Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and more particularly to a television receiver which receives a program signal and a video signal containing control information for executing an application program, executes the program, and displays an image on a display screen. It relates to a television receiver to be displayed.

[0002]

2. Description of the Related Art In recent years, with the digitization of broadcasting,
Two-way broadcasting, in which not only audio but also application (also called an interactive program) programs are multiplexed and broadcast, has become possible.

In the interactive broadcast system, a composite video signal in which a program signal including control information for executing an application program is multiplexed is transmitted to an interactive TV receiver via an artificial satellite. As shown in FIG. 2, the two-way TV receiver has a program storage memory 31,
An SD (on-screen display) signal generator 32, a signal synthesizer 33, a TV monitor 34, and a video 35 for recording are provided.

A signal received by an antenna and a tuner (not shown) is separated into a program signal and a video signal in a bidirectional TV receiver. After the program signal is temporarily stored in the program storage memory 31, the OSD signal generation unit 3
2 to be executed. For example, if a certain program displays a certain on-screen image (for example, characters, symbols, and patterns) in a partial area of the display screen of the TV monitor 34, the OSD signal generator 32 displays the on-screen image. An OSD signal for generating the signal is generated and supplied to the signal combining unit 33.

[0005] The video signal and the OSD signal are combined by a signal combining section 33 and supplied to a TV monitor 34 and a video 35 for recording. As a result, the composite image in which the on-screen image is overwritten on the original video of the TV program is displayed on the TV monitor 3.
4 and is recorded on the recording video 35 as necessary. When the viewer presses a button on the remote controller according to the on-screen image, the OSD signal generator 32 is programmed to perform some operation.

[0006]

As described above, in the conventional two-way TV receiver, the on-screen image is displayed on the display screen of the TV monitor 34 whenever an instruction to display the on-screen image is issued by a program. Was.

However, since the on-screen image covers a part of the original video of the TV program, some viewers may not want to display the on-screen image.

Further, even if an on-screen image is recorded on the video 35, a program corresponding to the on-screen image is not stored in the program storage memory 31 at the time of reproduction. Nor. On the other hand, for example, when a concert ticket is purchased according to the on-screen image, there may be a case where the user wants to record information about the concert such as the date and place of the concert.

Therefore, a main object of the present invention is to provide a TV receiver capable of selecting whether to display an on-screen image on a display screen.

Another object of the present invention is to provide a TV capable of selecting whether or not to record an on-screen image.
It is to provide a receiver.
