Denon dvd-2800mk.ii 产品宣传册

The DVD-2800MK2 is endowed with a new PureProgressive

TM

circuit to give you even greater fidelity in picture

playback than the critically acclaimed PureProgressive

TM

technology of the DVD-2800. High-quality picture

playback is also ensured by the DVD-2800MK2's high-accuracy 12-bit, 108-MHz video D/A converter, Super

Sub Alias Filter, Noise Shaped Video (NSV) and other features. High-quality sound with a superior dynamic

range, S/N ratio and stunning transparency has been made possible with the DVD-2800MK2's 24-bit, 96-kHz

audio D/A converter as well as a highly rigid vibration-resistant chassis, hybrid loader mechanism and other

technologies that preserve the extremely high quality sound from sources like DVD.

The DVD-2800MK2'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.

Since a high-speed video D/A converter is indispensable to superior
quality digital video playback, the DVD-2800MK2 uses a 12-bit, 
108-MHz video D/A converter that ensures highly accurate playback
of delicate, low-level video signals to give you a vivid picture that is
faithful in every detail. A filter with flexible shutout characteristics that
is used for the analog filter in the latter stage further contributes to
high-quality picture reproduction. The DVD-2800MK2 also uses two
separate video D/A converters to process Progressive and Interlaced
signals, effectively eliminating mutual interference between these two
types of signals.

When interlaced video is detected, DVD-2800MK2 uses the 27-MHz,
10-bit video D/A converter, so that with either video format, delicate
nuances are D/A converted with optimum accuracy.

The NSV feature works in the digital domain to reduce noise in the video
signal frequency band in order to enhance video signal linearity.

■

The DVD-2800MK2 uses a Super Sub Alias Filter for the digital filter to
optimize picture quality. This filter achieves attenuation characteristics
of -3 dB in the ultra-high frequency band when the horizontal image is
6.25 MHz. Even at 8.25 MHz, the apparent outer limit of DVD-Video,
the attentuation characteristic secured is above -60 dB, ensuring an
ultra-high picture quality with superior horizontal line resolution.

■

The DVD-2800MK2 is equipped with 1 set of Component video 
outputs for both Progressive signal (Y, Pb, Pr) and Interlaced signal
(Y, Cb, Cr) output. Wideband relay switching is employed when
switching between Progressive and Interlaced Output, for optimum 
picture quality in either mode.
