Abstract

PURPOSE:To view a desired broadcasting at all times by storing once a television signal, outputting a reproducing signal read at a prescribed delaying time interval and selecting a reproducing output signal equivalent to a desired delaying time. CONSTITUTION:An input signal 1 from a television signal input terminal T1 is inputted to a memory part 2, and reproducing the outputs 10-14 of a signal delayed at plural prescribed time intervals are always outputted. Presently, for example, when the delaying time equivalent to the delaying output 12 of the memory part 2 is set by a delaying time setting part 3, a setting signal is added to a delaying time selecting part 4. A delaying time selecting signal 7 is outputted from the selecting part 4, added to a gate circuit 17 and the circuit 17 is opened. Consequently, an output 12 passes through the circuit 17 as it is, is added to an OR circuit 20 and outputted through the circuit 20 to a television signal output terminal T2. Thus, the broadcasting to fail to see a desired program can be viewed at all times.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a delay playback device for television broadcasting.

[Prior Art] Conventionally, when it is not possible to directly view a television broadcast at the time it is broadcast, it is recorded on a video tape recorder (VTR) and then viewed at a desired time. It is now possible to easily play and view a VTR.

However, if you try to watch a program you want to watch from the middle of the program after the broadcast starts a little later, it is difficult to go back to the beginning and watch the program from the beginning.

In daily life, it is very likely that you will not be able to watch the program you want to watch in time for the start time.

If you try to compensate for this with a VTR, if you want to watch a long program, for example one or two hours, you can set the VTR to the broadcast start time in advance and record it. If you start watching TV 30 minutes late, you will have to play the first 30 minutes on the VTR after the program finishes broadcasting.

This is because if the broadcast program is a drama, people will end up watching the ending first, which will kill their interest. Furthermore, if the program is educational, it may not be possible to understand the content of the program.

[Problems to be solved by the invention] Therefore, the purpose of the present invention is to enable you to watch the program you want to watch from the beginning even after the broadcast has started, and to enable you to watch the program you want to watch from the beginning, even if there is a slight delay. According to the broadcast time,
The purpose of the present invention is to provide a television video signal delay playback device that allows you to finish viewing.

[Means for Solving the Problems] To this end, the present invention temporarily stores broadcast television signals, reads them out in sequence at desired delay time intervals, and outputs reproduced signals. The reproduction output signal corresponding to the delay time of is selected and made available for viewing.

That is, the present invention provides means for storing a television signal, means for delaying the television signal reproduced from the storage means by a predetermined delay time and outputting a plurality of delayed television signals individually, and a means for individually outputting a plurality of delayed television signals, and and which one of the plurality of individually outputted delayed television signals is taken out by the setting means, and one of the plurality of delayed television signals corresponding to the set delay time is selected from among the plurality of delayed television signals. The present invention is characterized by comprising means for extracting only the television signal delayed by the time.

[Function] Accordingly, by implementing the present invention, it is possible to watch a television program that is currently being broadcast with a reproduction signal having a desired delay time, so that the program can be watched from the point where it is currently being broadcast. You can watch it from the beginning.

It is also possible to go back and review the broadcast while directly viewing it. Alternatively, even if you drop out of the program and can't watch it, you can continue to watch it with a delayed playback output signal corresponding to the time you missed.
This will help greatly increase the effectiveness of TR.

[Example] Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the figure, 1 is a TV signal input from the TV signal input terminal T, 2 is a TV signal storage unit, 3 is a delay time setting unit, 4 is a delay time selection unit, 5.6° 7.8. '9 is the delay time selection signal, ! 0, 11, 12, 13.14 are TV output signals delayed by a predetermined time interval, Is, 16.17
, 18 and 19 are gate circuits, and 2o is an OR circuit.

The television signal 1 from the television signal input terminal T□ is input to the television signal storage section 2. And from storage part 2,
The delayed reproduction outputs 10 to 14 of the television signal are always outputted at a plurality of predetermined time intervals.

On the other hand, the setting output from the delay time setting section 3 is connected to the delay time selection section 4.

The output lO~14 from the storage section 2 is sent to the gate circuits 15~1.
9, respectively.

Selection signal outputs 5 to 9 from the delay time selection section 4 are connected to the other input terminals of the gate circuits 15 to 19, respectively.

The outputs of the gate circuits 15 to 19 are respectively connected to the input terminals of the OR circuit 2°.

The output of the OR circuit 20 is then connected to the output terminal T2.

Therefore, for example, when the delay time setting section 3 sets a delay time corresponding to the delay output 12 of the storage section 2, the setting signal is applied to the delay time selection section 4, and the delay time selection section 4
A delay time selection signal 7 is outputted from the gate circuit 1 and applied to the gate circuit 17 to open the gate circuit 17.

The delayed output 12 passes through the gate circuit 17 as it is and is ORed.
The signal is added to the circuit 20, passes through the OR circuit 20, and is output to the television signal output terminal T2.

In this way, the broadcast can be viewed with the playback output of TV No. 8 delayed by the desired delay time.

[Effects of the Invention] As explained above, according to the present invention, even when a desired program starts in time and the user tries to watch it late, the replay broadcast is delayed by the necessary time. You can immediately watch broadcasts that you missed due to a delay.

Furthermore, by appropriately selecting and providing the length of the delay time and the number of setting stages, you can watch the desired TV broadcast program at any time during the broadcast time, without worrying about the start time of the TV broadcast. , it is also possible to continue viewing and then go back and review. Alternatively, it is possible to go back and revise from the previous step.
