Technology Connections - did you get chance to read any of the twitter threads by foone yet? They did a full disassembly of the TV Guardian code. ;) EDIT: I may have been wrong about the full "disassembly", but I haven't looked at it in-depth again for a while. They also just bought one of the newer devices two weeks ago, and dumped the ROM from that. A very interesting device, and also hilarious.

In Technology Connection's video (at time 7:07), you can see that the Guardian removes articles attached to the foul word (in that cases it censores "What the fuck is that?" into "What is that?"). The whitelisted words are all articles (the, that, those) that would have to be removed to maintain the sense of the phrase. Probably for the microcontroller firmware, the fact that the word is whitelisted and has a substition bit (0x1) flags it as "if encountered before a foul work, also remove that article"

I had trouble explaining to my wife just now why I was laughing so hard... "No, because when they were testing it, it would have turned Dick Van Dyke's name into Jerk Van Gay and they would have seen that and said a bunch of things they'd need to censor." It's the kind of ridiculous secondary problem you only truly appreciate as an engineer, and it rises above foul language.

Watched the original video on how it works. I think for “the”, if it is before a “naughty word”, it will eliminate it. So “what the f” just becomes “what”. But if no naughty word follows, then “the” is allowed. Possibly the 01 and 02 could indicate searching for a naughty word after or before the regular word. Hence “F you” would return blank, instead of “you”. Now, with that said, if you enable write on the chip, you could create a reverse device that takes pg rated dialogue and spices it up a bit! What does the other chip do?

@@MadScientist267 I beg to differ Mr. Mad S. there definitely are ways to learn something in school that you can use in real life! Oh, I'm in Europe, maybe there's no point... but seriously, back then, I was a teen in the 80s, in high school (I guess, we call it middle school, age 14-18) i was studying to be an electronics technician. Didn't make much of it, after all it was in a slightly underdeveloped country where the proliferation of tech progress was sort of tied to political affiliations so the teachers were not super motivated to invest into really getting us up to spot. But, there were ways to get past that, for example if i only knew how important the proper instruments were, including soldering stations with all the gadgets, we could have organized so every one in class gets what we can and organize sharing equipment that was too expensive to get individually. And go on with sourcing chips and other stuff that goes on a pcb from throwaway stuff. Even in Yugoslavia it was not impossible to get microprocessors from the 70s, if I only knew how important that was, alas I saw most of it as a chore to chew through, ofc lamenting that we had to study so much other stuff, like history and biology and whatnot. I was envious of the american school system, at least what we saw in movies, they seem much more project oriented as opposed to pronounced "ex cathedra" teaching that I experienced, but there were ways to hack oneself to proper education. I think even today it helps if a kid that's bright but not too fond of school (like my 11yo) focuses on the 2-4 teachers and their subjects that they like and treats the others like assistants. And there you have real life, figuring out how to talk to teachers is much like later talking to colleagues and superiors.

@@florkgagga Schools teach principles. Not real world. I'm sorry but it's just how it is. I'm not negating their place in the mix... But attempts to blow smoke up my ass aren't going to work, when I've seen time after time after time where it failed to meet expectations in the real world. As an old boss put it more than once, "take the paperwork into the bathroom, it'll serve better there". His point was you can't teach critical thinking, and all the school in the world can't make up the difference. People either got it or they don't, and the information alone is useless. Without the critical thinking, watching someone try to apply the knowledge would be much funnier if it wasn't so sad. People pigeon hole themselves into positions they can't handle all the time... I've seen enough of it that I don't even care to work anymore until the educational systems are reformed. Passionate usually wins over educated in my experience. The difference is in what the drive is for... One is seeking to expand their universe and make a difference in ours in the process, the other just saw the numbers and wanted the check.

@@voidex136 I’d have to go back through the whole video again, but I think the device has the ability to silence the audio when it detects a “bad word” I’m suspicious of this because I don’t think the audio and closed captioning would be perfectly synced as to bleep words right when they’re happening…. It would instead have to block a whole section of rendered CC, or take really difficult to calculate guess as to when that particular word was said. I don’t think CC is encoded with enough granularity to pull it off… I’m sure a few things i said here are incorrect so i hope someone can give you a better answer.

At a glance, I would say the 0x2 is telling it to look at the prior word, to sensor both. Which is why 'Balls' has a 0x2, to sensor, say, 'Hairy Balls' or whatever. However 'Tennis B' is explicitly whitelisted as an exemption. 0x01 probably does the same but for the word after, so 'Dick' would block 'Dick Head', which explains the exemption for 'Dick van'.
@EebstertheGreat
@EebstertheGreat Жыл бұрын
You would need to whitelist those anyway, because "tennis balls" would match the filtered word "balls," muting the audio and turning it into "tennis tail." Same with "jerk van." 01 only marks "dick" and "woody," which are also names. I wonder if there is a connection there. For instance, it might check if the word is capitalized, in which case it's probably a name. I can't see a connection for 02 words. I don't think it censors words that come before them. In your example, "hairy tail" is totally acceptable, and it wouldn't make sense for "Now you're pissing me off" to be replaced by "Now teeing me off," for instance.

