In addition to Dolby Digital, there is the similarly functioning digital surround system Digital Theater System (DTS). Like Dolby Digital, DTS was initially developed for cinemas. It was first used for the blockbuster "Jurassic Park" in 1993 when Steven Spielberg opted for the system jointly developed by Panasonic and Universal Studio.
DTS-HD Master Audio
An identical reconstruction of the studio master allows DTS-HD Master Audio through extremely high sampling rates and resolution. For movies on Blu-ray Discs, DTS-HD Master Audio currently has the widest distribution of all audio formats. The comparable competitor format is Dolby TrueHD. With DTS-HD Master Audio, various data rates (up to 24.5 Mbit/s on Blu-ray Disc and 18 Mbit/s on HD-DVD) can be run. The channel count ranges from 7.1 at 96 kHz/24 bit to 2.0 at 192 kHz / 24 bit.
All game consoles, such as the Playstation 4 or XBOX One, support internal decoding of DTS-HD Master and output via HDMI as an uncompressed multichannel PCM signal.
What do you need to play DTS formats?
Again, you need an AV receiver, which converts the DTS format and passes it on to the individual speakers as an analogue audio signal.
