So some words end in 0xA1 and I think this is an indicator of "this word goes next to a bad word". So it can take them out if they appear next to a censored word. so, like, "these", "those", "his", "a", "of", "my", "your", "the". not "her", apparently.

thank fuck that, uh, "sexual assault" isn't in the censor list, or I bet it'd also end up as kiss.

okay I have it basically decoding the file, I just don't know what all these values mean yet. There's a "trailer" on each word, which means... something. and there's "flag1" which I think maybe has to do with the censor level?

@dadiv
raised an interesting question: what would it do if your captions said "DICK VON FUCK"? I suspect it would allow it!

anyway I have 4 different models of these on the way from ebay and I'm gonna set up some crap to generate my own captions and watch what happens.

I'm annoyed that it puts anti-blocking on MAGNA CUM (LAUDE), but people who graduated SUMMA CUM LAUDE or simply CUM LAUDE are right out.

(I graduated "with distinction" which I think means my grades were shit but all the teachers for my major liked me)

anyway the first thing to do when I get one and can hack it is remove the negative match for "DICK VAN", or "JERK VAN GAY" as he's known.

Oh my God I just realized something. It overlays the censored text as an image in the video, right? You know what that means, right? THIS THING HAS A FONT!

I've acquired ~20 VHS tapes for 11.03$ Mostly R-rated 90s films, with a few kids movies thrown in for reverse-censorship experiments.

I almost bought Bad Boys twice because I didn't realize these were the same at first.

Left is Technology Connections' unit, right is mine. Looks like they switched some chips around, but it's fundamentally the same.

U3A is a PIC16C622A-20/S0. That's an 8-bit 20mhz chip, one-time-programmable, 2,000 words of ROM, 128 bytes of RAM.

U7 is a 74LV4066D, quad analog switch. I'm betting this is just plugged across the audio inputs, and is used to toggle them off when there's swearing going on.

U8 is a JRC NKM2207 Video Super Imposer. This chip overlays another signal (usually text) on top of an NTSC signal.

I need to get a DC adapter and some more cables before I can test this. but I had a silly idea: the EEPROM chip can be, in theory, reprogrammed by the PIC chip, right?

@Foone
they'd just need some special captioning start-phrase and then embed the new list into the tape as captions, then have the PIC detect it and reprogram the EEPROM based on that.

okay this looks terrible because it's only shown for a second and photographing CRTs is hard, but it's working! and I have version 1.06. GOOD. The one that's already been dumped is 1.05!

So I've also got the TV Guardian LT, and here's the interesting thing: it works COMPLETELY DIFFERENTLY. well, mostly completely differently.

So here's the thing: it has no OUT. It only has composite video in. No out, no audio, nothing.

@Foone
it still fundamentally works by looking for bleepable words in the closed captions on the composite video, but it can't add edited captions anymore, since it can't output any video. it also can't mute audio, since there's no audio pass-through... OR CAN IT?

It's infrared! it's got a sensor on the front, and it comes with an IR emitter on a long cable. You teach it your remote's "mute" signal.
