Default Re: HDMI 1.3, Connectivity Issues?

To Bob,

I don't think we are saying different things. I think maybe I just need to be clearer.

I am saying that if you were to take an HD-DVD player with a source HD-DVD encoded in VC-1 1080p and output that as either 1080i or 1080p to a 1080p HDTV with a good deinterlacer then the net result will be the same on the screen.

The reason being that the 1080i signal contains all the same digital information that the 1080p signal does since both originate from the 1080p source. All the same data is there and therefore you are not losing anything as long as your HDTV recombines the interlaced signal back into progressive properly.

I agree for sure that 1080i source material and 1080p source material would show a difference especially as the display gets larger.

I could point to numerous threads on other forums that explains why this is so. It was hashed and rehashed to death in the earlier days of the BR / HD-DVD war since Sony was pumping the fact that it output 1080p versus the HD-DVD's 1080i, but the reality was there was no benefit.

This doesn't even take into account the fact that the initial BR players converted the 1080p source to 1080i and then back again before outputting it anyway which effectively introducing a similar number of processing steps as you would find in an HD-DVD player outputting 1080i to a 1800p HDTV, but just at different locations in the signal path than the Toshiba's. Oh the irony.



PS. seeing people now hyping the HDMI 1.3 as a big bonus if you also have an HDMI 1.3 processor lol. I guess it allows for you to send the raw (don't know how else to say it) advanced audio codecs like True-HD 7/8.1 to the receiver to be processed their instead of the player. Not sure why you would want to do that unless the player cannot do the processing. You lose SAP functionality and any other audio overlays in the process.
