Australia's largest supermarket chain is currently in the process of replacing all normal barcodes with data matrix codes on the packaging. This lets them store a whole bunch of things like the expiry date, batch number, etc. So if you try to scan something that's expired at the checkout it won't let you buy it

Actually there is one 2d code missing, a code most of us had heard from (but maybe not about): Dolby Digital Code. This was one of the digital sound recording methods on analog films, between the perforation, was scanned by a little camera, decoded and given to the amplifier. About 15 years ago this code went pacticly away with digital projection coming up - but till then it was one of the most used 2d codes (4 codes per picture, 24 pictures a second), so anyone watching a DD movie in cinema heard 345600 2d-codes per hour (of course there was much redundancy in encoding, as parts of the perforation might get damaged).

I found out something sort of recently that was interesting. 1d traditional barcodes are actually read with the white spaces between the black lines. In hindsight that makes a lot of sense because it's the reflective part.

8:52 actually for RS-Code you always need 1 EC block to verify that the data is valid and then 1 additional block for each corrupted block in the data segment. so to replace 1 corrupted/missing data block you need 2 EC blocks. To replace 3 corrupted/missing data blocks you need 4 EC blocks and so on.

@Crazytesseract

3 ай бұрын

To replace 3 corrupted blocks you require at least 6 additional EC parity blocks. If you have N redundant EC parity blocks, you can correct N/2 symbol errors (block errors) at the most. Assume N is even.

LOL But honestly, there have been insane discoveries made by people in a non-rational state of mind. Maybe you're onto something. /s

This is a fascinating subject matter. Aztec codes, I have read somewhere, are better for use in mobile device displays than QR Codes. I would guess that their appearance makes them somewhat faster and more resilient for that purpose. Also, since they spread from the central pattern, I would also guess that they make it possible to emphasize certain parts of the encoded information (that closer to the core) and make partial readings possible.

Excellent show, Joe! As someone who was involved in building and programming barcode readers years ago, I understood most of what you were illustrating. It is fascinating how the relatively simple, one-dimensional designs have developed and expanded, using most of the same original principles and concepts.

The "Mask" that flips the blocks in the QR code is a process that is also used in digital signal transmission, called "Alternate Mark Inversion" so instead of having a digital signal that has a long string of 1's or 0's, these are broken up. This also helps with basic error detection in digital signals. If part of the transmission system receives no signal input, it creates an alarm signal to signify loss of signal at that point, and then injects a string of all 1's to transmit forward. This is an "Alarm Inhibit Signal", so the system recognises the point where the signal is broken, but prevents parts of the system further up the chain from creating their own alarm signal. This means the first place where the signal failed can be identified. Further up the system the all 1's signal registers as a "valid" signal, but displays a warning there is an all 1's input being received, so you can tell that there is a problem somewhere back from that point.

9 years ago(I am 14 now), I used to think that a computer, like a billing machine would search for words hidden in those patterns. And I used go spend a hell Lotta time actually finding any letters or words hidden in the pattern of the qr and bar code 😅😅

Awesome video, I never gave these much thought other than presuming they were magical. After your explanation I at least know they were produced by some very smart people. Thanks for the tutorial, you make it easier to understand.

Superb information. Never knew it was that complicated. Fascinating.

Funnily enough, some airlines also use Aztec codes for their mobile/digital boarding cards, as well as the PDF417 on the paper/printed ones. In my experience they're easier to scan off screens (and faster to process), probably because they're smaller and less complex. However they have less data in them, so occasionally you have to get a PDF417 reprint when certain things happen

Wow, you are still my go to guy for cutting edge information made more simpler.

I met CIRC error correction method at first in early seventies for Compact Discs. For every 16 bits of data there were 18 bits of error correction. I tested it putting a radial black tape on a disc and it was read correctly. Amazing.

Barcodes have always fascinated me. When QR, 2d and 3d barcode started showing up, it just amazed me, even though I understood what was going on. What amazes me more than anything is that we have printers with enough DPI control (I mean you can print all these barcodes on a bubblejet).

The developers when Joe says "Yeah it's complicated but the computer has no problem understanding it": 🥺

Haha. The original developers :) We just need to use well written and tested libraries now 🧐

If it got original qr code image and not photo from a camera

This guy is trying to be regular, I am really into this information.

Your videos are always very worthful. Thank you bro

3:51 “ah yes hello good day this is a very good thing of text that will still be readable despite covering up lots of the actual code”

it's strangely adorable how he's constantly reassuring us thay the computer knows what it's doing lol

This video deserves more likes and views, I could imagine the amount of research done to make such a video

Man that research certainly took so long. Thanks for explaining in an easy way!

Proud to be in first 150 viewers 😎

i was send to this video by a QR code 😂

Plot twist: You're a qrcode

I learned some things from this video, thank you! I was disappointed in the discussion of error correction, though. Because the rest of the video is so high quality, the error correction hand waving really stands out.

Selection of topics for videos are lit

When I started watching the video: hey I could make a program in Python to make these, it would be fun 5 minutes in: I guess I'll just make one to decode them, it's already good enough 10 minutes: why

The setup seems to have changed, especially the colour scheme. Not gonna lie, it looks cooler.

The camera seems higher

Holy crap! I have always wondered how these all worked, I knew they were information of some sort but how they worked with a camera just amazed me. Now I _kinda_ get it, a bit. ....Just a bit!! You explained all this so bloody well!! Thank-you... Love how people scanned the examples and you left Easter eggs everywhere for them to find! I am sure this has been answered in the past and no doubt you get asked this frequently so are sick of explaining it, but what is that tick you have with your left shoulder/neck?

Thanks, this was really cool (I’ve always wondered how these codes work)!

who else noticed a package from Bruce to Kent in 2:11

1:57 I scanned the code and it said: STOP SCANNING THE EXAMPLES

Thank you for empowering me with the codes

Thanks - never new any of this info - really informative.

2:02 : oi mate i swear on me grave if you dun stop scannin these examples i'll give you a proper slap

Can the coloured 2D barcodes be considered "3D" since the colours represent the barcodes's "depth"?

I love how your examples got angrier and angrier with me for scanning them

🤯 great video have always wondered about the other codes

Dude I just read the Wikipedia page on QR codes don't question my knowledge

0:40 i searched for rick roll QR code and i found the same qr code

Love that you put easter eggs in there!

The video is really informative. Thanks a lot!!!!

For anyone wondering - the first one on thumbnail says: “This is QR code”

9:40 I wonder with this knowledge if it's possible to generate a QR code that has a fake finder pattern.

I think when there's something weird the qr code making software changes the mask

0:29 used Scandit on the codes here and wow the aztec barcodes were obnoxiously fast. I can see why it's used for tickets. Pressing back after scanning just rescanned it immediately before I could move to the next code. Also it was not able to read the bottom left one (PDF417 one) likely due to resolution (even on fullscreen at 1080p) and was struggling to scan the two stacked data matrix barcodes. Took a bit of fiddling to get a scan with them. Very fun video!

3:31 Best one ever and totally didn't see it coming. Should have included the URL too.

3:30 specially

as far as scanner apps go, I've always used one just called barcode scanner and it works fine with 1d and 2d codes, it's actually helpful to get some longer 1d codes if you need to scan one.

Wow. You did a great job explaining something technical in a non technical way.

This video answers EXACTLY what I was wondering last night and I talked about it with a friend. About the QR code with logos covering the center and concealing some data. Thanks youtube algorithm, I guess..
