    RE: http://www.engadget.com/entry/1234000143050582/

    This article goes into detail about Windows Longhorn's need for monitors whose inputs are either HDMI or DVI with HDCP. If your monitor is not up to spec, and most of them are not, or is analogue, you are going to get downscaled HD content.

    It's part of Microsoft's new DRM system built into Longhorn called PVP-OPM (Protected Video Path - Output Protection Management).

    Its not just microsoft that want to block content, its pressure from the content owners too (HD-DVD/BluRay films for example).

    "The Windows XP COPP implementation of HDCP has some limitations. It only reports the KSV of the first connected display, and therefore it cannot play content if a repeater is present. With PVP-OPM in Longhorn, the entire tree of display devices and repeaters is found by the vendor-supplied driver. This includes displays on the other side of repeaters. "

    DOH!

    to stop piracy.

    No point having bluray players with HDMI protection for the home, if your bluray player on your PC is outputting an unprotected digital signal.

    http://www.theinquirer.net/?article=24638 explains how Intel's East Fork (EF) is going to be the hardware component of the M$ DRM world.

    Interesting about the UK's exclusions, wonder if that's to do with BSkyB?

    Or put another way - this is to allow BluRay/HD-DVD replay on PCs. Without HDCP or similar technology on a PCs video output, there is no way copyright holders would allow their pre-recorded material to be played on a PC...

    Presumably the BluRay/HD-DVD replay software for PCs will be sealed tight as well - with any 3rd party software provider having to sign-up to the relevant industry bodies (and thus agree to play by the rules?)

    man this is a bummer - I have a 24 inch widescreen monitor - Sony W900 which looks great with HTDV TS - so now to watch HD on longhorn I would have to use an inferior LCD monitor?

    Yep, it's a hardware and software combination.

    Some people speculate that Intel's hardware DRM component (built into the CPU) is one of the key reasons Apple announced their processor switch from IBM to Intel, so they could ensure next gen HD content would play on their hardware.

    Linux, as The Inquirer article points out, is screwed because it will never gets rights to play BluRay / HD-DVD.

    Don't know if AMD are going to be putting the same DRM tech in their processors, but I would guess so otherwise they might not be any HD content from them either.

    http://www.latimes.com/business/la-fi-micro17jul17,0,3776901.story?coll=la-home-business

    This article from L.A. Times is primarily about Microsoft's movie ambitions, but includes details of Advanced Access Content System, known as AACS, from joint goup of companies including tech firms Microsoft, Intel Corp. and IBM Corp.; media companies Warner Bros. and Disney; and consumer electronics companies Panasonic, Toshiba and Sony.

    AACS will be the copy protection for BluRay / HD-DVD.

    Also ... seen those posts about new HD-DVD and BluRay players having ethernet ports? The AACS spec allows these new HD devices to have dynamic software too.

    "The system would also allow the AACS group to reach into the house and change software if the system got hacked to produce unauthorized copies. That's a level of control rarely seen before the latest video game consoles."

    Im not looking forward to having to buy yet another monitor.

    Still im sure companies like dell will be looking forward to this.

    New OS equals new PC.

    To enforce DRM im sure we will also require a 24/7 internet conection. This may also become true for Blu Ray and HD DVD players.
