JVC GY-HD250 Brochure & Specs page 5

GY-HD250
Professional ProHD camcorder with super-smooth 720/60p
imaging for ENG and sports acquisition, plus a 26-pin connector
for studio use.
With 720/60p capture and recording capabilities,
the GY-HD250 delivers full-resolution HD images,
ensuring the high resolution and smooth motion
critical to news and sports field production. Equally
proficient in the studio, the GY-HD250 can easily be
converted for studio use with the optional KA-HD250,
a specially designed studio adapter incorporating
an industry-standard 26-pin multi-core connection.
Other valuable features of this versatile camcorder
include genlock capability, component and HD-SDI
output, a wide selection of HD lenses, enhanced
cinema gamma, external time code synchronization
and professional connectors on a rugged die cast
chassis.
From live field recording to high-end studio
production, the GY-HD250 is the cost-effective
solution to today's demand for high-
quality imaging.

14-bit A/D converter
To improve both the S/N ratio and the horizontal resolution, a new 14-bit A/D converter was specially developed by JVC to prevent signal
deterioration and to generate a fourfold increase in gradations.
Wideband front end processing
The ProHD camcorder uses a wideband analogue front end to process its CCD sampling via the 14-bit A/D converter. This further
improves the S/N ratio and horizontal resolution by optimising the CCD drive circuitry. The new LVDS (Low Voltage Differential Signal)
interface minimises any other possible signal degradation and so contributes to the improved S/N ratio.
Newly-developed pixel converter
To enable 720p/50 recording, a new super encoder and a new pixel converter were developed, incorporating an adaptive filter which
optimises the scalar performance of cross-converted signals, including 1080i. The resultant effects are increased resolution and reduced
aliasing. Objects thus have much more natural looking edges and images are therefore extremely lifelike in appearance.

Linearity
Horizontal resolution and signal-to-noise ratio have been
enhanced, making the already high ProHD picture
quality even better. Together with ProHD's superior
colour reproduction, these improvements ensure true
professional quality HD imaging. These are JVC's key
technology innovations.
