Eyeheight's Award-Winning LEGAL-6 Heads for Hollywood

See Eyeheight on the Leader Instruments booth, 210

Eyeheight’s award-winning LEGAL-6 multi-rate video and audio legalizer logging legalizer will be introduced to visitors attending the SMPTE 2013 annual technical conference and exhibition in Hollywood, October 22-24.

Exhibiting on booth 210, Leader will demonstrate a full-featured system accepting SD/HD SDI sources (3G is an option) which legalizes video and audio levels (KARMAudio Loudness option) and outputs a corrected SDI signal for use in downstream processes.

Winner of a Broadcast Engineering Pick Hit award at NAB 2013, Eyeheight's LEGAL-6 supports RGB, composite (PAL, NTSC 7.5IRE setup and NTSC 0 setup), simultaneous composite + RGB and YCbCr SDI gamut correction. It maintains a timed record of every non-compliant video or audio event requiring correction in the course of a 24-hour transmission schedule. Each action is logged complete with its linear timecode identifier. This enables broadcasters to archive a statement of as-run conformance data. Video legalisation and loudness correction timelines can also be monitored on-screen.


Equipped to handle 525/625, 720 and 1080 line content, the LEGAL-6 incorporates 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.

With the KARMAudio Loudness option, the LEGAL-6 provides automatic real-time control of perceptual loudness and true peak level. Proprietary correction ensures compliance with loudness and peak-programme level regulations. Embedded stereo or surround audio loudness are continuously monitored, system gain being seamlessly adjusted across all channels to stay within the loudness limit while preserving audio imaging.


Eyeheight will be represented at SMPTE 2013 by Pete Anderson (Leader Instruments' Director of Western USA Sales) and Christian Young (Leader Instruments' Product Marketing Manager).
