Versatile Transmission Video Facilities at NBC New York
The operation of a television network requires the efficient and reliable processing of a great number of video signals not only from in-plant studios but also from diverse external sources via satellites, network land lines, and microwave systems. The new NBC Transmission Center provides direct monitoring access to 120 video inputs and 6 independent output channels (expandable to 10). It provides 26 video processing amplifiers and includes 30 source selectors for any of 100 inputs to 30 user entities; there is also a character generator “menu” display for supplying updated information on resource reassignment and emergency change. The use of patch cords has been greatly reduced compared to past practice.
