Leader to introduce ZEN Series LV5600 and LV7600

Leader Electronics Corporation has chosen IBC 2018 as the launch event for two powerful additions to its range of broadcast quality test and measurement products: the LV5600 true hybrid IP and SDI waveform monitor, and the LV7600 rasterising equivalent – both form part of Leader’s new ZEN series.

The Leader 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.

A broad set of engineering-related features are provided by the LV5600 including 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.

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

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.

The LV5600 and LV7600 can be configured from a selection of interface and software-based feature options, enabling customers to specify the capabilities needed for their current requirements. Among the feature options are closed caption measurement, CIE chart display, HDR, SDI signal generation, ID/iris/tally display, 4K and 12G-SDI.

“Leader has helped many broadcasters and broadcast-equipment manufacturers manage their migration from analog to digital, from standard definition to high definition and from standard dynamic range to high dynamic range,” says the company’s president, Kozo Nagao. “Most broadcasters now recognise the potential of video over IP both within their studio facilities and for long distance content delivery. The majority will transition to IP via an interim SDI/IP hybrid infrastructure so they will want to handle SDI and IP in a single test and measurement product. The LV5600 and LV7600 address this concern, providing common display interfaces, irrespective of whether the source signal is SDI or IP. Both instruments conform to the Leader style of being intuitive for camera operators to use as well as for engineering staff.”

The LV5600 true hybrid IP and SDI waveform monitor and LV7600 rasterising equivalent will make their IBC debut.

 

Leader to demonstrate HDR test and measurement at Media Production Show

Leader Electronics will demonstrate the advanced HDR measurement capabilities of its LV5490 4K multi-screen video and audio test instrument at the Media Production Show in London taking place from 12 to 13 June. Leader will be represented by managing director Koichi Fukagawa and European regional development manager Kevin Salvidge.

“HDR offers television producers and digital cinematographers double the dynamic range of SDR provided they take full advantage of it right through the production chain,” Kevin Salvidge comments. “The LV5490 provides full direct support for HDR production in full conformance with ITU-R BT.2408-0 recommended practice. In cooperation with Jigsaw24, we will be showing how that translates into actual operation both during the initial shoot and onward through colour grading and post-production.”

The LV5490 4K/HDR waveform monitor supports preconfigured settings to ensure the reference levels are correct for both HLG and Dolby PQ production. A 75 per cent HLG or 58 per cent PQ marker is also displayed automatically on the waveform monitor graticule. This represents the reference level, enabling the vision engineer to ensure that any object placed at the centre of interest within a scene occupies the appropriate signal range and that sufficient headroom is reserved for specular highlights.

Another recently added feature is system gamma Optical-Optical Transfer Function functionality for HLG and Sony ‘SR-Live for HDR’ workflow.

Leader’s LV5490 offers 4K, UHD, 3G, HD and SD test and measurement features in a half-rack-width by 4U portable unit with a full high definition 9 inch front-panel monitor. It provides all the capabilities needed to implement the full potential of high dynamic range in both HD and UHD.

Signal displays such as video waveform, chroma levels, colour vectors, bar graphs, noise, video patterns, quad-3G phase, data tables, camera picture output, colour chart, multichannel audio levels and surround-sound vectors can be viewed simultaneously in a user-customisable layout. If a specific element requires detailed attention, this can be selected quickly for viewing at higher resolution or full-screen.

The Leader CINELITE HDR toolset also comes as a standard feature of the LV5490, allowing easy assessment of relative exposure and overall luminance during production. A focus-assist option allows highly accurate on-set adjustment of camera focus to match the ability of 4K and UHD formats to handle very precise image detail.

Supplementing its front-panel display, the LV5490 provides 1920 x 1080 HD DVI and HD-SDI feeds for connection to external monitors. Simultaneous viewing of up to four 3 gigabit/s SDI inputs is possible, including overlays. The size and location of individual channels can be adjusted on the display using a USB pointer so the user is not limited to fixed-size quadrants. Operators can select the size and position of the measuring area as well as the Y/G/B/R component channel. An alarm can be set to alert operators if the noise level exceeds a predefined threshold. An integral low-pass filter allows elements of the high frequency band to be removed at the time of noise measurement.

Leader simplifies HDR production

Leader Electronics has chosen BVE 2018 as the UK launch platform for a major addition to the feature set of its LV5490 4K high dynamic range waveform monitor. The instrument now provides full direct support for ITU-R BT.2408-0 ‘Operational practices in HDR television production’. Published in October 2017, the ITU document provides initial guidance to help ensure optimal and consistent use of the Hybrid Log-Gamma and Perceptual Quantizer techniques specified in ITU-R BT.2100.

