D2 Digital Composite to SDI

[Andrew Rendell]

I used to use a Vistek “Varicomb” decoder for that. It’s been a while since I’ve seen one though (so long that I seem to remember that the box gave us analogue YUV and making that SDI was another step, or we would go straight into a Degibeta deck’s analogue component inputs). Google “comb filter decoder” and you might strike lucky.

This is on ebay right now, I have no connection to the seller,

or this cheaper alternative, just have to figure out the missing power supply issue.

I bought a set of Accom D-Bridges [a 122& a 221] to do the same thing, I never did test them, HDV kinda happened, making SD gear not so attractive.

Innovision built a box also that did D2 to D1 conversion.
