Data processing method and data processing apparatus

摘要

A CODEC which is supporting both a TFO operation and tandem operation includes a homing signal to reset an encoding section and a CODEC for decoding the compressed code data output from the encoding section 5A is transmitted when the TFO condition is shifted to the tandem connecting condition. Also a signal noise alleviation processing section detects a frame synchronization bit and performs a signal noise alleviation process from the leading area of the encoding processing frame and outputs the result to the encoding section.
