Formerly called Digital Theater Systems. The current name is Dedicated to Sound.

The logo is in widescreen (as you can see here).

I have some DVD's that has this logo (if I select the DTS option), such as Bruce Almighty (2003). But, to hear the audio on DVD, you need the right equipment (otherwise, if you don't have the right equipment, such as a decoder, or a DVD player that can decode DTS audio, it's silent).
