■ Thorough Vibration-resistant Design
Since the high-density data recorded on DVD must be read with absolute
accuracy, vibrations from outside or from internal sources, such as the power
supply, will adversely affect sound and picture quality. A variety of designs
have been incorporated in the DVD-9000 to suppress these unwanted vibrations.
The bottom plate forming the foundation of the chassis is a 6-mm thick, 4-layer
hybrid construction made up of a 1.2-mm thick copper-plated metal sheet
and three layers of 1.6-mm metal sheets. Large insulators of sintered alloy
(the same type used in Denon's high-end S1 series) have been used for the
DVD-9000's feet to absorb external vibrations. Reinforcing plates for the
base, front, and rear are composed of four 1.2-mm thick copper-plated
sheets, that have been utilized in a 3-box construction design to strengthen
the chassis. The chassis also uses copper plating to bring the ground electric
potential of the overall chassis close to equipotential in order to suppress
electrical noise. The top cover uses three types of 1.2-mm thick metal sheets
in different shapes, while 2.5-mm thick aluminum panels have been used for
the sides, giving rigidity to the entire chassis. The DVD mechanism is mounted
on a cast-aluminum base between the mechanism and the chassis. Parts
made of different materials effectively absorb vibrations caused by the unit
itself as well as from outside to ensure stable operation.
■ THX Ultra Certified
The THX Ultra cerification standards are comprised of tests in three categories;
Audio Quality, Video Quality and User Interface. These tests ensure that the
DVD Player is fully capable of bringing out the best visual and sonic quality
of your favorite DVD programs.
■ Newly-Developed Loading Mechanism for Suppression of Vibrations
The newly-developed loading mechanism uses a guide and tray painted with
protein material that is highly resistant to vibrations in order to prevent
unwanted vibrations to the tray.
■ New PureProgressive TM Circuit
The DVD-9000's interlace to progressive converter is the new SiI504
Converter with PureProgressive
TM circuitry from Silicon Image. The SiI504
features faster moving picture detection and improved film/video mode
recognition capability.
High-speed processing: This Sil504 Progressive Converter is capable of
processing 6 billion operations per second, providing the finest in motion-
adaptive de-interlacing.
Moving picture detection: PureProgressive TM features 2:3 pulldown
detection, which converts 24-fps Film based material to 60-fps TV/Video
playback, while also detecting Video based material, animation and graphics.
PureProgressive
TM is capable of reproducing DVD-Video discs containing
both Film and Video material, as well as high picture quality progressive
video sources, while avoiding the flickering caused by detection delays of
these different formats. In processing moving video signals, a conventional
progressive converter performs detection on a full frame-by-frame basis,
while PureProgressive
TM stores 4 fields of video signals in a 64-Mbit SDRAM
buffer, enabling the detection and processing on a pixel-by-pixel basis to
achieve greater precision in discriminating between moving and still pictures.
Improved 2:3 pulldown detection: There are cases in which 2:3 pulldown
data signals on DVD-Video discs are not in sync. The PureProgressive TM
converter will quickly detect the non-sequential points and perform appropriate
corrective measures at high speed to minimize picture flickering.
It is now also possible to select Level Detection or Flag Detection as the
detection method used for Film and Video material. If an incorrect flag was
recorded or the difference between the video level and noise level is very
small and distinctions on the disc are difficult to detect, this selection ensures
optimum detection capability and minimizes picture quality degradation.
■ 14-bit, 108-MHz Video D/A Converter
The DVD-9000 uses a total of six 14-bit, 108-MHz video D/A converters to
tap the maximum potential of the new PureProgressive
TM circuit's performance.
The DVD-9000 uses independent D/A converters for Progressive and
Interlaced picture reproduction.
These converters provide a very high sampling frequency of 108 MHz, with
4x oversampling used for Progressive and 8x oversampling for Interlaced
operation, resulting in the highest detailed D/A conversion. Since a filter with
ample cutoff characteristics can also be used for the analog low-pass filter,
the DVD-9000 reproduces the delicate nuances of video signals, allowing
viewers to enjoy the original picture at the highest level of realism.
Denon engineers have pulled out all the stops in its development of the DVD-9000 to ensure that this DVD player reproduces
sound and pictures at the highest possible level of quality. The DVD-9000 is packed with PureProgressive
TM circuitry for superior
Interlaced-to-Progressive video conversion; six 14-bit, 108-MHz video D/A converters, Noise Shaped Video and a Super Sub
Alias Filter. For high-quality audio output, the DVD-9000 sports AL24 Processing Plus supporting a sampling frequency of 192-kHz;
24-bit, 192-kHz audio D/A converters and other state-of-the-art audio technologies to extract the maximum potential of DVD-
Audio. Along with Denon's critically acclaimed circuit design and chassis construction, the DVD-9000 is a truly remarkable new
flagship DVD player from Denon.
