What type of sound technology does a DVD use?

Digital Sound
Discs with digital sound offer high quality range, clarity and sound quality. Audio for most movies is stored as discrete, multi-channel surround sound using Dolby Digital or DTS audio compression similar to the digital surround sound formats used in movie theaters.

Dolby Digital
Dolby® Digital technology is an advanced form of digital audio encoding that makes it possible to store and transmit high-quality digital sound far more efficiently than was previously possible. It is currently the surround sound used in most movie theaters and for DVD-Video and Blu-ray.

Using Dolby Digital Plus, Blu-ray can allow for up to 7.1 channels of high definition surround sound.
