摘要
对几种视频差错控制技术进行了概括与比较,总结了前向纠错算法的基本原理及其优缺点。重点讨论了几种改进的前向纠错算法,包括动态前向纠错机制、自适应模型、主观质量控制策略和组播环境中的前向纠错方法。
Introduced and compared several error-control techniques during video transmission.The basic principle as well as the advantages and disadvantages of forward-error-correction are discussed.The emphasis is on several improvements of FEC,including dynamic FEC mechanism,self-adaptive modal,subjective quality control and the FEC in multicast environment.
