Eyeheight showing 3D video legaliser, colour corrector1 February 2012
The LE-3D – which is claimed to be the world’s first dual-channel stereoscopic 3D video legaliser – was developed in co-operation with one of London’s leading broadcast production, post-production and distribution facilities.
The new launch allows legalisation parameters for left and right video channels to be adjusted from a single operating panel to ensure precise compliance. User-adjustable settings include 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. EBU 2003 standard legalisation presets are also provided.
Based on Eyeheight’s geNETics platform, the LE-3D has two independent HD-SDI inputs and outputs. Processing is to full 10-bit depth throughout. Multiple LE-3D modules can be accommodated in a 1 RU 19 inch chassis for operation under local control from an Eyeheight FP-9 generic control panel. All geNETics products are driven via a unified hardware or software menu system giving fast and easy access to all relevant parameters.
Video legalisers are a simple way of helping edited programmes pass broadcasters’ technical quality-assurance requirements. They automatically detect and correct any parts of a video signal that do not conform to industry-agreed component RGB, YUV or composite colour space levels.
Also on show at BVE will be the CC-3D, described as the world’s first multi-rate stereoscopic 3D colour corrector. Designed for use in broadcast production, post-production and playout centres, the Eyeheight CC-3D allows both channels of a stereoscopic 3D pair to be corrected under common single control.
The CC-3D’s adjustable colour correction parameters include R, G, B and master gain and lift, plus selectable master or individual R, G and B gamma control with overall luma, chroma gain, hue rotation and black level.
An integral legaliser automatically ensures that adjustments remain within industry-agreed signal levels. Default legalisation settings are to EBU Technical Recommendation R103-2000. Alternative legalisation parameters can be set and stored. The legaliser is equivalent to a stand-alone Eyeheight RGB legaliser including overshoot suppression and six user memories.
Eyeheight’s CC-3D colour corrector is capable of working at 1080i/50/59.94 or 1080p 23.976/24/25/29.97 high definition, 720p/50/59.94 intermediate definition and 625/50 or 525/59.94 standard definition.
Housed in a 1 rack-unit chassis, the CC-3D can be operated from an Eyeheight FP-9C colour corrector control panel. A single control panel can also be networked via CAT5 (Ethernet) cable to drive multiple CC-3D systems. An optional browser-based Java software panel is available.
Full 10-bit processing (16-bit internal) is used throughout the CC-3D. A mechanical relay bypass option is available.
