Panasonic NVVP60SERIES Guia De Utilização

Sound is divided into channels based on the sound’s role.
Example: 5.1 channel
≥Front speakers— 1 left channel and 1 right channel
≥Center speaker— 1 channel
≥Surround speakers— 1 left channel and 1 right channel
≥Subwoofer— 1 channel a0.1

 

(the ratio of bass to the total amount 

of sound output)

The following are indicated on the On-Screen Menu Icons.

Example:

(1) .1: Subwoofer signal 

(not displayed if there is no subwoofer signal)

(2)  0: No surround
 

 1: Mono surround

 

 2: Stereo surround (left/right)

(3)  1: Center

Digitized and compressed audio signal.
It is decoded by decoders into multi-channel audio signals, such as 
5.1 channels.

This device restores the coded audio signals on DVDs to normal. 
This is called decoding.

DivX is a popular media technology created by DivX, Inc. DivX media 
files contain highly compressed video with high visual quality that 
maintains a relatively small file size.

This is a method of coding digital signals developed by Dolby 
Laboratories. Apart from stereo (2-channel) audio, these signals are 
also compatible with 5.1-channel audio. A large amount of audio 
information can be recorded on one disc using this method.

A surround system where a 4-channel audio track is recorded as 2 
channels and then is restored to 4 channels for play. 

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.

DVD-Videos are recorded using either film or video. This unit can 
determine which type has been used, then uses the most suitable 
method of progressive output.

Film:

Recorded at 25 frames per second (PAL discs) or 24 frames 
per second (NTSC discs). (NTSC discs recorded at 30 
frames per second as well). Generally appropriate for motion 
picture films.

Video: Recorded at 25 frames/50 fields per second (PAL discs) or 

30 frames/60 fields per second (NTSC discs). Generally 
appropriate for TV drama programs or animation.

Frames are the still pictures that go together to make a moving 
picture. A frame is made up of 2 fields.

≥A frame still is made up of two alternating fields so the picture may 

appear blurred but the overall quality is high.

≥A field still is not blur, but it has only half the information of a frame 

still so picture quality is lower.

MP3 file that has an area in which the character-based information 
referred to as ID3 tag, is stored. The information of the track, such as 
the title, artist name, etc. can be stored here. The information can be 
displayed on players supporting the ID3 tag when a track is played 
back. However, this unit cannot because it does not support the ID3 
tag.

The NTSC video signal standard has 480 interlaced (i) scan lines, 
whereas progressive scanning uses twice the number of scan lines. 
This is called 480p.

The DVD recording system shares the data commonly used by 
screens and uses screen-independent data individually for each 
screen to store the data on the disc efficiently.

≥I-picture (Intra coded picture):

A frame recorded independently as reference for commonly used 
data.

≥P-picture (Predictive coded picture):

This picture is calculated based on past I- or P-pictures.

≥B-picture (Bidirectionally-predictive coded picture):

This picture is calculated by comparing past and future I- and 
P-pictures so it has the lowest volume of information.

I-picture has the best quality and is the best to use when adjusting 
the picture.

These are uncompressed digital signals, similar to those found on 
CDs.

An audio compression method that compresses audio to 
approximately one-tenth of its size without any considerable loss of 
audio quality. 

A compression system for use on mobile devices or a network, that 
allows highly efficient recording at a low bit rate. Recorded with the 
Panasonic SD multi cameras or DVD recorders and plays.

≥This means recording data onto a CD-R/RW disc several times. 

“Read-in/Programme area/Read-out” of the data on a disc makes 
one session.

≥If data, such as music, is added onto a pre-recorded CD-R/RW 

disc, a new session will be added. Such a disc is referred to as a 
multisession disc.

≥Normal audio CD players can playback only the first session. On 

the other hand, this unit can playback 2 or more sessions.

≥If a Video CD has playback control, you can select scenes and 

information with menus.

≥In this manual, playing back of the contents of a Video CD using 

the menu screen is referred to as “Menu play” for Video CD.

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 more faithful reproduction of the 
original sound.

WMA is a compression format developed by Microsoft Corporation. 
It achieves the same sound quality as MP3 with a file size that is 
smaller than that of MP3.
