JVC Unveils Super-High-Res Video Products

Tokyo — JVC unveiled here Wednesday what it calls a 35-megapixel “full-coverage” high-resolution Super Hi-Vision1 D-ILA projector and a 4,000 by 2,000 60p camera with approximately four times the resolution of today’s FullHD 1080p systems.

JVC was calling both products “world’s firsts” in their respective categories.

The Super Hi-Vision1 D-ILA projector was said to have been developed through JVC’s ongoing efforts “to satisfy growing demand for next-generation high-definition imaging solutions for applications ranging from digital cinema and presentations to monitoring/control and health care.”

The projector has a 10,000 lumens brightness output and a 5,500:1 contrast ratio. It employs three D-ILA chips and an adaptive pixel correlation technique to display images that are 1.5 times brighter. The contrast ration is three-times higher than conventional D-ILA projectors. The use of a single 3,000-watt lamp, meanwhile, slashes power consumption to half that used by conventional projectors in its class, JVC said.

Super Hi-Vision (SHV) is “an experimental digital video format currently under development by NHK.” Each SHV image is approximately 33 megapixels (7,680 by 4,320 pixels) and supports 60 fps sequential scanning and 22.2 multichannel sound.

JVC said the projector is fully compatible with the SHV standard. Conventional SHV projectors render images with 4,000 TV lines using an 8.29-megapixel (3,840 by 2,160) single display device and an adaptive pixel correlation technique to adjust the RGB green component, leaving red and blue components only partially covered.

The new projector uses a 35-megapixel (8,192 by 4,320) D-ILA single display panel to provide full coverage of each RGB component to 4,000 TV lines, JVC said in a statement on the technology.

Light output was said to be sufficient for displays as wide as 400 inches to 600 inches, with each pixel measuring 1 sq. mm.

The large-scale projector’s 5,500:1 contrast ratio compares with the 1,000:1 to 2,000:1 contrast ratios that are typical of projectors in this class, JVC said.

The projector uses a 36-bit HDMI deep color specification to deliver data as a standardized image interface at a rate of 76 gigabits per second over 16 coaxial cables — or one-fourth the previous amount — while offering greater flexibility of layout, JVC said. Each RGB color also benefits from 12-bit graduation expression.

A JVC optical transmission device employs four optical fibers for high stability and low-cost transmission, the company said.

The on-off switch is the only button on the projector unit, with all other functions being controlled through a networked PC.

JVC’s new 4K2K 60p camera, meanwhile, produces a live signal output of 8.29 megapixels (3,840 horizontal by 2,160 vertical), which is roughly four times the resolution of common FullHD (1,920 by 1,080p) systems.

It uses a compact head that is housed separately from the processing function. JVC developed a high-speed data-transmission format allowing the processing device to be located up to a maximum 100 meters (328 feet) away from the camera, affording videographers greater freedom of movement.

JVC said it plans to begin marketing the video camera during its 2009 fiscal year and has started accepting advance orders.

The camera uses real-time processing of RAW data. JVC said the 4K2K ultra-high-resolution color signal output can be used “for a broad range of applications, including live presentations, monitoring/control and education and health care services.”

The RAW data is transmitted at a speed of about 10Gbps between the processing device and a sensor on the camera. For more challenging and creative video shoots, optical fiber can be used to connect the camera to the processing device, which can be placed up to a maximum 328 feet from the camera.

The 4K2K camera incorporates a single 1.25-inch CMOS image sensor and supports 12-bit signal processing.
