Abstract:

PROBLEM TO BE SOLVED: To inhibit missing in an video image at replaying, for both a coded video signal to be transmitted and that to be recorded, even when recording for the same video signal is indicated while transmitting a video signal coded by using both an intraframe coding method and an interframe coding method.

When recording the coded image signal is indicated in the act of outputting from a communication part 103, recording is started from the head of the picture group containing a frame corresponding to the recording indication or the next picture group. When recording is indicated in the middle of the picture group, a past coded image signal stored in a buffer part 106 is utilized.
