HDMI to DVI -- Is this a workable approach?

Hi

I've got a Hitachi rear projection set (1080i) that I'm not ready to replace. However I would like to get a Blu-Ray player.

The Hitachi RPTV has a DVI input.

What I'd like to know is:

(a) whether I will get good results by integrating a Blu-Ray player using an HDMI-DVI cable; and

(b) how should I connect the new Blu Ray player such that the video signal goes directly to the TV via the HDMI-DVI cable, while the audio signal goes to my AV receiver?

I know these are dumb questions... but help would be appreciated.

All best
Rappahannock

Re: HDMI to DVI -- Is this a workable approach?

You should be fine using a HDMI to DVI cable. DVI cannot carry audio, so you would have to connect a separate audio cable to your amp. Obviously, if you use digi-coax or optical, you're restricted to vanilla audio formats such as DD5.1 and DTS but that's no great shakes. All bluray players will have digi-coax and/or optical. The PS3 has optical output only and to be brutally honest is the only bluray players I would touch. The format is a mess with profile updates (PS3 is currently the only profile 2.0 player although there is little or no software that supports it), expensive players and most importantly expensive movies. Obviously you'll need to check the specs of your player. I presume it's not a new HDMI equipped amp you're connecting to?

dvi only carries video signal anyway, so the sound will have to travel down a different cable so it can terminate at either your tv or the amp, the only snag you may run into is lip sync bit this can usually be compensated for in

Re: HDMI to DVI -- Is this a workable approach?

Thanks for those replies.

For Dave Puma, I would be running the audio output from the Blu-Ray player into a 4 year old Denon mid-range A/V receiver. Presumably, I could use the digital audio out from the Blu-Ray player -- if there is in fact a dedicated digital audio out -- to the digital audio input in the receiver.

This leaves open the question as to where the audio signal processing takes place -- in the Blu-Ray player or the receiver. Any advice on that issue?

The lip-sync problem is one I hadn't thought about. What can/should be done to fix it?

Again, thanks for your time.

You would set the player to output bitstream so the receiver does the decoding. All bluray players will have digital audio outputs, not everyone has a HDMI receiver. You might not get any lip sync issues but this can usually be compensated for in the receiver if it has that feature.

I am thinking about it. According to the Hitachi manual for my TV, the DVI input supports broad band digital copy protection v 1.0. Any view on whether this does the trick?

Many thanks

If it does not work then you can get a "Naugthy box" - thats a box that removes the HDCP.

Best to try HDMI to DVI first
