'Or S-h-i-t" My sides ow
I love how he just casually shit on HDCP lol. I hate HDCP. It has literally prevented me from capturing my own content or fcked up presentations because some stupid computer or device couldn't "validate" or dock or whatever with some projector. What is ironic is that, a lot of stuff that should have HDCP like Netflix or Amazon prime TV on the Xbox doesn't and my capture card sees and captures it just fine but certain games will freak out my capture card every now and then. And years of backing up my DVD's and Blu-rays has just shown me how crappy DRM is.

Yup , exactly what it is ...
Agreed. it's just another arm of the DMCA, from the sounds of it: another political move to fight technology rather than embrace it.

Its also terrible at stopping piracy
No shit
its DRM
I say it does the opposite of stopping piracy. When being a Pirate is easier than being a customer guess what the average Joe is going to do.
If they want to "stop" piracy they can't compete on price so they should improve service, not actively be a disservice.
It encourages piracy. No more no less. When you see paying customers being treated worse than pirates, guess what you wanna be? Fuck Netflix and fuck DRM.
Step 1: Buy tv/movie from streaming site
Step 2: Get told i'm not allowed to watch in HD because something in my setup doesn't support DRM-horseshit
Step 3: Yarr Harr the 4k version and remember why i don't try to support my favorite shows..

One of the most common issues I run into in my work (ISP 2nd line helldesk) is customer TVs being incompatible with HDCP. Those are fun conversations where you have to tell a customer his TV is just too old.
You gotta love how many schemes that content providers come up with to try and prevent, yet further justify piracy.
they got ways to bypass hdcp so there schemes arent even working lol
@@AsianFlex why even bother to waste money on protection development?

I'd take 30 cables over hdcp bs.
I found it hilarious when boxes started appearing that "downgrade" the latest HDCP to an older one, "to help with compatibility" said the manufacturer. They're very useful😉
1:00 Linus that's not how you spell HDCP XD

***** Nothing goes over my head, not even the clouds.
Scrambled Highspeed Inconvenience Technology?
Yeah... My cable box even prevented me from recording a rented movie to my dvd recorder, saying "Cant record copy protected content" when i pressed the record button on the dvd, connected via SCART, the older, fatter and analog brother of HDMI. But that was easy to bypass. 2 adapters and 6 wire cable, and i was able to record it.
Surprised that Macrovision did not trip you up. Edit: Maybe that is an NTSC-only thing.
I think it's cute that the media companies who created HDCP seems to think that people pirate their content by making a real-time recording of the original video with something like a VHS recorder like it's still the early 90s. Instead of just, y'know, ripping the digital file directly from the source.
Great video Linus! Thanks for the info and easy to understand explanations. Love the abbreviation for HDCP. ;)
HDCP sounds incredibly illegal.
Okay so that was a joke about CP, but unironically HDCP should be illegal
Any Digital Restrictions Management *MUST* be illegal. Period, full stop, enough said

Also it is wasting their money for something that barely works.

I hate it when my CP isn't HD.
He lives in Canada. FBI doesn't have jurisdiction there!
Yea they do, they have jurisdiction everywhere, this gun says so!
As a Linux user, I'm concerned that I do not really 'own' my hardware when such restrictions are in place. I'd be happy to use old technology to circumvent this ridiculousness. Either that, or I'll use the decryption outlined in the video regardless of what content I'm viewing.
you can use displayport
@@SAMISHUKRIdisplay port also uses HDCP
Love the sarcasm, if anything HDCP is causing people to download pre-ripped content due to all the problems it causes. As always thanks Linus you da best!
Wow, Techquickie seems to have totally missed the point. HDCP being a lousy software protection protocol, isn't at all important to the manufacturers. The fact that they can change it on you and make you buy everything (all from the one supplier to guarantee compatibility won't be an issue) is what it's all about. They don't even have to change anything. Imagine your system was working fine, but your old TV gets stolen or is irreparably damaged. New devices will have a new HDCP standard. You have to replace not just the TV, but EVERYTHING! Phones, cables, xbox PlayStation, everything! In order to get your system going again. This has nothing to do with copyright protection. It's corporate greed trying to force you into a very expensive way of dealing with them.
It never ceases to amaze me how stupid people are these days: Apple admitted updates slowed old iPhones when the new model came out. This should have bankrupted apple years ago. That's what would have happened when I was a child. Not any more, people just accept this crap. So expect to see a lot more things like the HDCP scam in other industries.
Imagine if you took your new car in for a service that is required to maintain your new car warranty. A new model of that car is released, so they deliberately make your car run richer to reduce it's performance and fuel economy. Would you buy another car from that car maker? What about if they stuff up the wheel alignment so it pulls left all the time? Or any one of dozens of other irritating things they could do. It will happen the way things are going, because that is what is happening today in other industries. Stop rewarding bad behavior of businesses obviously trying to unscrupulousness scam you, don't buy from them before it becomes an accepted practice in that industry.
Yes like the self repair barrier apple enforce
Correct its a nightmare. For example, my perfectly good but old DVI Monitor just will not work when connected to an HDMI PC. Spent a fortune on adapters, splitters, strippers, converter cables etc. but always a blank display even when just trying to use Windows, let alone movies and stuff.
A curse on Intel
Thanks for spelling it out Linus, I almost spewed my tea all over my desk.
lol high-bandwidth digital content protection or SHIT for short. Linus 2017
I couldn't understand why I was occasionally seeing snow on an HDMI input when I switched my 4K TV to my allegedly 4K capable FetchTV STB, so thanks for the explanation. HDCP sucks, particularly when I only ever use the STB to watch free to air TV or catch up TV!
Fun fact. Netflix's hdcp-compliant streaming can be circumvented easily by disabling hardware acceleration... The more you know
I'm surprised you guys didn't mention one of the most frustrating problems with HDCP, users that have monitors over 120hz cannot watch content on HDCP-compliant streaming or devices. I cannot watch Netflix if my monitor is set to 144hz, sometimes to the point where even if I change it and try again it still doesn't work, so I have to restart my PC.

