Glossary
Bitstream
This is the compressed form of digital signals. A decoder decodes 
these signals into 5.1 surround and multi-channel signals.
Channel (when referring to DVD)
Sound is divided into channels based on the sound’s role.
For 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 channelk0.1 (the ratio of bass to the total amount 
of sound output)
Examples as shown in the status display
(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
2: Front leftiFront right
3: Front leftiFront rightiCenter
DIRECT NAVIGATOR
This is a list of programmes you have recorded. You can select 
programmes from the list to view. The list also shows the date and 
time of recording, the channel, and the titles of titled programmes. 
The selected programme is played in the background, making 
selection even simpler.
Dolby Digital
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.
Dolby Pro Logic
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.
DTS Digital Surround
This surround system is used in many movie theaters around the 
world. The separation between channels is good and the 
compression ratio is low, so realistic sound effects are possible.
DTS soundtracks are produced with the assumption that all 
channels will be used.
Finalize
This process allows DVD-R to be played on compatible equipment.
Frame and field
Frames are the still pictures that go together to make a moving 
picture. A frame is made up of 2 fields.
Frame
  
Field
 
    
Field
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.
Linear PCM
This is a form of signal that has been digitized without compressing 
it. 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 
reproduction of greater quality sound.
The linear PCM signals output from the DIGITAL AUDIO OUT, 
OPTICAL terminal are stereo (2 channel).
NICAM
 (NICAM Broadcasting System)
This is a 2 channel sound broadcast system which in most 
instances provides high quality stereo sound. Broadcasters can 
also transmit two separate mono soundtracks on this system.
Pan&Scan/Letterbox
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.
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.
Playback control (PBC)
This is a method of playing Video CDs. You can select parts to 
play by using menus recorded on the disc.
PLAY LIST
This is a collection of scenes. It enables you to play these scenes 
in succession or to select specific ones to play.
Programme (PRG)
The section between the point where recording is started and the 
point where it is stopped.
Sampling frequency
This is the number of samples of sound taken per second during 
conversion to a digital signal. A high sampling frequency results in 
a sound close to the original when played back.
S-video output
The colour and luminance signals are separated before being sent 
to the television, making for greater picture clarity.
