Digital Recording

With an extremely mild, perceptually lossless 3:3:1 compression ratio and a data rate of 50 Mbps, D-9 can capture even the most challenging picture in all its splendor without compression artifacts such as pixel noise, edge defects, blockiness and multi-generation degradation produced when 5:1 compression systems record difficult pictures. D-9's low compression intra-frame processing ensures beautiful high resolution pictures when cascading compression CODEC’s such as MPEG-2 mastering for DVD.

Highly efficient 50 Mbps intra-frame encoding has emerged as the standard reference for mainstream television production. To maintain superb picture quality from acquisition to production, all D-9 products use a data rate of 50 Mbps.

In 1998, a joint SMPTE/EBU task force test results show that D-9 provides;

Quality identical to that produced by Digital Betacam

Superior quality to that found in Beta-SP

Better quality to 50 Mbps MPEG-2 1 frame only compression

Heavy-duty Tape Transport Mechanism with Die-cast Magnesium Chassis

The heavy-duty tape transport system of the DY-70U ensures high-quality pictures. Moreover, a die-cast magnesium chassis ensures durable, rigid support for both mechanism and electronics, while its integrated drum base improves linearity.

14-bit Digital Signal Processor

The DY-70U applies JVC’s new DSP with advanced 14-bit video processing, which brings out natural details, eliminates spot noise, and accurately reproduces dark areas.

Three High-Density 1/2-Inch CCDs

Featuring three advanced 1/2-inch interline transfer CCDs and a 1/2-inch F1.4 RGB prism, the DY-70U delivers exceptionally sharp pictures. The high- resolution DY-70U features 380,000

effective pixels (768H493V). JVC’s innovative MICRO- LENSES, which are supported by a large light shield to reduce reflections and light leakages for minimal vertical smear, ensure highly efficient light conversion with a sensitivity of F11 at 2,000 Lux.

True Digital Camcorders

The DY-70U is a fully integrated digital camcorder which captures, processes, and records only digital signals for studio-quality acquisition. The result is sharply improved picture sharpness and image quality.

600% Wide Dynamic

Range

Multi-stream parallel digital pipeline processing at 40 MHz creates an ultra-smooth gamma curve

calculated using a true log scale WIDE DYNAMIC RANGE algorithm. The result is a dynamic

range of 600% to accurately reproduce fine details and colors in areas of both shadows and highlights.

NORMAL

LOLUX 0.75 Lux

When activated, the LOLUX mode increases sensitivity with almost no increase in noise. LOLUX lets you shoot in low light conditions, so you can capture high-quality video footage with excellent color balance at just 0.75 lux illumination.
