【摘要】：数字视频压缩编解码技术作为多媒体技术的重要组成部分,发展迅速,产业应用也越来越广泛。目前国际上两大主流视频压缩编解码标准MPEG和H.26x,占据了视频应用领域的大半江山。AVS2数字视频压缩编解码标准是我国自主制定的代表着国内最高水平的视频标准,目前正处于发展阶段,并未进入产业化应用。本文就是对AVS2视频标准进行技术分析与优化改进,同时,在硬件平台上实现AVS2视频的快速解码。本文采用的硬件平台为德州仪器公司的TMS320C6678芯片,是一款多核DSP芯片。TMS320C6678拥有德州仪器公司最新的体系架构及较高的处理性能,已经被广泛应用在了各个领域,特别适合大数据量的多媒体处理工作,为本文实现AVS2视频的软件解码提供了硬件保障。本文的主要内容:首先对国内外的视频编解码技术的现状进行概述,着重介绍目前我国视频编解码技术的发展,详细分析AVS2视频编解码标准的关键技术。然后对开发平台TMS320C6678进行重点介绍。最终,详细介绍AVS2视频解码器在TMS320C6678平台上的应用开发,包括移植、优化、集成和联调。
[Abstract]:As an important part of multimedia technology, digital video compression coding and decoding technology is developing rapidly and its industrial application is becoming more and more extensive. At present, two major international video compression standards, MPEG and H.26x, occupy most of the video applications. AVS2 digital video compression and decoding standards, which are independently formulated by our country, represent the highest level of video standards in China. At present is in the development stage, did not enter the industrialization application. In this paper, the AVS2 video standard is analyzed and optimized. At the same time, the fast decoding of AVS2 video is realized on the hardware platform. The hardware platform used in this paper is the TMS320C6678 chip of Texas Instruments, which is a multi-core DSP chip. TMS320C6678 has the latest architecture and high processing performance of Texas Instruments, and has been widely used in various fields. It is especially suitable for multimedia processing of large amount of data and provides hardware guarantee for software decoding of AVS2 video. The main contents of this paper are as follows: firstly, the present situation of video coding and decoding technology at home and abroad is summarized, the development of video coding and decoding technology in China is emphatically introduced, and the key technology of AVS2 video coding and decoding standard is analyzed in detail. Then the development platform TMS320C6678 is introduced emphatically. Finally, the application and development of AVS2 video decoder on TMS320C6678 platform are introduced in detail, including transplantation, optimization, integration and combination.
