The Design And Implementation Of Receiver Systerm Based On DVB-C

With the high speed of development of Digital Video Broadcasting, Digital Video Set-Top-Boxes(STB) have entered more and more home. Whilst STBs are providing stronger and stronger founctions, and more and more various service, they have played a more and more important role in the home entertainment system.The thesis mainly discusses the design and the implementation of DVB-C Receiver. Mainstream Digital TV system standards and the development history of STB, and popularize of STB inland are introduced firstly, then it introduces the MPEG-2 standard and the European DVB standard briefly.Based on the comprehension to those standards, a specific solution of the DVB-C receiver are analyzed, including hardware platform, system frame, embedded Real-time operation system and software work flow. And then some important components are analyzed in detail: GUI used in this system and points of development of GUI in embedded system; design of PTI and problems solved during development of PTI, which captures the information other applications need from TS stream; the methord of module upgrading; implementation of EPG module based on DVB-SI.With the future of DTV, the trend that the STBs are becoming the information centers of digital home is presented, and the technique Middle-ware and bidirectional interaction which are accelerating the development.The DVB-C Receiver sample discussed in the thesis has been produced into markets, which is well estimated with advanced and stable functions.
