DVD-2900

DVD Audio/Video & Super Audio CD Player

The DVD-2900 is endowed with PureProgressive

technology to unleash the full impact of DVD-Video picture

quality. The DVD-2900 also uses a 12-bit, 108-MHz video D/A converter to faithfully preserve the delicate low-level

signals often lost during D/A conversion. With these advanced video image technologies, the DVD-2900 will reproduce

with the highest resolution, DVD images on Progressive-compliant monitors and projectors. For sound, it is high

quality audio D/A conversion and Digital Bass Management that will bring out the best of not only Super Audio CD

and DVD-Audio discs, but your entire CD collection as well.

Super Audio CD

DENON supports Super Audio CD, the new-generation media format, with the

DVD-2900.

Super Audio CD is recorded using the DSD (Direct Stream Digital) method,

based on a concept that differs from PCM. Since DSD records signal output

from the Delta-Sigma modulator as is, it is recorded as the compressional wave

of a 1-bit pulse signal at the sampling rate of 2.8224 MHz.

The DSD format has a dynamic range of 120 dB (the audible band) and covers

a playback frequency that extends to as much as 100 kHz, enabling playback

that is extremely close to the original waveform. DSD is capable of recording all

sound that exists in the natural world. To bring out the maximum potential of

this sonic experience, the DVD-2900 incorporates a dedicated DSD decorder

for Super Audio CD playback. The DVD-2900 supports Super Audio CD multi-

channel discs capable of recording up to 6 channels of data at full specifica-

tions. It also supports Single Layer, Dual Layer, and Hybrid Layer discs.

New PureProgressive™ Circuit

The DVD-2900's interlace to progressive converter is the new SiI504 Converter

with PureProgressive™ 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-adap-

tive de-interlacing.

Moving picture detection: PureProgressive™ features 2:3 pulldown detec-

tion, which converts 24-fps Film based material to 60-fps TV/Video playback,

while also detecting Video based material, animation and graphics.

PureProgressive™ 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 differ-

ent formats. In processing moving video signals, a conventional progressive

converter performs detection on a full frame-by-frame basis, while

PureProgressive™ 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™ converter will quickly detect the non-sequential points

and perform appropriate corrective measures at high speed to minimize picture flick-

ering.

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.

■ 12-bit, 108-MHz Video D/A Converter

An extremely high-speed video D/A converter is a critical component in superior

quality digital video playback. The DVD-2900 therefore uses a 12-bit, 108-MHz

video D/A converter to ensure highly accurate playback of delicate, low-level

video signals and give you a vivid picture that is faithful in every detail.

Oversampling of 4x is used for both Progressive and Interlaced video signals,

allowing more detailed D/A conversion. Higher quality picture reproduction is

also possible thanks to a filter with flexible shutout characteristics that is used

for the analog filter in the latter stage. Furthermore, the DVD-2900 uses two

separate video D/A converters to process Progressive and Interlaced signals.

This eliminates mutual interference between the Progressive and Interlaced

signals.

■

Noise Shaped Video (NSV)

The NSV feature works in the digital domain to reduce noise in the video signal fre-

quency band in order to enhance video signal linearity.

■

Super Sub Alias Filter

The S/N ratio can be improved when unwanted signals of higher than 6.75

MHz following D/A conversion are cut. The DVD-2900 thus uses a Super Sub

Alias Filter that produces flat characteristics, ensuring that adverse influences

do not affect video signals inside the essential frequency band, and folding noise

is eliminated. In the DVD-2900, the Super Sub Alias Filter is applied to the chro-

ma signal as well as the luminance signal, improving color reproduction.

■

Thorough Vibration-resistant Design

Since the high-density data recorded on DVD must be read with absolute accu-

racy, vibrations from outside or from internal sources, such as the power sup-

ply, will adversely affect sound and picture quality. A variety of designs have

been incorporated in the DVD-2900 to suppress these unwanted vibrations:

• The DVD mechanism section in the main chassis has been divided in a two-

box construction to further protect it from vibrations.

■

Burr-Brown 24-bit, 192-kHz Audio D/A Converter

The DVD-2900 uses a 24-bit, 192-kHz audio D/A converter that is well protected

from noise caused by fluctuations in current from the power supply. Since the level

of quantization noise within the frequency range is uniform for all frequencies, this

D/A converter ensures that all the sound you hear is as clear and noise-free as

possible.
