Downsampling grain?

[Deciazulado]

I think the PS3 when it gets scaling abilities it might be able to do 720p in the following signal path:

1080 x 1920 24p content -> add 3:2 repeats -> 1080 x 1920 60p -> downscale to 720 x 1280 60p

1080 x 1920 60i content -> deinterlace -> 1080 x 1920 60p -> downscale to 720 x 1280 60p


The paths in blue would be the new abilities. Right now it has be doing the "1080 x 1920 24p -> add 3:2 repeats -> 1080 x 1920 60p" part because it outputs 1080 x 1920 60p while 60i material remains 60i interlaced.


Also then it would do

720 x 1280 60p content -> upscale to 1080 x 1920 60p


same for 480 i,p content, etc etc

We'll see...


In the current situation the player sends a 1080 x 1920 60Hz interlaced output from both film and 60i content for displays that only accept 1080i, and the display has to deal (deinterlace/scale) with that.

As Chad mentioned going 1080 -> 720 -> 768, or 1080 -> 540 -> 720, or 1080 -> 540 -> 768, etc has several steps where noise/degradation could happen.
Maybe with the scaling other resolutions might be added. And Zoom for those that don't like black bars...
