Abstract:
The paper is dealing with the algorithm of low-bite rates aiming at ITLs high demand for audios QoS and large scaled realtime interactivity,as well as the problems existing in the present system.The algorithm can realize adaptive transaction of lowbite rates when the condition of the network changing.It can also provide strong support for the realtime group audio interactivity with adaptive regulation of QoS.
摘要： 针对视音频处理的实时授课系统在语音方面对QoS服务质量和大规模网上群体实时交互的高需求及现有系统存在的问题，设计了低比特率音频处理算法。该算法可以实现网络状况进行自适应的低比特率音频处理，为带QoS自适应调节机制的实时群体语音交互提供了有力的支持。
