A new technology in bar code scanning and digitizing is provided where a bar code within a composite video signal may be detected and decoded. In a preferred embodiment, the composite video signal is converted into a form suitable for providing to a bar code decoder, in order that any bar code within the video signal may be decoded by the decoder. The output of the bar code decoder may thereafter be provided to, for example, a computer for the further processing. For purposes of the present invention, the composite video signal which is decoded may be generated by a video camera, a video tape recorder, a television signal, or any other source which generates such a video signal. A sampling of the multitude of possible applications of the present invention is also provided, whereby bar codes detected by, for example, video cameras in different environments may be decoded and processed by a computer.
