Eyeheight announces CC-3G multi-standard auto-legalising colour corrector
15 August 2012: Eyeheight announces a new addition to its range of auto-legalising colour correctors. The CC-3G is designed for use in digital cinema production, post and presentation as well as high-end television. Compatible with latest-generation 3 gigabits per second infrastructure, it accepts all commonly used standards from interlaced 525/625-line standard definition up to progressive 1080-line 50-frame and 1080-line 60-frame high definition.
The CC-3G allows fast adjustment of colour balance to ensure visual consistency between adjacent sequences and throughout a programme. An integral legaliser automatically conforms outgoing signals fully to user-defined standard output parameters or to the default EBU Technical Recommendation R103-2000. This is a vital concern given the potential of equipment operating in YUV colour space to exceed the levels specified by broadcasters and transmission service-providers for content delivery through RGB-based and composite networks.
Control of the CC-3G is via a dedicated panel. Adjustment of red, green and blue component levels, lift and master gamma as well as overall luma, chroma gain, black-level adjustment and overall hue can be performed in real time. The CC-3G also uses Eyeheight’s proven and effective luma overshoot and undershoot suppression.
Configurable parameters such as legalisation levels are accessible via an intuitive menu system based on LED pushbuttons with electronically generated legends. Settings assigned by one or more operators can be stored in six internal non-volatile memories.
The CC-3G incorporates a colour-corrected output plus a preview output. Individual R, G, and B indicators on the preview output show legalise-clipped areas. Original and colour-corrected video can be compared via an operator-adjustable split screen. Other features include auto-sensing SD/HD SDI inputs, error-detection handling/cyclic-redundancy check reinsertion and full 10-bit internal processing.
Using Eyeheight’s I-Bus network, each panel can control up to six plug-in modular colour correction cards in a single-rack-unit smart-chassis. This makes the CC-3G one of the most compact colour correctors on the market. Up to eight panels can be networked. The system also includes a maintenance mode to assist installation.
Eyeheight (www.eyeheight.com) designs and manufactures SDI/HD-SDI equipment for programme-origination, quality-assurance, post-production, playout and associated areas. This includes hardware legalisers, logo generators, safe-area generators, keyers, colour correctors and aspect ratio converters. Eyeheight products are available worldwide.
