COMMUNICATION DEVICE, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent a computational complexity from abruptly increasing owing to FEC arithmetic processing.

SOLUTION: A communication method as an embodiment of the present invention includes: trying to receive a media packet from a network; storing the received media packet in a first buffering means; receiving an FPC packet including redundant data for restoring a lost media packet and information specifying a plurality of media packets related to the redundant data; storing the received EFC packet in a second buffering means; selecting the FEC packet from the second buffering means; and performing respective divided arithmetic processings, obtained by dividing an FEC arithmetic processing to be performed using the redundant data included in the selected FEC packet and media packets in the first buffering means associated with the redundant data into a plurality, one by one in order each time reception of the media packet is tried.
