Leader Introduces LV5490 SD/HD/4K Monitor At IBC2014

Leader lnstruments is to introduce upgrades to its LV5490 SD/HD/4K picture and signal monitor at IBC2014 in Amsterdam, September 12-16.

Enhancements include two-sample interleave, focus assist, frequency deviation auto-correction, phase difference detection, CIE 1931 chart with 4K colour space and user-adjustable measurement display sizes.
"The LV5490 is a high-precision broadcast test instrument with an unprecedented number of features," comments Richard Heath, Leader's European Regional Development Manager. "It can be used in a very wide range of roles including precise matching of up to four studio or outside broadcast cameras at a time. It also doubles as a picture monitor for production crews working on location. The LV5490's multistandard versatility makes this instrument ideal for use in standard-definition, high-definition and 4K ultra-high-definition standards, all in one compact housing with a 223 wide x 360 millimetre deep footprint and a height of 189 mm."
Up to four channels of 3G-SDI input signals can be displayed simultaneously. Eight input channels are provided. Four of these are on dedicated connection ports with cable length measurement capability. The other four channels are configurable as inputs or outputs with pattern generation functions. The built-in 9-inch LCD monitor is full 1920 x 1080 HD with a wide viewing angle and high quality color reproduction. The LV5490 also has a DVI and HD-SDI rasterizing monitor output.
Leader will demonstrate the enhanced LV5490's ability to deliver a 4K image in either square-division or two-sample-interleave format. In square-division signal mode, the entire image is split into four quadrants and each quadrant is transmitted in turn as a sub-image. In the case of two-sample-interleave, two consecutive pixels are transmitted at a time. The first pair goes to sub-image 1 and the second pair to sub-image 2. The first pair of the next line then goes to sub-image 3, the first pair of the next line going to sub-image 4, and so on). Each sub-image is transmitted separately to the monitor. This type of two-sample interleave is the approved standard for 4K.
Frequency deviation, now standard on the LV5490, allows detection, display and automatic correction of any frequency difference that may exist between each of the input signals.
The LV5490 can also measure and display any phase discrepancy between Input A or an external reference signal and the other input signals. Any phase difference detected could be caused by a shift in the line number of the image.
Also new to the LV5490 is a CIE 1931 color space chart generator. 4K signals conforming to ITU Recommendation BT.2020 have a larger colour space than HD signals. The LV5490 can show 4K signals in the standard's full colour space.
Exhibiting on stand 11.A38, Leader will be represented at IBC2014 by Masahiro (Hiro) Sawa (President, Leader America), Richard Heath, Koichi Fukugawa and Christian Young.
