Terminology

Dolby Digital

Dolby Digital is a digital audio compres-

sion technology developed by Dolby

Laboratories that allows large quantities of

audio data to be efficiently recorded on

discs. It is compatible with audio signals

from mono (1 channel) all the way up to

5.1-channel surround sound. The signals

for the different channels are completely

independent, and since the sound is high

quality digital there is no loss of sound

quality.

* The separately sold digital audio

processor (PXA-H510) is required to

enjoy full 5.1-channel surround sound.

The DVA-5205E performs Dolby Digital

decoding when it outputs analog audio

signals, it just happens to be 2-channel

audio not 5.1-channel.

DTS

This is a home-use digital sound format of

the DTS Sound System. This is a high

quality sound system, developed by

Digital Theater Systems Corp for use in

movie theaters.

DTS has six independent sound tracks.

The theater presentation is fully realized

in the home and other settings. DTS is

the abbreviation for Digital Theater

System.

* To enjoy DTS surround sound you need

the separately sold DTS digital audio

processor. The DVD video software

must also have a DTS sound track.

Dolby Pro Logic

Dolby Pro Logic is the technology used to

decode programs encoded in Dolby

Surround. Pro logic decoding will provide

you with four channels of sound (front left/

right, center and monaural rear surround)

from a 2-channel (stereo) source.

* The separately sold digital audio

processor (PXA-H510) is required to

enjoy Dolby Pro Logic surround sound.

Linear PCM audio (LPCM)

LPCM is a signal recording format used

for music CDs. Whereas music CDs are

recorded at 44.1 kHz/16 bits, DVDs are

recorded at 48 kHz/16 bits to 96 kHz/24

bits, thereby achieving higher sound

quality than music CDs.

Rating levels (parental lock)

This is a function of the DVD for restricting

the viewing age as stipulated by laws in

different countries. The way in which

viewing is restricted differs from DVD to

DVD. Sometimes the DVD cannot be

played at all, other times certain scenes

are skipped, and other times certain

scenes are replaced with other scenes.
