1 FEATURES
1. Newly developed high performance 10 bit I/P converter
performing all processing with a precision of 10 bits
A high precision film/video source detection function not only
makes the DVD-A1XV compatible with 30 frame film sources,
but also achieves high quality images with smooth, natural
pictures and little jaggy noise even when playing images that
presented problems during editing. In addition, a large number
of picture quality adjustment functions, including noise
reduction and digital gamma correction, enables output of not
only progressive but also HDMI/DVI signals, so fine
adjustments can be made according to the display you are
using.
2. Newly developed 10-bit scaler for high definition pixel
conversion
The DVD-A1XV is equipped with a newly developed scaler that
uses an original algorithm to conduct pixel conversion of the
video output signals which have been given optimum
progressive processing with the I/P converter into higher
definition 720P or 1080i signals with 10-bit precision. This in
conjunction with the high performance 10-bit I/P converter
makes for effective high picture quality playback, and enables
output for digital signals via the HDMI/DVI connectors without
reduction in picture quality due to analog conversion.
In addition, the signals are optimized for output to the
independent HDMI and DVI transmitters, so two digital video
signals can be output at the same time.
3. DPI (DENON Pixel Image) correction function for more
natural outline correction
DENON has developed an outline correction circuit using a
new algorithm that samples the image data of pixels adjacent
to the perceived pixels and processes them. The image is
detected and processed in units of pixels in the vertical,
horizontal and diagonal directions, thereby generating more
natural outlines.
In addition, other processing is performed in ways optimum for
the images, for example brightness signals and color signals
are processed with independent algorithms, ringing that tends
to occur when images are enhanced is restrained, etc.,
thereby achieving more natural images with no reduction in
picture quality.
4. 14-bit/216 MHz video D/A converter (NOTE 1)
The DVD-A1XV uses a video D/A converter that conducts D/A
conversion of all video signals at 14 bits and allows 8X
oversampling in the progressive mode to achieve the high
quality picture that DVDs are meant to provide. In addition,
NSV technology reduces noise upon D/A conversion.
5. HDMI/DVI digital video interface (NOTE 2)
HDMI Ver. 1.1 enables digital transfer of the video and audio
signals of DVD audio discs that are copyright-protected by
CPPM, something that was not possible with HDMI Ver. 1.0.
The DVD-A1XV is HDMI Ver. 1.1 compatible.
(1) HDMI connector
Digital video signals are transferred in Y Cb Cr or RGB.
The audio signals can be transferred simultaneously, so
both audio and video signals can be transferred with a
single cable.
(2) DVI-D connector
Digital video signals are transferred in RGB.
6. Advanced AL24 Processing
“Advanced AL24 Processing” which greatly increases the
amount of information in the time axis area using unique high
speed signal detection and processing technology for the PCM
signal (CD/DVD) playback circuitry is provided for 2-channel
output. In addition to expansion of data to 24 bits, natural
signal correction without marring the original data is performed
with upconversion sampling.
In addition, DENON’s original analog waveform reproduction
technology, “AL24 Processing PLUS”, is used for the 5.1-
channel audio output, resulting in high sound quality for all
PCM signal sources.
7. High precision 24-bit D/A converter
The audio playback circuit includes an advanced segment type
D/A converter with the high technical specifications in the
business, manufactured by Burr-Brown, a company with an
established reputation for D/A converters. This high
performance D/A converter allows not only input of the 24-
bit/192 kHz data of DVD-Audio discs, it also includes an analog
pure FIR filter for ideal DSD playback of Super Audio CDs.
Furthermore, for mixed left and right channel signals, this D/A
converter is used for independent monaural modes for both
the left and right channels, a true luxury enabling playback of
even high quality signals.
8. DENON LINK/IEEE1394 digital audio transfer connectors
Digital transfer is possible not only of the audio of DVD video
discs but also of the multi-channel audio of DVD audio discs
and Super Audio CDs.

(2) IEEE 1394 terminal
9. THX® Ultra Certification, the symbol of excellent high
quality (NOTE 3)
The DVD-A1XV meets THX® Ultra standards, a strict set of
criteria advocated by Lucasfilm on the picture and sound
quality of DVD video players and their operability with
connected equipment. This makes it possible to achieve the
high quality pictures and sound.
