PROBLEM TO BE SOLVED: To provide a new video transmission/reception technique by which error correction calculation can be independently executed for each picture without causing the increase of a transmission delay due to addition of an error correction code, the local changes of redundancy, and the increase of a calculation amount.;SOLUTION: An (n, k) error correction encoder variable of n, k values is used in a video transmitter. An independent error correction block is composed in units of each picture. The error correction calculation is executed by changing the values of n, k corresponding to a generated code amount per picture so as not to require the insertion of a dummy media packet during calculation. An FEC packet is generated and transmitted. By receiving the FEC packet, an (n, k) error correction decoder variable of n, k values is used in a video receiver. The recovery of a lost packet is executed in units of each picture by using the same values of n, k as those selected by the video transmitter.;COPYRIGHT: (C)2006,JPO&NCIPI
