Leader Instruments Demonstrates Advances In Broadcast Signal Analysis At CCW, New York

Leader Instruments demonstrated a range of advanced video and audio signal analysis products at Content & Communications World in New York, November 13-14. Held in the Javits Convention Center, the show was supported by over 280 exhibitors and is the largest East Coast exhibition and conference in the broadcast industry calendar.

Centre of interest on the Leader booth was the LV5490 4K-capable multi-standard multi-waveform monitor. First deliveries are expected in Q1 2014:

The LV5490 conforms fully to the Leader strategy of designing products for easy operation during live content creation as well as in post-production, presentation and engineering management, explains Leader Instruments Corporations president, George Gonos. It supports the full range of standard video production and transmission resolutions from 525 and 625 standard definition up to 3840 x 2160 and 4096 x 2160 4K. Equipped with four 3G-SDI/HD-SDI/SD-SDI input channels plus a high-quality wide-viewing-angle 1920 x 1080 9 inch flat-panel display, the LV5490 allows precise matching of studio or outside broadcast cameras. It also doubles as a picture monitor for production crews working on location.

Leaders S-LOG2 option for the LV5490 enables digital cinematographers to make the fullest use of the Sony F65 cameras 4K imager, extended chroma gamut and 16-bit linear dynamic range. It gives creatives immediate visual information such a precise zoom-in monitoring of focus across user-selected areas of a video source. User-adjustable exposure/luminance-referenced chroma scale can be applied over the image, allowing operators to match the White Clip indication on a Sony F65, False Color on an ARRI Alexa or Video Check on a RED Epic.

Also demonstrated were Leaders LV5770 compact broadcast signal analyzer and LV7770 rasterizing multi-SDI monitor. The LV5770 supports 3G, HD dual link, HD-SDI and SD-SDI formats. Its modular design allows easy customization. Signal amplitudes, vector, data, chroma bars and picture can be monitored individually or in quad-split mode on the instrument's integral 6.3 inch XGA LCD screen. Video frames can be captured manually or on an automated error-detection basis. Video display options include eye pattern and jitter waveform. Eye pattern rise time, amplitude, fall time, timing jitter, current jitter, rising-edge overshoot and falling-edge overshoot can be measured automatically.

Leaders LV7770 rasterizing multi-SDI monitor allows video and audio content to be checked on a much larger screen than can be accommodated in a portable instrument. It has two auto-sensing 3G-SDI/HD-SDI/SD-SDI inputs and can perform tests on a total of 17 video signal formats ranging from standard-definition up to 720p, 1080i and 1080p high-definition. Tri-level sync or NTSC or PAL black burst are accepted for external reference. The selected input is reclocked and can be fed downstream. Capabilities include waveform, vectorscope, peak video level display, SDI/external-sync phase difference, audio, picture and data monitoring functions. Displays can be viewed at full screen size or in assignable combinations. Extensive error detection and error logging facilities are incorporated, including gamut detection and adjustable error thresholds. Digital analysis screens Include data dump as well as equivalent cable length readings.

As US distributor for Phabrix, Leader displayed and demonstrated the SxA handheld video test signal generator, analyzer and monitor plus the SxE and Rx2000. Model SxE incorporates the functions of the SxA plus physical layer analysis. Eye and jitter diagrams can be viewed on the SxAs integral 4.3 inch 16:9 display screen. The Rx2000 is a rack-mountable test generator and analyzer employing the same graphic control interface as the Phabrix Sx range. Two rack units high and occupying just six inches from front to back, it can be tilted upwards or downwards within the rack bay, providing optimal viewing angles at various eye levels. The Rx2000 also provides monitoring via a 1920 x 1080 HDMI or HD-SDI output, allowing the user to create a multi-viewer display of waveform, vector, picture, audio, loudness, eye pattern which can be output to HDMI monitors or routed through broadcast infrastructures via SDI.
