Panasonic ag-vp300 User Manual

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: 3/2 .1ch

.1: Subwoofer signal 

(not displayed if there is no subwoofer signal)

 1:  Mono surround
 2:  Stereo surround (left/right)

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

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

This is a method of coding digital signals developed by Dolby 
Laboratories. Apart from stereo (2-channel) audio, these signals 
can also be 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.

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.

To process a DVD-R, CD-R or CD-RW disc recorded on by DVD 
recorder, etc. so that it can be played back by a player.

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 overall quality is high.

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

frame still so picture quality is lower.

An MP3 file 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.

NTSC, the video signal standard, has 480 interlaced (I) scan lines, 
whereas progressive scanning uses twice the number of scan 
lines. This is called 480P. To output progressive video, connect the 
Component video out terminal on the rear panel of this unit to the 
component video input terminals and press [PROGRESSIVE 
OUT] so that “PR ON” appears. You can enjoy video quality higher 
than that of the conventional VIDEO OUT or S-VIDEO OUT 
terminals.

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.
This unit outputs linear PCM signals fed from the OPTICAL 
DIGITAL AUDIO OUT terminal with 2 channels.
