RECEIVER FOR AN ERROR-PROTECTED PACKET-BASED FRAME, CAPABLE OF DRASTICALLY REDUCING THE LATENCY OF FEC DECODING AND THE SIZE OF A PACKET BUFFER

摘要

PURPOSE: A receiver for an error-protected packet-based frame is provided to have a latency smaller than an existing FEC(Forward Error Correction) decoder, thereby reducing the size of a packet buffer.;CONSTITUTION: A receiver(400) comprises a packet buffer(404), a play-out buffer(406), an FEC decoder(408), and an FEC cache(410). The FEC decoder processes each packet received in real time and stores each packet in the packet buffer. The FEC decoder generates intermediate FEC-processing results stored in the FEC cache. The FEC decoder keeps the intermediate FEC-processing results. The FEC decoder updates the intermediate results stored in the FEC cache.;COPYRIGHT KIPO 2011
