  • OVERVIEW

    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 — confirmed by our successful participation in JT-NM tested events in August 2019 and March 2020.

    The XIP-3901-UDC-IP integrates 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/crossconversion is performed at both 50 and 59.94 Hz, based on multiple sophisticated processing technologies. These include detail enhancement, pixel-based de-interlacing and advanced motion adaptive de-interlacing and anti-ringing.

    The optional HDR processor, 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.

    Four streams of SMPTE ST 2110-30/31 audio conforming to Level A and Level C is supported per video channel, giving a total of 224 channels of audio with automatic delay to keep lip sync. The XIP-3901-UDC-AUD option gives advanced processing control with audio level, delay, up and down-mixing, and shuffling for additional flexibility.

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