Abstract

PURPOSE:To automatically switch a program to an original program after the lapse of a constant time even when the program is switched to another program by providing a tuner control circuit to switch a state to another receiving state by the command of a remote control transmitter and a timer. CONSTITUTION:The signal of a tuner 1 is reproduced by a signal processing circuit 2 in an ordinary case, and received by a CRT4 via a picture display circuit 3. And commercial broadcasting is inputted in the program in an ordinary viewing state, and by issuing the command by a viewer by using the remote control transmitter 5, it is received by a remote control reception part 6, then, a time is measured by the timer 7. Simultaneously, the receiving channel of the tuner 1 is changed by the tuner control circuit 8. And by passing the signal through a digital signal processing circuit 9, plural pictures can be displayed simultaneously. Meanwhile, since a lapse time by the timer 7 is displayed on a screen simultaneously, when two minutes of the commercial broadcasting elapse, the state is returned to an original receiving state automatically by the timer, and it is possible to dissolve forgetting to return the program to the original program, etc.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention displays the elapsed time on the screen at the same time that signals are received for a certain period of time according to a viewer's command, and automatically displays the elapsed time after the certain period of time has elapsed. This invention relates to a television receiver that receives the original signal.

[Conventional technology]

Conventionally, when a commercial broadcast comes on while watching a television broadcast, the user may change the channel or watch another program in order to check the content of the other broadcast. This has become possible because channel switching using a remote control has become commonplace in recent years, and commands can be given relatively easily.

[Problem to be solved by the invention]

Conventionally, channels have been easily switched using a remote control. For this reason, there are problems in which the user sometimes forgets to return to the original program, or has to worry about when the commercials in the program he was watching will end.

This invention was made to solve the above-mentioned problems, and its purpose is to provide a television receiver that can automatically switch to the original program after a certain period of time even if the program is switched to another program. shall be.

[Means to solve the problem]

The television receiver according to the present invention is configured to display the elapsed time at the same time as it enters a different reception state for a certain period of time according to a remote control command from a viewer, and returns to the original reception state after the elapse of a certain period of time.

[For production]

In this invention, after receiving a command from a remote control, etc.,
At the same time as operating a timer and automatically changing the reception channel etc., it is possible to automatically switch back to the original reception state after a predetermined period of time has elapsed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram of an automatic switching device in a television receiver according to the present invention. This is a screen display circuit that displays images on the cathode ray tube 4.

5 is a remote control transmitter, and a signal from it is received by a remote control receiver 6. 7 is a timer, 8 is a tuner control circuit, and 9 is a digital signal processing circuit.

FIG. 2 shows an example of a television screen display, where 11 represents nine screens displayed on a cathode ray tube, 12 represents the receiving channel number, and 13 represents the elapsed time after the reception status was changed.

Next, the operation will be explained.

Normally, the signal from the tuner 1 is reproduced by a signal processing circuit 2, passed through a screen display circuit 3, and then received by a cathode ray tube 4. Thus, when a commercial is broadcast during a program in a normal viewing condition, when the viewer issues a command using the remote control transmitter 5, the command is received by the remote control receiver 6 and the time is counted by the timer 7. At the same time, the tuner control circuit 8 changes the reception channel of the tuner I. In addition, by passing the digital signal processing circuit 9,
For example, nine screens such as those shown in FIG. 2 can be displayed at once. On the other hand, since a timer is used to simultaneously display the elapsed time on the screen, for example, when two minutes have elapsed since the end of a commercial, the timer automatically returns to the original reception state.

Although the embodiment shows a change in the reception state, the reception state may change from the channel currently being viewed to another channel or another input such as video.

In addition, the elapsed time display by the timer 7 may display the remaining time until the original state returns, or both may be displayed at the same time.Furthermore, another reception status can be changed automatically from one channel to another, instead of only one channel. repeating things,
Alternatively, it is also possible to display multiple screens at once, or to display parent and child screens such as picture-in-picture.

Further, although the present invention has been described with reference to an example in which the display is performed based on a remote control command, it is also possible to automatically display multiple screens when the power is turned on, and return to the original state after a certain period of time.

[Invention effect]

As explained above, according to the present invention, the elapsed time is displayed at the same time as the reception state is switched to another reception state for a certain period of time according to a command from the remote control, and the reception state is returned to the original reception state after the elapse of a certain period of time. You can watch other programs and automatically return to the original program when the commercial ends, eliminating the problem of forgetting to return to the original program as in the past.
