ABSTRACT:
A digital display unit receiving a display signal with image encoded at high origin frequencies (e.g., dot clock). A display signal interface samples the display signal during source display time to generate pixel data elements representative of the images encoded in the display signal. The signal is sampled at a sampling frequency equal to origin frequency. The pixel data elements are stored in a buffer at the sampling frequency and retrieved at a slower frequency. Display signals are generated for each horizontal scan line of a digital display screen during a destination display time at this slower frequency. The destination display time is designed to be longer than the source display time, which enables the display signals to be generated from all pixel data elements. The destination display time is longer than the source display time because digital display units do not require the long non-display times present in the display signals.
