When transmission video over an open network , like the internet , the system usually has no central on dynamically changing and unpredictable network traffic 当在一个开发的网络(如internet )中进行视频传输时，通常难以避免误码和因网络拥挤而产生的丢包。
H . 26l is a video coding standard proposed by itu and iso / iec , it is the emerging standard for video communication and multicast in low bit rate conditions 在众多的视频编码标准中， h . 26l是由itu和iso / iec联合制定的面向无线通信和多播的低码率视频传输标准的最新版本。
To ensure to get the qos and reduce the effect of error in the video transmission , we should do error reconstruction in the process of video transmission in order to it 为了保证视频传输的服务质量,需要在视频传输的过程中进行差错控制,以此来降低差错对视频传输的影响。
Secondly , a new diamond search ( ds ) algorithm for fast block - matching motion estimation is implemented . we also map some of the instructions onto inteps mmx architecture 视频质量是衡量视频传输服务质量的重要指标，而对其的评价是一个与人眼视觉特性密切相关的过程。
By this , video . net , a network video transmission application software , has been developed . it can realize network video direct brodcast and get better effect in actual application 由此开发的网络视频传输应用软件video . net ，可以实现网络视频直播，在实际的应用中取得了较好的效果。
After briefly introducing the correlated technical basis of analog wireless video transmission system , the paper mainly focuses on the theory of oscillator and pll ( phase lock loop ) 论文首先简要介绍了模拟无线视频传输系统的相关技术基础,然后着重讨论了振荡器和锁相环的相关理论。
It successfully multicasts streaming avi , and the real time display quality at receiver is quite ideal . ? asms can be widely used in network education and other internet services ? asms可以从很大程度上解决网络远程教学中的视频传输问题，并且也可广泛应用于其它的多项互联网信息服务。
Thirdly , about rate control during video transmission , this thesis analyzes several control methods and ideas , puts forward an rtp - based source video transmission control policy ( 3 )针对视频传输中的速率控制，本文分析了几种控制方法和思路，提出了一种基于rtp的源端视频传输控制策略。
After briefly introducing cofdm technology theories , its major advantages and shortcomings , this thesis focuses on the whole design of cofdm - based clear video transmission system 文中介绍了cofdm的技术原理、主要优点及存在的不足,重点讨论了基于cofdm技术的清晰视频传输系统的整体设计。
There are spatial and temporal scalability simultaneously in three - dimensional wavelet transformation for sequence pictures , it is one of best video encoding methods in network video 视频序列图像的三维小波变换压缩，同时具有空间和时间的内在伸缩性，是网络视频传输的理想编码方法之一。
