Eyeheight Keeps French Open In-Bounds

Eyeheight’s video legalizing technology took center stage in Paris for the annual French Open tennis tournament. Held at Stade Roland Garros stadium, the event is the world’s premier clay court tennis championship. This year’s contest was transmitted to audiences worldwide from Sunday May 24 through to the finals on Sunday June 7.

Summer sports can be quite challenging for outside-broadcast camera crews, given the wide variation in light levels and the ever-present potential for bright reflections bouncing in from the public enclosure. The LE-2M ensured that video content captured throughout the series conformed fully to internationally agreed signal standards and levels.

The Eyeheight LE-2M auto-detects incoming SDI or HD-SDI video at 1080i/50/59.94, 720p/50/59.84, 625/50 or 525/59.94 and applies the appropriate legalizing format. It then ensures that incoming signal video is held within user-selected color-space parameters: RGB; YUV; composite (PAL or NTSC); or RGB-and-composite combined. Legalization can be performed to conform to EBU-R 2003 standard SDI settings and 7.5 IRE or 0 IRE Pedestal. Six user memories and common presets are provided.

Additional features include Eyeheight's unique clobberRing automatic luma overshoot and undershoot suppression together with luma and chroma gain, black level adjustment, hue rotation, adjustable clipping levels and soft-clipping-knee levels. An 'out-of-gamut' indication feed displays overshoot or undershoot severity and shows the user where on the picture any signal correction is being performed.

For audio, the Eyeheight LE-2M-K variant provides automatic real-time control of perceptual loudness and true peak level using ITU-R BS.1770 multi-channel loudness and true-peak estimation algorithms. The processor also performs 8x over-sampling true-peak estimation and instantaneous correction on all stereo or surround channels, ensuring peak-program level limit compliance.
