查询词典 video bandwidth

Firstly, the thesis introduced the development of VOD, the background and meaning of the program, then the author introduced the associated technology, mainly including the feature of multimedia, video compression technology and the protocols SCTP and RTP. Considering the ambulant of host , fluctuation of bandwidth,high error rate data in wireless networks ,the author proposed some QoS strategy in the wireless networks such as RTP/SCTP protocol stack , connection control of the server, two buffers in the client end point.,TFC congestion control algorithms ,etc. Based these strategies, the team members gives the software and hardware solution of the wireless video-on-demand system and gives the main modules design of the software system. The system adopted the C/S structure including two parts: server and client ,using the Mpeg-2 which is apporiate for networks as the supported format. The thesis emphatically researches on the video-serving module of the server and the sink module, player module of client.

本文首先介绍了视频点播系统的发展现状、课题的研究背景和意义；接着对课题的相关技术进行概述主要包括了多媒体特点，压缩技术，传输协议SCTP以及RTP；针对无线环境的节点移动性，带宽波动性，数据错误率高等三大特点，作者研究设计了无线环境下的QoS策略：RTP/SCTP协议栈，服务器准入控制机制，客户端双缓冲区，TFRC拥塞控制机制等；在这些策略的基础上设计了系统的软硬件解决方案，并对软件体系结构的主要模块进行了设计，整个视频点播系统采用C/S结构，由服务器，客户端2个部分组成，使用适合网络传输的流媒体格式Mpeg-2作为系统支持的格式，文中重点研究了服务器的视频服务模块以及客户端的接收模块和播放器模块，并利用线程池技术对系统进行实现。

3G networks are expected to be starting in Europe and part of AsiaPacific by 2002, and in the US later. 3G will support bandwidth-hungry applications such as full-motion video, video-conferencing and full Internet access.

到2002 年，已有部分欧洲和部分亚太地区开始使用3G 网络，以后将在美国使用。3G 将支持占用大量带宽的应用程序，如全动感视频、视频会议和完全的Internet 访问。

The main objective of this project is to research and develop a novel and high efficient video codec framework based on wavelet techniques, especially to address the heterogeneousness of video networks, the fluctuation of transmission bandwidth and the diversity of video-stream receivers. The system will have some basic characteristics of the next video coding standard, such as high compression efficiency, high scalability and high error resiliency. This project will provide a software prototype of wavelet video codec with full scalability, construct a verification platform for wavelet video on demand service, and furthermore, design some VLSI IP cores of the key module in the codec system

本项目研究的主要目的就是着眼于下一代视频编解码标准的基本特征（高效压缩，高可伸缩，高容错），以小波技术为核心构建新型高效的视频编解码系统；特别针对当前视频传输网络的异构性，网络带宽的波动性以及用户视频接收终端的多样性，实现一个码流高度可伸缩同时兼顾压缩效率的小波视频编解码软件原型，并且构建基于异构IP网络的小波视频服务的技术验证平台；进一步还将基于VLSI技术，对小波视频编解码系统的关键模块进行IP核设计

Fast bandwidth for the application of the family, but also quite optimistic about the industry,"the development of broadband in the world's best countries - Japan's practice, to provide bandwidth for the bandwidth and then to develop more applications, In fact, as long as it is to provide high-speed data, voice, video services, reflect the triple play of services, users can bring."

对于百兆带宽下的家庭应用，也有业内人士颇为乐观，"以世界上发展宽带最好的国家--日本的做法来看，先提供带宽，然后再为这些带宽开发出更多的应用，事实上，只要是提供高速数据、语音、视频服务，体现三网融合的业务，就可以带来用户。"

So, depending on the band- width required to serve the video and the bandwidth available, it creates a buffer to hold enough video so that it can start playing back the video while it is downloading video to the buffer in the background.

它决定于播放视频需要的带宽和可以带宽，它创建一个缓冲区来保持足够的视频数据，因此它可以在后台线程下载视频到缓冲区的同时播放视频内容。
