Abstract
The invention relates to a multi-point audio transmission method and a device thereof. The method comprises that: a plurality of terminal logging requests provided with identification information are received, each logging request carries different identification information; different sound tracks are distributed for the terminals, and response messages of the logging requests are sent to the terminals; the audio data of the terminals are received and are processed by distributing different sound tracks for the terminals, then the processed audio data corresponding to the terminals are generated; the processed audio data and the identification information are made a hybrid encoding and are sent. By the method of receiving the logging requests provided with identification information and making a hybrid encoding to the identification information and the audio data, the multi-point audio transmission method of the invention overcomes the disadvantage that receiving equipment fails to determine the corresponding relation between the terminals and the audio data after the receiving equipment receives the audio data when the terminals simultaneously participate in the audio data transmission in the prior art.
