<p><P>PROBLEM TO BE SOLVED: To provide an FEC encoding method, an FEC decoding method, and an FEC decoding device that enable to avoid burst-like output, even when a supply density of packets temporally varies. <P>SOLUTION: Each payload respectively possessed by successively-supplied media packets is successively stored in a buffer memory. It is detected whether or not the number of the stored payloads reaches a specified number, or whether or not a time from the time when it is started to store the payloads in the buffer memory reaches a fixed time. If detected that the number of the payloads reaches the specified number, first information for an FEC is generated by executing an FEC operation by the specified number of the stored payloads. If detected that the time from the time when it is started to store the payloads in the buffer memory reaches the fixed time, second information for an FEC is generated by executing the FEC operation by using the payloads stored in the buffer memory. The first/second information is outputted together with the media packets corresponding to the first/second information. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
