Leader Test Instruments Abound at Major 4K HDR APAC Sports Production
Seventy Leader test instruments have been chosen to perform signal monitoring at one of the largest outside broadcast projects in the 2018 sports calendar. Approximately 90 nations will compete in over 100 tournaments embracing 15 disciplines. Many of these will be captured in 4K HDR as well as 1080p SDR for relay to broadcast networks around the world. The instruments chosen comprise 32 LV5490 waveform monitors and 38 LV5770A 3G/HD/SD multi-monitors, all to be supplied via Leader’s UK-based rental channel partner Presteigne Broadcast Hire.
“This is by any standards a very large project and a great vote of confidence in the excellence of these instruments,” says Leader’s European Regional Development Manager Kevin Salvidge. “The sporting events will be produced in 4K HDR and distributed to the rapidly increasing number of broadcasters able to handle this advanced signal format. The LV5490 and LV5770A between them provide all the facilities required for camera alignment, live colour balancing and the wide variety of signal measurements that have to be made when setting up and operating large-scale outside-broadcast projects. Most will be installed for use in the main technical control centre, with the balance integrated into mobile production vehicles located at the various event venues. Both instruments are equipped with high quality picture monitors and can be fully controlled either from the front panel or remotely.”
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 HDR 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 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’s LV5770A multi-SDI monitor can monitor two 3G/HD/SD-SDI sources simultaneously and display picture, waveform, vector, 5-bar, CINELITE II, and status individually or in two or four split screen displays.
Eye pattern and jitter measurement capabilities (option SER09A) are available for evaluating the condition of SDI feeds. Optional digital and analog audio I/O provide for built-in de-embedding and digital-to-analog audio conversion. Audio facilities such as dual channel loudness logging, true-peak metering, lip-sync timing measurement and surround monitoring are also included. An integral USB port allows the use of a flash drive for storing captured screens, presets and software/firmware updates.
