>DisplayPort 1.0 includes optional DPCP (DisplayPort Content Protection) from Philips, which uses 128-bit AES encryption. It also features full authentication and session key establishment. Each encryption session is independent, and it has an independent revocation system. This portion of the standard is licensed separately. It also adds the ability to verify the proximity of the receiver and transmitter, a technique intended to ensure users are not bypassing the content protection system to send data out to distant, unauthorized users.
WHY THE FUCK WOULD YOU ENCRYPT A FUCKING VIDEO CABLE?
Because if you have a good antenna, you can catch the electromagnetic waves my by the cable, which means you can remotely see what someone has on a screen, including sensitive data.

To be fair, if you have the capabilities of picking up what's being sent through the cable, then you're most likely the NSA or similar, and if you ARE the NSA or similar, you can also break AES 128.
Samuel Ross
if you want to place an antenna next to the cable that would mean you have physical access to something that the cable is connected to because it cant be longer than 10 meters
- if you have physical access to the machine: you won just install your botnets on it no one can stop you.
- if you have physical access to the monitor: just fucking look at the monitor you dumbass. or put a camera next to it or something
there is no point
David Kelly
fuck. i accidentally used reddit spacing. it made more sense when it was in the small quick reply box
Daniel Collins
Don't exactly know how this tech is called, but I saw a proof of concept - a simple antenna in the radius of 10-20 meters allowed receiving the signal being sent to a CRT monitor and that was 20 years ago. I bet you can buy this shit relatively cheap in a spy shop and that cops in every police office have one.
Dylan Sullivan
lol no
Jace Williams
just listen to their radios
Thomas Edwards
Yeah, seeing people's mails, creepy porn, trade secrets are totally not worth it.
Jaxon James
read the whole thing not just the last line, tyrone. i know reading is hard for you because they didn't teach it to you in nigger school but try harder before replying.

>slowly enforce DisplayPort inputs in monitors and GPUs >hook up with VR industry and push the VR meme and its need for Display Port >becomes so widespread it's adopted as a competing standard with HDMI with little formal announcement >kneecap it with encryption worse than HDCP
But you know, you can listen the signal through walls, do you?
Wyatt Clark
I have never used display port what did I lose?
Zachary Rivera
Higher bandwith (unnoticeable unless you have an 8K monitor) Different protocol (unnoticeable) 1 extra pin (unnoticeable) Different connector (not very noticeable) With DisplayPort you can disable the video output so you can just have audio through it if you care You can connect more than one monitor to your GPU with 1 DP cable and a hub DP is royalty free but you probably dont care DP has a locking connector so you cant yank it out accidentally because that apparently happens
All it takes is one bad actor making a "splitter" to make the whole DRM nonsense a farce
Ian Johnson
>DP is royalty free but you probably dont care holy fuck hdmi costs at best 40c per device
Joseph Parker
>$10,000 per high-volume manufacturer plus $0.04 per device Don't tell the FBI but I have an illegal HDMI controller on an ASIC hidden in my stash safe under the floor boards and I don't plan on paying them the $0.04.
Carter Williams
Except that it refuses to use this mode unless the content being viewed is not sensitive and can be watched by anyone for a few bucks.
Jose Hill
Love it how something as innocent as a splitter completely breaks their DRM scheme.
Bentley Sanchez
Is this 2005 or something?
Jack Wilson
>DP is royalty free but you probably dont care For members of VESA which requires yearly payments and an IP contract to control what you do when you implement it
Gavin Collins
Incredibly wrong. There are many, many environments (every US military classified network for example) where someone could quite possibly get one time access where they aren't going to be allowed/able to even plug in a usb drive - and even if they did HBSS would almost certainly catch it, and they aren't going to be able to leave with the machine. They probably won't have a login or be left alone. > if you want to place an antenna next to the cable that would mean you have physical access to something that the cable is connected to because it cant be longer than 10 meters 10m is wrong, but also, how is it so hard for your tiny brain to imagine multiple relayed devices? > if you have physical access to the monitor: just fucking look at the monitor you dumbass. or put a camera next to it or something A camera facing the screen will be obvious, an antenna behind the screen on the cable is far more likely to go unnoticed. It's almost like they'd want to see what the person does in the future and not a static image of what happens to be on their screen as the person walks by one time. Holy shit how stupid are you. You sound like a 14 year old or NEET so all of this is useless

There are 2 annual fee structures:
High-volume (more than 10,000 units) HDMI Adopter Agreement - $10k/year. Low-volume (10,000 units or less) HDMI Adopter Agreement - $5k/year + flat $1/unit administration fee.
The royalty fee structure is the same for all volumes. The following variable per-unit royalty is device-based and not dependent on number of ports, chips or connectors:
US$0.15 for each end-user licensed product. US$0.05 – If the HDMI logo is used on the product and promotional material, the per-unit fee drops from US$0.15 to US$0.05. Use of HDMI logo requires compliance testing. US$0.04 – If HDCP is implemented and HDMI logo is used, the per-unit fee drops further from US$0.05 to US$0.04. _____________________________________ The cost of HDCP includes the adapter annual fee, the HDCP key cost used in the products, and the HDCP testing fee of the product model.
The member annual fee is US $15,000 per year. About the fee of HDCP keys, the price will vary with the purchase quantity: Purchase 1,000,000 keys at a time: US$ 10,000 (0.01 each) Purchase 100,000 keys at a time: US$ 5,000 (0.05 each) Purchase 10,000 keys at a time: US$ 2,000 (0.2 each)
so let's say you're some chink tv manufacturer it amounts to literally 0.15+0.05+0.04+0.05=$0.29 + flat fee you need to eat up
ok you are superior to me in every way possible now please no reddit arguments in my thread thanks
Matthew Sullivan
>If the HDMI logo is used on the product and promotional material, the per-unit fee drops So that's why they plaster HDMI stickers on my monitors. In the earlier days of HDMI this would be a big selling point but now it's just assumed to be there, so advertising it is like putting "has wheels" as a selling point for a car.

Because it pleases (((publishers))). Doesn't do anything to stop piracy when anyone can just use an on screen recorder
