A decoding device includes a first receiving section for receiving a data packets, a second receiving section for receiving a plurality of error correction packets which includes matrix configuration information regarding the plural data packets, a deciding section for deciding a number of packets to be accumulated to restore a lost data packet, based on the matrix configuration information, an accumulating section for accumulating the data packets received by the first receiving section in the number of packets to be accumulated, and a restoring section for, when a loss of any of the data packets received by the first receiving section is detected, restoring the lost data packet by using at least one of the data packets and the error correction packets.

Decoding device, decoding method, and media data delivery system

A communication system that can improve communication quality by accurately re-creating reproduction timing at the receiving end even at the time of receiving VBR data or in the case of the occurrence of a packet loss. A send rate recognition section recognizes a send rate from a time stamp. A memory stores data. A dummy data addition section adds dummy data for correcting the difference between a read rate set for reading out data from the memory and the send rate to the data written to the memory. A read clock generation section generates a read clock which is equal to the read rate. A dummy data removal section removes the dummy data from the data read out from the memory on the basis of the read clock.
