And the like, and a program for encoding can be created.

At this time, in the CM insertion device, the encoding start point and the encoding end point specified and input by the operator and the time code supplied from the video tape recorder at this time are used for the encoding start to end. The time is calculated in seconds, and the obtained time (hereinafter, referred to as encoding time) is stored as one data of the program. Also, in the CM insertion device, the video signal and the audio signal of each CM recorded on the video tape are encoded by the encoder for the encoding time from the designated encoding start point in accordance with the program thus created.
