Constrain This, Pal
"Image Constraint Token." A piquant phrase, yes? Roll it around on your tongue a few times before I tell you what it is. OK, ready? It's the name of the flag that will down-res HDTV in the soon-to-debut Blu-ray and HD DVD formats under the rights management scheme known as AACS (Advanced Access Content System). The restriction will apply only to the player's component video outputs, because they're analog, and therefore give the studios security nightmares. If your HDTV has HDMI, you needn't worry. HDMI is digital, easier to protect, and will work at full resolution. But if you're an early HDTV adopter and component is the only HD input on your set—ouch. The Image Constraint Token will halve resolution from 1920 by 1080 pixels to 960 by 540. It is an option, not a requirement. Studios likely to use it reportedly include Disney, NBC Universal, Paramount, and Warner. Fox has argued against it and Sony hasn't taken a position. The logic behind the ICT is staggeringly faulty: Does anyone really believe that cutting resolution in half will stop pirates in their tracks?
