Interactive television (ITV) as a new form of TV programs has become a direction of broadcast trade development, at the same time the study of the interactive set-top-box has become the focus recently. This paper introduces an interactive set-top-box system. Firstly, the hardware and software architectures of the system are introduced generally, then several key parts of the system are described in detail. The system has been gone into testing in the CCTV's interactive television broadcasting project, and meets the anticipative design requests.
