介绍了感知编码的一些基本概念,总结了早期错误弹性音频流的基本原理及关键技术,提出了一种感知编码的错误弹性音频流的改进方案,并对改进方案的仿真结果作了总结和分析.结果表明,提出的方案大大增强了增益因子丢包的鲁棒性.

This paper presents some concepts on perceptually coded. The principle and critical methodes of our earlier system are also summarized. Then novel extensions to our earlier system for streaming perceptual coded audio are proposed. This new scheme is applied into an RTP-based test system for performance evaluation. Simulation results have shown that the improved streaming system is more robust against pack...
