ABSTRACT:
A multiple video preview system for a production video switcher or digital effects device compresses a plurality of input video signals taken from various points along a video path through the switcher or effects device. The compressed input video signals are stored in a display memory in respective designated regions. The display memory is read out in a raster scan manner. The readout of a portion of the display memory occurs simultaneously with the storing of the compressed input video signals occurs in another portion of the display memory to provide a realtime video output signal that includes each input video signal in a compressed form. The video output signal is input to a monitor to display the input video signals simultaneously.
