Patent ID: 8649300

Claim:
An audio data processing method for distributing audio streams in a conference system having a plurality of control servers for processing and directing audio streams and a plurality of terminals accessing respective control servers, the method comprising: receiving, by a first control server, coded audio data from a second control server and coded audio data from each terminal accessing the first control server; selecting, by the first control server for a target terminal accessing the first control server, coded audio data from the coded audio data received from the second control server and from the coded audio data received from each terminal accessing the first control server; and when audio capability of the target terminal indicates that the target terminal supports a multi-channel separation audio codec protocol through one audio logical channel, encapsulating, by the first control server, the coded audio data selected for the target terminal into at least one packet for transmission through one audio logical channel without decoding the coded audio data selected for the target terminal; and transmitting, by the first control server, the at least one packet to the target terminal; when audio capability of the target terminal indicates that the target terminal supports multiple audio logical channels, transmitting, by the first control server, the coded audio data selected for the target terminal through multiple audio logical channels to the target terminal without decoding the coded audio data selected for the target terminal.
