"The Eyeheight color correctors were use to grade video from cameras on two motorcycles and two helicopters tracking the event," said Geoff Layton of SIS LIVE's Special Cameras Department. "The equipment is reliable and compact. Eyeheight's logical menu system makes operation straightforward which is very important during live coverage of major events. Although HD capable, they were used in SD mode for the Marathon." A high-quality multi-definition digital color corrector, Eyeheight's canalettoMDi is designed for use in 1080i and 720p HD-SDI television standards as well as 625i PAL and 525i NTSC SD. Integral HD-SDI/SDI autosensing enables the unit to switch automatically to the incoming feed. Input and output are both to 1.5 gigabit/s HD-SDI SMPTE-274 standard or SDI. Each R, G and B channel has individually controllable gain, lift and gamma together with overall hue correction.
An integral legalizer with automatic luma overshoot suppression and undershoot control ensures that canalettoMDi's output conforms fully to EBU R103-2000 at all color correction settings. Program-makers and broadcasters working to non-EBU standards can alternatively set legalisation levels to their specific regional standards. Full 10-bit processing is employed and six flash-RAM user memories are incorporated. The color corrector is available in half or full rack-width configurations. Two units can optionally be accommodated in the full-rack width version. The London Marathon has been held each spring since 1981. In addition to being one of the top five international marathons run over the traditional distance of 42.195 km, the event is also a large celebratory sporting festival.
