Leader Electronics will demonstrate its new LV5600 true-hybrid IP/SDI waveform monitor plus the LT4610 video sync generator with PTP and 12G-SDI capabilities at the November 6-7 SATIS exhibition in Saint Denis, Paris. Exhibiting with French channel partner Audiopole, Leader will be represented by regional sales manager Djamel Djadi and colleagues.

The LV5600 was announced at NAB in April and is now deliverable, Djamel Djadi comments. It is designed to bridge the transition from today's predominantly SDI world to the everything-over-IP future. In entry-level form the LV5600 includes four 3G inputs allowing simultaneous display and measurement of up to four HD/SD-SDI channels. A reclocked loop output is available from each input. Leader's intuitive Cinezone and Cinelite also come as standard along with five-bar colour gamut display and CIE colour chart. Additional features can specified from a selection of interface and software-based feature options each customer's operating requirements evolve.

Leader LV5600

Leader's LV5600 is a mains-powered SDI/IP waveform monitor in a compact half-rack width 3U desktop chassis with a touch-screen front panel display. It provides all the facilities needed to monitor UHD/HD/SD SDI as well as video over IP signals seamlessly in a hybrid operating environment. Engineering-related features provided by the LV5600 include test pattern generation, eye pattern display, closed-caption monitoring, CIE colour chart, high dynamic range measurement, focus assist, customisable screen layout, tally interface, 4K/UHD operation, 10G IP input and 12G-SDI interfaces. SMPTE 2022-6, SMPTE 2022-7 and the recently published SMPTE 2110 protocols are all supported. The LV5600 also incorporates Leader's intuitive CINEZONE and CINELITE which are familiar to many content production staff.

Among the optional IP-specific features are the ability to monitor transmission errors such as packet loss and packet jitter and to simultaneously measure and display SDI and IP signal sources.

A companion instrument, the LV7600 rasteriser offers exactly the same capabilities as the LV5600 but in a low-profile 19 inch 1U form-factor for easy rack or desk mounting.

Leader LT4610

Designed for use in broadcast studios, mobile production vehicles, post-production companies and broadcast equipment maintenance facilities, the LT4610 provides an exceptionally wide range of video sync generation capabilities within a compact 1 U wide x 400 mm front-to-back footprint. Test patterns include 100% and 75% colour bars, multi-format colour bars and SDI check fields with user-selectable scrolling in eight combinations of up/down/left/right. Scrolling speed is user adjustable from 1 to 256 pixels or lines. Y/G, Cb/B, Cr/R components can be turned on or off independently for each output channel.

QVGA (320 pixel x 240 line) 24-bit full colour bitmap logos can be transferred into the generator via USB memory and added to any test pattern.

The LT4610 can also generate IDs of up to 20 characters for placement at any operator-assigned screen position. ID size is selectable between 32 x 32, 64 x 64, 128 x 128 and 256 x 256 pixel sizes at 100% or 75% intensity, continuous or blinking. IDs can be scrolled to the left or right.

Safety area markers can be generated to show safe-action area (90%), safe-title area (80%) and/or 4:3 aspect ratio. ID characters, logo mark, safe-area markers and test pattern can be displayed individually, sequentially or simultaneously.

Audio test generation capabilities include silence, 400 Hz, 800 Hz, and 1 kHz at -60 to 0 dBFS in 1 dBFS steps, assignable across up to 16 channels for 3G-A/HD/SD and 32 channels for 3G-B. Audio sampling resolution can be selected from 20 or 24 bit at 48 kHz and synchronised with the video signal. Audio clicks can be generated between 1 and 4 seconds or disabled.

Test patterns with synchronised audio can be generated for lip sync testing. The audio click setting is disabled in this mode. SDI output 1 is synchronised to the AES/EBU output. When using Leader's LV5770A waveform monitor you can accurately measure the lip sync of SDI video and audio signals.
