ABSTRACT:
Disclosed is a system and method of dual-screen interactive digital television (IDTV), which is implemented by applying modality-independent remote console technology. The system has two ends, referred to as host IDTV and handheld device. The host IDTV includes a host IDTV content, an IDTV middleware, a host graphic user interface (host GUI), and a server-side remote console control protocol. The handheld device includes a handheld IDTV content, an interface generator, a handheld GUI, and a client-side remote console control protocol. In the invention, the DTV content may only have a dual-screen execution mode. The DTV content may also switch between single-screen and dual-screen modes.
