Patent ID: 7139319

Claim:
A method for transmitting and receiving an uncompressed HDTV signal over a wireless RF link, comprising the steps of: providing a stream of regenerated data having a first data rate of 1.485 Gbps from the uncompressed HDTV signal; providing a first clock signal using edge detection of said stream of regenerated data to generate said first clock signal synchronized to said stream of regenerated data; encoding said stream of regenerated data using a forward error correction code, producing a stream of encoded data having a second data rate higher than said first data rate by a coding overhead of said forward error correction code; providing a second clock signal using a PLL to generate said second clock signal synchronized to said stream of encoded data, said second clock signal having a rate higher than said first clock signal by said coding overhead; demultiplexing said stream of encoded data, using said second clock signal, into an in-phase (I) data stream and a quadrature (Q) data stream; QPSK modulating an IF carrier by said I data stream and said Q data stream; up converting said IF carrier to an RF signal; transmitting said RF signal over the wireless RF link; receiving said RF signal over the wireless RF link; down converting said RF signal to an IF frequency carrier having frequency greater than 1.5 GHz and less than 6 GHz; demodulating said IF frequency carrier so that said I data stream and said Q data stream are recovered; generating a third clock signal from said recovered I data stream and Q data stream, said third clock signal synchronized to said recovered I data stream and Q data stream; multiplexing said recovered I data stream and Q data stream, using said third clock signal, into a single stream of encoded HDTV data; and decoding said single stream of encoded HDTV data, using said third clock signal, so that the uncompressed HDTV signal is recovered.
