摘要：PROBLEM TO BE SOLVED: To improve reliability of detection of a synchronism code simplifying position detection of the synchronism code. SOLUTION: When a first pattern (e.g. sync-code no."2""1""0" in sync-frame no."00") consisting of combination of continuous three synchronism codes is compared with a second pattern (e.g. sync-code no."1""0""1 in sync-frame no."01") consisting of combination in which a position of the synchronism code is deviated from the first pattern by one piece, synchronism codes of two or more are varied.
