22、爱 好者资料库 2 DTS was introduced in 1994 to provide 5.1 channels of discrete digital audio into home theater systems. DTS brings you premium quality discrete multichannel digital sound to both movies and music. DTS is a multi-channel sound system designed to create full range digital sound reproduction.

23、 The no compromise DTS digital process sets the standard of quality for cinema sound by delivering an exact copy of the studio master recordings to neighborhood and home theaters. Now, every moviegoer can hear the sound exactly as the movie- maker intended. DTS can be enjoyed in the home for either

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 fu

25、ll-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 tech- nology that provides better spatiality and directionality on Dolby Sur-

26、 round program material; provides a convincing three-dimensional soundfield on conventional stereo music recordings; and is ideally suited to bring the surround experience to automotive sound. While conventional surround programming is fully compatible with Dolby Surround Pro Logic II decoders, soun

27、dtracks 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.) Dolby Digital EX creates six full-bandwidth output channels from 5.1- channel

28、 sources. This is done using a matrix decoder that derives three surround channels from the two in the original record- ing. For best results, Dolby Digital EX should be used with movies soundtracks recorded with Dolby Digital Surround EX. Manufactured under license from Dolby Laboratories. “Dolby”,
