<P>PROBLEM TO BE SOLVED: To provide a content transmitter and a content receiver capable of dynamically switching the presence/absence of the application of error correction processing, in contents distribution of video images and sound, etc., utilizing an IP network. <P>SOLUTION: The contents transmitter 100 sets information indicating whether or not FEC processing is under execution to multiplex constitution information (PMT) cyclically arranged in TS and sends out content signals to the IP network. In the meantime, the contents receiver 200 separates the multiplex constitution information from the contents signals inputted from the IP network, analyzes it, discriminates whether or not the FEC processing is under execution, and executes FEC error correction decoding when the FEC processing is under execution. <P>COPYRIGHT: (C)2007,JPO&INPIT |
