BD+ Cracked

[ps3hacker]

The newest beta of Anydvd Hd can copy BD+ titles. 10 years really gone by that fast?:) Halarious!

EDIT... It seems there readme is a little mis leading. It says there ripper supports BD+ but it now just rips the approprite folders. The file protection still remains so no altering of streams.

quite right :)

Amusing to watch this rumor spread.
But then again it's not sooo untrue, considering that this first wave of BD+ implementations turned out to be a a toothless tiger.

Peer, so BD+ disks ripped can only be played with PDVD or other players have the same "bug" ?

[lightshadow]

Does anyone know when Transformers and Spiderman was released? It could be fun to update http://en.wikipedia.org/wiki/History_of_attacks_against_Advanced_Access_Content_System

Perhaps even with a section of BD+, now that progress is happening.

Standalones have been reported to work just as well...
Not so sure it's a bug in the players, but more a careless coding of the BD+ data on the discs.

"Oops" :) Now that I've built my new HTPC, this issue has more meaning to me. I'm glad that BD+ has so far turned out to be a non-issue. We'll see how well they do next time around.

[noclip]

So BD+ discs can be copied by mass commercial pirates with no problems, but not viewed in an open source player. Sony really has their priorities straight.

There are BD+ (Cars 2006 720p BluRay x264-REVEiLLE) being posted in the internet. This mean the groups must of stripped the BD+ to encode the source into the x284/mkv?

Can someone explain what is going on with this one?

[honai]

Could be a fake, or the disk didn't actually have BD+.

Please read forum rules. Don't double post (http://forum.doom9.org/showthread.php?p=1063545#post1063545).

[Blue_MiSfit]

I bet it's still possible to do things the REALLY hardcore way - HDMI out through an HDCP stripper to a HDMI -> HD-SDI converter -> HD-SDI capture card -> capture and encode...

Brutal...

[honai]

The device keys for those strippers have been revoked already.

[enantiomer]

honai,
Where did you hear that? I have two old HDCP strippers in use on two different Blu-ray players around the house. One display is on old NEC plasma and the other is a Dell 2405FPW monitor. They're working just fine even with the latest titles.

Except that title didnt have BD+. No BD+ title has been encoded to any other format.

Is there a PC fast enough to capture the uncompressed raw video feed that passes through HDMI. We are talking about really high bitrate here...

not unless you have a ram drive card with over 8gigs of space just for a buffer for a nice raid-0 with at least 10 15k SCSI drives in the chain

Yes, but HD-SDI hardware is mainly used on HD studio productions with multiple $100,000+ cameras, so you can imagine what it costs.

The datarate required for raw uncompressed "1080p24" is ~71 MiB/s. My 50eur, 200GB samsung hard drive sustains 30-55 MiB/s. Three of them in parallel should do the trick for capturing a two-hour movie. My computer (Athlon XP 2400+) certainly has no trouble capturing uncompressed rgb PAL at 31 MiB/s. With a Core 2 processor you could throw in some lossless compression (HuffYUV is very fast).

[Shinigami-Sama]

here I'm thinking 1080p@60

[noclip]

The datarate required for raw uncompressed "1080p24" is ~71 MiB/s.

I'm curious as to how you calculated that.

1920 x 1080 = 2,073,600 pixels
2,073,600 pixels x 24 bits per pixel is ~6 MiB per frame
6 MiB per frame x 24 frames = 144 MiB per second (unless of course you're using 4:2:2 YUV, in which case it's roughly 95 MiBs per second).

You'd need 5 of those drives to sustain such a data rate. At that point, a few 15K RPM SCSI or SAS drives would make more sense. As a side note, you can actually get a single SSD that will sustain that kind of transfer rate, but a 3.5" 128GB one costs $5,000.

[Shinigami-Sama]

SAS drives are cheap, the controllers can be had for last I checked $600 and that had 15 connectors, and raid0,1,5 capabilities and I believe 128megs of battery backup cache, so for as little as $3500 you could have the hardware to do it, iuno how much those HDCP remover costs though...


but this is starting to get a little off topic..

You only need 12 bits per pixel because the video stored on the disc is 4:2:0 (although you need a color space conversion from the captured digital RGB values). 2,073,600 * 12 * 24 = 597,196,800 mbit/s ~= 71 MiB/s. On the other hand, I don't know how destructive a color space conversion is (in other words, whether the conversion from 4:2:0 to RGB done by the player can be reversed back to 4:2:0 without any losses). I guess it depends on what kind of a matrix was used.

you said uncompressed
yv12 is still compressed, its just raw

[reepa]

Movies on Blu-Ray and HD-DVD are 4:2:0. Capturing them as 1080p60 RGB would be pointless. Besides, I said you could throw in some lossless compression.

[HyperHacker]

And of course if you don't mind spending the extra time, you could play the video repeatedly, first capturing say every third frame, then every third offset by one, etc (so first 1, 4, 7... then 2, 5, 8...) and reassemble it into a video. Timing might be difficult though.

[bcrabl]

Hmmm. I don't know a thing but virtual graphics cards drivers are completely out of question? I think the drivers must be signed, but is there anything we could do about that?

[honai]

No. And it's not just the driver but also the video card BIOS that is checked.

[3r1c]

Since the AACS and HDCP requirement has been cracked, is the signed driver still a requirement?

I know on windows vista the signed driver requirement has been cracked using a bootkit.

You don't.

No, it hasn't.

We're talking about video card BIOS here, not mainboard BIOS.

And the article is totally unrelated to this thread, and Blu-ray/HD-DVD DRM as it is currently implemented is also totally unrelated to Vista DRM.

To put it bluntly, every word in your post is wrong, including "is" and "has". ;)
