Leader’s latest additions on show at NAB

Leader Instruments will exhibit additions to its range of broadcast-quality test and measurement solutions at NAB. Leader’s LV5490 will be on show, and the FS3140 quality control software will be making its NAB debut.

The company’s LV5490 multi-display picture and signal monitor now supports video production and transmission resolutions from 525 and 625 standard definition up to 3840×2160 and 4096×2160 4K. Equipped with four 3G-SDI/HD-SDI/SD-SDI input channels plus a wide-viewing-angle 1920×1080 9-inch flat-panel display, the LV5490 allows precise matching of studio or outside broadcast cameras.

Test and measurement capabilities of the LV5490 include waveform, vector and picture monitoring, SDI signal data analysis, cyclic-redundancy-check error, embedded-audio error, event log, data dump and timing display. Leader’s CINELIT II toolset also comes as standard.

The Leader FS3140 combines the waveform and vectorscope displays which users rely upon, plus automated QC software. Designed for use in analysing file-based video and audio, it can be deployed on a web-based Windows server, allowing rollout across Windows, OS X or Linux environments.

Control of the FS3140 is via an interface which allows QC parameters to be user-configured from a portfolio of tests. A test specification can quickly be imported into the FS3140 for customised content verification. A key feature of the FS3140 is its ability to identify issues which can be seen and heard. This is achieved using perception-based artefact detection, multi-level block-noise analysis, black-frame detection, freeze-frame detection, silence detection and filtered audio noise sensors.

Other file characteristics which can be checked with the FS3140 include metadata, macroblock noise, letterboxing, pillarboxing, profane captions, blurring, comb artefacts, field swaps, peak audio levels, test tones, audio transients, channel phase, average loudness and mono-in-stereo.
