The DVD title must carry one or more primary audio tracks in AC-3 or LPCM format (in Europe, MPEG-1 Layer 2 is also an allowed primary track format). The DTS audio track, if present, can be selected by the user. Modern DVD players can now decode DTS natively with no problem, or pass it through to an external decoder. Nearly all standalone receivers and many integrated ("home theater in a box") DVD player/receivers manufactured today can decode DTS.
A small number of Laserdiscs carry DTS soundtracks. The NTSC Laserdisc format allows for either analog audio only or both analog and digital audio tracks. Laserdiscs encoded with DTS sound replace the LPCM digital audio track with the DTS soundtrack. This soundtrack is output via digital coaxial or optical audio outputs and requires an external decoder to process the bitsream. Consumers without a DTS decoder are only able to listen to the analog audio tracks on the disc.
For PC playback, many software players support the decoding of DTS. The VideoLAN project has created a decoding module for DTS called libdca (formerly libdts), which is the first open source implementation of DTS.[1]
The Sony PlayStation 3 and Xbox 360 are capable of DTS decoding and output via Toslink or HDMI as LPCM. However, HDMI output on the Xbox 360 is only found on the "Elite" model and newer models available since mid-2007 with the release of the 'falcon' chipset. Only the PlayStation 3 console has the ability to decode DTS-HD Master Audio or High Resolution since the newest firmware update, ver. 2.30 and up.
