High Definition Stripping, Genlock, and Timing Regeneration for Multiple Formats of High Definition Video & Film

For High Definition Video & Film outputs, both symmetric (1-to-1), and asymmetric combinations of sources and timings are used for output genlock. This paper describes techniques being used in a system to lock both types of combinations. To simplify the numerical complexity of these timing relationships, a new mathematical notation (recently invented for describing digital audio timing relationships), called the “Log Prime” vector is introduced. This paper considers timing stability challenges for High Definition interfacing, and presents the genlock architecture of a High Definition I/O board now being used in multiprocessor computer servers and graphics supercomputers.
