Various CRT TV Research for Tenna Purposes
please use this information to hurt him. or do other things to him. also send me links
I grew up with CRT TVs as a kid but like. I was a kid. I'm much more of a computer science person than a mechanics person but whatever
I'll also toss in some speculation on what each thing could mean for tenna here and there
Depending on how long the Dreemurs have had their TV, Tenna could probably be from anywhere between the mid 80s to the early 2000s.
I went to a manuals website and picked the Panasonic TC-14S3R at random. From what I can tell this particular TV is from the 80s, and I'm going to base a lot of the information here on that particular manual.
Contrast: Low contrast = more gray, less range in color and brightness. High contrast = more vibrant colors, lights are brighter and shadows are darker. Both increasing and decreasing contrast can cause detail to be lost. Lowering contrast can lose the subtle differences between similar mid-level shades and colors, whereas increasing it loses differences in bright and dark images. Could perhaps correlate with emotional state? Low contrast = low emotional range (maybe not necessarily depressed, but both happiness and sorrow etc. are muted? Could have a similar effect to taking an anti-depressant, perhaps), high contrast = high emotional range, highs are higher but lows are lower. Perhaps helpful for being exciting for TV but difficult to deal with emotionally.
Colour: The manual didn't specify what this does that I saw, but it's probably just the saturation setting. No saturation = black and white, high saturation = extra bright colors. Emotionally, I imagine low saturation would correlate with depression, whereas high saturation would correlate with joy (or even mania).
Brightness: Pretty straightforward. Darker image vs brighter image. If contrast and color were to stand in for emotional state, I imagine brightness would be more associated with energy levels. Perhaps his screen gets dimmer as he gets more tired.
Sharpness: Low sharpness = blurry image, high sharpness = things look clearer and harsher. Perhaps his image would become sharper as he focuses... and things like drugs and alcohol (or equivalents) could cause his image to blur.
Also related to image settings: The colored bars you often see are the SMPTE pattern. It's used for calibrating brightness and other color settings.
Here's a screenshot from a video I referenced that shows some other settings you might see on a CRT TV:
Some I didn't list already include:
Mode: From what I understand, just a bunch of presets for watching different sorts of things. Pictured is sports mode but there might also be a movie mode among others. Modern TVs still generally have this
Apparently "Picture" here is just contrast.
"Hue" as far as I can tell lets you shift, well, the hue. It's not normally something you need to mess with. If your reds are red and your blues are blue, etc. You're probably fine. If we assume that colors have some association with Tenna's emotions, though, I imagine that messing with his hue settings could really screw him up. Make him happy when he should be sad, something like that.
And then there would also be things like volume (I feel like turning down his volume has a lot of potential), input (normally he'd get input through his RF Input, as discussed in the next section, but I feel like switching him over to a different port would again, have potential.
Alrighty, the spicy stuff.
So there's a few different ways to get an image and such onto your CRT tv.
Usually with a modern TV you'll just have HDMI and that's it. One cable and you're done. Maybe your tv will even be fancier than that and have a USBC port. I feel like QUEEN is probably a bit too old for USBC, but she probably does have HDMI. But I'm getting off track.
RF Input: Stands for Radio Frequency input. Handled both video and audio with one cable. As far as I can tell it became common in the 70s? Was often used for cable TV or "over-the-air" broadcasts from TV stations. The cables are also called Coaxial Cables. They have a prong in the middle, and are attached by screwing them on. Apparently RF is also prone to interference. Things like wifi, bluetooth, and microwaves can all cause RF interference, apparently. And also electric fences. So basically put a shock collar on that guy and see what happens
This is what Tenna's antennas would be connected to. I imagine disconnecting him from this would be... disconcerting, at the very least. He'd probably go blind and deaf or something.
Composite: The red white and yellow cables. Very common, you've probably seen them before. The yellow cable handles video, while the white and red cables handle the left and right audio specifically. Having one cable unplugged doesn't stop the others from working: you could have just the right audio but nothing else, or just video but no audio, for example. Again, implications. possibilities. This is what my Nintendo Wii uses. Usually provides a clearer signal than an RF connection but not considered great.
S-video: A cable for video transmission that's better than composite, apparently. Doesn't do audio though, so the audio data needs to be plugged in separately.
Component: Needed for high-definition television. Three cables for Luminance, Blue difference, and Red difference. Doesn't seem to handle audio by default?? And apparently there can be up to 5 of these cables??? They were quickly wiped out by HDMI cables though. Considering Tenna's age it seems unlikely he would have had ports for these.
The power cable on a CRT tv would usually be permanently attached.
Right so this is where I start to struggle to understand things, but I'll do my best. If I get anything wrong here please let me know or reblog with a correction.
The front of a CRT screen has a coating that glows when it is hit by electrons. The screen does not technically have pixels, but does have an array of different colors of phosphor (the coating). To create different colors, different dots are hit. As far as I can tell this functions very similarly to pixels or how images are printed in magazines.
Anyway, at the back of the TV there is basically a laser (not the right word I don't think because it's not beams of light it's beams of electrons but whatever) that is shot at the different areas of the screen to create an image.
Anyway it's all rather complicated if you want to learn more read the wikipedia page or watch one of the videos I linked. Here's the stuff I care about:
CRT screens are very delicate and you basically can't repair them, because they are vacuums. When you smash a CRT tv you can kind of see them implode in a cloud of dust. You can't really come back from that. From what I can tell the only way to repair a CRT tv with a shattered screen is to replace the screen entirely, which seems to be by far the most important, complicated, expensive part. If the screen shatters you can salvage some components but ultimately the screen will need to be rebuilt or replaced entirely. Also, they don't make CRTs anymore because they are so complicated and the market isn't there. What I'm saying is Tenna is extremely lucky the Knight didn't break his screen, and if Tenna's screen ever did break that man is screwed. And not in the fun way. Unless you are me.
I added too many images so I'll reblog this again with the rest of the info I find
