Cable High-definition Digital Set-Top Box Design And Implementation

As digital TV technology and other related technology continues to progress, cable television networks are digital, networked, industrialization development eventually cable television networks will become able to support multimedia, broadband integrated information network supports a variety of complex applications. Key equipment for digital set-top boxes to cable television networks.Firstly detailed definition of digital cable TV set-top box, function and application environment, focuses on a design based on the the ST program of high-definition digital set-top boxes and Implementation of process and related technology. The entire paper is divided into three parts to discuss.The first part briefly describes the basic conditions for the development of high-definition digital TV technology at home and abroad.Review of the second part of the main technology used in high-definition set-top boxes and technical standards, including DVB standard QAM modulation techniques, as well as HD codec technology and so on.The third part discusses the project team to design a high-definition set-top boxes and its implementation methods, including the overall design of the set-top box hardware platforms (including the specific implementation of the various modules and schematics) and software platform (including the hierarchy of the software, applicationthe main portion of the layer) of the specific realization process.Discussed the high-definition digital set-top boxes, in the design and technically advanced foreign technology to maintain synchronization has been applied in many parts of the country, its advanced nature and stability of authorized users.
