1. A digital recording and replay apparatus comprising:
means for processing a compressed digital video representative digital signal stored on a recording medium to produce a compressed digital video signal bit stream;
means for generating a mode status data tag signal indicative of an operating mode of the digital recording and replay apparatus; and
output means for outputting the compressed digital video signal bit stream and the mode status data tag signal, wherein a receiver receives the compressed digital video signal bit stream and the mode status data tag signal, decodes the compressed video signal bit stream to produce a decoded video signal, interprets the mode status data tag signal to select a stored signal representing the operating mode indicated in the mode status data tag signal, and combines the decoded video signal and the selected stored signal.
