Patent ID: 8644378

Claim:
A digital video communication device, comprising: a receiver configured to receive a spread-spectrum (SS) video signal time stamped with a plurality of frequency parameters, wherein the receiver comprises: a free-running clock generator configured to generate a reference clock signal; a line buffer coupled to the frequency synthesizer, the line buffer configured to: store pixel data of the SS video signal; determine a frequency ratio from the plurality of frequency parameters in the SS video signal, wherein the frequency ratio relates a stream clock frequency associated with the pixel data to a link symbol clock frequency associated with the SS video signal; adjust the frequency ratio to avoid overflow and underflow in the line buffer; and output the adjusted frequency ratio; a frequency synthesizer configured to generate, based on the reference clock signal and the adjusted frequency ratio, a read clock signal for the line buffer; and a video recovery device driven by the read clock signal generated by the frequency synthesizer and configured to produce a video output signal by reading the pixel data from the line buffer.
