The problem of receiving dvb - c transport stream and playing in the pc has been completely solved . so there is a project provided for the tv stations to broaden scope of their data businesses 论文工作解决了基于pc机的dvb - c数据接收和实时处理问题,对拓展有线电视数据业务提供了一种很好的途径。
In the beginning , the dissertation gives an overview of digital video system and an introduction of the format of mpeg - 2 transport stream , mpeg - 2 physical interface and frame structure of ds3 stream 文章首先介绍了关于数字电视系统的一些基本概念, mpeg - 2传送流格式和mpeg - 2的物理接口,以及ds3码流的帧结构。
The traditional transport stream detector is based on the pc platform . the price is expensive and the operation is inconvenient . to solve this promblem , a design scheme based on sopc is proposed in this dessertation 传统的码流分析仪都是基于pc硬件平台的,价格昂贵,操作不便,无法满足低成本和较好的移动性的要求。
Mpeg - 2 transport stream multiplexer takes an important role in hdtv system . its performance has a great influence on the program transmission ability of hdtv system and the decoding quality of decoder in hdtv receiver Mpeg - 2传送流复用器是hdtv系统的重要组成部分之一，它将多路节目传输流复用成一个多路节目的传输流。
This thesis discusses the implementation algorithms and hardware structure of transport stream multiplexer . the main contents of this thesis are at a glance : chapter 1 gives an overview of dvb and atsc transmission standards 本文探讨了传送流复用器的实现算法和硬件结构，主要内容如下：第一章简要介绍了数字电视系统的两大标准。
The author of this dissertation has realized a transport stream detector in altera ’ s nios development board ep2c35 and this transport stream detector has a good performance . the basic analysis and monitoring has already been realized 论文作者已经在altera的niosiiep2c35开发板上实现了该性能良好的码流分析系统,可实现对码流的基本的分析与监测。
In the experiment , a mpeg - 2 ts ( transport stream ) file is segmented and transmitted to the pc with another ip address using windows system . all this is useful for implementing the dvb receiving on pc through cable modem 利用socket将mpeg 2传输流文件经切割后转发到以windows系统为平台的pc机上，在pc机上则通过directshow编程对此数据进行解码。
Mpeg - 2 standard is specified to meet the increasing need of the digital storage media , interactive television , high - define television and etc . mpeg - 2 standard defines two data structures , i . e . , transport stream ( ts ) and program stream ( ps ) Mpeg 2标准是为了满足对诸如数字存储媒体，电视传播以及通信等应用中对运动图像及相关音频一般的编码方法的日益增长的需求而制定的。
In this dissertation , the dvb technology , which is based on mpeg - 2 , and dvb - ci standard are firstly introduced . then the multiplexing of mpeg - 2 transport stream , psi / si and the multicrypt technology in conditional access are described in detail 本文首先介绍了基于mpeg - 2的dvb数字电视广播技术,着重阐述了mpeg - 2传送流复用, psi和dvb - si信息,以及条件接收技术中的多密技术。
This thesis introduce the pricipal of transport stream multiplexing / demultiplexing which is based on mpeg - 2 / dvb sysytem specfications for broadcasting , and discuss the implementation algorithms of transport stream multiplexer , and describe design and implememtation 本文研究了基于mpeg - 2和dvb标准上的传输流复用解复用的原理，探讨了传送流复用器的实现算法，并且给出一种实现的方案。
