Denon DVD 3930CI

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. 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. 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.
