Research And Design Of Digital Set Top Box Based On TMS320DM6446 Media SoC

With the rapid development of information technology, the revolution has become inevitable from the traditional simulation television to the digital television. The digital television will take us the brand-new visual impact and the unprecedented large capacity information resource. Our country is also experiencing the television digitization transformation at present. According to our national condition, the digital television set-top box become in section of times to the digital television transition. So the cable TV numeral set-top box will certainly become the leading product in our country digital television set-top box. Therefore it have important significance to research the software system of cable TV numeral set-top box , the development and the design realization.Embodied system become a new technological development direction after the network technology, because its the volume small, the performance strong, the power loss low, the reliability and the profession application prominent characteristic, at present, embodied system apply widely electron, the network correspondence, the industry control and so on. The information contains computer technology, the communication, the semiconductor technology, the data transmission processing technology , even sensor technology, becomes the most dazzling in the applitional domain of embodied system .so the set-top box system is the most typical application in the information Domestic electric appliances. This article based on the TMS320DM6446 digital multimedia SOC's set-top box development project,...
