DTS Surround

DTS Digital Surround

DTS Digital Surround is the standard digital surround format of DTS,

Inc., compatible with a sampling frequency of 44.1 or 48 kHz and up

to 5.1-channels of digital discrete surround sound.

DTS-HD High Resolution Audio

DTS-HD High Resolution Audio is an improved version of the

conventional DTS, DTS-ES and DTS 96/24 signals formats, compatible

with sampling frequencies of 96 or 48 kHz and up to 7.1-channels

of discrete digital sound. High data bit rate performance provides

high quality sound. This format is fully compatible with conventional

products, including conventional DTS digital surround 5.1-channel

data.

DTS-HD Master Audio

DTS-HD Master Audio is DTS, Inc’s lossless audio format compatible

with up to 96 kHz/7.1-channels. The lossless audio coding technology

faithfully reproduces the sound of the studio master. It is fully

compatible with conventional products, including conventional DTS

digital surround 5.1-channel data.

DTS-ES™ Discrete 6.1

DTS-ES™ Discrete 6.1 is a 6.1-channel discrete digital audio format

adding a surround back (SB) channel to the DTS digital surround sound.

Decoding of conventional 5.1-channel audio signals is also possible

according to the decoder.

DTS-ES™ Matrix 6.1

DTS-ES™ Matrix 6.1 is a 6.1-channel discrete digital audio format

inserting a surround back (SB) channel to the DTS digital surround

sound through matrix encoding. Decoding of conventional 5.1-channel

audio signals is also possible according to the decoder.

DTS 96/24

DTS 96/24 is a digital audio format enabling high sound quality

playback in 5.1-channels with a sampling frequency of 96 kHz and 24

bit quantization on DVD-Video.

Dolby Pro Logic g

Dolby Pro Logic g is a matrix decoding technology developed by Dolby

Laboratories.

Regular music such as that on CDs is encoded into 5-channels to

achieve an excellent surround effect.

The surround channel signals are converted into stereo and full band

signals (with a frequency response of 20 Hz to 20 kHz or greater)

to create a “three-dimensional” sound image offering a rich sense of

presence for all stereo sources.

Home THX Cinema Surround

THX is an exclusive set of standards and technologies established

by the world-renowned ﬁlm production company, Lucasﬁlm Ltd. THX

grew from George Lucas’ personal desire to make your experience of

the ﬁlm soundtrack, in both movie theaters and in your home theater,

as faithful as possible to what the director intended.

Movie soundtracks are mixed in special movie theaters called dubbing

stages and are designed to be played back in movie theaters with similar

equipment and conditions. The soundtrack created for movie theaters

is then transferred directly onto Laserdisc, VHS tape, DVD, etc., and is

not changed for playback in a small home theater environment.

THX engineers developed patented technologies to accurately

translate the sound from the movie theater environment into the

home, correcting the tonal and spatial errors that occur. On the AVC-

A1HD, when the Home THX Cinema mode is on, THX post-processing

is automatically added after the Dolby Pro Logic, Dolby Digital or DTS

decoder:

Re-EQ™ (Re-Equalization)

The tonal balance of a ﬁlm soundtrack will be excessively bright and

harsh when played back over audio equipment in the home because

ﬁlm soundtracks are designed to be played back in large movie

theaters using very different professional equipment. Re-Equalization

restores the correct tonal balance for listening to a movie soundtrack

in a normal home environment.

Dolby Headphone

This is a three-dimensional sound technology developed jointly by

Dolby Laboratories and Lake Technology Ltd. of Australia for achieving

surround sound using regular headphones.

Previously, when using headphones all the sounds resonated inside

the head and it was uncomfortable to listen with headphones for long

periods of time. Dolby Headphone simulates speaker playback in a

room and places the sound at the front or the sides, outside the head,

to achieve a powerful sound like the sound of movie or home theaters.

This technology is mainly for multichannel audio/video equipment with

Dolby Digital or Dolby Pro Logic Surround decoding functions and

works with a high performance digital signal processing (DSP) chip.

Dolby Headphone is effective not only for multichannel sources but

also for stereo programs.

On the AVC-A1HD, it is possible to output signals encoded in the Dolby

Headphone mode from the recording output terminal and record them

on a separate recorder.
