EXPLOITING TELEMETRY DATA IN THE VERTICAL BLANKING INTERVAL

Abstract

This paper describes how ongoing developments in digital and video technology have been merged to exploit the telemetry data inserted into the vertical blanking interval of the composite-video signal. The insertion of 96 bits of digital data into two lines of the vertical blanking interval is reviewed. The automatic retrieval and reformatting of the digital data for use by a Main-Frame Computer is explored. A unique video editing and data merging facility coupled to the computer is described. To emphasize the versatility of this systems approach, specific industrial applications will be outlined. Finally, future considerations and applications involving control systems will be discussed.
