Abstract

The simple automatic repeat request (ARQ) scheme, error concealment by command refreshment, appropriate queuing discipline and priority switching design, layered source coding schemes, and other signal processing techniques are summarized with emphasis on different layered source coding schemes. Four types of signal priority classification schemes are identified: bit-plane separation (BPS), frequency-domain separation (FDS), combined bit-plane-frequency separation (CBFS) and feature plane separation (FPS). CBFS is shown to offer a good alternative to the FDS for possible cell dropping compensations in the ATM network. Different layered source coding schemes are described and compared, and a CBFS-based combined-transform coding (CTC) scheme is highlighted.<>

宽带ISDN环境下的可变比特率视频传输

总结了简单自动重复请求(ARQ)方案、通过命令刷新隐藏错误、适当的排队规则和优先级切换设计、分层源编码方案等信号处理技术，重点介绍了不同的分层源编码方案。确定了四种信号优先级分类方案:位平面分离(BPS)、频域分离(FDS)、位平面频率联合分离(CBFS)和特征平面分离(FPS)。在ATM网络中，CBFS为可能的cell丢失补偿提供了FDS的一个很好的替代方案。对不同的分层源编码方案进行了描述和比较，重点介绍了基于cbfs的组合变换编码(CTC)方案。