The LV5490 4K/HDR waveform monitor supports preconfigured settings to ensure the reference levels are correct for both PQ and HLG production. A 75 per cent HLG or 58 per cent PQ marker is also displayed automatically on the waveform monitor graticule. This represents the reference level, enabling the vision engineer to ensure that any object placed at the centre of interest within a scene occupies the appropriate signal range and that sufficient headroom is reserved for specular highlights. Also now added to the LV5490 is system gamma Optical-Optical Transfer Function functionality for HLG and Sony’s SR-Live for HDR production technology.

Leader’s LV5490 offers 4K, UHD, 3G, HD and SD test and measurement features in a half-rack-width by a 4U portable unit with a full high definition 9-inch front-panel monitor. It provides all the capabilities needed to implement the full potential of high dynamic range in both HD and UHD. Signal displays such as video waveform, chroma levels, colour vectors, bar-graphs, noise, video patterns, quad-3G phase, data tables, camera picture output, colour chart, multichannel audio levels and surround-sound vectors can be viewed simultaneously in a user-customisable layout.

A focus-assist option allows highly accurate on-set adjustment of camera focus to match the ability of 4K and UHD formats to handle very precise image detail.

Additionally on show at BVE 2018 will be the LV5333 portable 3G waveform monitor. Designed for HD and SD signal monitoring, this now supports five methods of displaying log-based gamma curves: Hybrid Log Gamma, Dolby PQ, Arri Log-C, Canon C-Log and Sony S-Log3.

Hybrid Log Gamma (ITU.BT2100): Jointly developed by the BBC and NHK, HLG is an open royalty-free approach which specifies the system parameters essential for extended image dynamic range television including system colourimetry, signal format and digital representation. The LV5333 comes preconfigured with HLG presets of 50 per cent and 75 per cent reference. This reference can be adjusted to satisfy productions requirements.

Dolby PQ (SMPTE ST 2084): Developed by Dolby PQ is a license-based proprietary standard. It uses SMPTE 2084 EOTF and can go as high as 10 000 nits peak brightness. The LV5333 comes preconfigured with PQ presets of 1 000, 4 000 and 10 000 nits reference. This reference can be adjusted to satisfy productions requirements.

Log-C: Used by Arri when encoding images on its cameras. Log-C curve is a set of curves for different exposure indices. The LV5333 supports exposure indices of 200, 400, 800 and 1 600.

C-Log: Used by Canon when encoding images on its cameras.

S-Log3:  Developed by Sony this being introduced across the company’s range of broadcast and professional cameras and monitors.

Compatible with over 20 HD-SDI/SD-SDI formats, the Leader LV5333 is designed for deployment in studios or technical areas, or attached to a camera tripod. The integral 6.5-inch XGA TFT LCD screen can also be used to display video signal waveform, vectorscope or the video image. Cinelite, Cinezone, histogram, gamma display, gamut and level error display functions are included as standard. Additional features of the LV5333 include cable length display, external timing display and field frequency deviation display. SDI-embedded audio can be extracted and two user-selectable audio channels sent as an AES/EBU stream to a BNC output. The levels of up to eight audio channels can be checked using on-screen bar displays. User-configurable multi-display combinations within the LV5333 allow easy inspection of signal parameters. Full-screen displays can alternatively be selected to allow a detailed review of specific elements.

Video Europe chooses Leader LV5490 for latest OB truck

Video Europe, one of Europe’s largest and most active equipment and resource hire
companies, has chosen Leader’s LV5490 4K/HDR multiscreen waveform monitor as
the reference test instrument for its latest outside broadcast and live event production
truck. The LV5490 was supplied by Leader European distribution partner Thameside
TV.

Designed and equipped by Leeds-based system integrator WTS, the new vehicle is the
first in Video Europe’s fleet to feature both 3G-SDI and 12G-SDI infrastructure.

“The truck is specified to cater for two quite distinct markets,” says Video Europe
engineer Richard La Motte. “It is equipped with 3G-SDI capabilities for use with Sony
cameras in a traditional live broadcast mode. 12G-SDI connectivity is also included to
interface with Arri cameras for cinematic projects. We were impressed by the Leader
LV5490 as it provides all the test and measurement tools required for both modes.
Operational and production staff appreciate the straightforward and easy to
understand graphical displays, especially the real-time CIE colour chart and real-time
false colour HDR display. We have the LV5490 installed in a vision engineering position
on the truck. The HD-SDI output is connected to the router so it can be displayed on
any HD-SDI monitor in the vehicle. With our current configuration, the external feed
from the LV5490 is simultaneously displayed in the gallery where the producer and
director can view the overall production.

