| Abstract: | As an interface between the television and Wide Band, IP STB(Set Top Box) based on the Internet protocol can achieve the interaction of digital content service between family television and Internet. This paper introduces an entire system-design solution of the IP STB based on the technology of Embedded System, and gives a system hardware solution based on the dual-core processor of ARM9 and DSP. It also put forwards a system software solution based on structural theory. This system has many advantages, such as high controllability, strong data-processing ability and good expansibility. |
