EMG chooses Leader multiscreen rasterizers

EMG, a broadcast service provider for sports, live events and studio-based production, has chosen Leader multiscreen rasterizerizing waveform monitors for integration into three new OB vehicles. A total of 16 LV7300 rasterizers, supplied by Leader channel partner Thameside.TV, will be used for master reference during live transmissions and related post-production.

Leader LV7300 rasterizers come in a compact 1U half-rack footprint. They provide signal generation plus a wide range of measurement tools and support SDI signals from SD through 12G. Waveform, vector, picture, audio, and SD-SDI to 12G-SDI eye-pattern displays enable comprehensive measurement and quality control of a wide range of audio and video formats. Measurement tools also include phase comparison, five-bar gamut display. A focus detection algorithm can be implemented to ensure precise camera adjustment when working with low-contrast source where traditional focus is difficult.

Detected errors captured on the LV7300's status display can be registered using event logs and long-term charts. SDI-embedded audio can be viewed as Lissajous waveforms as well as bargraphs. Also included in the instrument are Leader's CINELITE and CINEZONE. CINELITE offers in-picture measurement of RGB, luminance and f-stop levels, allowing real-time inspection of brightness and exposure levels. F-stop-based evaluation enables an operator to respond quickly to variations in lighting level. CINEZONE overlays false colors on the image to determine exposure zones.

Controllable from the front panel, via mouse or touchscreen, the LV7300 can be powered from 10-18V DC, enabling it to be used in locations where mains electricity is not available, or via a power supply unit. Rear-panel ports include two SDI inputs (12G and 3G), two SDI outputs, SDI and HDMI monitor feeds, 75-ohm external reference loopthrough, Ethernet and multipin remote interfaces plus DC power input.
