摘要

Frame synchronizing signals held by a synchronization register 2 are Reed-Solomon-coded by a Reed-Solomon coding circuit 4, then interleaved by an interleave circuit 5, then convolutional-coded by a convolutional coding circuit 10, then mapped by a mapping circuit 11, and then outputted. Thus, the frame synchronizing signals can be stably and quickly detected.
