Will A/V Receivers Need to Be 3D Compatible?

A/V receivers with HDMI switching could be a hindrance to the adoption of 3D because of their inability to accommodate the necessary extra bandwidth.

3D Blu-ray players such as this recently announced BDC6900 model from Samsung may create problems for A/V receivers and HDMI switchers.

A source from the Blu-ray Disc Association told CE Pro at CES 2010 that a possible speed bump in the road to greater adoption of 3D Blu-ray may not come from the TVs, players or content providers; it may come from A/V receivers and HDMI switching devices.

While HDMI 1.4 is in the specification for 3D Blu-ray, it’s not a requirement for sending a 3D Blu-ray signal from a player to a television. That’s why Sony’s Playstation 3 can be firmware upgraded to be 3D Blu-ray compatible while only having HDMI 1.3 built into its hardware. What is required is a minimum bandwidth allowance in order for the player to send the signal out to the TV.

A source told CE Pro that many A/V receivers with HDMI switching cannot accommodate the extra bandwidth. In other words, if you use your receiver for HDMI switching, you may not be able to connect it to a 3D Blu-ray player. The source said the BDA may be working with manufacturers to inform them of the bandwidth problem so they can help customers with questions and problems as well as establish a minimum bandwidth floor for receivers that will allow the 3D signal to pass.

One possible workaround the source suggested would be for Blu-ray players to include two HDMI outputs, one that would go directly to the 3D compatible display, and one to take the high-quality Blu-ray audio formats to the receiver.

Sony, Toshiba and Samsung are among those announcing 3D-compatible Blu-ray players at CES 2010.

All the more reason for MORE A/V receivers (and not just the fancy ones) to follow suit and allow for firmware upgrades via net connection.

What they’re not telling you is that HDMI 4.0 cables just happen to meet these bandwidth specifications, while all previous versions will not. :(  The runaround liveth!

Why not just have a specification that is compatible with existing tech? My set is 3d capable at 120hz right now. exactly why MUST we use 240hz. I’ll bet two video stream at 60 Hz through an hdmi cable is plenty sufficient and would work with most existing hdmi components. Maybe I’m wrong.

“I’ll bet two video stream at 60 Hz through an hdmi cable is plenty sufficient”

The refresh rate is a function of the display device, not the source component.

Just back from CES.  There is confision on this subject.  What is the actual bandwidth requirement?  Panasonic says HDMI 1.4 required for 3D.  HDMI org on a CE Pro call says 1.3 cables are capable of 3D.  Monster cables now labeled with 3D at bandwidths of 14.9Gb/s.  Will 10.2Gb/s cables not work?  Inquiring minds need to know.

Here we go again!  These 3D fads happen every few years.  And I predict it will be a short-lived fad; both in theaters and especially in the home.  Any 3D technology that requires the wearing of special glasses will be too much hassle!

This is stupid. I really don’t see any reason for higher bandwidth if the display is receiving the same refresh rates. The only thing i can think of is that they’re sending out extra data like encryption and information to the display for 3d purposes

I agree with Carl 100%.

In an episode of the Honeymooners, Alice asked Ralph why they didn’t own a TV. Ralph’s reply, “Because I’m waiting for 3D.”

The public just got done, (well most of them anyway), understanding and spending money on new flat panel TV’s, HDTV sat & cable hook-ups, & Blu Ray players.

I remember in the late 80’s when people began speaking of and asking about HDTV on the sales floor. We’d tell people that we didn’t expect anything for at least 10 years, but in some peoples minds, it delayed their purchase. Let’s all remember that history has a nasty way of repeating itself.

So what you’re saying is: Now that we have a one-cable solution for providing HD video and lossless digital audio from the source to the receiver, we’ll have to hook up separate cables for video and audio…?

Not sure what all these experts are talking about… but… looking at the GD-463D10 LCD-tv from JVC the 3D result is nothing less that flabbergasting, speachless, stunning, breathtaking and a lot more adjectives you prefer!

And I have a question for all readers here, why are you worried or interested in what type of cables you need to use? Imho this is a whole different ball game, a new product so to speak for those who want to get this technology in their home simply because you need a new player and new tv or projector with the exception of PS3 who can do with an upgrade. The cost of cables is second to none if you combine everything.

The Panasonic DMP-BDT350 will have two HDMI outputs. No word yet on the other manufacturers.

OH GREAT!

More utter confusion to be injected into the mix and ANOTHER HDMI spec.

It took years to get some consumers to finally buy into the HDTV and Bluray idea and now we are going to have to tell them that they are going to have to replace their displays, disc players, AV receivers AND HDMI cabling if they want to enjoy the latest “be all and end all”.

This is going to turn into a fiasco that will do nothing but make many sit on the fence and delay their new purchases. As if trying to stay afloat in this industry given the current climate wasn’t hard enough already.

sigh.

Phil,
See my post from 1/09… I couldn’t agree more.

More consumer electronics confusion…brought to you by the same people who couldn’t agree on a single standard for high def video discs. Here we go again! Oh, and lets have the early adopter serve as the free focus group to help us work through the bugs with the tech?!!??

I do not think this will be more then a fad,  too many people have just bought the HD sets for it to go main stream.
