![]() ![]() I can think of a couple HD-DVD disks that were released totally unencrypted with no AACS bits. These rights are both bitmasks on the video streams, and additional rights data in the encrypted XML data files on the disks. So most often you get to view the trailers and extra filler on disk in 540×900, but are not authorized to watch the main feature at all. It is still better then 640×480 (or 720×480 – remember that TV pixels are not square, but are at 4:3 ratio, so depending on what your scaler does, resolution might differ) resolution of a Standard Defenition (SD) video signal, but you paid for 1080p, right? This is up to the studio, however, and very few are liberal enough to allow you even that. If you have component or analog out, you might be lucky, and video studio will let you watch the same video in a “pleb” 960×540 resolution. If you have DVI outputs, well, you get 1080i (1920×1080, interlaced, but it’s OK, because output is 60Hz, and most decent HD TVs and monitors will do proper deinterlacing, in essence outputing 1080p). “Degradation” in plain terms means that if you have HDCP path to your monitor/TV, you will view content in it’s 1080p (1920×1080 resolution, deinterlaced) glory. In essence, if your video card doesn’t support High Defenition Content Protection (HDCP), and if your monitor is not connected to your video card over DVI or HDCP, but over analog or component outputs, your viewing experience will be “degraded”. Specifically, AACS mandates that a viewer should not be allowed to watch HD output from software player if there is an unencrypted path between the player and the video output device. AACS is non-exclusively licensed by AACS Licensing Authority, and restricts what a buyer (in essence a long term renter of a right to watch) of a HD video disk can do. HD-DVD (and Blu-Ray) drives are part of the security layer designed by Advanced Access Control System (AACS), a new generation in viewer rights restriction, that successed Content Srambling System (CSS), implemented on DVDs. When I learned that Microsoft released an add-on to Xbox 360, consisting of an HD-DVD drive in an external USB-accessible enclosure, after some penny pinching, I took the plunge and bought it. I’ve been eyeing the HD stuff with a bit of curiosity, and pretty much convinced myself to step up to HD production. ![]() One of my fields of interest is video making. ![]()
