Abstract: A new proposal for an industry standard code for video-tape editing and control is needed to replace the various codes now used, not one of which is compatible with another. The code must contain sufficient information to unambiguously locate any desired video frame within a reel of tape, and should be self-contained on a single audio track. The method used is a biphase space modulation employing 16 bits of control data in each code frame. These control bits can consist of a single 16-bit binary number, two American National Standard Code for Information Interchange (ANSCII) standard alphanumeric characters, four binary-coded decimal (BCD) numbers, or some other arbitrary code combination. Since each code frame is uniquely identified, the control information can be compound coded using successive frames. The effect of changing to a standardized code and the feasibility of code conversion equipment are discussed.
