How Does HDCP Work?

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.

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.

[@japzone]

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😉

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.

[@divyangvaidya1999]

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.

[@amiri7392]

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.

[@VeyronBD]

[@martinherald6492]

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.

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.
