Abstract
Systems and methods are disclosed for using two or more cooperating but physically independent displays for enhanced viewing of data streams, where the viewing on one display does not interfere with the viewing on the other displays. The type of data streams may be complex streams such as multiple television (TV) broadcast signals or other video signals, internet data, or other local data such as information related to the state of a consumer's home appliances. The signals may include data embedded in the vertical blanking interval (VBI) for analog signals, or in dedicated slots in a digital signal according to protocols such as MPEG. The system includes a hand-held and portable remote control with a motion picture display, and hardware and/or software enabling interaction between a primary display (such as a TV) and the hand-held display. The hardware may include an integrated TV tuner, or a physically separate base station having a TV tuner, in which case the base station and the remote control would communicate via radio frequency (RF).
