Just trying to get something clear in my head about the processing that the XA2 does. I know that to provide 1080p/60 output it interlaces then deinterlaces again, I'm just not sure at which stage it does this!!
The way I think it does this is that it reads 1080p/24 from the HD-DVD disc. It then processes this to 1080i/60. Then finally it deinterlaces this to 1080p/60.
If this is correct, then for comparison the PS3 when outputting 1080p/60, would read 1080p/24 from the Blu-Ray, then simply convert this to 1080p/60, without any interlacing/deinterlacing. Post the most recent update, it can simply read 1080p/24 and output this directly to the display.
The reason I'm asking is that I am interested in gaining 1080p/24 from HD-DVD, and Toshiba will (eventually) provide this functionality for the XA2 and A20 via a firmware update. If what I have written above is correct, then I'm thinking that post-update they will simply read 1080p/24 from the HD-DVD and pass this straight to the display, just like the PS3 is doing now.
The other possibility that I can think of is that the XA2 is reading 1080p/24 from the HD-DVD, and immediately converting this to 1080i/24, then converting this to 1080i/60, then deinterlacing to 1080p/60. To me this would be less preferable because post-update it would likely read 1080p/24 from the disc and immediately convert to 1080i/24, then deinterlace to 1080p/24. This would be less preferable to me as I feel that the least amount of processing is likely to preserve the optimum picture quality.
Does anybody know how the XA2 is performing this operation at present?
