Recording to digital recording equipment or cassette tapes
≥Digital recording
You can record the digital signal directly to digital recording equipment.
Connect the recording equipment with an optical fiber cable (➡ [A] page 34).
Note
≥With DVD, the following conditions must be met: a the disc doesn’t have protection preventing
digital recording, and b the recording equipment can handle signals with a sampling frequency of
48 kHz.
≥You cannot record WMA/MP3.
When recording DVDs, make the following settings.
Advanced Surround: OFF (➡ page 25)
PCM Down Conversion: Yes (➡ page 32)
Dolby Digital/DTS Digital Surround: PCM (➡ page 33)
≥Analog recording
You can record to a cassette deck or other recording equipment. There are no limitations on
recording analog signals as there are with digital signals.
Connect the recording equipment with the stereo connection cable (➡ [B] page 34).
Bitstream
The digital form of multi-channel data (e.g.,
5.1 channel) before decoding.
Decoder
A decoder restores the coded audio signals on
DVDs to normal. This is called decoding.
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 multi-channel audio. A large amount of audio
information can be recorded on the 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 and can reproduce up to
7 kHz.
DTS (Digital Theater Systems)
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
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.
Frame still and field still
Frames are the still pictures that make moving
pictures. About thirty are shown each second. A
frame still may appear blurred but overall quality
is high.
Two fields appear alternately to make up one
frame. A field still is not blurred but picture
quality is lower.
I/P/B
MPEG 2, the video compression standard
adopted for use with DVD-Video, codes frames
using these 3 picture types.
I: Intra coded picture
This picture has the best quality and is the
best to use when adjusting the picture.
P: Predictive coded picture
This picture is calculated based on past I or
P-pictures.
B: 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.
Linear PCM (pulse code modulation)
These are uncompressed digital signals, similar
to those found on CDs.
Playback control (PBC)
If a Video CD has playback control, you can
select scenes and information with menus.
Glossary
Enjoying more powerful sound
Enjoy the powerful movie theater and hall-like sound available with multiple channel audio found on
DVDs by connecting an amplifier and speakers.
Note
≥The equipment connections described are examples.
≥Peripheral equipment and optional cables sold separately unless otherwise indicated.
≥Before connection, turn off all equipment and read the appropriate operating instructions.
Using this unit with other equipment
To enjoy stereo or Dolby Pro Logic
Connect a digital amplifier or system component.
