Dolby Atmos

Dolby Atmos® is an immersive audio format that can be delivered via multiple audio codecs including Dolby Digital Plus and Dolby TrueHD (but NOT Dolby Digital). Blu-ray Discs deliver Dolby Atmos using Dolby TrueHD (with Dolby Digital Plus as an available alternative), and broadcast and streaming services deliver Dolby Atmos using Dolby Digital Plus. In order to maintain compatibility with millions of devices in consumer homes, Dolby Atmos in these codecs is implemented as a backwards-compatible extension. Dolby Atmos data is hidden within the bitstream and can be decoded by a Dolby Atmos-compatible A/V Receiver, soundbar or television. Non-Dolby Atmos capable devices will decode a 5.1-ch or 7.1-ch version from the Dolby Digital Plus or Dolby TrueHD bitstreams.
