Leader To Introduce LV 790 4-channel g/HD/SD-SDI Rasterizer At IBC05

LEADER has chosen IBC2015 as the venue for the European introduction of the LV 7390 multi-standard rasterizer. First demonstrated at the NAB show in April and now deliverable, the LV 7390 can be used be to measure up to four SDI signals simultaneously. It occupies just 1U and can be deployed for desktop or rackmounted operation.

Designed for easy connection into 3G-SDI, HD-SDI and SD-SDI systems, the LV 7390 incorporates full-resolution 3G/HD-SDI and DVI-I rasterised outputs which allow detailed video and audio parameters be checked on a separate monitor in full 1920 x 1080 HD resolution.

Measurements can be displayed as waveform, vector, picture, audio and SDI status. Display layout is user customisable from a wide range of available settings including individual full screen or user-defined combinations. These settings can be configured from the front panel or via a standard USB pointing device and then saved for fast recall. 60 user-definable presets are accessible. These can be labeled and displayed on-screen. A reference marker can be placed at any position on the rasterised image.

A screen capture function allows the operator to send the displayed image as a BMP file to a removable USB memory device. This feature can be used for matching cameras or documenting a shot for purposes such as continuity or technical trouble-shooting.

Transmission line measurement for each SDI input can be displayed numerically in terms of equivalent cable length, allowing the safety margin to be checked quickly.

Video Engineer (VE) menus are provided for use in camera shading correction. When activated, they can be accessed at the press of a single button.

The integral CINELITE feature allows the user to measure the luminance levels at different points in a scene (up to 3 points). CINEZONE uses false colors to indicate luminance levels in a scene and is particularly suited to green screen chroma-key virtual-set alignment.

Additional features include error logs and alarms, format and timecode display, and SDI analysis data dump with hexadecimal values for YCbCr, EAV and SAV search. Status display provides information on a variety of error monitoring functions such as CRC, TRS position, illegal code, and line number SDI errors, checksum and parity ancillary data errors, BCH, parity, DBN, inhibit, and embedded audio errors. Ethernet connectivity allows remote control via an internet or extranet connection. The LV7390 supports TELNET, FTP, HTTP, and SNMP protocols.

Optionally available for the LV 7390 are separate SDI inputs which can display signals from up to four camera viewfinders, including the in-viewfinder menu configuration. This facility allows camera operators to monitor the settings of remotely located cameras, typically from a studio control room or mobile production truck.

Future options will include eight-channel digital audio I/O ; eye-pattern and jitter measurement ; 4K signal measurement capability .

The LEADER LV 7390 operates from 90-250 volt 50/60 Hz mains at 90 watts maximum.

LEADER representatives attending will include Hiro Sawa (President of LEADER Instruments Corporation), Richard Heath, Koichi Fukagawa, Christian Young and Koji Yano. The company will be exhibiting on stand 11.A10.
