Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staggered broadcasting system suitable for staggered broadcasting of a scheduled program due to uncertain factors such as extension of sports broadcasting such as baseball or special program broadcasting.

[0002]

2. Description of the Related Art Generally, in broadcasting programs, it is required to delay a scheduled program and perform staggered broadcasting due to uncertain factors such as extension of a sports program and special program broadcasting. In such a time difference broadcasting system, a plurality of video tape recorders (VTRs) are combined and arranged, and a plurality of these VTs are arranged.
By setting each recording / reproducing time of R in advance according to the reproducing time and controlling the recording / reproducing operation in time series,
Time difference broadcasting is realized by recording time difference programs in a plurality of VTRs in time series and reproducing and outputting the recorded time difference programs in time series.

However, in the above-mentioned staggered broadcasting system, the VTR is set to the recording operation state, the program is recorded for a predetermined time, and then the rewind (RW) or cue-up (CUE-UP) operation is performed. In order to set the magnetic tape at the reproducing position by performing the so-called "heading", a certain time is required for the recording / reproducing operation time (for example, due to its configuration, 15).
It is difficult to set it to less than a second). As described above, when it is difficult to broadcast the time difference instantaneously and the time difference is restricted, for example, when a live sports such as baseball is extended and the extension is instantaneously ended, a wasteful broadcast is inserted in the middle. However, there is a problem in that its handling is troublesome.

Further, according to this, since the reproduction time of the staggered program must be set in advance and the recording / reproducing operation time of the VTR must be set, the end of the live sports must be further extended than expected. In such a case, there is a problem that the viewer service is inferior because it is difficult to deal with it.

[0005]

As described above, the conventional time difference broadcasting system has the problems that it is troublesome to handle, lacks flexibility, and inferior in viewer service. The present invention has been made in view of the above circumstances, can simplify the configuration, and can simplify the handling, and
It is an object to provide a time difference broadcasting system capable of improving the degree of freedom in handling.

[0006]

According to the present invention, there are provided a memory means capable of reproducing and outputting while recording a broadcast signal, a plurality of recording / reproducing means for recording the broadcast signal and selectively reproducing and outputting the broadcast signal, Switching means for outputting either the broadcast signal recorded in the memory means or the broadcast signals recorded in the plurality of recording / reproducing means, and the memory means for setting the recording operation state to record the broadcast signal, and the memory means When a broadcast command is input within the recording time length of, the new broadcasting signal is recorded while the broadcasting signal recorded in the memory means is reproduced and output through the switching means, and the recording time length of the memory means is If the broadcast command is not entered in
Within the recording time length, one of the plurality of recording / reproducing means is set to the recording operation state to continuously record the broadcast signal, and the broadcast signal recorded by the memory means is recorded in response to the broadcast command. The reproduction output is output via the switching means, the time difference between the recording start time and the reproduction start time of the memory means is calculated, and based on the time difference and the reproduction time of the memory means, A time difference broadcasting system is configured by including control means for setting a recording / reproducing operation sequence and controlling the operation.

[0007]

According to the above construction, when the broadcast command is input within the recording time length of the memory means, the recorded broadcast signal is reproduced and output while recording a new broadcast signal in the memory means, and the time difference broadcasting is performed. Is done. When the broadcast command is not input within the recording time length of the memory means, first, one of the plurality of recording / reproducing means is set to the recording operation state and the broadcast signal is continuously recorded in the recording operation of the memory means. In response to the broadcast command, the broadcast signal recorded by the memory means is reproduced and output, and the time difference between the recording start time and the reproduction start time of the memory means is calculated, and based on this time difference and the reproduction time of the memory means. By setting the recording / reproducing operation sequence of the plurality of recording / reproducing means and controlling the operation, continuous time difference broadcasting is performed.
As a result, without setting the time difference broadcasting time in advance,
Instantaneous time difference broadcasting is possible, its handling is simplified, and moreover, time difference broadcasting time can be variably set, and the degree of freedom in its handling is obtained.
