Patent ID: 7584494

Claim:
A cable to wireless conversion system for distributing video signals by wireless in-home transmission to a remotely positioned TV set, comprising: a base transmitter unit comprising a TV tuner, an input switch, a video transmitter, a base video antenna, a base control antenna, a base control receiver, a base unit display, and a CPU, said TV tuner being operable to select a channel from among a plurality of channels contained in a cable TV signal, said input switch being operable to select one of a plurality of video signals received from a plurality of video sources including said TV tuner, said video transmitter and said base video antenna being operable to transmit the selected video signal via a wireless broadcast of radio signals in the 2.4 GHz frequency range on one channel and broadcasting continuously; a remote receiver unit comprising a remote video antenna, a video receiver, a video out port, an IR receiver, a remote control transmitter, and a remote control antenna, said remote video antenna and said video receiver being operable to receive the video signal broadcast by said base transmitter unit and pass the video signal to the video out port for input to the remotely positioned TV set; a handheld remote control unit comprising a set of input buttons, a CPU, a memory, and an IR emitter, said remote control unit being operable to generate and emit IR control signals for sending to the base transmitter unit via the remote receiver unit; said IR receiver of the remote receiver unit being operable to receive IR control signals from the remote control unit, and said remote control transmitter and remote control antenna of said remote receiver unit being operable to broadcast the control signals to the base transmitter unit for controlling the video source selection of the input switch and the channel selection of the TV tuner, said IR control signals being broadcast in the 2.4 GHz frequency range and broadcasting intermittently on a channel different than said one channel; and means for repeatedly tuning the video transmitter and the video receiver to one same frequency and then changing the one same frequency to another same frequency that is different from the one same frequency; and wherein said remote receiver unit comprises a signal strength indicator operable to measure a strength of the video signal received from the base transmitter unit, said signal strength indicator having a first output connected to the remote control transmitter for transmitting a control signal indicative of said signal strength back to the base transmitter unit for displaying a value of the signal strength on said base unit display, and said signal strength indicator having a second output connected to the video out port of the remote receiver unit for displaying a value of the signal strength on the remote TV set when the remote receiver unit is placed in a signal strength mode.
