Abstract

PURPOSE:To prevent the increase of errors caused by the dropout of frame synchronism, by securing the perfect detection for the frame synchronous code with the recording switch timing and the insertion of a special code. CONSTITUTION:The frame synchronous code is detected in a certain interval in the section during which no electronic editing is carried out. A synchronous protective gate is grown by a counter 506 to avoid the wrong detection due to a pseud opattern in a data. The pulse detected through a comparator 504 plus the pulse detected through an AND gate 502 are turned into the normal frame synchronous codes. When the frame synchronous pulse is obtained, the counters 506 and 508 are reset. Then the synchronous protective gate grown by the counter 506 functions effectively up to the electronic editing point.
