<p>A system and method is 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 include complex streams such as multiple television 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 be 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 (10) with a motion picture display and hardware or software enabling interaction between a primary display (80) and the hand held display (10). The hardware may include an integrated TV tuner or a physically separate base station (75) having a TV tuner, in which case the base station (75) and the remote control (10) would communicate via radio frequencies (110 and 115).</p> |
