<P>PROBLEM TO BE SOLVED: To provide a media information distribution system and a media information distribution method that can attain compatibility between the real time performance of real time distribution and the high reliability of stored information at the multicast distribution of a media information stream (time series data). <P>SOLUTION: At multicast distribution using the Internet or an intranet and multicast information distribution using a digital broadcast satellite communication satellite, a data receivers 200a, 200b and 200c store distribution information, detect positions where transmission errors occur, request the other data receiver to re-transmit a transmission error portion and receive the information so as to correct a transmission error existing in the stored distribution information. This allows to satisfy both the real time performance of multicast program distribution and the high reliability of information storage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
