【摘要】：随着信息技术的进步，视频监控已朝着高清、多路方向发展。基于通用DSP和H.264/AVC视频编码标准的实时视频压缩系统，可以为新的需求提供解决方案，因此研究基于通用DSP、采用先进视频压缩技术的实时视频编码器具有重要意义。本文首先介绍了视频压缩编码的发展和国内外现状，重点研究了目前广泛使用的H.264/AVC视频编码标准，在对比当前视频压缩编码硬件实现方案的基础上，提出了采用DSP硬件结构实现基于H.264/AVC视频编码标准的多路高清压缩方案。本文系统基于TI的新一代多核DSPTMS320DM8168芯片，给出了方案的设计与实现，在该系统上实现了H.264视频编码算法，可对输入的双路1080p视频进行实时编码压缩。本文提出的方案的主处理器只需一片DSP，，与传统多路视频压缩方案需要多片处理器相比，这种高度集成方案降低了部件数量和物料（BOM）成本、功耗需求，缩小了PCB尺寸，提高系统集成度。
[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.
