Eyeheight’s LE-2nM fully-featured HD/SD SDI multi-rate video legalizer makes its US market debut at the 2010 NAB convention in Las Vegas, April 12-15. Shown in prototype at IBC 2009 and now in full production, the LE-2nM 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 legalising format. The LE-2nM then ensures incoming signal video is held within user-selected color-space parameters: RGB; YUV; composite (PAL or NTSC); or RGB-and-composite combined. Legalisation can be performed to conform with EBU-R 2003 standard SDI settings and 7.5 IRE or 0 IRE Pedestal. Six user memories and common presets are provided.
Additional features of the legalizer 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.
Supplied as a fully integrated package, the LE-2nM is designed to be operated from an Eyeheight FP-9 Flexipanel or via a Java-based graphic user interface running on USB-linked Windows PC or Apple Mac. Firmware and software are fully updatable by file upload. The USB connection socket is located on the front panel together with power and status LEDs and 7.5 V power input.
Full 10 bit processing is employed throughout the LE-2nM. The legalizer is housed in a compact rack-mountable or free-standing third-rack-width 1 U high nanoBox chassis. A mechanical relay bypass option is available.
In addition to the Le-2nM, two variant models are available. Model LE-2nU has essentially the same features plus the capability of 1080p dual link operation. Model LE-2nS is a standard-definition version.
