H.264/AVC是ITU与ISO/IEC(International Standard organization/Intemational Electrotechnical Commission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。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。基于上下文的自适应二进制算术编码(Conrext-based Adaptive Binary Arithmetic Coding,CABAC)是H.264/AVC的两个熵编码方案之一,相对于另一熵编码方案-CAVLC(基于上下文的自适应可变长编码),CABAC具有更高的数据压缩率:在同等编码质量下要比CAVLC提高10%~15%的压缩率。CABAC能实现很高的数据压缩率,但这是以增加实现的复杂性为代价的。在已有的硬件实现方法上,CABAC的解码效率并不高。 论文在深入研究CABAC解码算法及其实现流程,并在仔细分析了H.264/AVC码流结构的基础上,总结出了影响CABAC解码效率的各个环节,并以此为出发点,对CABAC解码所需中的各个功能模块进行了优化设计,设计出一种新的CABAC解码器结构,相对于一般的CABAC解码器,它的解码效率得到了显著提高。论文针对影响CABAC解码过程的"瓶颈"问题一多次访问存储部件影响解码速率,提出了新的存储组织方式,并根据CABAC的码流结构特性,采用4个子解码器级联的方式来进一步提高解码速率。 最后,用Verilog语言对所设计的CABAC解码器进行了描述,用EDA软件对其进行了仿真,并在FPGA上验证了其功能,结果显示,该CABAC解码器结构显著提高了解码效率,能够满足高档次实时通讯的要求。

很多不同的厂家生产各种型号的计算机,它们运行完全不同的操作系统,但TCP.IP协议族允许它们互相进行通信。这一点很让人感到吃惊,因为它的作用已远远超出了起初的设想。T C P / I P起源于6 0年代末美国政府资助的一个分组交换网络研究项目,到9 0年代已发展成为计算机之间最常应用的组网形式。它是一个真正的开放系统,因为协议族的定义及其多种实现可以不用花钱或花很少的钱就可以公开地得到。它成为被称作“全球互联网”或“因特网(Internet)”的基础,该广域网(WA N)已包含超过1 0 0万台遍布世界各地的计算机。本章主要对T C P / I P协议族进行概述,其目的是为本书其余章节提供充分的背景知识。 TCP.IP协议 缩略语 ACK

DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image compression standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the International organization for Standardization (ISO) and International Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.
