摘要
本文提出了一种基于子带编码的可变比特率分层编码新算法。它能充分发挥ATM网络传输的特点,并对信元丢失这一ATM网络的固有缺陷造成的图像质量的下降进行有效的补偿,从而实现高质量的稳定的视频通信。文中给出了编码算法、信元构成的方法以及计算机模拟结果。
This paper proposes a new variable-bit-rate layered coding algorithm based on zubband coding. It makes full use of the advantage of variable-bit-rate transmission of ATM networks and has the ability to compensate picture degradation caused by cell loss, thus a high quality stable video communication is realized. The coding algorithm, cell composition method and simulation results are given.
