Panasonic pv-dr2714 Operating Guide

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.

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 multichannel 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. The surround 

channel is monaural and can reproduce up to 7 kHz.

This is the process of remixing the multi-channel audio found on 

some discs into two channels for stereo output. It is useful when 

you want to listen to the 5.1-channel audio recorded on DVDs 

through your television’s speakers. Some discs prohibit down-

mixing and this unit can then only output the front two channels.

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. 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 or DVD-R 

etc. possible on equipment that can play such media. You can 

finalize DVD-R on this unit.

You cannot record onto or edit finalized discs.

Formatting is the process of making media such as DVD-RAM 

recordable on recording equipment. You can format the DVD-RAM 

on this unit. Formatting erases irrevocably all recordings on the 

disc.

Frames refer to the single images that constitute the video you see 

on your television. 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. This unit outputs linear 

PCM sound in 2 channels from the DIGITAL AUDIO OUT terminal.

An audio compression method that compresses audio to 

approximately one tenth of its size without any considerable loss of 

audio quality. You can play MP3 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 television with an aspect ratio of 16:9. This 

means you can view most material with the intended aspect ratio 

on a widescreen television. Material with this ratio will not fit onto a 

standard television with an aspect ratio of 4:3. Two styles of picture, 

“Pan&Scan” and “Letterbox”, deal with this problem.

The sides are cut off so the picture fills the 

screen.

Black bands appear at the top and bottom of 

the picture so the picture itself appears in an 

aspect ratio of 16:9.

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.

Written dialogue which appears at the bottom of the screen.

This is a method of video recording that adjusts the bit rate 

according to video signal.
