I miss Radio Shack.
I actually used one of these long ago. The GPU I had on my computer had a S-Video out, and I ran a cable from that to my TV, but the TV did not have an S-Video input, only composite. As I recall it worked pretty decently.
Back in the day a lot of graphic cards with TV-out had only either S-Video or Composite, but not both. I learned that when I tried to find a fitting one for my small HTPC that I build. Since my TV had only Composite I made of course sure to get one with Composite. But if I’d had already one with S-Video such an adaptor would have been useful.
I have tons of those, my use case was a really old projector that only has s-video as it’s input.
I actually have one of these from around 2007! Back then I had a Lenovo laptop which had an S-Video output, and when I would travel to visit my grandparents in the summer I would want to play my ripped movies on the TV, which of course only had a composite input. So that was my use case for it where I actually had an output device with S-Video but no composite, and an input device with composite but no S-Video. Remember it working “fine” back then.
I built an S-Video to Composite cable some years ago to connect an S-Video out only videocard to a Composite input only TV. It was… functional. I got the instructions on the internet, IIRC it only used a ceramic capacitor (apart from the cable and plugs, of course) and picture quality could be somewhat adjusted by varying the value of said capacitor.
One other use I can think of for this is if one type of input is all full on the TV and you don’t want the hassle of an external switcher you could probably get this cheaper than a switcher and convert a device that normally needs the fully used input to the other where you have a free connection. It works better than I would have thought especially on that CRT, the reduced dot crawl could be worth the slight loss of sharpness
I remember those. I think internally they are just a capacitor and a resistor, something super simple like that, it’s been 20+ years since I saw the schematic on how to build one. I borrowed one from a friend to try in a room that had several A/V components and a projector, the hope was to get the composite VCR to S-Video so a simple A/V switcher could be used to select (other two sources being a DVD player and a Dish receiver,) but unfortunately, I got B/W video out of it, probably due to the very long signal cable to the projector (a distribution amplifier may have helped with that. We ended up just having to switch the projector to composite when VHS was used. I have seen a projector with only S-video and VGA, admittedly, such a layout is very unusual. Oh and agreed, it is a shame not having that store with the oddball adapters for most occasions, or the parts to build an even odder adapter.
Separating luma and chroma doesn’t require active components. The simple notch comb filter did it with passives from the 50s well into the 80s in consumer gear. The quality was lousy with dot crawl abound, but it works. The reason why the S-Video to composite video doesn’t really have dot crawl is the notch filter is very aggressive in that adapter. It basically stomped on the high frequencies (resolution) of the video to avoid it. Running a test pattern through it will reveal how bad it really is.
Whooboy I do not miss analog video. Good riddance. I worked with A-V & computer systems in schools and universities and when all the video became digital it was like we all had new vision. Component, composite, S-video, VGA, VHS, etc. never want to see that stuff again. However, another entertaining and historical video. 👍👍 Please do a video about your “new” Realistic LAB-89, another product from Radio Shack (and some undisclosed manufacturer). Have a great weekend in NJ.
I remember some laptops and graphics cards only offered ‘TV Out’ over S-Video, so these were especially useful for those situations..
I think I remember a video card that I had, it came with a short cable that was S-Video on one end (the one that went in the GPU), and a standard composite RCA on the other end.
I never got around to test that though.
Most of the TV in use when that adapter was sold, were old school analog CRTs.
A few of those clips in the demonstration video were shot one town over from me in Wantagh Park here on Long Island!!! Very random (but cool). The ironic thing is that for the last few years there has been a STRICT rule of NO PHOTOGRAPHY at the pool (after some creep was taking pictures of all the kids). 7:26 and 7:43 for example… Great video as always, VWestlife!!!
I have a Radio Shack A/V switch that has this converter circuit built in
Circa 2000 or so, I had one of these hooked up to my computer to use a CRT TV as a 2nd screen from a video card I had at the time.
I don’t know how many nights I fell asleep to the milkdrop plugin on winamp playing on the room TV with my fave playlist playing.
The card only had S for the 2nd video output, so one of these adapters was a life saver for me and the only reason I actually got dual screens working in 2000!
I’ve used one of those! My laptop only had S-Video output and my TV only had composite. It was a hand-me-down CRT but it did the trick!
Not bad for a cheap passive adapter.
BTW, I used to have a Canon EOS Rebel camera.
Why on Earth were ‘Are You Being Served?’ and ‘Keeping Up Appearances’ ever inflicted on US audiences? I feel sorry for you. Black Adder and Fawlty Towers I can agree with.
Back in the days before HDMI existed, some laptops or PC video cards used to have an S-Video output along with the standard VGA port, so adapters like this were very useful to connect those computers to a regular TV which only had a composite video input but not an S-Video one.
