摘要

Media sending and receiving method, media transmission method and the media reception method of preventing the quality deterioration of the media with the occurrence of packet loss, the media transmitter-receiver, the media transmitting device, the media receiving device, the gateway device and the media server device are offered. The coded data where it possesses with the audio decoding section which the coded data and the redundant data with either decodes one little at least either setting, and the audio coded section and the redundant data generation departments of the coded data and the redundant data which are housed in each packet on the basis of the connected call processing section and the setting exchanges the setting of one coded bit rate between the media transmitter-receivers of the coded bit rate which is exchanged between the media transmitter-receivers separates the coded data and the redundant data from each packet on the basis of the setting of the data which is housed in the packet which is exchanged between the media transmitter-receivers, misses with the said redundant data assistantThe media coded data through the IP net, by , when it transfers with the packet, packet loss occurring, deterioration of media quality is prevented.
