摘要
(Video Coding Experts Group)和MPEG(Moving Picture Experts Group)组织共同开发的新一代视频压缩编码标准,并于2003年被ITU-T正式公布于国际上。,,被称为ITU-T -4标准的第10部分。(、、MPEG-2和MPEG-4等)中编码功能模块组成没有多大差别,主要差别在于各个功能模块的细节。基于这些模块细节,,获得了优越的压缩性能。但是,,就显得格外吃力。
。。,。随着大规模集成电路技术的发展,FPGA以其并行的处理能力和流水作业能力越来越受到人们的关注。为了实现视频编码的实时化,。本文主要工作有两部分:
一. 研究帧内预测算法,提取出一种适合于硬件的快速算法。
二. 、整数DCT变换、量化、逆量化、逆整数DCT变化、重构等部分,并对这些模块进行了仿真、综合和时序分析,在Altera的FPGA中进行了测试,验证该系统的可行性。

Abstract
is a new standard for coding (compression) of natural video images, which is developed by the groups for these standards, the Motion Picture Experts Group (MPEG) and the Video Coding Experts Group (VCEG), and is officially released on international in March 2003. Compared to the early and MPEG coding standards, / AVC has a much better coding pressing performance, which is also called ITU-T and MPEG4 Part 10 of MPEG4. mon with earlier standards (such as , , MPEG-2 and MPEG-4),the is a little different from them in the basic functional elements ,and a much different from the in implementation of the function blocks in detail. Based on the details, is finalized whit plexity pression technology, and gets pressing performance. So, realizing the pression for software is especially difficult in real time,.
is using the hybrid coding ways of the transformation and prediction. Intra p
