Digital Satellite Television Receivers And Program Switch Design

Broadcasting network by satellite, with its wide frequency band and vast overlay acts as an excellent medium for the widespread of information. Concurrently,accompanied by this economic torrent with knowledge, a digital revolution breaks out , the rapidly developed Digital TV is replacing the analog TV gradually.The people's demands coming from the Digital TV's multimedia services based on DVB standard increase. Based on the design of DiSEqC and EMMA2L digital satellite receiver which adopting the NEC company EMMA architecture, the second generation enhanced multi-media architecture processor , this article summarizes the theories , the framework and each part's function of Digital Satellite TV receiving system at first. In succession, this thesis discusses the DiSEqC and STB of Digital Satellite TV receiving system design and implementation both on hardware and software. The main contents are as follows: 1. Contrived hardware of DiSEqC slave device 2. Proceeding the hardware design of the digital satellite receiver. 3. Design and implementation of OSD menu 4. Studied the DiSEqC bus transfer and control protocol ,designed the program of DiSEqC host device and DiSEqC slave device...