@@brandonjob2202 *late 90s The original version of the TVGuardian was first released in 1998 and was most likely sold well into the early 00s. In the early 1990s, the PIC microcontroller line had only just released (in 1993 to be exact) Most of the datasheets for the PIC16C622A microcontroller in this specific unit have dates ranging from 1995 to 1998. The manufacture date on the PIC in this unit is between February 7 and 13 of 2000. And the EEPROM, despite being covered with some sort of blue paint, I can make out the manufacture of the EEPROM was between November 29 to December 5, 1999. So, this unit was definitely made in January or February 2000. Don't judge me, I just like correcting people. Bonus: my dad used to have this cable TV hacking device in the late 90s/early 00s generically called the "Quick Board" and used a very similar PIC microcontroller (the PIC16C56-RC/P), which has a manufacture date of August 14 - 20, 1995 (33rd week of 1995). If I still had some of the original cable equipment, I would have been able to test the circuit board based on a chip that's a few days older than Windows 95. Because I can't find anything on Google, I am going to assume that the Quick Board was in limited production (

(This is all from the perspective of someone who has spent decades watching, listening, and reading about other people doing interesting things, but never learning them myself. I feel worried that anyone with expertise is rolling their eyes at this effusive praise, but this video just clicked for me in a way that made me feel like there is a path that I can still follow to get there too. Sorry for dumping my insecurities out. Unfortunate habit of mine. But the venting helps. Writing long, rambly, meandering KZbin comments is mostly harmless and feels like free therapy sometimes.)

I'm sure this is just an iterated list down the line until it gets a hit, or falls out of the bottom and just gets passed on. CC isn't high bandwidth, I mean the scheme is done in just a few video lines, and tracking spoken paces, this thing is *still* spending most of its time in a sleep. Just scans that address range upon receiving each word, comparing them whole. That's how I'd do it, not much code, and raw speed isn't necessary. One hint this may be the case is the "dick van" case... It has "dick" stored twice there for one, but also would need another bit to do things like exceptions/qualifiers... Either cutting the sub list further or sacrificing another function. Watching it in situ would prove it out of course, but while I'm not privy to the finer details of CC, I'm sure if they used fancier tricks, they'd also be capitalizing on the protocol of the original CC... So that would be a place to look for other clues as to their thought process.

With the limited space in the PIC I would guess that that is a simple block table that provides an index into the 256 byte blocks found in the EPROM. So words starting A-C would index to block 0 and so on. As they seem to be on rev 5 of the firmware it would explain why one of the word blocks on the EPROM is full - they have added words and features without completely re-indexing the blocks.

@Isaac Alonso. The PIC microcontroller does not have enough program memory to have a lookup address for each bad word. I think they broke up the words into groups within 256 byte blocks (why we see a lot of NULLs or 00's at the end of each block), then took the first two letters of each word to start a rough search in a specific block in the EEPROM library and then complete the search after finding a 2 character match. This way 'ASS' and, say, 'SHIT' could each be looked up quite quickly, 'AS' starts the search in the first 256 byte bank, and 'SH' starts the search in its appropriate bank (several blocks deeper in EEPROM), thereby skipping the blocks it knows it won't find it. My ZX-81 computer did something similar for variables, I can call a variable pretty much anything that I wanted, but only the first two characters are used to look up the variable: 'APPLE' , and 'APE' would not be allowed in that case. The PIC is using the same first two character to select a bank and look for matches based on the flag bytes that follow the dictionary words.

Somebody probably already mentioned this, but "foone" on Twitter (and others) did a full disassembly of the ROM from the original TV Guardian. I believe foone also bought one of the newer devices only two weeks ago, and dumped the ROM from that as well. Their twitter threads always make for an interesting read. Lots of nerdy tech details.

Weirdly I learned more about spreadsheets in this video than in my entire life (of avoiding them) up till now! I tend to just write software to perform the calculations on CSVs :) In this case I probably would have performed the data processing in code and added it to serial output but it was interesting to see how the spreadsheet does it!

@@lasskinn474 Fun fact, at a previous job where I was mainly an admin over a UNIX/Oracle DB farm I converted some hellish Excel spreadsheets that had grown over years in the accounts team, into a complete mess of tables and single-file databases, to a web interface pulling from Oracle. The spreadsheet would take literally 10 minutes to update, and the DB would do it almost instantly. It was even faster when I added a bunch of MySQL slave servers to Oracle (using triggers in the Oracle DB to push updates, inserts and deletes to MySQL and optimised them for the type of queries they received. I don't know anything about spreadsheets, but clearly they have limits to what's sensible with them.

Very good job on this one Ben. After high school, back in 1974 I went to DeVry tech for basic electronics. This was before MCU`s and MPU`s. So I really did not get a deep understanding of digital stuff. But I managed to work in electronics the rest of my life. Mostly as a test technician at the factory level in circuit board assembly plants. Most of these places make circuit boards for many different customers, so I do get to see and test a wide variety of circuit boards. You are the kind of brain I need when I have boards that fail test and i`m just lost. LOL.

This was a godsend. I personally hold an AAS in electrical engineering technology from my local community college, so I could follow along with the material presented (part sheets, desoldering, the Arduino code, and so on). I thought it was great that the material was presented in such a careful, formal manner that it was on par with (if not exceedingly with) the higher education classes for my Associate's degree. And after the initial presentation, which was on par with college education, the end result was just a list of bad words. I don't know if it was genuine poetic irony or just my own personal immaturity, but that contrast was the best thing that I've ever seen in an electronics video. I loved it.
