Roland Vlaicu, Senior Director of Broadcast Imaging at Dolby Labs, explains the key elements of Dolby Vision, a technology that greatly increases the dynamic range and color gamut in video content and displays. He talks about how high dynamic range and expanded color gamut more accurately represent how the real world looks, bandwidth requirements, backward compatibility with current displays, the ability to accommodate to the capabilities of the display, when we might see Dolby Vision displays and content, answers to chat room questions, and more.

Scott,

Great show as usual! One question that I thought would come up that didn't was how about front projectors?

since I didn't see this live, my question would've been, can Dolby Vision be utilized by Avegant's glyph head mounted display which is using Texas Intruments pico DLP mirrored chip which delivers low powered colored laser rays directly to the retina? Somebody needs to get Avegant and Dolby together on this. It would blow Occulus and Sony away!

The Avegant Glyph uses a low powered broad LED light source similar to a normal DLP projector. It just projects directly into your eye rather than onto the front or back of a screen. It is not like a "typical" virtual retinal display with a rasterized image created by a scanning laser.

Great interview! Roland spoke very convincingly of Dolby Vision. He managed to he very technical and understandable at the same time. And he didn't appear to dodge any questions with deviant answers. 

The future sure looks promising. Dolby really thought this through in a way that will be compelling to manufacturers, studios and consumers alike.

 

I just wonder about one thing. They say that Dolby Vision will be delivered through an enhancement layer that adds about 20% bandwidth to an existing 8-bit rec.709 source. So those 20% will contain up to 4-6 extra stops of dynamic range, 50% more color space, and 10-bit dithering?

 

I know it won't have to add all these things simultaneously, only when they are required of the source, but it still seems like a bit of a tall order. I wonder what the compromises are.

Interesting. I only saw content delivery addressed as far as streaming. Is streaming the only content delivery system currently lined up? What about the other limitations of streaming and how they affect picture quality?

Saw this demoed and it was very impressive smile.gif

I also want to see Dolby Vision applied to OTA broadcasts which I can watch with my ghetto htpc set-up., I'm too poor to afford blue ray purchases and streaming services. Still not clear to me where Dolby Vision gets applied in the video production chain? The source camera output? The broadcast signal? My tuner card? The GPU chip renderer? The monitor display chipset?

Amazing conversation, I learned a lot!

I brought friends to see what it  Dolby's Vision 

 

But there are some things to ask with your permission:

 

1. You said the screen is very bright and can damage vision / Eyes ? 800 NIT ?  Particularly a problem in a dark room ?

 

2.Is there a danger of radiation from the screen ? 

 

3. How to see online SD on 4K resolution ? 

 

4.When Sharp / tcl  Going On With Dolby's Vision Screen  ?

 

5. Do I need a video card support to Dolby's Vision ( Like DX 12 Need a special driver )  ?

 

6. Do I need to player in my computer to support Dolby's Vision Better ?

 

7.how do you do  calibration to Dolby's Vision tv ? with disc ?

 

8. Is this method works Like deep coloer 12/16 bit from Sony?

 

Again many thanks for the interview

yeah good point, what about front projectors? there has been a lot talk about LED, OLED, and so on and so on but not much talk on projectors? could we see more videos on Projector tech and the likes relating to projectors, much appreciated ^_^


Also I am looking forward to seeing this tech in person one day. smile.gif

I live in the Valley Village area, is there anywhere I can go to see a demo of all of this in person? is there anything setup at the Dolby Theater?

Great show, would've liked to hear if Dolby Vision will find it's way into projectors?

Don't worry about projection. In fact, don't be surprised if projection is the first technology able to deliver the full promise of DolbyVision. Laser projectors already heading to market will be capable of the high brightness and color gamut requirements of DV. Of course, initial units will be quite expensive.
