HDCP: DVI Version 1.0 vs HDMI 1.1. What is the difference?

Posted by Alex F. (A) on June 27, 2005 at 13:50:28

Greetings, guys:

I'm considering the purchase of a new, leftover Hitachi RPTV (a CRT unit, the 65S500), which has a DVI input using Version 1.0 copy protection.

I've noticed that Hitachi's newest TVs utilize HDMI inputs, and the copy protection is Version 1.1.

The DVI-equipped TV has superior picture quality compared with their RPTV that uses an HDMI input (the CRT-based 65F710). In case you're wondering, I still prefer CRTs over current microdisplay units (DLP, LCD, etc.).

My questions: Will HDCP Version 1.0 prohibit me from viewing DVDs (via the video digital connection) that Version 1.1 will pass unhindered? How about the upcoming high-definition DVDs? Or DirecTV's upcoming, revamped HD system? My concern is about near-term obsolesence of the DVI digital video connection (the digital audio portion is not a worry).

Finally, does HDMI offer any video-quality advantages compared with DVI?

Thank you in advance for your help!

Alex
