Dolby Digital

Dolby Digital is the next level of the Dolby Surround sound system that was developed for 35 mm-film movies by employing low bit-rate audio coding.

Dolby Digital is a digital surround sound system that provides completely independent multi-channel audio to you. Dolby Digital provides five full-range channels in what is sometimes referred to as a “3/2” configuration: three front channels (left, center and right), and two surround channels. A sixth bass-only effect channel is also provided for output of LFE (low frequency effect), or low bass effects that are independent of other channels. (This is called the “LFE channel”.) This channel is counted as 0.1, thus giving rise to the term 5.1 channels in total.

Compared to Dolby Surround, which is referred to a “3/1” system (left front, center, right front and just one surround channel), Dolby Digital features two surround channels, called stereo or split surrounds, each offering the same full-range fidelity as the three front channels.

DTS Digital Surround

By using the built-in Dolby Digital decoder, you can experience the dramatic realism and impact of Dolby Digital theater sound in your home.

The wide dynamic range of sound reproduced by the five full- range channels and precise sound orientation by digital sound processing provides listeners with excitement and realism that have never been experienced before.

Dolby Digital forms 5.1 channels as already mentioned, but it can also form fewer channels, for example 2-channel stereo and monaural. You may be able to find some 2-channel stereo and/or monaural sources encoded with Dolby Digital in the market.

Laser disc and DVD are home audio/video program sources that could benefit from Dolby Digital. In the near future, Dolby Digital will also be applied to DBS, CATV and HDTV. The ongoing release of Dolby Digital theatrical films now underway will provide an immediate source of Dolby Digital encoded video software.

DTS (Digital Theater Systems) was developed to replace analog soundtracks of movies with six discrete channels of digital soundtracks, and it is now installed in many theaters around the world. The DTS digital playback system changed the way we experienced movies in theaters with six discrete channels of superb digital audio.

DTS technology, through intense research and development has made it possible to deliver similar encode/decode discrete technology to home audio surround-sound entertainment. DTS Digital Surround is an encode/decode system which delivers six channels of master-quality, 20-bit audio; technically, it is 5.1 channels, which means 5 full-range (left, center, right and two surround) channels, plus a subwoofer (LFE) channel (as “0.1”). It is compatible with the 5.1 speaker configurations that are currently available for home theater systems.

The DTS Digital Surround algorithm is designed to encode the six channels of 20-bit audio on to some laser discs, compact discs and DVDs with considerably less data compression.

By using the DTS decoder built into this unit, you can experience the dramatic realism and impact of the DTS- installed theater’s high quality sound in your home.

Laser disc, compact disc and DVD are home audio formats by which DTS can present its high-quality multi-channel audio. (In addition to movies on laser discs, many exciting new multi- channel music recordings will also become available in the form of DTS-encoded compact discs.)
