Busparallel expansion and pipeline technique are adopted to improve the average inputand output speed of recorder based on FLASH memory. 2 A concept of 'cluster' isintroduced. The using state message of each cluster is loaded in the spare area,following the target datum, to keep the pipeline sequence of multiple clusters' loading, which guarantee the average input speed of system. 3 Based on the using statemessage of every cluster, the Cluster Allocation Table established in memory enablethe system to manage the recorder flexibly in high speed, similar to a file managementsystem. 4 PowerPC 8245 based embedded system, along with Vxworks real-timeoperating system is introduced to make the system more easier to be applied to theprojects in the future.

本文所述的关键技术特点主要包括：采用了并行扩展以及流水线操作技术以提高基于FLASH芯片的存储区平均输入输出能力；引入了&簇&的概念，为了保证连续写入过程中的流水线顺序，系统向存储区加载每一簇有效数据后，紧接着还将向相应簇的空余区中加载该簇的使用状态信息；根据所有簇的使用状态信息在系统内存中建立&簇分配表&，可以支持系统快速灵活地管理存储区，即，类文件化的数据管理；采用基于PowerPC8245的嵌入式计算机硬件系统及基于Vxworks的嵌入式实时操作系统，提高了系统的整体性能及系统研发的延续性。

A video card , also called a graphics card or video adapter , converts digital output into an analog video signal that is sent through a cable to the monitor .

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。
