I hope I actually saw this post here, but I can't find it in the search....maybe someone recalls it. The discussion came around to syncing up projectors to external sources. Someone posted a a link to a DVD player that could accept a frame pulse from a projector and that would resolve to a DVD (or, I think, a CD)and keep them locked. For the life of me I can't recall anything else about it. Anyone else remember this, or was I dreaming? Any help would be appreciated.

This is probably the thread (and close to the post) you are thinking about:

Basic question about interlocking

I don't recal a DVD player that accepted any sort of timecode though. Maybe a DVD player designed for broadcast use... but I've never seen a non-tape adjustable / lockable rate player.

Now that I think of it, adjusting the frame rate on the fly with conventional DVD playback circuitry would be a real pain. Converting 24 to 30 fps frame rates would be no problem, but adjusting the processors clock frequency to affect the frame rate would likely crash (lock up) the processor.

You'd have better luck pulling a time code from the DVD player and adjusting the projector's speed on the fly. It'd certainly be easier. Oh yeah, cross your fingers that the DVD and film content match each other second for second.

I seem to recall there are DAT decks that accept external sync; so you can dub the DVD to DAT and go from there....

If I remember correctly Tascam's DA-60 will chase/generate SMPTE time code.

Yes, I've seen Tascam DAT players that generate/chase SMPTE. The DA-60 MKII can handle onboard or external SMPTE and has word clock in/out/through.

The Pioneer DVD-V7400 Industrial DVD-Video Player has an RS-232C connector for an outboard terminal controller, but I don't really know how those work other than some laserdisc players had them, too.

For some older prints it would be really nice to sync up 5.1 off a dvd insead of mono. Frank please post back here if you find a way.
