<P>PROBLEM TO BE SOLVED: To reduce the end-to-end delay time. <P>SOLUTION: This data distribution system is provided with a transmitter for transmitting a data stream via a network, and a receiver that receives the data stream, stores the received data stream to a reception buffer, and decodes the data stream stored in the reception buffer. The amount of data storage of the reception buffer which is sufficient for consecutively decoding a received data stream (consecutively decodable amount of data storage) is estimated in the network independently of variations of a data transfer time from the transmitter to the receiver. The receiver starts decoding the received data stream at a decoding rate lower than a decoding rate estimated at encoding in a period from the start of reception of the data until data equivalent to the amount of consecutively decodable data storage are stored. Further, the receiver revises the decoding rate into the decoding rate estimated at the encoding after the reception buffer has stored an amount of data equivalent to the amount of consecutively decodable data storage. <P>COPYRIGHT: (C)2004,JPO |
