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。

Also, there will be a video screening titled "Stardusted" curated by Clark Buckner selected from M17 (Mission 17) Video Archive, highlighting video works specific to the themes of this exhibition.

录像作品主要从Mission 17的M17录像档案中挑选，主要介绍与本次展览主题有关的旧金山艺术家录像作品。

And the on chip data memory is byte addressable double data buffer structure, so that the unaligned data load and store can be supported and data can be prepared by DMA engine concurrently with computing.Finally, a video application specific SoC platform design and optimize. In video SoC platform, the embedded RISC processor and EDO-SIMD video processing engine were integrated with the DMA and LCDC etc. IP based on AMBA SoC interconnection and dedicated communication channel.

在片上数据存储的设计中，采用了Byte可寻址的双data-buffer的策略，既可以支持内存的非对齐访问，又可通过DMA并发完成数据的搬运。3视频处理SoC平台的设计基于AMBA总线和主要处理引擎间专用信道的SoC互连，以嵌入式RISC处理器和基于EDO-SIMD指令体系的视频处理擎为核心，配以DMA和内存控制器等外设，构成了一个基本的异构多核视频处理SoC平台原型。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。
