Abstract
A digital apparatus for reproducing a digital video representative signal stored on a recorded medium is connected to a receiving device including a decoder. The apparatus comprises a processing means for the digital video representative signal stored on the recorded medium to produce an output compressed digital video signal bit stream for decoding by the decoder. A status message generator generates a message data signal indicative of an operating mode of the apparatus. A display message combiner has a first input coupled to the message data signal and a second input coupled to receive a decoded digital video signal from the decoder, for combining the message data signal with the decoded digital video signal for display on a video monitor.
