摘要：A remote control system including a hand held remote control unit (200) withan alphanumeric information display (209), for controlling and communicating with a firstcontrolled device (100), such as a digital music tuner connected to a community antennatelevision (CATV) cable, and for controlling a selected one of a plurality of secondcontrolled devices (300), such as CATV set-top-units, VCRs, or televison sets. A first, highspeed, error free display information communications protocol is utilized for transmittingprogram content or other information from the first controlled device (100) to theremote control unit (200) for display. A second or control communications protocol isutilized by the remote control unit (200) for controlling the first controlled device (100)and a selected one of the second controlled devices (300). The first controlled device(100) utilizes a first clock signal embedded in digital music signals provided via the cable
to derive clocking signals for implementing the display information communicationsprotocol, resulting in an efficient, low cost electronic design.
