TV equipment manufacturers are now increasingly focusing on ultra-high definition (UHDTV) products. In addition to the higher resolution, the advantage of UHDTV is the improved visual quality implemented in HDR technology. In 2015, SkyLark Technology started supporting the UHDTV format. The first customer of SkyLark UltraHD products in 2018 was the European network of sports channels Eurosport, In May 2018, the first servers of Channel In A Box UltraHD with HDR HLG support successfully worked on French tennis championship Roland-Garros. The «Eurosport 4K» channel is formed by SL NEO equipment and software.
The SL NEO line of products features the following:
High resolution video: 3840×2160 pixels;
Support for all range of frame rates: 24/25/29.97/50/59.94/60 FPS. Since UHDTV uses progressive scanning, it is possible to achieve the usual «smoothness» of the image, similar to «interlaced» systems, with frequency values of 50 Hz.
Support of the ITU-R recommendations for the color space: BT709, BT2020 with a wide color gamut (WCG) during recording, file import and playback;
Dynamic conversion between BT709 (SDR) and BT2020 in combination with PQ and HLG formats (HDR) in capture, recording, playback, conversion, preview;
Up/cross — conversions for ingest and import: upscaling HD > UHD and frame rate conversions, with interline and interframe interpolation;
Input/output interfaces/protocols: 6/12G SDI, 3x4G SDI, H.264/265 or SMPTE ST2022−6, SMPTE ST2110 over IP, UDP/RTP/RTSP/RTMP, HDMI 2.0 with PQ and HLG metadata generation;
Supports SMPTE ST2022−7, SMPTE ST2110 using Nvidia NIC cards with 25/50/100G interfaces. The 25G interface provides I/O support for 2 channels of UHDp60;
Support for IP encoding is implemented using the power of the CPU or using the NVIDIA GPU. H.264 and H.265 YUV 4:2:0 formats.
Features of the SL NEO platform are actual in generation of UHD programs when mixed content is used, when in HDR-program the source content is partially present in SDR format and vice versa:
Capturing SDR signals from Live sources and on-line conversion to HDR when forming the HDR output program;
Import of files with BT709 (SDR) color space and automatic conversion to HDR;
Generation of proxy-copies when capturing, importing files, real-time preview of mixed SDR/HDR content on network workplaces with SDR monitors;
Graphics design for UHDTV programs in both SDR and HDR modes. Editing, previewing graphical compositions on networked workstations;
When making UHDTV SDR programs in cases where the content is partially present in HDR, HDR-SDR conversions are performed during capture and file import.
