Examples
- In this paper , three method are proposed . the two among them are that the higher information transmission data rate will be given in the increasement of the signal transmitted power , and another is got through the compression of video signal data rate
论文提出了三种方法，即两种通过信号功率增加使信息传输速率提高的方法和一种压缩视频带宽提高数据传输速率的方法。 - Firstly , the paper compares v . 90 , modem , xdsl , isdn in their characters , difficulties , management and costs . finally , we choose to construct the h . 320 multi - media communication system based on n - isdn . secondly , in the theoretical part of the paper , the basic theory of h . 320 multi - media communication is introduced , such as the compression of video and audio data , h . 320 stack protocol and especially introduced the theory , relative protocol and the technique of access to the net of n - isdn
本文针对铜线接入技术应用的基础和现状，对v . 90 、 modem 、 xdsl 、 isdn等接入方式的技术特点、接入难度、运行管理和经济性等方面进行对比分析，结合接入的具体环境，通信需求和经济性等方面的特点，重点阐述了n ? isdn接入方案的可行性和“基于n ? isdn接入的h . 320多媒体通信系统”的实现方案。 - This paper also provides some background knowledge about sip and video conference , such as the sip framework , the history of voip and video conference , etc . this paper emphasizes on the implementation of sip terminal on the windows platform , including the realization of sip stack , the capture and compression of video and audio steams , rtp transmission of stream data , the working thread of sip terminal and the optimization of video codecs
本文在论述研究工作的同时也介绍了一些相关的背景知识如sip协议的框架、 voip和可视电话的发展历史等。本文重点论述了windows平台sip多媒体终端的实现，包括sip协议栈的实现、视音频流的采集、编解码和网络传输方案、 sip终端的工作流程、以及编解码器基于指令集的优化。
