In Reply to: Re: HDCP: DVI Version 1.0 vs HDMI 1.1. What is the difference? posted by dhrab on June 28, 2005 at 04:48:02:

Thank you for the link, Dave. I found it helpful.

I did some additional research since my initial post. I have been told by DirecTV that their all-new, upcoming HD system is expected to be compatible with DVI-equipped televisions.

Also, both Hitachi and Pioneer assured me that as long as a television has any form of HDCP, it should be compatible with either DVI or HDMI DVD players (i.e., standard-def players). Hitachi added, though, that compatibility between current HDCP Versions 1.0 and 1.1 and future hi-def DVD players remains unknown, because standards are still unresolved.

Pioneer stated that as far as absolute high-definition video quality goes, HDMI has theoretical advantages that may or may not be noticeable with typical RPTVs. The rep said the difference likely would be moot with a television that can display up to 1280 x 720 maximum resolution. HDMI thus becomes more important with televisions that can output 1920 x 1080.

Finally, from looking at info at HDMI.org, it seems that the difference between HDCP Versions 1.0 and 1.1 is that the latter was developed to support DVD-Audio.
