Leader introduces 4K HDR option for its 3G/HD/SD SDI Rasterizer

Leader Electronics Europe has announced a new option for the LV7390 4K-upgradable 3G/HD/SD SDI rasterizer. The new LV7390-OP20 4K upgrade allows the LV7390 to support 4K/UHD programme 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,” says Kevin Salvidge, Leader’s European Regional Development Manager.

“ITU.BT2100 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.

“Dolby PQ 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 is being introduced across the Sony range of broadcast and professional cameras and monitors.”

“The upgrade includes high dynamic range measurement capabilities for the ITU.BT.2100 Hybrid Log Gamma, Dolby PQ and Sony SLOG-3 protocols. This capability plus a compact 1U form-factor makes the LV7390 ideal for production environments that cannot accommodate a full size waveform monitor.”

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 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.
