Abstract

PURPOSE:To simplify the handling and to improve the decree of freedom of handling. CONSTITUTION:When a broadcast command is in existence within a semiconductor memory 12 for its recording time length capacity, a recorded broadcast signal is reproduced while the broadcast signal is recorded in the semiconductor memory 12 to execute a time difference broadcast. When no broadcast command is in existence within the semiconductor memory 12 for its recording time length capacity, a 1st VTR 13 is set in the recording operating state and the recording of the broadcast signal is executed continuously with the recording operation of the semiconductor memory 12, and while the broadcast command is inputted, the voltage signal recorded in the semiconductor memory 12 is reproduced and the time difference between the recording start time and the reproduction start time in the semiconductor memory 12 is calculated. Then the operating sequence of 1st-3rd VTRs 13-15 is set based on the reproduction time of the semiconductor memory 12 and the time difference to control an operation and to execute a time difference broadcast.

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.
