TDM SCHEME FOR DIGITAL VIDEO PROCESSING

摘要

A TDM scheme has a Y signal that is sampled at 14.32 MHz and every other sample is discarded. The discarded samples are 180 DEG out-of-phase from line-to-line. I and Q signals are sampled at one half this frequency and every other sample is discarded also 180 DEG out-of-phase from line-to-line on a given line. The discarded samples of Q and I are 180 DEG out-of-phase with respect to each other. This allows insertion of the retained I and Q samples into the retained Y samples to allow multiplexing.
