Are you sure that’s how this works? Seeing things in color from the teens would be awesome!!! 🤣🤣🤣

can this shutter technology be use to colorize a black and white/monochrome crt projector? * (not black and white films) * I understand how film works!

The CRT scans at 180 frames and if the lccs screen part was put in front of another b/w CRT TV and the video signals into both TVs are the same source would result be a 20 fps color image? I want to try that on a vintage projection tv from 1951 i have.

It probably is digitizing the video; but at such a high resolution that the small monitor cannot resolve the individual pixels together and smoothly blends them together.

I noticed I had stopped listening and was drawn in to the 1980's video and it's….80's things. Okay, I went back and listened this time.

You shouldn't have recommended checking out Epcot. Clearly, that recommendation is why… all this… happened.

Being a professional monitor, it is designed to show all faults in the original video, including copy protection artifacts and "flag waving", which is what we used to call the switching / sync issues at the top of the screen from playing video tape without a Time Base Corrector (like your home VCR). So, while your consumer TV's job is to hide all faults and make the picture look good despite issues with your VCR or TV signal, professional monitors want to show every blemish so engineers can take steps to minimize it. A lesson I learned a while back when trying to use a professional monitor to watch time shifted TV.

I believe macro vision worked largely off of messing up the video timing and sync…a device called a time base corrector was used widely in tv stations back in the analog days…though digital magic did much of this in the digital world tv now works in largely.

A TBC matched the input signal to a reference signal and made the timing synchronized…thereby stopping the macro vision. We used to copy VHS movies in master control for our own personal use and macro vision never presented an issue. You could also alter the brightness, contrast, black level, hue, saturation and other signal components with a TBC.

I'd be curious if the back of this monitor has a reference signal input or how it would be affected with analog macro vision through a TBC.

The signal is almost certainly being buffered and read out digitally, it's just that it isn't using any sort of visually "lossy" compression like JPEG or MPEG, but rather something uncompressed like bitmap . A "bitmap" image or whatever lossless format this thing is digitizing each frame (excuuuse me, field) of video into is giving an exact value to each red, green and blue pixel, therefore is unnafected by randomness of stuff like snow that would wreak havoc on lossy compression schemes like MPEG.
We're talking about 1 field of standard definition here, so a couple megabytes of memory (if that) would be all that was needed, which would not at all have been a big deal in 2000.

I would suspect that this is one complex circuit. The real interesting question is whether the image brightness is controlled more by the CRT or the LCD display, and whether the CRT portion is all analog directly off the NTSC or RGB inputs, or whether it is running off the digital signal that drives the LCD using A/D and D/A converters to maintain sync. I would suspect the LCD is likely 720×480 or perhaps 640×480, or maybe 800×600 based on the age of the unit. First, you have to convert the signal to the LCD using analog to digital conversion, and to field sequential or perhaps the memory buffer allows multiple colors displayed simultaneously and changes the values for one color at a time. This likely adds a delay to the video. Then you have to drive the monochrome CRT, either field sequentially three times faster or by displaying the entire image at once, based on the grid pixel pattern of the LCD panel at a higher resolution. Somehow this circuit must derive how much light information goes to the CRT versus using the LCD light to dark of each color pixel. The real question if the CRT light intensity is also controlled to allow for more contrast than just what the LCD panel can provide. My varying the CRT light intensity behind the pixels you can send varying levels of light to the LCD panel filters, adding a major increase in the number of colors that the LCD can display without expanding the color depth of the panel. The sound will also have to be delayed to be in sync with the delay related to the complex signal processing of that unit.

it could breaks it out to RGB signals and then uses some sort lf a delay line to draw the fields. SECAM used a delay line as part of its approach.

There probly using an analog delay circuit. Lots of tv's use them to verieng degrees mid 90's on up to keep audio in sync
or for other video trickery PIP freezframe excetra.
i once had an analog tv or studio monitor cant remember that had a full 5 second delay from it's inputs.
this thing didn't even have an OSD all knobs and chunky pop buttons. kind of a channel selector for which input you were using. Never could turn off the delay and i went through every single button knob and gubbens on the thing.
Delay circuit was something to behold tho. took up a large portion of the internal space. huge jackpack on it tho. lots and lots of input. MMmmmm innnnpuuut.

This is a pretty cool piece of tech, but its disappointing that it only has composite input. Wonder how difficult it would be to mod for component.

Before 1990, a TV with a digital frame buffer would be ludicrous. After 1990, a TV without a digital frame buffer would be ludicrous. The sampling was probably being done at 4SC, so it is completely synchronous with the color. Demodulation then could be done entirely digitally. The frame buffer chips I saw in the late 80s operated at 4SC, 910 samples per horizontal line in NTSC.

Fun fact, when I was designing and building my CBS field sequential TV replica, I purchased a Tektronix TDS744A oscilloscope that uses exactly the same color shutter technology with a BW CRT. I was stunned by the coincidence.

I watch your videos with my five-year-old daughter and seven-year-old son. For their ages they have excellent attention spans, but your videos are wonderfully information dense. Your rant at the end sounds like a question either of my children would ask. I realize there are probably plenty of adults who asked about colorizing black and white films but on behalf of my children I want to say don't be mean.

I think that the the digital frame buffer is so good that, quantization noise apart, the reconstructed signal is identical to the analog one (Nyquist).

Of course it's digital, it has to be. In the analog electronic domain, you can delay signals, but you can't change the playback rate — but that's exactly what the device needs to do, with a 60 Hz signal coming and and playing it back at 180 Hz.
Also, there's no reason to believe that digitization artifacts must be visible in any way. If the sample rate and depth are high enough (say, DVD-spec 8-bit 720×480), the image will look no worse than, well, a DVD.
