Massively Parallel Data Broadcasting System To Receive The Card

This paper states the concept and development history and standard and theory of data broadcast. Then presentes a new data broadcast system, i.e. that it is an enormous and parallel data broadcast system and receiver card which are research Aim.This project , an enormous and parallel data broadcast system, is based on the relevant theory of Li youping academician who works in China academy of engineering physics. In order to verify the theroys of Li whether correct or not and whether realizable or not, Jiuzhou company organized a research group leaded by Author. Aaccording to a great deal research work and academic analysis of Li's theoty ,Author have drew a conclusion : the best model for the theory of Li is the enormous and parallel data broadcast system (ab. EPDBS)。This paper represents the system structure of EPDBS, then analyzes the system structure the Source-end and Front-end and Trminal-end involved by this system structure. And showed the implementation of this system, including relevant routine of technique,UCL theory,and then expounded design diagram and of the system.Then,The most statement is about component of terminal receiver system, named data receiving Card, these introductions describes its design principle and implementation. For TCP/IP and UDP/IP protocols, IP broadcast and multi-broadcast, Ethernet technique and interface chips,relevant DVB technique (such as IP/DSM_CC/TS/DVB multi-protocol encapsulations and so on),IP datagram for encapsulating Ethernet datagram, PCI bus and interface chip,FPGA,Tuner and so on involoved by EPDBS are expounded in this disquisition. Use the FPGA technique to abstract and filter PID is TS stream.Then gave the design diagram,principle chart,module(or component) diagram, function diagram,routine flow chart and part of design code.of the receiving card.Finally, This paper presents some application field of EPDBS.
