Patent ID: 7151575

Claim:
A wireless extension for transmitting analog and digital television signals from one location to another comprising: a sending unit comprising: a remote control interface for receiving a channel selection command; at least one tuner for receiving both analog and digital television signals responsive to the remote control interface with an RF input and a tuner output; a digital demodulator for receiving the tuner output and producing a digital stream containing MPEG encoded program information; an MPEG demultiplexer for receiving the MPEG information from the digital demodulator and selecting at least one MPEG program to produce a first MPEG stream; an MPEG encoder receiving the tuner output and producing a second MPEG stream; a selector for selecting between the first MPEG stream and the second MPEG stream, wherein an active MPEG stream is selected; a digital lock detector in the digital demodulator for detecting a digital signal lock condition; an analog lock detector in the MPEG encoder for detecting an analog signal lock condition; control logic circuitry responsive to the digital lock detector and the analog lock detector with an output to the selector to select an active MPEG stream from the stream indicating a lock condition; and a modulator and transmitter for producing an RF signal to transmit the selected MPEG stream; a receiving unit comprising: a receiver for receiving the RF signal; and an MPEG demultiplexer/decoder for demultiplexing the desired program and converting the MPEG program to a signal suitable for driving a television receiver.
