摘要
在解读MPEG-4标准文档的基础上,首先分析了MPEG-4的DPCM/DCT视频编解码器混合模型及其设计与实现,具体的对编解码算法中运算大的部分运动估计、变换和编码进行了深入研究,并探讨了编解码器中的每一个功能模块的设计可能对整体的计算复杂度和压缩性能造成极大的影响并给出了折衷方案。
Based on reading the documents of MPEG-4 standard, the DPCM/DCT CODEC model for MPEG-4 and its design and implementation are analyzed in detail. Specifically, deep research is conducted to motion estimate, transform, and encoding on the part of the encoding/decoding algorithm that calculate great, and explores significant effects on computation complexity and compression performance caused from design of every function module and their compromised plan.