Are you using Chrome? It might just be a Chrome problem if you're not. I did research into it and found a post on the Chromium bug reports forums and this has been an issue since it was first reported in 2014.
_bad I use Pale Moon.
What if you just bit-for-bit clone the encrypted media? It'd be impossible for any receiver device to tell the difference. Similarly, what if the decryption chip in even a single receiver device gets dumped and shared online? The entire premise of HDCP seems fundamentally flawed but it's somehow a serious thing made by very serious people at Intel and it really exists so I'm confused.
Pretty stupid. Causes more issues than solutions. Actually still not a solution, since there are almost always multiple sources of content (dvd and stuff).
Companies need to face the fact that there will always be pirates. Any protcol or anything protection they make will eventually be broken, (I've seen cases where software was cracked and out before the official release). If there is a new protection method it may hold for a year or 2 at the most like Denuvo, with that after one game was cracked after 6 months, games started getting cracked left and right. Maybe they have a slight increase in the amount of sales while the security isn't broken, but most people pirate anyways are more likely willing to wait.
Azenix Roblox I pirate a lot of stuff but its mainly because I don't trust it properly. Like mafia 3 for example... otherwise I buy most of my games. I've also pirated The Grand Tour too as even though I have an amazon prime subscription the shitty DRM that covers all but one of my monitors is just annoying and its genuinely easier to torrent it, hell you can even watch as it downloads. Pirates would never have bought it to begin with.
Azenix Roblox Resident Evil 7 with Denuvo was released last week, cracked 5 days after launch. Companies are wasting their time
Harry Phillips wasting time and paying consomer's money...
If I genuinely like something than, i'd be happy to pay for it, the best part about torrenting movies and stuff is that I can use VLC and have all sorts of different controls like speed.
I have seen software cracked and bugs corrected by the pirates. Cracked one worked better☺
Thank you for this video 🙌🏼 I had issues with my Nintendo switch having this error with an older tv I hooked it up to on vacation and out of all the Nintendo switch “help” videos THIS one had my answer. Thank you for this content!
How could you miss that handshake fails at 144Hz... A bane to all of us with nice overdriven TN film Gaming displays... I have to run at 120Hz just in case I accidentally load netflix or something that tries to force a handshake.
HTPC does not prevent you from copying a bluray.
That is the AACS encryption, like CSS was the encryption method for DVD.
The nexflix example was correct though.
If you want to copy a bluray, you need to disable the AACS encryption
The Blu-ray player has HDCP though
Movies on Itunes won't play in HD because of HDCP and now the sound cut out too. I have an lg 24" ultrawide monitor and a custom-built pc that is fairly new. Why does Itunes not let me watch my movies?
Since the TV gets the full resolution stream, couldn't a recording device pretend to be a TV too (for example, spoof any identifiers along with using a compatible encryption key)? Surely the encryption key could be extracted from a TV.
That's what pirates do, they decrypt BluRays using jailbroken PlayStation 3's.
Linus knows all about that HD CP.
I've used my 42" Toshiba flat screen for my PC for many years now(I think the TV was bought back in 2012). Even when I had 2 tv's(for L4D2 multi local), one with HDMI and the other with DVI-to-HDMI adapter, I never had any issues.
Honestly this is why I like component cables still existing for now. Oh you still spit out 1080i and 1080p over analog? Lel. The amount of times I could have gotten by DRM and HDCP = to the amount of times it has screwed legit stuff
I had a problem earlier with this. my fix was to turn off and on the TV. another way to record stuff is through a different source like TV most set top boxes have RCA inputs so use that to record
when i watched this 2 weeks ago it was interesting, but last week my mum got a new TV and her Amazon fire stick was all fuzzy and messed up, she thought it was the stick dying, soooooo, i got her to watch this and told her "I think the stick is fine, i have a feeling that it's the S.H.I.T (HDCP) that's doing it" so she got an HDMI splitter as you suggested and it's working fine now, good timing on the video!!
did anyone else get the S**T on 1:03 ?
NOOOOOOOOOOOOOOOO.... no.
Nooooo... Nobody immediately got that joke. Linus doesn't know how to spell.. Nah nah nah nah!
High-Bandwidth Digital Content Protection - aka S.H.I.T. Couldn't have said it better myself Linus, and I wrote a paper on this!
At the start I was asking myself? Since when we can't copy original BluRay or Netflix content. Then I watched the whole video and turned out, Linus knows what he talks about.
1:04 this is why I love you Linus (no homo)
I like that "also stands for 's-h-i-t'"
My favorite Death Grips album 0:44
This is exactly why I download all my movies. I have so many unopened blueray and dvds in my cabinet.
Ah a fairly large RUclips channel that isn't automatically pro-tech-drm-type-shit. How refreshing. Loving the bluntness here :D
My 4K ASUS monitor doesn't support HDCP 2.2, so the only 4K content I can actually watch is you, Linus.
When you dont understand any of what Linus is saying, but you watch anyways.
Darian Mccants lol true, i am only reading the comments, i dont pay attention to what linus is saying
Eh, I understood most of it, and I'm not a DRM expert by any means.
Maybe try rewatching the video to pick up things you missed the 1st time, and use your googlefu to pick up on some new concepts ;)
If your freesync monitor is going black sometimes while freesync is enabled using HDMI, disable HDCP. It fixes this issue(October 2020)
3:25 Priceless
1:03 I like how he spells it
Corporation with a lot of money: "Let's put all these frustrating anti-piracy measures into our products!"
Pirates: "Oh no! Anyway..."
Paying customers: "Why are we still here? Just to suffer?"
actually the reason that dumb splitters do not work with HDMI also has to do with the DVI/HDMI digital signaling itself. Matched signal pairs with very high frequency signaling just don't like being passively "split". It can work in some very niche situation. Think identical monitors. Short cables.
However S.H.I.T aka HDCP would get in the way in this case anyway.
I had to refund a 4K movie because the resolution was capped at 480p... If anything, this faulty content protection standard would entice consumers to pirate their content instead of spending money on it
It has given people problems because that is *all it does*. Its only function and feature is to break functionality, because some companies imagine that makes them more money. For a handful of lawyers it even does, but certainly not for producers.
Best. Spelling Bee Attempt. Ever.
Capture Card through OBS.
Did anyone else see that at 4:28 Linus said "a splitter" but showed the oposite (multiple inputs, one output)?
1:36 What? I've ripped plenty of Blu-Rays without any sacrifice to quality.
Seriously though, if you're using capture software/devices rather than something like HandBrake to rip Blu-Rays, you're doing it wrong.
He's talking about Blu-ray players, that use HDCP and HDMI.

