The impact could be considerable for devices running the Plex and Emby ecosystems (multimedia server systems), as well as for those running Android and iOS. But in this case, the surround experience loses its luster, while the dynamic compression (Night mode) integrated into true Dolby Digital decoders is also lost.Īs such, the expiration of the Dolby Digital patent should allow these manufacturers to propose products which natively decode Dolby Digital audio tracks. It is thus not uncommon for multimedia players to process Dolby Digital by converting it to simple stereo format (downmix), which seems to be ok with Dolby.

The Sopranos, Six Feet Under and Lost are examples, and these series were broadcast at the turn of the century by HBO in Dolby Digital.