“Our investment in 12G-SDI product development is now starting to materialise into
real projects, comments Leader’s European Regional Development Manager, Kevin
Salvidge. “Many broadcast channel owners are content to sit back and wait for IP
standards to be finalised but production service providers have to meet the demands
of forward-looking programme-makers. The combination of IP and 12G-SDI provides
the ideal platform for 4K/UHD and HDR production. The LV5490 enables Richard and
his team to operate with full confidence in both 3G-SDI and 12G-SDI.”

“The ability to handle 12G and 3G-SDI simultaneously makes the Leader LV5490 a
very powerful piece of test and measurement equipment,” adds Thameside TV’s
Regional Sales Director Chris Margrave-Gregory. “The LV5490’s compact footprint,
integrated display and ability to drive a large external monitor also makes it ideal for
OB applications.”

Leader’s LV5490 offers 4K, UHD, 3G, HD and SD test and measurement features in a
half-rack-width by 4U portable unit with a full high-definition 9 inch front-panel
monitor. It provides all the facilities required to implement the full potential of high
dynamic range in both HD and UHD.

Signal displays such as video waveform, chroma levels, colour vectors, bar-graphs,
noise, video patterns, quad-3G phase, data tables, camera picture output, colour
chart, multichannel audio levels and surround-sound vectors can be freely integrated
into a combined display. If a specific displayed element requires detailed attention,
this can be selected quickly for viewing at higher resolution or full-screen.

The Leader CINELITE HDR toolset also comes as a standard feature, allowing easy
assessment of relative exposure and overall luminance during production. A focus-
assist option allows highly accurate on-set adjustment of camera focus to match the
ability of 4K and UHD formats to handle very precise image detail.

Supplementing its front-panel display, the LV5490 provides 1920 x 1080 HD DVI and
HD-SDI feeds for connection to external monitors. Simultaneous viewing of up to four
3 gigabit/s SDI inputs is possible, including overlays. The size and location of
individual channels can be adjusted on the display using a USB pointer so the user is
not limited to fixed-size quadrants. Operators can select the size and position of the
measuring area as well as the Y/G/B/R component channel. An alarm can be set to
alert operators if the noise level exceeds a predefined threshold. An integral low-pass
filter allows elements of the high frequency band to be removed at the time of noise
measurement.

Leader demonstrates 4K IP test and measurement technology at Sony IP Live Studio

Leader Electronics Corporation, a globally active producer of high-grade test and measurement solutions, has further demonstrated its support for promoting the advancement of IP-based production. The company participated in the recent launch of a dedicated IP Live Studio in Sony’s Digital Motion Picture Centre Europe (DMPCE) at Pinewood Film Studios near London. Leader supplied its flagship LV5490 4K/HD/SD waveform monitor, giving broadcasters and production companies the opportunity to gain hands-on familiarity with IP-based live production environments.

“We have been working jointly with Sony since the launch of the DMPCE in 2013,” says Leader’s European regional development manager,” Kevin Salvidge. “Many European customers have been introduced to 4K at the DMPCE, and more recently to high dynamic range production techniques. It was logical to have Leader’s LV5490 with Sony Networked Media Interface (NMI) available for DMPCE clients as they explored the advantages of IP-based live production.”

“Leader has been working closely with Sony since the initial announcement of the NMI Alliance. The LV5490 4K with an IP Live Studio interface was first demonstrated at NAB 2016 in Las Vegas. We are pleased to be part of this important initiative to provide media companies with the practical knowledge necessary for making the most efficient possible use of IP connectivity within their production infrastructure.”

Leader is a long-time member of the IP Live Alliance and has demonstrated interoperability with Sony’s NMI, both in the lab and in commercial deployments of IP-based live production environments. The Leader LV5490 deployed in the IP Live Studio is fitted with the LV5490SER08 – IP (NMI) option. This supports traditional SDI video formats and Sony IP. Supported 4K video formats include 4096 x 2160 and 3840 x 2160 via multiple link as well as 4 x HD signal monitoring via IP.

Live production requires exacting precision and reliability. Broadcasters need assurance that IP-based solutions can meet and exceed these requirements before moving operations out of the baseband domain. A fully functional IT-based production facility is designed to provide these assurances through extensive hands-on training, as well as offering technology partners the ability to demonstrate widespread interoperability in a multivendor environment.
