Message Text: JVC announced the development of the world?s first 4K2K 60p camera capable of 60 progressive frame live signal output and 8.29 megapixel 4K2K (3,840 horizontal x 2,160 vertical), as well as a full-coverage, high-resolution Super Hi-Vision1 D-ILA projector.

Super Hi-Vision (SHV) is an experimental digital video format currently under development by Japanese NHK. Each each Super Hi-Vision image is approximately 33 megapixels (7,680 x 4,320 pixels) and supports 60 frame/second sequential scanning and 22.2 multichannel sound. Image format complies with the ITU-R BT.1769 and SMPTE 2036 international standards.



JVC 4K2K 60p Live Camera

JVC's first 4K2K 60p camera is capable of 60 progressive frame live signal output and 8.29 megapixel 4K2K (3,840 horizontal x 2,160 vertical), ultra-high-resolution images - approximately four times the resolution of full HD (1,920 x 1,080). The camera incorporates a single 1.25-inch CMOS image sensor and supports 12bit signal processing.

JVC has made the camera compact and lightweight (3Kg) enough since it is offering the processing function into a separate unit. The company's high-speed data transmission format (10Gbps) allows the processing device to be located up to a maximum 100m (328ft) away from the camera, granting users greater freedom of movement for more active shooting.





JVC plans to begin marketing the 4K2K 60p camera during fiscal year 2009 and is now accepting advance orders.

In 1996, JVC embarked on the development of Ultra High Definition image systems as the successor to High-Vision Definition. JVC later developed a 1.27-inch 4K2K D-ILA device with a 6.8μm pixel pitch and resolution of 4,096 x 2,400 pixels, and in February 2008 began marketing a newly commercialized professional D-ILA projector - the DLA-SH4K - incorporating that device.

First First Full-Coverage, High-Resolution Super Hi-Vision Projector

JVC's first full-coverage, high-resolution Super Hi-Vision1 D-ILA projector features 10,000 lumens of brightness and a 5,500:1 contrast ratio.

The projector is fully compatible with the Super Hi-Vision standard (7,680 x 4,320). Conventional Super Hi-Vision projectors render images with 4,000 TV lines using an 8.29-megapixel (3,840 x 2,160) single display device and leveraging adaptive pixel correlation technique to adjust the RGB green component; this means that the red and blue components are not fully covered. The new projector, however, uses a 35-megapixel (8,192 x 4,320) D-ILA single display panel that provides full coverage of each RGB component to 4,000 TV lines.

The projector generates a light output of 10,000 lumens - or one-and-a-half times greater than two conventional DLA-SH4K models - and provides sufficient brightness for displays as wide as 400 to 600 inches, each pixel approximately 1 sq. mm in size.



The Super Hi-Vision D-ILA projector also features world class environmental friendliness, using adaptive pixel correlation technique to display images at a one-and-a-half times brighter and three times higher contrast ratio than conventional D-ILA projectors while slashing power consumption in half. Conventional models are equipped with two 2,000-watt lamps to generate 7,000 lumens of brightness, but the Super Hi-Vision D-ILA Projector uses a single 3,000-watt lamp capable of 10,000 lumens, reducing power consumption by 50% and lamp cost by 60%.

Super Hi-Vision requires about 40 times more data than a standard high-definition image, so connecting a Super Hi-Vision unit to a conventional transmission system - HD-SDI, for example - requires at least 64 coaxial cables. JVC's new projector uses 36bit HDMI deep color specification to deliver data as a standardized image interface at a rate of 76 gigabits per second over just 16 coaxial cables - or one-fourth the previous amount - while offering greater flexibility of layout. Each RGB color also benefits from 12bit graduation expression.

As an alternative to HDMI signals that have a maximum transmission length of about 5m, the new projector?s optical interface delivers Super Hi-Vision signals over a longer distance. Developed in house by JVC, the optical transmission device employs four optical fibers to achieve high-stability, low-cost transmission.

The on-off switch is the only button on the projector unit, all other functions being controlled through a networked PC; this design promotes ease of maintenance and high operational flexibility given that projectors are generally installed in hard-to-reach locations.

In 1996, JVC embarked on the development of Ultra High Definition image systems as the successor to High-Vision Definition. The company developed the first 7.86-megapixel (3,840 X2,048 pixels) 4K2K D-ILA device in fall 2000 and began supplying projectors containing this device for research applications in March 2001. In June 2007, JVC developed a 1.27-inch 4K2K D-ILA device having a 6.8μm pixel pitch and resolution of 4,096 x 2,400 pixels, and in February 2008 it began marketing a newly commercialized professional D-ILA projector - the DLA-SH4K - incorporating that device.
