<p><P>PROBLEM TO BE SOLVED: To provide a technology for supplementing packet loss by means of real-time streaming. <P>SOLUTION: A transmitter side packetizes the time series information subjected to high efficiency coding to produce a first packet stream, generates a second packet stream resulting from delaying each packet of the first packet stream by a prescribed time, multiplexes the first and second packet streams and transmits the multiplexed stream, and a receiver side receives the signal resulting from multiplexing the first and second streams, demultiplexes the multiplexed streams into the first and second streams, sequentially stores the first packet stream of a prescribed amount to a buffer, applies sequential control to the second packet stream to extract the payload, sequentially decodes extracted data to reproduce and output time series information, and acquires a related packet to a missing packet from a packet group in the buffer, to supplement the acquired packet for the sequential control processing, when a packet loss is detected in the sequential control processing of the second packet stream. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
