On the consumer level, DTS is the oft-used shorthand for the DTS Coherent Acoustics (DCA) codec, transportable through S/PDIF and part of the LaserDisc, DVD, and Blu-ray specifications. This system is the consumer version of the DTS standard, using a similar codec without needing separate DTS CD-ROM media.
