Dolby Digital

Dolby Digital is the reigning standard for surround sound technology, and the common version in most homes contains 5.1 channels (five primary speakers and a LFE channel). Dolby Digital supports both Mono and Stereo. Before Dolby Digital there was the Dolby's Pro-Logic format. Dolby Digital can be found in many cinemas as well as DVD / Home cinema systems.

DTS

DTS stands for 'Digital Theater Systems' is an audio encoding format similar to Dolby Digital. Most DVD support both of thes formats. Many people claim DTS sounds better than Dolby Digital, but experts feel it's almost impossible to compare the two formats. This is because of the differing volume levels.
