With the DTS-ES Discrete 6.1 format, all 6.1 channels, including the surround back

(SB) channel, are recorded independently using a digital discrete system. The main

feature of this format is that because the SL, SR and SB channels are fully

independent, the sound can be designed with total freedom and it is possible to

achieve a sense that the acoustic images are moving about freely among the

background sounds surrounding the listener from 360 degrees. Though maximum

performance is achieved when sound tracks recorded with this system are played

using a DTS-ES decoder, when played with a conventional DTS decoder the SB

channel signals are automatically down-mixed to the SL and SR channels, so none of

the signal components are lost.

With this format, the additional SB channel signals undergo matrix encoding and are

input to the SL and SR channels beforehand. Upon playback, they are decoded to the

SL, SR and SB channels. The performance of the encoder used at the time of

recording can be fully matched using a high precision digital matrix decoder

developed by DTS, thereby achieving surround sound more faithful to the producer's

sound design aims than with conventional 5.1- or 6.1-channel systems. In addition,

the bit stream format is 100% compatible with conventional DTS signals, so the

effect of the Matrix 6.1 format can be achieved even with 5.1-channel signal sources.

When DTS-ES Discrete 6.1 or Matrix 6.1 encoded sources are decoded with a DTS-

ES decoder, the format is automatically detected upon decoding and the optimum

playing mode is selected. However, some Matrix 6.1 sources may be detected as

having a 5.1-channel format, so the DTS-ES Matrix 6.1 mode must be set manually

to play these sources.

This mode is optimum for playing movies. Decoding is performed with emphasis on

separation performance to achieve the same atmosphere with 2-channel sources as

with 6.1-channel sources.

This mode is effective for playing sources recorded in conventional surround formats

as well, because the in-phase component is assigned mainly to the center channel and

the reversed phase component to the surround (left, right, and back) channels.

This mode is suited mainly for playing music. The front (left and right) channel

signals bypass the decoder and are played directly, so there is no loss of sound

quality, and the effect of the surround signals output from the center and the

surround (left, right, and back) channels add a natural sense of expansion to the

sound field.

This mode is used to play stereo source material in its pure unprocessed form.

In 5.1, 6.1, and 7.1 surround formats, the point 1 represents an extra channel for LFE

sounds (120 Hz and below) that is decoded and routed to a subwoofer (if present).

The LFE channel signal is added to any other low frequency signals routed to the

subwoofer from channels unable to produce effective low frequency sound.
