The Digital Theater System Digital Surround (simply called DTS) is a multichannel digital signal format that
can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are 5.1 channel
media formats, discs bearing the “DTS” symbol are thought to provide better sound quality due to the lower
audio compression required.
It also offers a broader dynamic, producing magnificent sound quality.
