Matrix 6.1
The unit incorporates Matrix 6.1 decoder for Dolby
Digital and DTS multi-channel software that enables 6.1-
channel reproduction by adding the rear center channel to
existing 5.1-channel format. (The rear center channel is
created from rear left and right channels, and outputted
from virtual rear center speaker.) With this additional
channel, you can experience more dynamic and realistic
moving sound especially with scenes with “fly-over” and
“fly-around” effects.
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention
that they are 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)
If a Video CD has “playback control” written on it or its
jacket, it means that particular scenes or information can
be selected for viewing interactively with the television
using the menu screen. This unit can play Video CDs with
playback control.
Using menus to control play of a Video CD is called
“menu play” in these operating instructions.
Sampling frequency and number of
quantized bits
When digitizing an analog audio signal, the number of
times the signal is sampled per second is called the
sampling frequency, while the degree of fineness when
converting the sound level into a numeric value is called
the number of quantized bits.
Interlace and progressive output
NTSC, the video signal standard, has 525 interlaced (i)
scan lines, whereas progressive scanning uses twice the
number of scan lines.
This is called 525p. The 525i video signals output from
this unit’s COMPONENT VIDEO OUT terminals (Y, P

) allow you to enjoy higher quality pictures than
if the signals were output from the video output terminal
or S VIDEO OUT terminal. The COMPONENT
VIDEO OUT terminals are also able to handle 525p
(progressive) video signals which are of even greater
resolution.
I/P/B
MPEG, the video compression standard adopted for use
with DVD-Video, codes frames using these 3 picture
types.
I: Intra coded picture (I-picture)
This is the standard picture and is a complete picture
in itself.
This means it has the best picture quality and is the
best to use when adjusting the picture.
P: Predictive coded picture (P-picture)
This picture is calculated based on past I or P-
pictures.
B: Bidirectionally-predictive coded picture (B-picture)
This picture is calculated by comparing past and
future I and P-pictures so it has the lowest volume of
information.
LFE 0.1 channel
This channel is for the reproduction of low bass signals.
The frequency range for this channel is 20 Hz to 120 Hz.
This channel is counted as 0.1 because it only enforces a
low frequency range compared to the full-range
reproduced by the other 5 channels in a Dolby Digital or
DTS 5.1 channel systems.
Linear PCM (pulse code modulation)
PCM is the usual digital method used for music CDs.
DVDs have a greater volume so they use linear PCM,
which has a higher sampling rate. Compressed PCM
signals are called packed PCM (PPCM).
