Abstract
In a decoding system for decoding video signals into original video signals, the requirement for an externally-arranged frame synchronizer is avoided. The decoding system itself incorporates a frame synchronization function. In one form, the decoding system comprises a buffer memory for temporarily storing video signals that have coded by a predetermined coding algorithm. A frame sync signal detector detects frame sync signals out of the video signals temporarily stored in the buffer memory and generates sync detection signals. A reference sync signal detector detects reference sync signals provided from outside and generates reference sync detection signals. A decoder is responsive to the frame sync and reference sync detection signals to read the video signals out of the buffer memory and to decode the video signals.
