Google will challenge Dolby by developing a free standard to replace Dolby Vision and Dolby Atmos



 

Google will challenge Dolby by developing a free standard to replace Dolby Vision and Dolby Atmos.

Internet giants such as Amazon, Cisco, Google, Intel, Microsoft, Microframe Visionular, Mozilla and Netflix officially established the Alliance for Open Media on September 2, 2015.

The alliance aims to create new opportunities for next-generation multimedia experiences by developing new, open, royalty-free video coding standards and video formats.

The first tax-free format introduced by the alliance is the AV1 video coding format.

At present, Intel ARC and NVIDIA RTX 40 series graphics cards already natively support AV1 codec, AMD’s upcoming new graphics cards will also provide native support, and the adoption rate of AV1 format is gradually increasing.

And now, Google has its sights set on HDR and 3D audio standards.

YouTube is the most popular video site in the world, Chrome is the most popular browser in the world, Android is the most popular operating system in the world, and anything Google wants to launch can instantly have a sizeable clientele, servers and The user base of the content, including video and network standards, will only solve the problem of getting some partners to keep up. This is how the AV1 video codec is promoted.

 

According to Protocol, Google is working on a Project Caviar initiative to create a tax-free new standard to replace Dolby World and Dolby Atmos through the Open Media Alliance .

Dolby‘s old media business model relied on royalties from hardware manufacturers and support from content creators, the company’s technology is deeply embedded in movie theaters and Blu-ray films, while modern streaming companies like Apple are Dolby big supporter.

It all costs money, though, and Protocol reports that a $50 streaming device such as a Chromecast that supports Dolby Vision and Dolby Atmos would cost Dolby Labs at least $2 Patent royalties.

 

The biggest improvement of Dolby Atmos compared to the previous Dolby Surround is the addition of overhead channels , providing users with a stronger sense of surround in all directions.

Dolby Surround has only one flat 2D dimension, while Dolby Atmos adds a third vertical dimension, so it’s called Atmos or 3D Surround, Apple, Netflix, HBO Max, and Disney+ all support Dolby panoramic sound.

 

 

We understands that the new standard does not require the development of new codecs. Google’s strategy is mainly to standardize the way audio and video data is transmitted, without paying Dolby fees, and branding it so that it can be easily compete.

First, the group has published specifications for the “immersive audio container” online, describing it as a “codec-agnostic audio bitstream format to provide a three-dimensional sound field that can be used for multi-channel sound playback”.

For HDR, the group hopes to adopt the HDR10+ standard, originally developed by Samsung, to bring Dynamic HDR to the HDR10 standard while maintaining the benefits of royalty-free but lacking content support.

 

It’s not known what consumer-facing brands these standards will be used for, which is a big question since the “Dolby” name still holds a lot of power among home theater enthusiasts, meaning streaming apps Dolby branding can be marketed as a premium add-on, creating demand for these standards.

Few companies have enough clout in the media space to push for a new standard, but Google is expected to change that.
