发明名称 VIDEO SIGNAL DECODING SYSTEM HAVING A FRAME SYNCHRONIZER FUNCTION
摘要 A decoding system according to the invention dispenses with an externally arranged frame synchronizer by incorporating the function of the frame synchronizer into the decoding system itself. The decoding system decodes coded video signals coded by a predetermined coding algorithm, and supplies decoded video signals. It includes a buffer memory for temporarily storing the coded video signals. 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 decodes the video signals.
