Performance for Production Professionals
High-quality 4:2:2 Component
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

D-9 Format
JVC’s D-9 format has established a reputation as a
workhorse format. Broadcasters and production
professionals rely on D-9 to deliver picture quality rivaling
the most expensive digital formats and reliability superior to
any video cassette format, analog or digital.

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.
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.

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 (768H
ן493V). 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.

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.
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
algorithm. The result is a dynamic
range of 600% to accurately
reproduce fine details and colors in
areas of both shadows and
highlights.
