THere are three ways on which Atmos metadata can be conveyed:Дolby Digital Plus is a channel based format in its own right and different to Dolby Digital. THe receiver would detect it if present and indicate that you are receiving Atmos if the receiver is set to an appropriate mode that is compliant with the portrayal of Atmos and if your Atmos enabled AV receiver has a speaker configuration compliant with Atmos.ДЄtmos is facilitated by metadata and this metadata is package within other audio formats. SKY encode all their UHD broadcasts using DD+ and DD+ would also be the format in which Atmos metadata is packaged if Atmos is available via Sky's services.ДD+ is bitstreamed to your receiver irrespective of whether it contains Atmos metadata or not.

Streaming services and TV broadcasters tend to use DD+ as opposed to TrueHD for their audio encoding and to convey Atmos because iof the lower bandwidth it requires.

The Dolby MAT 2.0 container is scalable and leverages the full potential of the HDMI audio pipeline. The Dolby MAT 2.0 decoder in an AVR outputs the object-based audio and its metadata for further processing. Among the possible sources are broadcast set-top boxes, PCs, and game consoles. With the introduction of Dolby Atmos, we have expanded this technology to support encoding of Dolby Atmos content as lossless pulse-code modulation (PCM) audio.ДЄ key benefit of Dolby MAT 2.0 is that Dolby Atmos object-based audio can be live encoded and transmitted from a source device with limited latency and processing complexity. A MAT decoder is subsequently employed in an AVR to unpack the Dolby TrueHD bitstreams. The Dolby Metadata-enhanced Audio Transmission (Dolby MAT) encoder resides in a Blu-ray player to pack the variable bit-rate Dolby TrueHD bitstreams for transmission over the fixed bit-rate HDMI connections. The sampling rate for Dolby Atmos content is 48 kHz, the same sample rate as for Dolby Digital Pluscontent.Д«oth new audio decoders are designed to be fully backward compatible with legacy channel-based Dolby Digital Plus and Dolby TrueHD soundtracks. This module uses new bitstream metadata to extract Dolby Atmos object-based audio and outputs this information for further signal processing. Dolby Atmos audio can be encoded with Dolby TrueHD at multiple sampling rates (including 48 and 96 kHz) and bit depths (16- and 24-bit).Дolby Atmos enabled receivers will also support legacy Dolby TrueHD bitstreams at multiple sampling rates (including 48, 96, and 192 kHz) and bit depths (16-, 20-, and 24-bit) to provide full backward compatibility with legacy Blu-ray Disc media and Dolby TrueHD music files.Дolby Digital Plus has been updated and features a new decoder capable of processing content encoded for Dolby Atmos. If your AVR supports Dolby Atmos, the Dolby TrueHD object-based audio and related metadata will be decoded, processed, scaled, and rendered to your specific speaker configuration. Now we have added a fourth substream for Dolby Atmos sound in Dolby TrueHD codec to enable a support for a losslessly encoded object-based sound mix.Дolby Atmos in Dolby TrueHD is transmitted from a Blu-ray player or Ultra HD Blu-ray player to your AVR via an HDMI connection. Prior to Dolby Atmos, Dolby TrueHD provided lossless support for channel-based audio, such as 5.1 and 7.1. There are three ways on which Atmos metadata can be packaged:Дolby has expanded the Dolby TrueHD format to allow the format to support Dolby Atmos content on Blu-ray and ultra high definition Blu-ray Disc. Atmos is facilitated by metadata and this metadata is package within other audio formats.
