The Densité 3+ XIP-3901 from Grass Valley is an agile processing platform that focuses on high-quality live production for HD, 1080p, 4K UHD and HDR. 

This platform is a bridge for the hybrid world, consisting of today’s proven SDI technology and the new IP SMPTE ST 2110 connectivity. To meet customers’ needs both now and in the future, the XIP-3901 uses a flexible “virtualized” hardware platform. Based on a powerful FPGA engine, the XIP-3901 can be reconfigured with software updates for different applications as requirements change.

The XIP-3901 agile processing platform with a rear XIP-3901-3+DRP comes with all the 12G/quad link3G/3G/HD-SDI connectivity to support two 4K UHD processing paths with dual 25 GbE SFP cages for SMPTE ST 2110 IP I/O applications. The XIP-3901 is installed in the established Densité modular frame, packing lots of audio/video processing power in a small form factor results in savings in terms of space, power and weight. With advanced processing capabilities and power requirements, the XIP-3901 is supported by both Densité 3+ FR1 and FR4 frames.

The applications for the XIP-3901 agile IP/SDI processing platform provide full functionality of up/down/framesync-gearbox processing capability delivered through seven applications that allow your live productions — either from trucks, venues or stadiums — to make the most of the new 4K UHD and HDR formats. This includes playout channels where output of a 4K UHD HDR channel needs to be downconverted for an HD SDR simulcast version. 

• Densité 3+ XIP-3901-UC is an application that provides a dual-channel 12G/quad link 3G/3G/HD-SDI upconverter, which is designed to synchronize, upconvert and process HD and 3G 1080p signals for both 1080p and 4K UHD 2160p broadcast production. The XIP-3901-UC application features broadcast- quality scalers, motion-adaptive de-interlacers and color space conversions from ITU-R BT.709 to ITU-R BT.2020.
• Densité 3+ XIP-3901-DC is an application that provide a dual-channel 12G/quad link 3G/3G/HD downconverter, which is designed to synchronize, downconvert and process 4K UHD 2160p and 1080p for both 1080p and HD broadcast production. The XIP-3901-DC application features broadcast-quality down-scalers, interlacers and color space conversions from ITU-R BT.2020 to ITU-R BT.709. 
• Densité 3+ XIP-3901-FS is an application that provide a dual-channel 12G/quad link 3G/3G/HD frame synchronizer with gearbox functionality, which is designed to synchronize and convert color space between ITU-R BT.2020 and ITU-R BT.709 in 4K UHD, 1080p and HD broadcast productions.
• The XIP-3901-UDC-IP application is a dual-channel 4K UHD broadcast-quality format converter with optional HDR and audio processor, supporting IP with dual 25 GbE I/O. Based on open standards, this IP edge processing application is compliant to the SMPTE ST 2110 suite of standards and JT-NM TR-1001 technical recommendation for easy integration in a broadcast network production environment. 
• The XIP-3901-GB-IP is a dual-channel 4K UHD gearbox application for conversion between Quad-stream 1080p Two Sample Interleave or Square Division and Single-stream 4K UHD supporting IP with dual 25 GbE I/O. 
• The XIP-3901-UDC-IF application is a dual-channel 4K UHD or quad-channel HD broadcast-quality hybrid SDI/IP incoming feed processor with optional HDR and audio processor, supporting 12G/3G/HD SDI input/output, as well as IP with dual 25 GbE I/O.
• The XIP-3901-JPEG-XS application supports multiple channels of HD and UHD encoding/decoding between SMPTE ST 2110-20 uncompressed video and SMPTE ST 2110-22 high-quality compressed video using the JPEG XS standard. The application provides a low-latency encoding side and an optional SMPTE ST 2110 stream alignment is available on the decoding side to match production studio equipment top-of-frame reference, if needed.

Both XIP-3901-UDC-IP and XIP-3901-UDC-IF integrate all the video processing functions to perform the up/down/crossconversion needed to maintain chosen output formatting, irrespective of whether the input is HD 720p, 1080i, 1080p or UHD 2160p. High-quality up/down/crossconvertion is based on multiple sophisticated processing technologies including detail enhancement, pixel-based de-interlacing and advanced motion adaptive de-interlacing and anti-ringing.

The optional HDR processor available on some applications, XIP-3901-UDC-HDR, allows conversion between SDR and HDR formats and wide color gamut BT.709 and BT.2020, supporting HLG (ITU-R BT.2100), PQ (ITU-R BT.2100), and S-Log3/S-Gamut3 formats. In addition to the Grass Valley LUTs, you can select BBC LUTs v1.4 or you can choose your own custom LUTs compliant to Adobe cube file v1.0 for fully flexible HDR processing. The HDR processor operates in full 10-bit video signals with the ability to pass sub-blacks and super-whites in SMPTE Narrow video signals and the support of SMPTE Full in PQ and S-Log3 signals.

All XIP-3901 applications are configured, controlled and monitored by GV Orbit from Grass Valley, taking advantage of many features and functions specifically crafted to make IP easy. They can also be configured and controlled from iControl systems.

Based on the proven Densité modular framework, the flexible, space-efficient XIP-3901 agile processing platform can accommodate a gradual adoption of different production elements into 1080p and 4K UHD broadcasting workflows, all while protecting your investment in installed equipment. With flexibility to configure up to 12 XIP-3901 dual-channel processing applications per Densité 3+ FR4 frame, the Densité platform scales to a density of 24 4K UHD processors in a 4 RU frame. This means space and cost-efficient scaling today and tomorrow.
