3D-Ready?

I also thought the reason the new 3d BD players with 1.4 HDMI ports have a second HDMI port is so one can go to a stereo, which cannot pass through the bandwidth used for 3d video in 1.4. So one goes to the TV and one hdmi cable to the stereo. 1.4 can handle 1.3 data, but not the reverse (which make sense and probably what you are saying anyway, so I'm just babbling at this point.)

I think you might misunderstand. "True" 3D at 1080P resolutions requires sending separate information signals for your left and right eye, which together add up to more bandwidth than is capable on a 1080P link.

So, you can get 1/2 resolution 3D with HDMI 1.3 or you can get full resolution 3D with HDMI 1.4, a compatible player, TV, shutter glasses, etc.

This is a very half empty perspective. The FACT is that frame compatible 3D has the exact same amount of information as 2D HD. They are not reducing the amount of data to the brain. Sure it would be better if they doubled it, but the 3D effect is a more notable improvement to consumers than doubling the pixel count.

The best quality 3D sources available is 3D Blu-ray which is 1080p 24 per eye. This is roughly the equivalent of 1080p48, which is LESS data than 1080p60, so yeah HDMI 1.3 has more than enough bandwidth.

Saying your device is HDMI 1.4 means it definitely supports 3D (as well as other features), but that does NOT mean that a TiVo with HDMI 1.3 does not support full HD 3D.

Bottom line is the that frame compatible 3D will work on the TiVo, but probably not full HD 3D, just not because it isn't HDMI 1.4. Full 3D HD via cable hasn't even been spec'd yet, but it'll probably be H.264 using the new Multiview Video Coding codec, which I doubt the TiVo Premier will ever support.

I thought I'd read somewhere that since HDMI 1.3 has enough bandwidth for 2D 1080p60 that 3D 1080p24 movies would also work (assuming the TV was designed to process input format; but bandwidth wise it would work as "1080p48 equiv" is less than 1080p60).

(In that case it should be half the resolution or half the framerate)
