Panasonic DMR-E75V 지침 매뉴얼

This is the digital form of multi-channel audio data (e.g., 5.1 channel) 
before it is decoded into its various channels.

CPRM is technology used to protect broadcasts that are allowed to 
be recorded only once. Such broadcasts can be recorded only with 
CPRM compatible recorders and discs.

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. Dynamic range compression 
means reducing the gap between the loudest and softest sounds. 
This means you can listen at low volumes but still hear dialog clearly.

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 is 24 or 30 frames per second, with motion picture film 

generally being 24 frames per second.

≥Video is 60 fields per second (two fields making up one frame).

A process that makes play of a recorded CD-R, CD-RW, DVD-R etc. 
possible on equipment that can play such media. You can finalize 
DVD-R on this unit.

Formatting is the process of making media such as DVD-RAM 
recordable on recording equipment.
You can format DVD-RAM on this unit. 
Formatting irrevocably erases all recordings on the disc.

Frame refers to the single images that constitute the video you see 
on your TV. Each frame consists of two fields.

≥A frame still shows two fields, so there may be some blurring, but 

picture quality is generally better.

≥A field still shows less picture information so it may be rougher, but 

there is no blurring.

These are uncompressed digital signals. CDs are recorded with 44.1 
kHz/16 bit PCM, while DVDs use PCM between 48 kHz/16 bit and 96 
kHz/24 bit, allowing playback with greater quality sound.
The linear PCM signals output from the DIGITAL AUDIO OUT 
OPTICAL terminal are stereo (2 channel).
LPCM sound is available when recording in XP mode.

An audio compression method that compresses audio to 
approximately one tenth of its size without any considerable loss of 
audio quality. You can play MP3s you have recorded onto CD-R and 
CD-RW.

In general, DVD-Video are produced with the intention that they be 
viewed on a widescreen TV (16:9 aspect ratio), so images often 
don’t fit regular (4:3 aspect ratio) TVs. Two styles of picture, 
“Pan & Scan” and “Letterbox”, deal with this problem.

Pan & Scan:

The sides are cut off so the picture fills the screen.

Letterbox:

Black bands appear at the top and bottom of the 
picture so the picture itself appears in an aspect ratio 
of 16:9.

If a Video CD has playback control, you can select scenes and 
information with menus.
(This unit is compatible with version 2.0 and 1.1.)

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.
Using progressive output, you can enjoy the high-resolution video 
recorded on media such as DVD-Video.
Your TV must be compatible to enjoy progressive video.

You can prevent accidental erasure by setting writing protection or 
erasure protection.

Sampling is the process of converting the heights of sound wave 
(analog 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.

This is a method of video recording that adjusts the bit rate according 
to video signal.

DVD-Video are divided into large sections (titles) and smaller 
sections (chapters). The numbers allocated to these sections are 
called title numbers and chapter numbers.

(1) Title 1
(2) Title 2
(3) Chapter 1
(4) Chapter 2
(5) Chapter 3

This is the smallest division on CD and Video CD.

(1) Track 1
(2) Track 2
(3) Track 3
(4) Track 4
(5) Track 5
