【摘要】：隨著信息技術(shù)的進(jìn)步，視頻監(jiān)控已朝著高清、多路方向發(fā)展�；谕ㄓ肈SP和H.264/AVC視頻編碼標(biāo)準(zhǔn)的實(shí)時視頻壓縮系統(tǒng)，可以為新的需求提供解決方案，因此研究基于通用DSP、采用先進(jìn)視頻壓縮技術(shù)的實(shí)時視頻編碼器具有重要意義。 本文首先介紹了視頻壓縮編碼的發(fā)展和國內(nèi)外現(xiàn)狀，重點(diǎn)研究了目前廣泛使用的H.264/AVC視頻編碼標(biāo)準(zhǔn)，在對比當(dāng)前視頻壓縮編碼硬件實(shí)現(xiàn)方案的基礎(chǔ)上，提出了采用DSP硬件結(jié)構(gòu)實(shí)現(xiàn)基于H.264/AVC視頻編碼標(biāo)準(zhǔn)的多路高清壓縮方案。 本文系統(tǒng)基于TI的新一代多核DSPTMS320DM8168芯片，給出了方案的設(shè)計(jì)與實(shí)現(xiàn)，在該系統(tǒng)上實(shí)現(xiàn)了H.264視頻編碼算法，可對輸入的雙路1080p視頻進(jìn)行實(shí)時編碼壓縮。本文提出的方案的主處理器只需一片DSP，，與傳統(tǒng)多路視頻壓縮方案需要多片處理器相比，這種高度集成方案降低了部件數(shù)量和物料（BOM）成本、功耗需求，縮小了PCB尺寸，提高系統(tǒng)集成度。
[Abstract]:With the development of information technology, video surveillance has developed towards high-definition and multi-channel.The real-time video compression system based on the general DSP and H.264/AVC video coding standards can provide a solution to the new requirements. Therefore, it is of great significance to study the real-time video encoder based on the general DSP and the advanced video compression technology.This paper first introduces the development of video compression coding and the current situation at home and abroad, and focuses on the H.264/AVC video coding standard, which is widely used at present, and compares the current hardware implementation scheme of video compression coding.A multi-channel high-definition compression scheme based on H.264/AVC video coding standard is proposed using DSP hardware structure.Based on the new generation of multi-core DSPTMS320DM8168 chip of TI, this paper presents the design and implementation of the scheme. The H.264 video coding algorithm is implemented on the system, which can be used for real-time coding and compression of the two-channel 1080p video.Compared with the traditional multi-channel video compression scheme, the high integration scheme can reduce the cost of components and materials, reduce the power consumption, and reduce the size of PCB, compared with the traditional multi-channel video compression scheme, which requires only one DSP chip.Improve system integration.
