Secondly, on this foundation, this thesis summarises characters of podcast, such as freedom, easy taking, strong interaction, easy threshold, multidissemination and nonfinite dissemination, compared with traditional mediums like broadcast, television and internet television. And this thesis also puts forward that the podcast is a kind of medium of grass roots against traditions.

其次，在此基础上，本文在比较播客与博客、播客与传统广播电视、播客与网络电台和网络电视的过程中总结出播客的六大媒介特点，即自由、便携、互动性强、准入门槛低、多媒体传播、非线性传播等特点，提出播客是一种颠覆传统的草根媒介。

Focusing on three key issues of the efficiency of video transmission, reliability and friendship on nets, the paper conducts a deep analysis of the enhancement of the compression of video-coding layer based on H.264, the optimized assembly of the net matching layer and the ability to correct errors of the decoder and encoder. Take the package switch of IP Video information package as an example, the thesis focuses on the reflection process of the Internet RPT/UDP/IP acted on by H.264, illustrates the typica...

In the basis of comparing the developing projects on the optical interconnection networks, combining with the actual probability of realization, we proposed the scheme of free space optical crossbar interconnection network using spatial light modulator . This interconnect structure is the most powerful single level interconnect network with the characteristics of reconfiguration and non-blocking. It can achieve arbitrary point-to-point link. Even more has it the ability of broadcasting and funnelling.

在比较现有的光互连方案的基础上，结合具体的可实现性，本文提出了使用空间光调制器的自由空间光学交叉开关互连网络的方案，这种互连结构是功能最强的单级互连网络，具有可重构性和非阻塞性，不仅能实现任意点到点的连接，还具有广播和汇集的能力。
