PACKETIZED ELEMENTARY STREAM RECONSTRUCTION APPARATUS FOR INTERFACE BETWEEN ENCODER AND MULTIPLEXER

摘要

PURPOSE: A PES(packetized elementary stream) reconfiguration device for interface between an encoder and a multiplexer is provided to simplify control circuit and to stabilize system operation by correcting system timing clock data error generated in the transfer from the encoder to the multiplexer. CONSTITUTION: An extractor(31) extracts an elementary bit stream clock reference data from a PES input from an encoder. A clock generator(34) generates a time stamp data. A comparator(33) compares the elementary bit stream from the extractor(31) and the time stamp data from the clock generator(34) and outputs the difference. A reconfigurator(32) constructs packetized elementary bit stream from the extractor(31) and corrects the decoded time stamp data by the difference value input from the comparator(33).
