Abstract
Abstract A television signal encoder/decoder control provides for quick and easy modification of circuit parameters for a television encoder/decoder. A microprocessor interfaces with both local and remote interfaces for obtaining parameter data, sets up the encoder/decoder according to the parameter data, and then stores the resulting setup parameters as a preset. The preset may then be instantaneously recalled and the encoder/decoder set up in the stored configuration in the space of a video signal vertical interval.
