Don't all HD players feature HDCP?

[dougzer0]

this guy is talking out his ass, right ?

"During Vista's development, Sony and the MPAA demanded that Vista include the HDCP encryption tunnel (which microsoft was forced to develop). Microsoft made an arrangment with Sony, that if they put the HDCP tunnel in Vista, then blue-ray's must have HDCP encryption by 2010. Right after microsoft made this arrangment, they fully backed and supported HD-DVD. And since the HDCP tunnel does exist within Vista, Sony is now required to put HDCP on blue-ray's by 2010, or Microsoft will sue them. In other words, Microsoft purposefully played Sony's arrogance against them, and now they will be forced to put HDCP on their own media, which will most assuredly tank it (because HDCP is ****ing retarded)."

don't all blu-ray / hd-dvd players already implement HDCP and isn't it up to the studios' discretion to enable the image constraint token (ICT) to limit content ? Without the ICT flag set, players will send the full 1080p signal to any display device whether it is HDCP compliant or not ?

this guys a tool all blu-rays and hd dvd have hdcp every single disc players will only send like 567p to players or 480p or somthing if it dosent have hdcp. and intel made desinged hdcp by the way. and mircosoft had to make hdcp on vista or els hd dvd would and will not play lmao microsoft picked hd dvd over blu-ray becuase hd dvd uses microsofts hdi and mostly vc-1. and microsoft said hd dvd playback was essire to intagrate into windows.

Yup.

Basically this is your talking point:

a) Neither Sony nor MPAA developed HDCP. So they cannot force MS to develop a HDCP pipeline in Vista.

b) While MS can opt out of HDCP, not developing one for Vista on the onset is sheer idiocy. Without HDCP, even MS's vision of downloadable HD content would falter because the studios would require copy protection that HDCP gives.

It is an economic decision for MS to support HDCP. Otherwise, people would clamor towards OS X/Linux.

Who cares what Sony has with VISTA...what I want to know is the bulls*** the NSA has hidden in VISTA.


....VISTA will never touch my computer.

Errrrr......... I installed Vista. Crap. So basically every move I make is being viewed/recorded?

Not inconceivable, knowing MS.

HDCP is an encryption over an DVI/HDMI interface. It's all handled by the DVI/HDMI transmitter.

The concepts that were forced into Vista were Protected Video Pathway - Output Protection Management (PVP-OPM) which is a way of protecting video data within the PC from being extracted by other programs and drivers, and Protected Application Environment (PAE) which requires the application to run only in the case where all system accessible applications are trusted.

Programs on XP, for example, can get full access to the memory, and thus could snoop keys, grap the decrypted data before it's put into a decoder, or grab the image frames. The original hacks to AACS were due to the lack of PAE on XP computers running software players allowing the keys to be extracted.

On Vista, the player application would run in a space inaccessible to other applications. And if a driver with protected mode access to the system is found to be violating media protection it will be blacklisted, and media won't play in the system unless that driver is disabled (that is, the user has a choice between the driver and the media).

Stand-alone players have PVP-OPM and PAE by the nature of not being general computing devices. The PS/3 can't access or play BD movie (or game) discs when it is booted in Linux mode.

Blu Ray and HD DVD's are very demanding on system resources for PC's. YOu need a good amount of memory and a fairly high level video card.
