一种与H.263建议兼容的会议电视分层编码方案
摘 要
在对运动图象序列的两类DCT系数进行统计分析的基础上，提出了一种与H.263建议完全兼容的会议电视分层编码方案。该方案独立于编码器，简单易行。实验表明该方案能以较少的图象质量损失在信道带宽降低时传送连续的图象序列，适用于基于计算机网络的会议电视系统。

A Scalable Coding Scheme for Videoconference Complied with H.263 Recommendation
() Abstract
Based on the schototics analysis of the two kinds of DCT coefficients, a scalable coding scheme complied with H.263 recommendation is proposed. This scheme is independent on the hardware and can be implemented easily and quickly, sending successive video signal within dynamically changeable bandwidth. Therefore it is suitable for the videoconference system running on the computer network.
