Composite Cable to VGA

Everyone I know has old stuff and they ask me questions like I know the answers.

Here's the setup..

X-ray machine (coaxial) -> VCR (for recording) -> Composite cable to a possible 1980s Soviet Union era TV.

The TV is dying. Is it possible to get a converter to throw a computer flat panel there?

Thanks

There are several composite to VGA converters -- so it shouldn't be too difficult to find one that works.

Why not just get a flat panel TV that has a CV input?

Space.

If you can find a 15 or 17" TV instead of wall-mounting a flat panel (he is remodelling) that is about as thin then it'll work.

Composite to VGA won't work with a passive adapter. You do need electronics to separate at the very least sync and luminance (for a monochrome picture). If you want to preserve colors it gets even more complicated (chroma -> RGB).

I would use a PC monitor that has a composite video input (I have several that do and they aren't all that expensive) to avoid the need for a converter but if you enter "composite video to vga" into a google search you find a number of them ($30-100 range).

If it hooks up to a Soviet TV there's a probability that it's PAL instead of NTSC. You may not find an adapter on this continent.

I thought most of the Eastern block countries were actually SECAM, but I don't think that should matter with CV.

It may indeed be SECAM or PAL, but either way you're going to have to deal with crazy scan rates and horizontal lines.

I don't understand how a Soviet made monitor can function at all on 120 VAC @ 60Hz.

You are correct about SECAM for the former Soviet Union, but are wrong about that the encoding standard not mattering for composite video. The encoding standard determines the sync rate, number of total and visible lines, offset for chroma carrier and how color information is included in the signal.

I thought most of those encoding was in the TV signal, and once down to CV they wouldn't matter, but I could very well be wrong -- haven't looked at them in 20+ years.

Many old Soviet-era TVs had voltage selectors for 127V IIRC.
Side-note: most of (Eastern) Europe is PAL. I can swear that the Russian station I could receive was PAL.
Many monitors that have composite input will do both PAL and NTSC just fine. I have an older Dell (7-8 yrs old) and it handles both.

Not the entire former USSR, just parts of it.

Not entirely. Well in a way. There are variations for PAL and SECAM, ex PAL-M is 525 lines 60 half-frames vs 625/50 for "regular" PAL.

There is a difference between "were" and "are".

quote:
SECAM was later adopted by former French and Belgian colonies, Greece, the Soviet Union and Eastern bloc countries (except for Romania and Albania), and Middle Eastern countries. However, with the fall of communism, and following a period when multi-standard TV sets became a commodity, many Eastern European countries decided to switch to PAL.
In many European countries with mixed coverage, especially in later years, TVs had decoders for both PAL and SECAM. And back then, the Soviet Union was a single entity in this respect.

Now that I actually saw the damn thing... it's a "US" TV from the 1980s. He was technically correct, it was around when the Soviets existed....

Uh anyhow. What's the equipment (amazon links would be nice) of stuff I would to get him going?

Composite to VGA converter .

LCD Monitor with composite input (just one example of many like it).

How about retiring both VCR and TV with one of those flat panel "all-in-one" PCs? Use a good quality USB dongle which handle all variations of NTSC/PAL/SECAM and the PC hard disk to store zillions of X-Ray charts.

I mentioned something like that but he didn't seem too interested.