Very Nice Bro

Sheez, Linus looked so angry at 3:21!
HDCP is meant to protect digital content from unauthorized devices as well as Man-in-the-Middle attacks. However, it is also flawed as there are videos and tutorials as to how to bypass HDCP.
BIOS on a TV?
yep
bios of a pc that is plugged into the tv with hdmi
linus what would make it possible for my smart tv to record on demand content such as netflix?
Anyone here from the new Techquickie? I hate these types of comments but someone has to do it
Haha yes XD
How does HDR work? Is it just a term for displays with a high contrast ratio?
That is why I had to put a HDMI switch between my TV and DVR. without it the DVR actually overheats and crashes often. but the switch is getting old and needs replacing, unfortunately the one I got to replace it doesn't block the HDCP signature and doesn't fix the problem.
1:03 Echoes Act 3 confirmed as Linus' Stand
I hate HDCP for Amazon and RUclips.
I love how they don't tell you if you are HDCP streaming compliant until AFTER you buy the HD version of something.
What does it d increase security or something
You should make a video on why composite needed 4 cables (YRGB)
3:20 If the bios were unlocked in a TV, we would see a LTT video titled "Overclocking my TV part 1/4"
Watching this video on a HDCP-stripped signal because of the wonderful HDMI-splitter trick :)
1.05 was so unexpected i burst out laughing
i use my laptop for screen mirroring and i use it for Fire TV Stick but the problem is NOW TV uses HDCP and it says that my tv is not HDCP enabled (non-compilant) but i can do it with my NOW TV box, i'm not trying to pirate anything i only want to watch it on a bigger screen.
When I first built my computer I was using a Display Port cable and Amazon wouldn't allow me to watch Prime content because of HDCP. It wasn't until I replaced it with HDMI cable that I was able to. I've got an Amazon Fire TV 4K and you need a compatible HDCP 2.2 TV, HDMI ports, and audio system.
4:51 No wonder he's upset his TV isn't working. It's not plugged in!
The manufacturers learned nothing from the mp3 era... The only people inconvenienced were the people who really bought the cds (Duh!) at the time. I've had handshaking problems before. Some of my friends who owned PS3 Blu-Ray had the problem as well... How did they solve the problem? I will leave it to your incredible imagination...
Shout out to linus using a picture of a hdmi switch and calling it a splitter.
linus u do a great job and its coll as well keep up the good work
will you do a video on

