tuner ID, a window ID, and position information of the remote control device, and the remote control ID and the tuner ID have a one-to-one correspondence. The window ID is assigned when a window is generated, and is deleted when the window is deleted.

In accordance with an instruction from the ID management unit 6, the window generation unit 22 of the window management unit 21 generates / deletes a window serving as a base for mapping received images by the tuners 11 to 14, and performs image generation.
Output to 5

Here, in the window decoration section 24, FIG.
As shown in (1), the window frame generated by the window generation unit 22 is colored corresponding to each remote control ID. The color of the window frame corresponding to this remote control ID is
It is stored in the table of the window decoration data section 23, and it is possible to display a plurality of windows with a frame of a different color according to the remote control device that operates the window.

In the image synthesizing section 25, the window management section 2
In each of the multiple windows created by 1,
An image is generated by mapping video signals from tuners 11 to 14 corresponding to the window ID. For example, when the ID table 7 shown in FIG. 4 is provided, the image from the tuner with ID 2 is mapped on the window with ID 4. The mapped window image is output to window arrangement unit 26.

As shown in FIG. 6, the window arranging section 27 of the window arranging section 26 performs the following operations based on the (x, y) coordinates in the remote control position information of the ID table 7.
Transform each window. A method of deforming this window will be described for the case where the remote control device moves in the x-axis direction.

As shown in FIG. 7, when the remote control device is located at a position φ degrees to the right from the center of the projection plane of the display device 31, the window corresponding to the ID of the remote control device also becomes y.
An image is created as if the image was rotated counterclockwise by θ degrees about the axis of rotation in the axial direction and projected. Therefore, as shown in FIG. 8, it is possible to display on the display device 31 a trapezoidal image that appears to rotate about the center of the window in accordance with the position of the remote control device.

When the remote control device moves to the left from the center of the projection plane, the window is subjected to a rotation process in the opposite direction to the case of the right. 7 and 8, a method has been described in which, when the remote control device moves in the x-axis direction (left-right direction), the effect of rotating the remote control device around the y-axis is described. When the image is moved (up and down), a transformed image is created and displayed as if it were rotated about the x-axis.

Thus, not only can the user easily understand which remote control device corresponds to which window, but also a user who is obliquely viewing the projection plane of the display device 31 can feel uncomfortable. This makes it possible to provide an easy-to-read display window without any problem.

The window arrangement control section 29 arranges each window transformed by the window transformation section 27 based on the position information of each remote control device and the information of the arrangement description table 28. That is, as shown in FIG. 6, each display window on the screen is rearranged so as to be closest to the position of the corresponding remote controller.

The arrangement description table 28 also includes information such as adjustments between windows that do not overlap other windows when the size of a certain window changes, and how to open windows according to the position of the user. Is described. The signal from the window arrangement control unit 29 is
The image is output to the display device 31 via the image generation unit 30.

Further, the transmission control section 19 performs a process for dividing the audio signal received by each of the tuners 11 to 14 in time series and transmitting the divided signals from the transmission section 20 to the corresponding remote control devices. Thus, each remote control device can receive and output an audio signal related to the window video to be operated.

The remote control device detection section 8 periodically outputs a confirmation signal via the transmission section 20 to the remote control device corresponding to the window generated by the request from the ID management section 6. Upon receiving the confirmation signal from the television receiver, the remote control device transmits a remote control ID, position information, and control information managed by the remote control information management unit 44 from the signal transmission unit 39.

The television receiver determines the presence or absence of a remote control device based on the result of reception from the remote control device. When the remote control device detection unit 8 does not detect the confirmation of the remote control device, an instruction is sent to the window generation unit 22 via the ID management unit 6 to delete the corresponding window.

Thus, when a certain remote control device goes out of a range that cannot be confirmed from the television receiver main body, it can be considered that the user has gone out of the viewing range of the television, and the corresponding window can be deleted. The screen can be used effectively.

The audio signal input from the signal receiving unit 46 is demodulated by an audio demodulation unit 47, and the audio related to the video currently being viewed by the remote control device is output from a speaker or an earphone terminal of the audio output unit 48. It is possible to output.

In the above embodiment, the number of tuners is four. However, the number of tuners is not limited to four and may be any number. In addition, since a television receiver has been described as an example, all images displayed in the window are transmitted from the tuner, but the present invention is not limited to this, and images from a video player, a DVD player, a video camera, and the like are mapped to each window. You may.
