ATMOS有两种CORE,分别是truehd和dd plus,分别用于碟片媒体和流媒体,在碟片菜单里的BD-LIVE音效也是DD PLUS。没错,你的算正确点亮了。
Dolby Atmos isn’t sound, it’s information about sound. That information piggybacks on top of existing surround sound signals. At the moment, Dolby Atmos can only do this with two types of surround sound signals: - Dolby TrueHD
- Dolby Digital Plus
Dolby TrueHD is a lossless, very high-bandwidth format that is currently only available on Blu-ray and UHD Blu-ray discs. It’s transmitted over an HDMI cable, from a Blu-ray player to an AV receiver, TV, or a soundbar that can pass through the video. Dolby Digital Plus is a lossy, lower-bandwidth format that has been optimized for use with streaming services and features like B-D Live. It’s currently supported by a wide range of devices, including laptops, tablets, smartphones, and streaming boxes like Apple TV and Roku. Dolby Atmos over Dolby Digital Plus will be the way most people experience Atmos.
