Abstract

PURPOSE:To prevent the fault from affecting the other circuits, by discontinuing forcedly the process to then proceed to the process of another circuit in case the multiple coder or decoder is retained for a long time at the specific circuit. CONSTITUTION:The picture signals are supplied to coder 3 from receiving parts 11-1n via change-over switch 2, and the coded picture signals are stored in picture signal storing memory 6. In case the transfer is delayed between coder 3 and memory 6, the fault is detected by the watch incorporated in control part 4. And switch 2 is changed over to another circuit, and at the same time the circuit switching request is transmitted also to memory 6.
