摘要: A pix-in-pix television signal processing system develops a composite video representing reduced-size auxiliary image insert in full-sized main image. The is separated into luminance and chrominance components by filtering circuitry. subsampled ratio of one to four the signal, which composed two color difference signals modulating quadrature phase related subcarrier signals, applied circuitry interpolates between selected pairs samples develop frequency converted having frequencies that are one-quarter original signal. combined generate This with
