ABSTRACT:
An analog signal digitizer for recording analog signals in a digital form on a video tape of a video cassette player. The digitizer is connectible between an audio production device, such as a compact disc, turntable, or any other audio devices of any quality, and a standard video recorder (VCR). Accordingly, the digitizer acts as an interface device, and converts the analog signals into digital form for recording on the wide band tapes utilized in these standard video recorders. The digitizer has a control circuit at the heart of its system, and it is provided with a memory device to produce control signals in association with audio information digital signals, and arranges these digital signals in a sensitized video-compatible format so that the video cassette treats the output signals of the digitizer as standard television signals.
