Description of nontime-buffered Improved-Gray-Scale PCM compression system, which was evaluated by scanning slides, digitizing resultant video signal to six-bit accuracy, processing digitized signal, converting it to analog form, and displaying it for photographic reproduction; evaluation of Coarse-Fine PCM system (nontime-buffered) indicates possible two-to-one saving with no degradation; systems using time buffering techniques offer bandwidth reductions of as much as four-to-one, and hybrid systems using nontime and time-buffered techniques offer compressions up to six-to-one with possibilities of approaching ten-to-one for average complexity pictures.
