Abstract : The merits of many analog matrixing techniques for color television, efficient video digital encoding techniques, color video pick-up devices, and color display devices were examined. Tradeoffs between picture quality and data rates are examined for both briefing and surveillance applications. The color systems investigated include NTSC, field sequential, two-color, equal band and SECAM. The efficient digital encoding systems investigated include delta modulation (single and multi-bit; linear and exponential), PCM pseudorandom noise, splitband delta modulation, dynamic delta, and block classification. It was found that digitally encoded NTSC systems are not necessarily best for military applications. A new system called LADECOLOR (Line Alternated Digitally Encoded Color) that includes some of the principles of the NTSC and SECAM systems plus the efficiency of delta modulation and data modems was found to be more effective. This new system will not become obsolete since it can incorporate advanced redundancy reduction techniques as they are developed. (Author)
