METHOD, DEVICE AND SYSTEM FOR ESTABLISHING MULTI-CASCADE CHANNEL

摘要

Disclosed are a method, device and system for establishing a multi-cascade channel. The method comprises: receiving a conference place code stream acquisition request, the request comprising at least one conference place identifier; receiving an address and a port corresponding to the conference place identifier; in accordance with the coding information about conference place code streams identified by the conference place identifier and the address and the port corresponding to the conference place identifier, establishing a multi-cascade channel for transmitting the conference place code streams identified by the conference place identifier; and sending the conference place code streams identified by the conference place identifier through the multi-cascade channel. The present invention solves the problem in the prior art that not all the conference place code streams which are expected to be obtained are obtained when the number of multi-cascade channels needed for obtaining code streams exceeds the number of specified multi-cascade channels because the number of multi-cascade channels must be specified before a conference, and achieves the purposes of dynamically establishing a multi-cascade channel as required and obtaining all the conference place code streams which are expected to be obtained.
