Abstract

An audio timing generator includes a programmable means, and a number of signal logics and counter logics. It provides timing information for audio data processing in a VTR recording channel. The present invention provides an audio timing generator adaptable to various industry standards including but not limited to 625/50 and 525/59.94 video tape recording systems. Further, it is adaptable to provide timing information correction within a field when audio timing delays in the recording channel had changed.
