Abstract
Reproduction instruction and inherent address information from a control unit 3 are sent to drive units 1, 2. Thus, compressed video signals every groups of pictures to which inherent address information are respectively added are outputted from the drive units 1, 2. They are edited after undergone switching at a switch circuit 4. The edited compressed video signals are transmitted to a decoding unit 5. This decoding unit 5 detects, by using inherent address information, the editing point of the video signals which have been edited after undergone switching to carry out decoding processing thereof to output a video signal, thereby making it possible to obtain a video signal of satisfactory picture quality without outputting noise at the editing point.
