Eyeheight to Exhibit LE-3G Multi-Rate Video Legalizer

Eyeheight's LE-3G multi-rate video legalizer in an FB-9E chassis with FP-9 control panel

Eyeheight's LE-3G multi-rate SD-SDI/HD-SDI video gamut legalizer will be introduced to visitors attending Inter BEE 2013 at Makuhari Messe on the eastern outskirts of Tokyo. Eyeheight will be represented on stand 4610 by MTC Japan.

Designed for use in television studios, broadcast ingest suites, post-production facilities and playout centres, the LE-3G is compatible with 1080i/50/59.94, 1080p50 and 1080p60, 1080p23.976/24/25/29.97, 720p/50/59.94, 625/50 and 525/59.94 television standards. Processing is to full 10-bit depth throughout.

The LE-3G provides fully automatic video legalization, ensuring full compliance with industry-agreed regulations for broadcast signal delivery. Single-touch presets enable fast configuration to 0 IRE pedestal (Japan), EBU-R103 (Europe) or 7.5 IRE pedestal (US).


Detailed configuration of the legalizer can be performed via an intuitive menu system common to all products in Eyeheight's geNETics series. Backlit LCD pushbuttons guide the operator through the various control modes, including RGB, YUV or composite mode selection, clipping level, soft clipping knee, luma and chroma gain, black level, and hue rotation. Six user memories are available to store group settings. A timecode-referenced output log is generated for viewing via a connected PC.

The LE-3G incorporates an out-of-gamut-indicate output with Eyeheight's unique visual severity monitor display. This shows the operator the location of any correction being carried out. An automation port provides PC-based access to preset parameters stored within the LE-3G. Firmware and software are fully updatable via file upload.


Up to six LE-3G modules can be accommodated in a 1 rack-unit Eyeheight FB-9E 19 inch chassis together with a single auto-switching dual-redundant power supply. Each module can be operated under local control from an Eyeheight FP-9 generic control panel mounted in front of the chassis, or remotely.

Options for the Eyeheight LE-3G legalizer include a Java-based softPanel control and specific web application.