So the tv needs to support hdcp 2.2 for the 4k blu ray player and 4k disc to work?
And Nvidia Shadowplay can access the framebuffer of your Nvidia gpu and record everything that your dislay shows
Weird. I ve only ever hears of this ... on techquickie. Ive never personally experienced this. Why? I connect my laptop to lots of TVs. Old, new... doesnt matter. Works just fine.
I wonder if this is my problem. I've been recking my brain trying to figure out why I can't stream some content from my computer to my tv. I'm not using a hdmi cable but I am getting inconsistent/intermittent handshaking problems and issues playing certain file types?...
Any suggestion for a good splitter?
Ok. iPhone 6pluss, netflix account, and appleTV. Before iOS 11 was released I was able to use iPhone and my Netflix account to download Netflix shows onto my phone - then screen mirror thru AppleTV to project the show onto my television's bigger screen. With the first iOS 11 download that stopped. Now.. it all works the same except the last step. Meaning- I can see Netflix account mirrored from iPhone onto the tv while I am selecting my downloaded show.. but the minute I hit play on the show my TV screen goes black. I suspect (now) that it is HDCP... any tips to make this work again?
I just purchased a Denon A/V receiver. One of the things I wanted to do was use my receiver to listen to real time audio editing using my Win 10 PC. The receiver and laptop don't handshake due to HDCP between the laptop and receiver. Is there a way to get the receiver and laptop HDMI to communicate?
3:40 get yourself a powered splitter
Just a basic question, looking for help. I just bought a new TV that is HDCP 2.2 and my UHD player is HDCP 2.2 as well. However, my audio receiver is older and only accepts optical input. Will I have HDCP video issues if I use the optical out to my older receiver?
This is kinda confusing me.. So do I need to upgrade my reciever to a newer one
You should make a video about internet browsers other than Edge, Internet Explorer, Firefox, Chrome and Safari. I have used Opera a bit and think it's neat, but I've also tried some other lesser known browsers such as Lunascape6 and Cyberfox.
How are these other browsers different from the more commonly used ones. For instance Opera has a built-in ad blocker, and Lunascape uses 3 engines (as noted below).
Also in what ways do rendering engines such as Gecko (Firefox), WebKit (Safari), and Trident ( Internet Explorer) differ?
The big companies were paying spies to watch the torrents and who was downloading and uploading. Seemingly they made random selections of normal every day people and went after them with legal action with enormous life destroying fines to make public examples of how serious they take media theft. They might be moving away from this approach because of the bad PR it gives but still I can't see piracy worth the risk anymore. I wouldn't doubt if they started taking legal actions against these "hand shake" bypasses.
It's just like the trucking industry. The EPA started slamming crippling environmental restrictions on the trucks making truckers install extremely expensive smog reducers. Well when those reducers fail it's a lot easier/cheaper for the owner to delete (hack) that system off the truck. But now the EPA has a tampering snitch program and they do take legal action against companies.
It's hard to escape that long arm of the law especially when it seems like the technology we find so fascinating is being turned around and used against us by the government/powers to be.

6 years ago. What a time to be alive both then, and now. Still I'm here annoyed with HDPC. I was actually looking for Anaglyphic3d/stereoscopy solutions for an old 3D tv, since games like Batman: Arkham City might support it. Let's hope so.
I've tried playing legally paid for movies through itunes or google play on my ipad and output that video (w/ adapter) to the analog screens in my car for the kids and get blocked every time. The interesting thing is that without a splitter, it works just fine with this setup with downloaded content from both amazon video and netflix. Why does it work with those apps and not with itunes and google play?
does display port has a negative technology like hdcp ?
