Dolby Atmos in home theater

Dolby has now developed the technology required to translate the Dolby Atmos experience

in cinema to home theaters. In the case of the home theater, every sound in the mix is

represented as an audio object. What happens when you play a Dolby Atmos film, whether

from a Blu-ray Disc™ or a streaming video service, is quite remarkable. When you set up

your Dolby Atmos enabled A/V receiver (AVR), you'll have informed your receiver how many

speakers you have, what type of speakers they are (large, small, overhead, and/or Dolby

Atmos enabled), and where they're located. Your receiver will decide—in real time—exactly

which speakers it needs to use from moment to moment in order to reproduce the sounds

of the car careening across the screen and the child fleeing up the stairs. That detailed, very

specific movement of sound helps your brain suspend disbelief and feel as if what you're

watching is real.

The flexibility of Dolby Atmos object-based sound makes it incredibly adaptable. A Dolby

Atmos movie can be played back on nearly any speaker configuration in the home. You'll be

able to hear the placement and movement of sound in a Dolby Atmos movie whether you

have a system with five speakers on the floor and two overhead, or 24 speakers on the floor

and 10 overhead (the current maximum for a Dolby Atmos supersystem). The more

speakers you have, the more precise the audio positioning becomes.

And you have lots of flexibility to upgrade your system. If you add more speakers, your AVR

can use them to provide you with even more detailed, richer sound.

Delivery of Dolby Atmos movies

Major Hollywood studios are partnering with Dolby to create Dolby Atmos home video

versions of current box office releases and previously released favorites. In addition to

global studio partnerships, Dolby is partnering with game, music, and broadcast content

creators to take advantage of Dolby Atmos technology for future home theater use.

We wanted to ensure that entertainment fans could get Dolby Atmos movies in the same

ways they get movies now, on Blu-ray Disc or through streaming video services.

We invented a new, scalable algorithm as well as new extensions for our existing

technologies, Dolby TrueHD, which is Dolby's lossless Blu-ray™ format, and Dolby Digital

Plus™, which is used by leading streaming video providers or for secondary languages on
