<P>PROBLEM TO BE SOLVED: To suppress a transmission delay occurring when a data packet is transmitted at a variable rate. <P>SOLUTION: A transmission device 1 includes a reception part 1a, an update part 1b, a generation part 1c, and a transmission part 1d. The reception part 1a receives a data packet or an error correction packet for restoring a data packet by error correction. A data packet includes protection range information, written thereto, for identifying a protection range of a data packet that can be restored by the error correction performed by the error correction packet. The update part 1b updates the protection range information of data packet(s) in order of the reception part 1a receiving data packets. The generation part 1c generates an error correction packet for a data packet identified by new protection range information in accordance with the update part 1b updating the protection range information. The transmission part 1d transmits both the data packet whose protection range information has been updated by the update part 1b, and the error correction packet generated by the generation part 1c. <P>COPYRIGHT: (C)2012,JPO&INPIT |
