【摘要】：數(shù)字視頻壓縮編解碼技術(shù)作為多媒體技術(shù)的重要組成部分,發(fā)展迅速,產(chǎn)業(yè)應(yīng)用也越來(lái)越廣泛。目前國(guó)際上兩大主流視頻壓縮編解碼標(biāo)準(zhǔn)MPEG和H.26x,占據(jù)了視頻應(yīng)用領(lǐng)域的大半江山。AVS2數(shù)字視頻壓縮編解碼標(biāo)準(zhǔn)是我國(guó)自主制定的代表著國(guó)內(nèi)最高水平的視頻標(biāo)準(zhǔn),目前正處于發(fā)展階段,并未進(jìn)入產(chǎn)業(yè)化應(yīng)用。本文就是對(duì)AVS2視頻標(biāo)準(zhǔn)進(jìn)行技術(shù)分析與優(yōu)化改進(jìn),同時(shí),在硬件平臺(tái)上實(shí)現(xiàn)AVS2視頻的快速解碼。本文采用的硬件平臺(tái)為德州儀器公司的TMS320C6678芯片,是一款多核DSP芯片。TMS320C6678擁有德州儀器公司最新的體系架構(gòu)及較高的處理性能,已經(jīng)被廣泛應(yīng)用在了各個(gè)領(lǐng)域,特別適合大數(shù)據(jù)量的多媒體處理工作,為本文實(shí)現(xiàn)AVS2視頻的軟件解碼提供了硬件保障。本文的主要內(nèi)容:首先對(duì)國(guó)內(nèi)外的視頻編解碼技術(shù)的現(xiàn)狀進(jìn)行概述,著重介紹目前我國(guó)視頻編解碼技術(shù)的發(fā)展,詳細(xì)分析AVS2視頻編解碼標(biāo)準(zhǔn)的關(guān)鍵技術(shù)。然后對(duì)開(kāi)發(fā)平臺(tái)TMS320C6678進(jìn)行重點(diǎn)介紹。最終,詳細(xì)介紹AVS2視頻解碼器在TMS320C6678平臺(tái)上的應(yīng)用開(kāi)發(fā),包括移植、優(yōu)化、集成和聯(lián)調(diào)。
[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.
