Hi guys,

just wanna ask fews questions

I'm planning to upgrade my non HDMI AVR to new AVR to enjoy HD audio.
But now with 3D come around, should I wait and upgrade to 3D capable AVR later
or just upgrade now with AVR without 3D, I believed I read somewhere that 3D
will use HDMI v1.4.
If I want to enjoy 3D, I need to upgrade AVR, TV & bd player 3D capable?
or just upgrade one of these?

I think TV and player need to be capable; AVR not so much (except maybe HDMI version)

TV and BD player is a must upgrade in order to enjoy 3D. But for AVR, it is no necessary cause you can choice BD player that got 2 HDMI output (eg.: Panasonic 3D-Ready BD player, etc.). So, 1 output connect you BD player to 3D-Ready TV with HDMI 1.4 and another output connect to HDMI in non 3D-Ready AVR.

Unless you use PS3 as player than you only need to upgrade TV to 3D-Ready TV (max. fps you can select is 24p if you use HDMI 1.3 and AVR also not need to be 3D-Ready)

thanks

So far the only 3D BD player in the market that has HDMI 1.4 and 1.3 out is the Panasonic. The rest just use ONE HDMI out.

Right now we don't know how this is going to work. It could be that there is enough bandwidth for 3D at 720p while still delivering lossless sound (encoded or decoded).

My advice is to wait until the new 3D-capable receivers arrive. Pioneer have already announced theirs. The VSX-920-K and VSX-1020-K should be available by July.

As far as the claims of FullHD 3D is concerned, I don't know if that is possible with a 1920x1080 resolution screen. Consider this anaglyph image.


The full resolution of this image is 800x630. But take into account that the blue image is for the right eye and the red image is for the left eye. If you separate the two images, you'd see that their horizontal resolution is no longer 800.

The same is true when a 3D BD movie is played back on a current fixed screen 3D HDTV. Each left and right eye information as stored on the disc are 1920x1080; this is necessary because when the disc is played back on a non-3D BD player or TV, it must display all 1920x1080 pixels. However, when it is played back on a 3D HDTV with a 3D BD player, that horizontal resolution must be rescaled to fit 1920 pixels; this downscaling may also affect the vertical resolution as well.

To get the full resolution, the flat screen panels and even LCD/DLP imaging chips must have slightly more horizontal pixels than what they have now.

are you saying that 761px image you posted is not really 761px? or that somehow it's bigger than a 2D 761px image?

anyhow if you were transmitting these, you'd digitally superimpose them onto a resulting single frame of whatever resolution they are supposed to be, no? so that a 3D 1920x1080 frame contains the same number of bytes a 2D 1920x1080 frame does.

No, I'm not saying that.

That is what I'm saying. A 3D image is made of two 2D sources. To include both images, the horizontal resolution must be slightly bigger than 1920.

The two images are not superimposed until they are delivered to the 3D HDTV. The 3D HDTV will decide how to show each frame using whichever technology it employs.

Will have to experiment with Photoshop to verify my hypothesis.

Each time I watch a 3D movie..
easily got headache

Here is review for Panasonic's Full HD 3D Blu-ray products. Maybe you will interested.

First look: Panasonic's Full HD 3D Blu-ray products

In this review, you will noted Panasonic BDT300 3D Ready BD player got 2 HDMI outputs ("HDMI Main AV Out" and "HDMI Sub AV Out"), by using this player, you only need AVR got HDMI input is enough instead of go to upgrade expensive 3D-Ready AVR.



Here is explanation:

I would hold the purchase now until there is clearer picture on the compatibility of equipment. Even 1st gen blu-ray player had compatibility problem with current newer BD profile disc without firmware to upgrade.

I would hold off buying first gen equipment but not for the above reasons. The reason why 1st gen BD player need firmware upgrade was due to it being rushed to the market (BD vs. HD-DVD).

3D BD discs must work on 2D BD players as well as 3D BD players. 3D BD players must work with 2D and 3D HDTVs/projector. 3D HDTVs must work with 2D and 3D signals. So far, 3D BD players comes with 3D software (Samsung comes bundled with Monsters vs Aliens while Panasonic came with a 3D sampler) so you know it works.

Don't forget Sony Expo 3D 2010 tomorrow

very good discussion & explaination
can help newbies like me to understand more
about this 3D thingy

looks like i will proceed with my AVR purchase
and no need to wait for 3D avr

I guess you're intent on buying the Panasonic 3D system then. Because anything else may not work with a regular receiver.
