Effective immediately, Dolby is withdrawing all limitations (including limitations contained in Dolby licenses) on the use of OEM (first-party) and third-party post-processing technologies (including upmixers and virtualisers) on audio decoded from Dolby formats (including Dolby Digital, Dolby Digital Plus, Dolby TrueHD, and Dolby Atmos) on AVRs, sound bars and TVs. Effective immediately, products submitted for approval before January 1, 2021 may apply first-party and third-party post-processing (including upmixers and virtualisers) to audio encoded in Dolby formats, including Dolby Digital, Dolby Digital Plus, Dolby TrueHD, and Dolby Atmos.
Dolby will provide guidelines for first-party and third-party audio post-processing of audio encoded in Dolby formats on AVRs, sound bars, and TVs, submitted for approval after January 1, 2021. These guidelines will be further specified in upcoming development manuals. The guidelines are not intended to limit the use of first-party and third-party solutions with Dolby codecs.
