First of all , this thesis discusses the theory of video compression and the process of video compression . after this , it takes serverial pages to introduce the video coding standard mpeg - x and h . 26x serial standards 本论文首先详细介绍了视频压缩的原理和视频压缩的流程,然后介绍了视频标准mpeg系列和h . 26x系列。
All of these algorithms are used in soft designing . 4 . it describes the standard and video for windows kits , and introduces mechanism for digital video of digital camera before an application soft was designed 研究了数字视频标准以及vfw软件包的功能，分析了数码相机的视频采集芯片各部分的功能，开发了一个视频采集的软件。
Video technol . , apr . 1994 , 4 : 158 - 167 . 14 generic coding of moving pictures and associated audio information - part 2 : video , itu - t and iso iec jtc 1 , itu - t recommendation h . 262 and iso iec 13 818 - 2 mpeg - 2 我们的分析和试验表明： avs第7部分在移动视频的常见码率和分辨率下能够达到和h . 264视频标准的基本部分类似的效果，但是明显的降低了复杂度。
Blackfin533 is the new multimedia chip of ad incorporation . the study on h . 264 standard and its implementation on blackfin533 is important to the application of video techniques on embedded system Ad公司推出的blackfin系列dsp芯片是针对视频技术而开发的专门芯片,因此,研究h . 264视频标准并研究其在blackfindsp上的应用对视频技术在嵌入式领域的应用研究有重大意义。
The paper introduces the application background of monitoring system , then the following two chapters discusses the multimedia transmission , mpeg - 4 standard , network programming technology and directshow programming technology 本文首先介绍了监控系统的背景,然后用两章对于课题涉及到的多媒体通信技术、 mpeg - 4视频标准、网络编程技术和directshow编程技术的技术基础做出了简单的分析和介绍。
The transcoding technology can be divided into two types : one is to transcode the video stream from one format to another , which is called homogeneous transcoding ; the other is heterogeneous transcoding , that is transcode the compressed video from one standard to another 所谓的视频转码就是将一种格式的压缩视频数据处理成更适应于特定应用的另一种格式的压缩视频流。主要分为两大类，一类是在同一视频标准中转换，另一类是在不同标准间转换。
An effective method is required to protect the digital products . digital watermarking is such an effective method and it attracts many researchers , especially digital video watermarking . in recent years there are many digital watermarking techniques for popular video compression standards 数字水印技术作为数字产品版权保护的有效手段，成为多媒体安全研究的热点，其中视频数字水印成为近年来新的研究热点，有许多学者针对现有的国际视频标准提出了多种视频水印方案。
In compressed domain , we analyse the traditionary scene change detection algorithms that are based on the compressed streams of mpeg - 1 / 2 / 4 and introduce the newest standard of video compression : h . 264 / avc . on the basis of analyse of the new features of srteams of h . 264 / avc and theirs impact on traditionary scene change detection algorithms , a novel scene change detection algorithm on h . 264 / avc is proposed in this dissertation 在压缩域,在分析传统的基于mepg - 1 / 2 / 4码流的镜头边界检测算法的基础上,结合最新视频标准h . 264 / avc的码流新特性,提出了一种在h . 264 / avc码流上检测镜头边界的算法。
