A Unique Timing-Reference System for Broadcast Videotape Recorders
Bert H. Dann · Journal of the SMPTE · 1974
A system for deriving timing pulses for the servo and time-base correction circuits of a videotape recorder is described in which digital techniques are extensively employed for maximum stability. These techniques provide a coordinated array of timing pulses which can be manually adjusted to accommodate cable and system delays and, in conjunction with other special machine features, can be moved automatically to provide error-free electronic editing.
