  • H264AVC的CAVLC编码算法研究及FPGA实现.rar

    H.264/AVC是国际电信联盟与国际标准化组织/国际电工委员会联合推出的活动图像编码标准,简称H.264。作为最新的国际视频编码标准,H.264/AVC与MPEG-4、H.263等视频编码标准相比,性能有了很大的提高,并已在流媒体、数字电视、电话会议、视频存储等诸多领域得到广泛的应用。 本论文的研究课题是基于H.264/AVC视频编码标准的CAVLC(CONTEXT-based Adaptive Variable Length Coding,基于上下文的自适应可变长编码)编码算法研究及FPGA实现。对于变换后的熵编码,H.264/AVC支持两种编码模式:基于上下文的可变长编码(CAVLC)和基于上下文的自适应算术编码(CABAC,CONTEXT-based Adaptive BinaryArithmetic Coding)。在H.264/AVC中,尽管CAVLC算法也是采用了VLC编码,但是同以往标准不同,它所有的编码都是基于上下文进行。这种方法比传统的查单一表的方法提高了编码效率,但也增加了设计上的困难。 作者在全面学习H.264/AVC协议和深入研究CAVLC编码算法的基础上,确定了并行编码的CAVLC编码器结构框图,并总结出了影响CAVLC编码器实现的瓶颈。针对这些瓶颈,对CAVLC编码器中的各个功能模块进行了优化设计,这些优化设计包括多参考块的表格预测法、快速查找表法、算术消除法等。最后,用Verilog硬件描述语言对所设计的CAVLC编码器进行了描述,用EDA软件对其主要功能模块进行了仿真,并在Cyclone II系列EP2C20F484的FPGA上验证了它们的功能。结果表明,该CAVLC编码器各编码单元的编码速度得到了显著提高且均能满足实时通信要求,为整个CAVLC编码器的实时通信提供了良好的基础。

  • The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the cod

    The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the coding (compression) of natural video images. The new standard [1] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding: CONTEXT-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC). This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic Coding is assumed.

    This book presents an insightful view of XML that places this emerging technology in the context of the ongoing Web revolution. Written for business and technical professionals, this book revals the true value of XML for distributed information systems. It explains how XML is transforming the way organizations manage data and build software systems details the opportunities the language offers for organizatoins that understand tis significance and potential impact and explains how XML and Web services reflect a fundamental shift in software construction-from monolithic applications to software based on the composition of simple parts.
