ABSTRACT:
A video decoder in which the video source clock is generated entirely in the digital domain is disclosed herein. By creating a virtual version of the source clock in a numeric oscillator, the amount of noise in the system is substantially reduced. Furthermore, by transferring the digitized video signal, sampled with an asynchronous crystal clock, into the source clock domain, the accuracy of the brightness (amplitude) and color (phase) information can be greatly enhanced.
