Abstract
In order to guarantee phase-coherent splicing of pilot-frequency controlled tape in post-synchronization, a new device generates simultaneously both a pilot frequency of 50 Hz and an audible signal of 2,000 Hz in 50-Hz pulses, which is recorded on the tape during the leader part of the picture loop. This signal is created by projecting a vertical bar pattern of the picture leader onto scanning photodiodes. It is phase-coherent with the pilot frequency and serves as a signal for locating the splicing point.
