The Application Of Digital Set Top Box

As broadcast TV is transitting from analog to digital in a high spread speed, a transitional product, the digital television receiver will access thousands of households. This thesis is a summary for my late two-year work experience, which expatiates on the development process of digital TV and the development actuality of digital Set Top Box. Base on the easy instruction of digital TV system, the thesis summarizes the digital TV developing trend and analyzes the differences of various modulation techniques. Here focus in introducing my design the digital television receiver (STB) hardware development platform which bases on DVB system.This thesis investigates the DVB system of digital TV product development. Following are the main investigation and finish items:1. The investigation on the circuit, principle and related digital TV standard.2. The investigation on the features of the main IC, confirm the functions of this solution, make the design layout of total block diagram and each module.3. Introducing the processing in two channels DVB-C and DVB-T, and the channel modulation hardware and software working flow.4. Introducing the main standard and system block diagram of MPEG, focus on expatiating on the system composing, working principle, MPEG-2 decoding signal flow and the implementation method of whole software system.Finally, summarize the development platform and introduce the method to solve the issues which should be taken into account when mass production.
