Leader Announces 4K HDR Option

Leader’s new LV7390-OP20 4K upgrade allows the LV7390 to support 4K/UHD program production and post as well as 4x3G HD-SDI.

The Leader Electronics Europe division of Leader Instruments recently announced a major new option for the Leader LV7390 4K-upgradable 3G/HD/SD SDI rasterizer. It allows the LV7390 to support 4K/UHD program production and post as well as 4x3G HD-SDI.

"HDR does not come in one universal standard so is a potential nightmare for any producers who want to deploy this new technology to improve the look and feel of their production," said Kevin Salvidge, Leader's European Regional Development Manager.

ITU.BT.2100 Hybrid Log Gamma was jointly developed by the BBC in the UK and NHK in Japan. It is a royalty-free open approach specifying the system parameters essential for extended image dynamic range television. These include system colorimetry, signal format and digital representation.

The upgrade includes high dynamic range measurement capabilities for the ITU.BT.2100 Hybrid Log Gamma, Dolby PQ and Sony SLOG-3 protocols.

Dolby PQ HDR is a license-based proprietary standard. It uses the SMPTE 2084 electro-optical transfer function and has a peak brightness that can go as high as 10,000 nits.

Sony's SLOG3 HDR is being introduced across the Sony range of broadcast and professional cameras and monitors.

Also included with the 4K HDR upgrade is Leader's CINEZONE HDR. This uses false colour to display areas of the image extending into HDR so can be used on non-HDR monitors. Potential issues can be identified quickly and easily without demanding specialist technical experience. CINEZONE HDR reduces the need for re-takes or costly additional hours in post-production. It allows producers to acquire content in HDR whilst being able to ensure that content will not require additional re-working for standard dynamic range distribution. The CINEZONE HDR option also supports HD formats.

The Leader LV7390 is a compact 1U 3G/HD/SD-SDI rasterizer which can be used to measure up to four source channels simultaneously. It can be deployed for desktop or rack-mounted operation. Designed for easy connection into 3G-SDI, HD-SDI and SD-SDI systems, the LV7390 incorporates full-resolution 3G/HD-SDI and DVI-I rasterized outputs which allow detailed video and audio parameters be checked on a separate monitor in full 1920 x 1080 HD resolution.

The LV7390 can be configured by the operator to display waveform, vector, picture, audio and SDI status. Display layout is customisable from a wide range of available settings including individual full screen or user-defined combinations. These settings can be configured from the front panel or via a USB pointing device and saved for fast recall. 60 user-definable presets are accessible. A reference marker can be placed at any position on the rasterized image.
