Dolby Digital Plus is a highly sophisticated and versatile audio coding based on Dolby Digital and
designed specifically to adapt to the changing demands of future audio, video delivery, and audio
storage systems while simultaneously retaining backwards compatibility with the existing Dolby
Digital 5.1-channel home theater systems in use today.

The Dolby Headphone technology provides a surround sound listening experience over
headphones.
When listening to multi-channel content such as DVD movies over headphones, the listening
experience is fundamentally different than listening to speakers. Since the headphone speaker
drivers are covering the pinna of the ear, the listening experience differs greatly from traditional
speaker playback. Dolby utilizes patented headphone perspective curves to solve this problem
and provides a non-fatiguing, immersive, home theater listening experience. Dolby Headphone
also delivers exceptional 3D audio from stereo material.

Dolby Digital identifies the use of Dolby Digital audio coding for such consumer formats as DVD
and DTV. As with film sound, Dolby Digital can provide up to five full-range channels for left,
center, and right screen channels, independent left and right surround channels, and a sixth
(".1") channel for low-frequency effects.
Dolby Surround Pro Logic II is an improved matrix decoding technology that provides better
spatiality and directionality on Dolby Surround program material. It provides a convincing three-
dimensional sound field on conventional stereo music recordings. While conventional surround
programming is fully compatible with Dolby Surround Pro Logic II decoders, soundtracks will be
able to be encoded specifically to take full advantage of Pro Logic II playback, including separate
left and right surround channels. (Such material is also compatible with conventional Pro Logic
decoders.)
