However, Dolby Atmos bitstreams are encoded to be backwards compatible with Dolby Digital Plus decoders, and as such Dolby Atmos can be decoded by Dolby Digital Plus compatible devices. This has been marketed by Dolby, as the lossy compression variation of Dolby Atmos under the label "Dolby Digital Plus Atmos" to differentiate it from the lossless DolbyHD-based original. Most Dolby Digital Plus bitstreams are now encoded in Atmos encoding.
