NEC has engineered a replacement technology for the ordinary video decoder called TriDigital Image Processing. TriDigital Image Processing entails three key steps to optimally decode film transfer material for digital projection. First, the ColorBit™ Pre-Processor decodes incoming signals to satisfy the unique requirements for film based materials.
The Deep BlackBit™ Decoder then extracts the maximum dynamic range of the original filmed image to produce deep, dark blacks that still exhibit the contrast and detail of the original film material. This is achieved without increasing the background noise level or producing detail contours inherent in conventional electronic projector systems that attempt to deliver dark area detail. Lastly, the Wide ColorBit™ Post-Processor manufactures an image that overcomes the RGB characteristics of the projector - characteristics that would otherwise make the image appear as video. This element of the process is crucial because film is not an RGB medium, but instead, 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. The TriDigital Image Processing system strives to duplicate the "age-old" mechanical and optical/light interaction of film within the "new-age" digital domain.
In addition to the display of the highest fidelity of film based material, images from virtually any source can be displayed on the NEC HD4K. This would include private or open DSS satellite, DVD, VHS, video servers, DigiBeta decks and many other sources. The TriDigital HD4K can also display a multitude of video standards both analog and digital such as NTSC, PAL and SECAM, SDTV, HDTV in 4:3 and 16:9 aspects and an incredible assortment of computer generated images
