ABSTRACT:
A multiple television standards input selector and convertor selects a video signal from among a plurality of television standard format input sources including encoded video, analog component video and digital video. The selected video signal is converted to a predetermined standard format video signal for further processing by a digital video effects device. The selection of the video signal occurs within a vertical interval period so that no visible effect is detectable on a display when switching between video sources.
