Abstract:
1. An apparatus for automatically checking cataloging and reporting errors in an AC-3 bit stream signal carried as a sequence of AC-3 data packets that repeat at a fixed spacing on a real-time AES-3 signal stored with a video signal and a time code for each frame of video on a recording media, said video and AES-3 signal providing a synchronized audio/video signal, comprising: an audio sound card that converts the AES-3 signal to computer readable language and stores the data in a computer memory; a time code reader that reads the time code for each frame of the video signal from the recording media, and a processor operative while preparing the recording media for broadcast, said processor processing the AC-3 data packets from the data in the computer memory to detect discontinuities in the AC-3 data packets from the fixed spacing as timing errors, reading the time code from the time code reader to assign a time stamp to the timing error and recording the timing error and time stamp in a log.
