Design And Implementation Of STB Base On Embedded System

With the development of digital and information technology, digital TV will be popular in the TV industry. Many foreign companies all want to occupy the digital TV market and have already released their digital TV set top box products. Under such a circumstance, it is very important for us to own the intellectual property right of the digital TV set top box. It's a very valuable project if we do some research in the procedure of the development of the digital TV set top box which is a embedded system. We can accumulate the experience in design and development pattern of embedded systems. This will make a foundation for our future research in embedded system. This article takes the digital TV set top box as an example. Based on the method in designing and building the hardware and the software platforms of the embedded system, it introduces the basic theory of embedded systems and digital TV technology. Then is. The development of the TV set top box is described as a model of developing an embedded system. The details of developing an embedded system will be given. After that we will introduce CA subsystem of the digital TV set top box, which is associated with how to charge the digital programs. I hope by this kind of means we can discuss from the architecture to the details of designing and realizing the digital TV set top box system.
