TENTATIVE

Supports Ultra-High-Quality Progressive Scan Video

The DVD-2800 is endowed with PureProgressive technology to unleash the full impact of DVD-Video picture quality. This DVD video player from DENON is the first to use the Progressive Converter developed by Silicon Image, Inc., ensuring greater accuracy and speed in I/P conversion. The DVD-2800 also uses a 54-MHz, 12-bit video D/A converter to faithfully preserve the delicate low-level signals during D/A conversion. With these advanced video image technologies, the DVD-2800 is able to reproduce high-quality pictures on Progressive-compliant monitors and projectors. The audio circuitry masterfully complements the superior picture quality with its 96-kHz, 24-bit D/A converter, HDCD decoder, and parts strictly selected for high sound quality, providing you with stunning sonic transparency and power.

■PureProgressive Circuit

The DVD-2800 is the first DVD video player to support Silicon Image's Progressive Converter, capable of the highest standard of I/P conversion in the industry.

High-speed processing: This Progressive Converter is capable of processing 6 billion operations per second, giving reality to the following high performance.

Moving picture detection: Since PureProgressive is also adept at 2:3 pulldown detection, which converts Film recording mode to TV/Video play- back mode, and detecting Video mode signals of DVD-Video and other moving picture formats, PureProgressive is capable of reproducing DVD- Video discs containing both Film mode and Video mode signals, as well as high picture quality Progressive video sources, while avoiding the flickering caused by detection delays. In detecting moving video signals, the con- ventional Progressive method performs detection in single frame units, while PureProgressive stores 4 fields of video signals in a 64-Mbit SDRAM buffer, enabling the detection of single-pixel units to achieve greater precision in discriminating between moving and still pictures.

2:3 pulldown detection: In 2:3 pulldown processing which converts

24-fps Film mode into 60-fps TV/Video mode, there are cases in which 2:3 pulldown sync signals are not in sync. The PureProgressive converter thus quickly detects the non-sequential points and performs appropriate corrective measures at high speed to minimize picture flickering.

■Super Sub Alias Filter

The DVD-2800 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

6.25MHz. 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.

■High-performance Output Signal Switching Relay

The DVD-2800 employs a 54-MHz, 12-bit video D/A converter. This video D/A converter performs on Progressive form, and by processing the Y signal and Pb/Pr signals at resolutions of 12 and 11 bits, respectively, PureProgressive is able to faithfully reproduce extremely low-level signals, delivering a delicate yet clear video image.

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