摘要：
Apparatus for combining an auxiliary image and a main image includes a source of a main image signal and a source of samples representing an auxiliary image signal. A subsampler selectively subsamples the auxiliary image samples in either a quincunx subsampling pattern or a rectangular subsampling pattern. A signal combiner combines the main image signal and a signal representing the subsampled auxiliary image samples to generate a combined image signal. A control circuit generates a freeze control signal for the subsampler which conditions it to take samples in the rectangular subsampling pattern during a freeze frame operation, and in the quincunx sampling pattern otherwise.
