Leader Instruments Sharpens TV’s Leading Edge

HDR could be the next major innovation for television broadcasting ahead of the mainstream adoption of 4K/UHD. Leader Instruments Corporation made several announcements and product introductions related to both at the 2016 NAB Show, and joined the TICO Alliance.

High dynamic range (HDR) was one of the hottest topics across the 2016 NAB Show and in the Leader Instruments Corporation exhibit. Leader’s launch of a CINEZONE-HDR option for the LV5490 4K/HD/SD makes it one of the first test instruments allowing broadcasters and production companies to measure HDR while ensuring standard dynamic range (SDR) viewers are not compromised.

The 4K software upgradable version of the LV5490 positions it to become the standard test and measurement waveform monitor for the entire broadcast industry.

The LV5490SER07 HDR Option supports three methods of measuring HDR: ARIB STD-B67 Hybrid Log Gamma (HLG); PQ (SMPTE ST 2084); Sony SLog3. Like the established CINEZONE display, CINEZONE-HDR uses false colors to display areas of the HDR image that are outside SDR limits, making it easy for all production team members to identify potential issues. CINEZONE-HDR can be displayed on a traditional waveform display.

Leader also announced LV5490 support of 4K high frame rate (HFR) production signal analysis at up to 8x real-time, and a 12G-SDI interface option. The company also debuted a video over IP interface based on the Sony Networked Media Interface (NMI).

The company also announced LV5490SER06, a 12G UHD-SDI interface option with eye-pattern monitoring and jitter measurement for the LV5490 UHDTV waveform monitor. UHD-SDI is the only standardized broadcast UHDTV interface.

The board includes the Semtech GS12141 retiming equalizer and GS12181 retiming cable driver. The GS12141 retiming cable equalizer and GS12181 retiming cable driver, with their advanced feature sets and class leading performance, enable a commercial off-the-shelf interface solution for UHDTV equipment and infrastructure.

The LV5490 waveform monitor helps ensure productions are correctly acquiring HDR content, that editors and color grading facilities are delivering the full impact of HDR, and that transmission facilities are broadcasting HDR legally.

The LV5480and LV5490 also support a hardware upgrade to handle 12G-SDI (LV5490SER06) and video-over-IP operation as well as Dolby Digital Audio.

Leader introduced a software upgrade allowing the LV7390 rasterizer to be used in 4K/UHD production.

4K Rasterizer option

The Leader LV7390 is a 3G/HD/SD-SDI rasterizer is designed to monitor up to four sources at the same time. Compatible with 3G/HD/SD-SDI, and now optionally 4K, the unit can also monitor up to eight channels of embedded audio as standard.

It incorporates full-resolution 3G/HD-SDI and DVI-I rasterized outputs which allow detailed video and audio measurements to be checked on a separate monitor in full 1920 x 1080 HD resolution. The LV7390 can also be controlled remotely using a USB mouse.

New video sync gen

The company also showcased the new LT4610 3G/HD/SD multi-format video sync generator, designed for use in broadcast studios, mobile production vehicles, post-production companies and broadcast equipment maintenance facilities. It provides an exceptionally wide range of capabilities in 1 RU.

Test patterns include 100% and 75% color bars, multi-format color 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 color 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, and generate safety area markers to show safe-action area (90%), safe-title area (80%) and/or 4:3 aspect ratio.

The unit also generates several audio test signals. Test patterns with synchronized audio can be generated for lip sync testing. The audio click setting is disabled in this mode. SDI output 1 is synchronized to the AES/EBU output. When using Leader’s LV5770A waveform monitor users can accurately measure the lip sync of SDI video and audio signals.

The LT4610 has a genlock input and can be synchronized with NTSC/PAL black burst or HD tri-level sync signals. Standard support for SNMP via Ethernet makes it easy to integrate the LT4610 into a network environment. Alarms are generated with SNMP and displayed on the front panel.

2016 NAB Show summarized

"NAB 2016 attracted over 100,000 registered attendees from nearly 187 countries," comments Masahiro (Hiro) Sawa, president of California-based Leader Instruments Corporation."It was our busiest Las Vegas NAB for many years. We were especially pleased to see a significant increase in the number of European visitors following the establishment of the new Leader Europe operation. Our engineers have correctly anticipated the requirements of broadcasters and brought a fantastic range of new products to market ahead of the competition."
