H264AVC的CAVLC編碼算法研究及FPGA實現.rar

H.264/AVC是國際電信聯盟與國際標準化組織/國際電工委員會聯合推出的活動圖像編碼標準，簡稱H.264。作為最新的國際視頻編碼標準，H.264/AVC與MPEG-4、H.263等視頻編碼標準相比，性能有了很大的提高，并已在流媒體、數字電視、電話會議、視頻存儲等諸多領域得到廣泛的應用。本論文的研究課題是基于H.264/AVC視頻編碼標準的CAVLC(Context-based Adaptive Variable Length Coding，基于上下文的自適應可變長編碼)編碼算法研究及FPGA實現。對于變換后的熵編碼，H.264/AVC支持兩種編碼模式：基于上下文的可變長編碼(CAVLC)和基于上下文的自適應算術編碼(CABAC，Context-based Adaptive BinaryArithmetic Coding)。在H.264/AVC中，盡管CAVLC算法也是采用了VLC編碼，但是同以往標準不同，它所有的編碼都是基于上下文進行。這種方法比傳統的查單一表的方法提高了編碼效率，但也增加了設計上的困難。作者在全面學習H.264/AVC協議和深入研究CAVLC編碼算法的基礎上，確定了并行編碼的CAVLC編碼器結構框圖，并總結出了影響CAVLC編碼器實現的瓶頸。針對這些瓶頸，對CAVLC編碼器中的各個功能模塊進行了優化設計，這些優化設計包括多參考塊的表格預測法、快速查找表法、算術消除法等。最后，用Verilog硬件描述語言對所設計的CAVLC編碼器進行了描述，用EDA軟件對其主要功能模塊進行了仿真，并在Cyclone II系列EP2C20F484的FPGA上驗證了它們的功能。結果表明，該CAVLC編碼器各編碼單元的編碼速度得到了顯著提高且均能滿足實時通信要求，為整個CAVLC編碼器的實時通信提供了良好的基礎。

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.
