ABSTRACT:
An audio/video system (100) is capable of introducing variable amounts of delay into a signal path so as to properly synchronize two signals, such a video signal and a corresponding audio signal. According to an exemplary embodiment, the audio/video system (100) includes first circuitry (50) for applying a first delay to a first digital signal. Second circuitry (80) applies a variable second delay to a second digital signal to time align the second digital signal relative to the first digital signal. The second circuitry (80) includes an addressable memory (84) for selectively storing the second digital signal and for outputting the second digital signal on a first-in, first-out basis to apply the variable second delay to the second digital signal.
