CRT Projectors – TriDigital Technology
NEC Technologies today introduced the TriDigital HD4K reference projector, NEC’s most affordable projector to date incorporating TriDigital Image Processing for the clarity of digital and the look of film. The HD4K is designed for applications in postproduction suites, digital mastering facilities, screening rooms, medical facilities, high-end home theaters and entertainment venues where the most accurate reproduction of color, detail, white uniformity, and natural flesh tones is a necessity.
The TriDigital HD4K rounds out NEC’s TriDigital Series of projectors, joining the existing HD6K and HD10K.
“The TriDigital HD4K gives postproduction artists TriDigital Image Processing for unparalleled color fidelity and the brightness to enable vivid projection onto a 20-foot-wide screen,” said Steve Jackson, director of product development for Visual Systems at NEC Technologies. “This allows them to see detail and recreate the theater environment—where their work will ultimately appear—in the post facility like never before. And this unmatched image quality makes the HD4K perfect for screening room and high-end home theater applications as well.”
Before the TriDigital HD4K, post artists had to rely on small reference monitors that recreated colors accurately but lacked the size and visual impact possible with a large-screen display. Or they used difficult-to-maintain CRT projectors that lacked the brightness needed for a large screen to truly replicate the look of a film projector in a theater. The HD4K provides the first solution to couple 3500 ANSI lumens of brightness with TriDigital Image Processing to allow projection onto a larger screen with true color fidelity.
The TriDigital HD4K utilizes .9-inch 3-chip Digital Light Processing mirror technology from Texas Instruments, enabling a small size and weight. And the HD4K requires virtually no maintenance and integrates easily with existing systems. NEC Technologies additionally offers site personnel training for projector operation and maintenance for a smooth transition to HD projection.
The HD4K’s input flexibility guarantees compatibility with virtually every signal source. It features PanelLink digital connection interface for the cleanest, artifact-free computer connection possible, as well as an optional SDI—serial digital interface. Everything from video, component video and satellite to the highest resolution digital, computer and HDTV sources are easily displayed on the HD4K.
TriDigital Image Processing Technology
NEC’s exclusive TriDigital Image Processing uses three key steps to optimally decode film transfer material for digital projection. The ColorBit Pre-Processor decodes incoming signals. Then the Deep BlackBit Decoder extracts the maximum dynamic range of the original filmed image to produce deep, dark blacks with the contrast and detail of the original film material. Lastly, the Wide ColorBit Post-Processor manufactures an image that overcomes the projector’s RGB characteristics. This step is crucial because film is not an RGB medium, but instead is composed of dye particulates suspended in an emulsion that interact with the light from a traditional mechanical projector. “This is the essence of the look and feel of film,” explained Jackson, who added that the TriDigital Image Processing technology strives to duplicate the “age-old” mechanical and optical/light interaction of film within the “new-age” digital domain.
