摘要

There is provided a media transmitting/receiving method, a media transmitting method, a media receiving method, a media transmitting/receiving apparatus, a media transmitting apparatus, a media receiving apparatus, a gateway apparatus, and a media server apparatus, for preventing media quality degradation caused by packet loss. They comprise a connection call processing unit for exchanging settings of encoded data and redundant data stored in each packet, and a setting of at least any one of encoding bit rates of a sound encoding unit and a redundant data generating unit, between the media transmitting/receiving apparatus, and a sound decoding unit for decoding at least any one of the encoded data and the redundant data based on the setting of the encoding bit rate exchanged between the media transmitting/receiving apparatuses, wherein the encoded data and the redundant data are separated from each packet based on the setting of the data stored in the packets exchanged between the media transmitting/receiving apparatuses, and lost encoded data is compensated with the redundant data, and thereby degradation of the media quality is prevented even when the packet loss occurs in transferring media encoded data in the packets via an IP network.
