<p>PURPOSE:To surely detect a continuous pattern by deciding comprehensively the results obtained from a monitoring means, a program searching bit detecting means and a bit train deciding means. CONSTITUTION:A deciding signal (g) and (h) outputted from a pre-stage bit train monitoring part 11, a post-stage bit train monitoring part 10 and a program searching bit detecting part 12 are all inputted to an integrated deciding part 13. On the other hand, in the program searching bit detecting part 12, the heat two bits among respective 8 bits of a second - a fourth memories (4-2)-(4-4) coincide with a program searching bit. In this case, from the integrated deciding part 13, a data latch signal (j) is sent out to a data latch part 14, and the data latch part 14 inputs in parallel the data of 6 bits except the program searching bit in 8 bits subjected to majority decision from a bit train deciding part 7. Subsequently, this data of 6 bits is outputted serially and successively as reproducing data (e) by a data reproducing part 15.</p> |
