Abstract
Abstract A video camera is adapted to provide an asynchronous computer-friendly output signal instead of a standard analog video format. The output signal becomes a digitally-encoded message wherein each video frame becomes a serialized string of digital data demarcated by a digitally-encoded initiator identifying the ensuing data as characterizing that entire frame. The beginning of the entire set of frames that comprise the total video message is identified by a special header comprising a time stamp code and a format code.
