■ I/P converter from Silicon Optix, Inc.
The DVD-3930CI uses the 10-bit I/P converter “REALTA” developed through a
joint development effort that merged image processing algorithms of Silicon Optix,
Inc., and Denon video technology on the foundation of an image processing
device from Teranex, a manufacturer of video processing for broadcast use in the
United States. This 10-bit processing offers high conversion performance and dra-
matically improves motion detection capability. Regularity in pixel-level patterns are
rapidly and accurately detected not only in the 3:2 patterns of film sources but in
other patterns as well during I/P (Interlaced/Progressive) conversion. Even when
sources contain both Video mode and Film mode material, each mode is detected
and processed accurately at high speed. Flicker caused by detection delays is
avoided, and Progressive playback with high picture quality is
possible from a variety of discs. In addition, Multi-Directional
Diagonal Filter (MDDF) technology, used for the first time in the
DVD-5910CI, which accurately detects and corrects the direc-
tionality of lines on a per-pixel level to avoid "jaggies" that easi-
ly appear when video sources are I/P converted, ensuring
smooth picture playback.
■ Denon Pixel Image Correction, for more natural contour correction
The Denon Pixel Image Correction feature that incorporates original Denon
enhancement technology and makes high-definition video correction possible,
has been advanced to even greater heights in the DVD-3930CI. Denon Pixel
Image Correction performs detection and correction through 10-bit processing
to significantly improve contour correction. This new contour correction circuit
uses enhancement processing technology that also considers the influence of
pixels surrounding the target pixels. It uses new algorithms to sample and analyze
a total of 9 pixels of video data around, and including, each target pixel. Video
images are detected and processed in vertical, horizontal, and diagonal directions
at a highly detailed per-pixel level to produce contours that are visually more
natural. Luminance and chroma signals are also processed with the same
algorithms to suppress ringing noise and other artifacts that easily occur during
enhancement. By performing the type of processing that is most effective for the
current video image, the picture is free of degradation and appears more natural.
■ High-performance video scaler capable of 1080p output for HDMI
“REALTA”also works as the high-performance video scaler in the DVD-3930CI.
This high-precision 10-bit scaler works with HDMI digital video output signals. This
scaler executes optimum conversion to suit the output. Users can enjoy the best
picture quality for their particular applications. Also this scaler can output PC reso-
lution VGA/XGA/WXGA and SXGA signals.
■ Dual Discrete Video Circuit (DDVC)
The DVD-3930CI's video circuit features Denon's own DDVC technology
designed to enhance the quality of video signals. The use of dedicated circuits
–one independent block for composite and S-video signals, another block for
component signals, and a dual DAC configuration with built-in video encoder –
has made it possible to reproduce detailed video images with greater precision. In
order to bring out the maximum quality from both video and audio signals, the
DVD-3930CI has a discrete configuration in which the video, audio, and digital
blocks that comprise this universal player are all completely isolated from each
another in terms of their circuit configuration, boards, and power supplies. Denon
engineers have used the expertise gained from their development of earlier universal
players to design a configuration that thoroughly suppresses mutual interference
among the circuits and prevents noise from affecting the video and audio signals.
■ High-speed, high-precision 14-bit 216-MHz video DAC
To ensure that high-grade video signals from the latest high-performance I/P con-
verter are reproduced with utmost fidelity to the original images, the DVD-3930CI
has an extremely fast and accurate 14-bit, 216-MHz video DAC. Oversampling of
8x for Progressive and 16x for Interlaced signals results in sharp, detailed pic-
tures. Composite, S-video and component signals each have their own dedicated
video DAC, a design that enhances the reproduction of low-level video signals
and reproduces high-definition images that are faithful to the original. In addition,
Noise Shaped Video (NSV) technology is used to improve the S/N of video signals
and further boost their linearity.
■ Keystone
DVD3930CI can adjust keystone, +/- 30 degree for Vertical and +/- 40 degree for
Horizontal for front projector.
■ Supports fine picture quality adjustments
Besides the DPIC feature, a total of 15 picture quality adjustments are possible,
including contrast, sharpness, white level, chroma level, noise reduction settings,
and gamma. Up to five combinations of settings can also be stored in memory,
giving the user freedom to adjust picture quality in considerable detail according
to individual preferences.
■ Custom Integrated
• RS232C serial command control
• Remote in/out IR command control
• Discrete Power on/off command
• 480i output capable for HDMI
*1) Version 1.1 compliant. HDMI audio output capacity is dependent on the monitor being used.
*2) HDMI output is HDCP compliant. Video cannot be viewed if connected to a monitor that does not support HDCP;
video can be viewed only on HDCP-compliant monitors.
*3) HDMI 1080p output is 50/60 Hz refresh rate only.
