Abstract
A new television frame synchronizer has been developed by employing the latest digital techniques to eliminate the problems associated with maintaining synchronization by the use of extremely stable rubidium timing standards, or with genlocking two or more sync generators. The synchronizer solves technical problems resulting from the handling of a nonsynchronous video signal from multiple remote sources and various studios, and it permits expanding program production techniques, as well as introducing savings in operating expenses. Eight-bit A/D and D/A converters are used with sufficient digital memory (approximately 3 megabits) and associated circuits. The resultant output signal is completely synchronized with the local reference sources in frequency and phase.
