The advent of video digitization advanced and simultaneously threatened the broadcast business in 1973 with the introduction of a digital time base corrector and in 1974 with the full-frame synchronizer. Limited digital techniques such as character generators had been with the industry prior to this but were not in themselves manipulative of the video signal. The actual a-to-d, memory, d-to-a concept of timing a video signal has been with us just six short years in which time we've witnessed more progress in application than in practically any broadcast equipment area in the previous six decades. Both consumer and scientific demands on memory mediums have advanced us through 1K to 4K to 16K chips with a promise around the corner for 64K and 128K single chip capacities. The broadcaster has found himself in the position of either grasping quickly the concepts of digital or hiring young, bright engineers with an emphasis in that domain.
