<P>PROBLEM TO BE SOLVED: To transmit high quality video by avoiding abnormal operation even though delay occurs by retransmission or the like due to communication interruption and a communication error when performing synchronous transmission of a stream of a video signal, etc., by a radio transmission method of IEEE802. 11 or the like. <P>SOLUTION: A transmission side transmits data with a time stamp attached to video data. In a receiving side, a time stamp checking part 0819 for adding a time longer than a time required for radio communication to a time stamp added to received data and comparing the added time stamp is made to have a function for discarding data regardless of a time stamp value, and a data discard control part 0826 is newly provided for instructing the time stamp checking part 0819 to discard data for as much as a set time from a time when a data transmission start is detected. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
