DTS (also known as Digital Theater Systems), owned by DTS, Inc., is a multi-channel digital surround sound format used for both commercial/theatrical and consumer grade applications. It is used for in-movie sound both on film and on DVD.

One of the company’s initial investors was film director Steven Spielberg, who felt that theatrical sound formats up until the company’s founding were no longer state of the art, and as a result were no longer optimal for use on projects where quality sound reproduction was of the utmost importance.

The Matroska Multimedia Container is an open standard free Container format, a file format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows.

Matroska is an English word derived from the Russian word “matryoshka” (Russian: матрёшка, IPA: [mɐˈtrʲoʂkə]), which means “nesting doll” (the common Russian egg-shaped doll within a doll).

Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound, with five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz – 120 Hz) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48kHz.

Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and Present Danger featured the very first Home theater Dolby Digital mix in 1995.
