Various interactive services become a pillar of the whole industry. Especially, EPG system and EPG increment services have changed people's life in some respects.The thesis mainly discusses the design and implementation of EPG system, NVOD system and data broadcasting system based on the DVB-C platform. Specially, this thesis pays much attention to the core of DVB-C Set-Top-Box software: demultiplexer. The developing history of cable digital TV and its current situation and developing trend are introduced firstly. Then relevant standards and theory technologies are introduced. Specially, it introduces relevant standards of EPG.Then the framework of the demultiplexer and its flow chart of EPG system based on DVB-C are introduced in detail, and the supports of STi5518 platform are discussed. This thesis discusses the limition of demultiplexer of STi5518 platform, and it brings forward some methods to solve this problem.In the end of this thesis, this thesis gives a brief explanation of these hot services based on the demultiplexer. And it forecasts the technology development and the market situation of the digital TV market.
