These devices are SMPTE-to-MIDI convertors. While I don't know what
the pros in the studios would say about this, my personal thought is
that I wouldn't call them synchronizers, since there are machines that
sync one or more slave tape decks up to a master SMPTE source by
varying the speed of playback. (Although the JLCooper catalog I have
calls them synchronizers anyways ;)
I have a JLCooper PPS-100, which is a rack-mount version of the PPS-2.
Both devices take an audio input that is streaming SMPTE (Society of
Motion Picture and Televison Engineers [time code]) and converts that
to a MIDI output, which streams out MTC (Midi Time Code.)
Since I do film scoring, I'll tell you how you use this in a scoring
application.
If you have a master video (on a VHS or Beta or whatever tape,) you
stripe one channel of audio with SMPTE code. This gives every frame
of video a corresponding time in hours:minutes: seconds:frames
[e.g. 01:02:39:15] and is expressed by the audio coming from said
audio channel.
