While traveling on planes or trains , people could enjoy streaming video input or interactive games on three - dimensional - vision eyeglasses and high - fidelity audio sets equipped with uwb 搭飞机或火车旅行时，只要配备有超宽频，人们可以戴上三维影像眼镜，打开高传真音响配备，欣赏以串流技术输入的影像，或是玩互动游戏。
Based the research background of the remote video surveillance which makes real - time and adaptive compression and streaming video sequence necessary , this paper first does the deep research on video compression and coding which is the hardcore part of mpeg4 mainly from two facets 远程视频监控要求对视频图像进行实时的压缩编码以及根据网络状况自适应地对压缩视频流进行流化传输，因此视频编码器必须能够进行快速的编码和比特率控制。
In this dissertation , some relative background knowledge is introduced in the beginning chapters , and then on the basis of synthetical analysis of the state of arts of streaming media transmission control , a universal streaming video transmission control method is proposed 本文首先介绍了各相关背景知识。然后在综合参考和分析了国内外流媒体传输控制方面的相关工作的基础上,以流媒体视频为研究对象,提出了一种通用的流媒体优化传输控制方案。
With the explosive growth of the internet and increasing demand for multimedia information on web , streaming video over the internet has attracted tremendous attention from the academia and industry in this paper , we discuss a architecture for distributed video server that have a good scalability , which the system can grow with users " requirement 互连网的快速发展和人们对多媒体信息日益增长的需求，使得视频点播技术的应用范围越来越广，同时也引起学术界和it行业的密切关注。本文论述了一种具有良好扩展性的分布式视频点播系统，它能有效地在较广地域内面向庞大的用户群提供点播服务。
When the digital streaming video is transmitted on internet , it will be affected by the network , such as bandwidth , so the paper also deals with streaming video watermarking and its exclusive requirement . at the last chapter , an object - based watermarking algorithm has been presented . the watermarking algorithm for mpeg - 4 compression is devoted to address the influence from the rate scalability , based on static texture object in mpeg - 4 and watermarking in wavelet domain 在此基础上针对视频与图像的异同点，分析比较了静态图像水印和视频水印特点的异同，并且结合在internet上传输视频时，网络自身的特性(比如带宽资源等)对视频流产生的影响，以及这些影响对视频流水印技术的特殊要求，结合基于对象的视频编码标准mpeg - 4的特性，提出了在视频对象中利用基于小波变换的水印方案。
In order to prove its feasibility and superiority , a segment of mpeg - 4 encoded streaming video is used for simulation . the experimental results and analyses show that this method outperforms the traditional ones that are based on the fixed token generation rate in the same condition of network throughput 通过选取的一段mpeg - 4编码的流媒体视频实验数据进行了仿真实验,通过实验结果数据的分析和对比可以看出,该控制方法在网络输出能力一定的条件下,比传统的人为设置固定的令牌产生速率的方法所达到的效果要好的多。
