Progressive Scan

Juas..

Resulta que el chip de nVidia si es capaz de procesar Progressive Scan para las pelis DVD, pero MS no lo incorporó en la consola por miedo a problemas legales con MAcrovision, ya que el chip de Conexant que tiene la Xbox no está capacitado para soportar los esquemas de proteccion de Macrovision.

Es decir, la empresa que portó su software para la reproduccion del DVD en la Xbox, Ravisent Cinemaster, no incorporó las primitivas para el Progressive Svcan, pero la version de PC de su software si las hay.

Con lo que a ver si alguien se atreve a programarlo y podemos habilitar el Progressive Scan para el DVD de la Xbox.

Otro punto a favor para el lector DVD de la Xbox!![poraki]

>>>The Xbox also has its hands tied, but for different reasons. You see, Nvidia's GPU is quite capable of decoding a DVD movie and outputting a progressive-scan picture, but Microsoft chose to focus on only progressive-scan picture within games, not movies. Someone just needs to write such capability into the software. Blackley jokes, "We thought that we'd piss off manufacturers by making a better DVD player."<<<

They make it sound as if they wanted to add it, but didn't have time. Fact is, the software that was ported to Xbox for its DVD playback (Ravisent Cinemaster) has progressive scan support on PC, and that support was REMOVED for the Xbox version.

Why would they do that? Simple. The real reason is that the Xbox's Conexant CX25871 video encoder doesn't have support for the AGC 1.03 version of the Macrovision copy protection scheme. (the 480p version of Macrovision) It only supports the 7.1.L1 version of Macrovision (the latest 480i version). Enabling progressive scan playback on Xbox would get MS into serious legal trouble with the MPAA and others. It will have to be an independent hack.
