<P>PROBLEM TO BE SOLVED: To provide a technology capable of executing on-time viewing or the like while transferring stream data. <P>SOLUTION: A stream data transmission management means 0106 and a stream data reception management means 0206 manage stream data transmission reception. The stream data transmission management means 0106 and the stream data reception management means 0206 check whether or not packets of transmitted stream data are correctly received or whether or not the stream data are high quality stream data, and store the packets when the packets of the transmitted stream data are not correctly received or when the stream data are not high quality stream data. The packets not received yet or the packets not being high quality packet are re-transferred through highly reliable stream data transfer. A transmission stream data management means 0102 and a reception stream data management means 0202 manage the stream data. For example, when the storage period of the stream data stored in a stream data reception system expires, the stream data are deleted. <P>COPYRIGHT: (C)2007,JPO&INPIT |
