VOD系统及其机顶盒的研究
摘要
本文从我国有线电视技术的发展角度出发，提出了一种基
于大城市CATV网络的VOD系统方案，包括小区中心站的组成
模块、功能以及机顶盒的结构、功能，并通过TVOD和ANVOD
的动态组合来实现高质量的VOD业务;解决了VOD系统的几个
关键技术，包括VOD系统的有条件接收、MPEG-2在VOD上的可
靠传输、HFC网络上行通信的实现；在此基础上，给出了一种
实用机顶盒的硬件和软件结构，详细介绍了各集成电路芯片的
功能结构，并给出了机顶盒软件的部分程序流程图。为今后VOD
系统及其机顶盒的研究提供了一定的理论基础，也为今后正式
开发VOD系统及其机顶盒产品提供了有益的实践价值。
We bring forward the design of VOD services based on big city's
CATV network, including modules and functions in neighbor traffic
controller and set-top box, A VOD scheme dynamical combined with
TVOD and ANVOD is presented to provide video-on-demand services;
We also solve several key techniques in VOD system:conditional
Access of VOD service、Reliable transmission of MPEG-2 in VOD
system、HFC networks upstream communication;Moreover, we put
forward a kind of hardware and software architecture of STB design,
and introduce every integrated circuit chip's functions and
architecture, and describe partly procedure flowchart of STB's
software design;This provides proper theory foundation and useful
practice value for the research of VOD system and STB design.
