DTS - Digital Theater Systems - is a proprietary [[multichannel]] format developed and marketed by Digital Theater Systems. Its official name is DTS Coherent Accoustics. It's a standard audio format in DVD, next to Dolby [[AC3]] and [[LPCM]]. It was extended for Blu-ray (and HD-DVD) into [[DTS-HD\|DTS-HD Master Audio]].

	~~It's a standard audio format in DVD, next to Dolby [[AC3]] and [[LPCM]]. It~~ uses considerably high bitrates, ranging around 760-1500kbps for multichannel programs. That has led some people to believe it delivers better quality than AC3, that works at bitrates up to 640kbps. Dolby retorts claiming DTS needs such high bitrates because it uses primitive and inefficient technologies for audio data reduction. A consensus on which format is better has never been established.
