AACS, a system to be used in both HD DVD and Blu-ray Disc (BD) players, will require that those players downconvert video over their analog outputs. But only if the studio decides to use this feature.
… the affected analog signal must be “down-converted” from the full 1920×1080 lines of resolution the players are capable of outputting to 960×540 lines—a resolution closer to standard DVDs than to high-def. Standard DVDs are typically encoded at 720 horizontal by 480 vertical lines of resolution.
The 960×540 standard stipulated in the AACS agreement represents 50% higher resolution than standard-def, but only one-quarter the resolution of full high-def. Whether a particular movie is down-converted will be up to the studio.
I have a feeling that every studio will end up using this “feature”. Though if this “feature” is used, it’ll be specified on the movie’s packaging, which is a good thing. It’s like a warning that you’re about to be smacked upside the head. At least you can brace yourself for it.
