Agile Modular SDI/IP Processing Platform for Densite 3+


The Densité 3+ XIP-3901 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 IP connectivity of tomorrow. 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 link 3G/3G/HD-SDI connectivity to support two 4K UHD processing paths with dual 25 GbE SFP cages for future IP I/O migration. The XIP-3901 is installed in the established Densité modular frame. Due to advanced processing capabilities and power requirements, the XIP-3901 is supported by the Densité 3+ FR1 and FR4 frames. The initial applications for the XIP-3901 agile IP/SDI processing platform provides full functionality of up/down/framesync-gearbox processing capability delivered through three 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.

All applications will delay 12G/3G/HD embedded audio and metadata to maintain synchronization with video. The optional HDR processor, XIP-3901-UDC-HDR, allows conversion between SDR and HDR formats, supporting HLG (ITU-R BT.2100), PQ (SMPTE ST 2084, ITU-R BT.2100) and S-Log3/S-Gamut3 formats, with conversion between formats.
