The intelligent STB - implementation of next generation of residential gateway in digital home

As the core of digital home, RG(residential gateway) distributes services to diverse electronic appliances through different mediums. In this paper, we propose a new solution using a more intelligent STB(set top box) to fulfill tasks of RG. On the one hand, it integrates the two equipments together to cut the costs; on the other hand, it provides much more functions with good quality. We adopt the two-CPU architecture to satisfy powerful computing demands. Upon it the middleware is indispensable due to the heterogeneity of home network. Then, abundant embedded applications at the top accomplished the ultimate tasks successfully. By the way, this intelligent STB is nominated RG-STB.
