Analogue

Audio signals produced from L/R audio output

terminals of general equipment is called analogue

audio.

Surround signal

Audio signal made up of front speakers, center

speaker and surround speakers. For this unit,

surround signal is automatically played by Dolby

Virtual Speaker.

Sampling frequency

Sampling is the process of converting the heights of

sound wave (analogue signal) samples taken at set

periods into digits (digital encoding).

Sampling frequency is the number of samples

taken per second, so larger numbers mean faithful

reproduction of the original sound.

HDMI Standby mode

When this unit and TV (VIERA) and DIGA DVD

recorder are connected with HDMI cables, image/

audio from DIGA can still be transmitted to TV even

though the unit is turned off.

This is useful when you want to enjoy late night

viewing only with the television’s speakers.

Dynamic range

Dynamic range is the difference between the lowest

level of sound that can be heard above the noise of

the equipment and the highest level of sound before

distortion occurs.

Decoder, Decode

Decoder is the device to enable us to hear audio

data that is encoded on DVD, etc., as a normal

audio signal. This process is called decoding.

Digital

Blu-ray Disc players, DVD recorders, DVD players,

and CD players are usually equipped with digital

output terminals. Connect through the digital

terminal to enjoy digital surround systems such as

Dolby Digital and DTS.

Dolby Surround

Dolby Surround is a four-channel analogue

surround system, consisting of two front channels

(left and right) (stereo), a center channel for

dialogue (monaural), and a surround effect channel

(monaural), producing a dynamic and rich surround

effect. The surround channel plays a narrow range.

Optical

Using optical fibre cable for digital signal input/

output from DVD, CD, etc., provides better sound

quality for playback or recording compared to

analogue. Only possible with equipment that has an

optical terminal.

CPPM (Content Protection for Prerecorded Media)

This is the copyright protection technology which

prevents file copy of DVD audio.

Dolby Digital (DVD etc.)

Digital surround system developed by Dolby

Laboratories.

Dolby Pro Logic ΙΙ

This system can process not only Dolby Surround,

but also other 2-channel sources to produce a 5.1-

channel sound for a more realistic sound field. It is

also possible to enhance old movies recorded in

stereo with this dynamic 5.1-channel sound. This

unit uses Dolby Pro Logic ΙΙ to add surround effects

to stereo sources such as video cassettes and CDs.

Dolby Virtual Speaker

This system allows you to enjoy a surround effect with

two front speakers, a center speaker, and a subwoofer.

This is not merely a “virtual surround” effect, but rather

uses the optimal speaker arrangements and listening

positions for 5.1-channel sound.

DTS (Digital Theater Systems)

Digital surround system developed by DTS, Inc.

This surround system is used in many movie

theaters around the world. There is good separation

between the channels, so realistic sound effects are

possible.

HDMI (High Definition Multimedia Interface)

HDMI is a next-generation digital interface for

consumer electronic products. Unlike conventional

connections, it transmits uncompressed digital

video and audio signals on a single cable. This

unit supports high-definition video output (720p,

1080i) from the HDMI AV OUT terminal. To enjoy

high-definition video, a high-definition compatible

television is required.

PCM signal (CD, DVD audio, etc.)

Analogue sounds are converted to a digital

bitstream signal. This is the type of digital audio

signal used for CD, DVD audio, etc.

5.1 Channel surround

Monaural and stereo use one channel and two

channels respectively to reproduce sound, but

5.1-channel surround uses 5 speakers and a

low frequency effect channel. The 5 channels

are: 1 center speaker, 2 front speakers, and 2

surround speakers at the side of or to the rear of

the sitting position. Sound output of the subwoofer

is much narrower than the other speakers, and so

is considered as 0.1. This is called 5.1-channel

surround when played through all 5.1 channels, and

with this unit you can achieve a similar effect with

Dolby Virtual Speaker.
