GRASS VALLEY GV NODE

KEY FEATURES

• Provides vertically accurate switching and IP aggregation of up to 144x144 SDI or IP video signals
• Quiet audio switching of 4608x4608 audio channels (2304x2304 for local and 2304x2304 for aggregation)
• Embedding and de-embedding of AES67 audio
• Highly distributed topology, based on “spine-leaf” architecture that’s typical of modern IT infrastructures
• Industry proven built-in Kaleido multiviewer for high-quality picture and graphics monitoring
  • HDR-capable multivewer that supports HLG, PQ and S-Log3 gamma, and BT.2020 color gamut
• Small 4 RU footprint, typically requiring 40% less rack space than competitive systems with comparable weight reduction
• 1 TB of IP bandwidth for signal aggregation
• Up to 16 I/O processing modules:
  • Backwards compatible with all existing Densité modular processing
  • Fully integrated 9x2 multiviewer module, expandable to 54x4
• Compatible with the large installed base of Densité signal processing modules for production in a box
• High level of functional integration across IP switching, IP/SDI gateway, audio processing and multiviewing
• Support for the suite of SMPTE ST 2110 and 2022-6 and TICO compression (4K UHD-capable, scalable to 8K x 8K with one hop). Provides option to safeguard multicast traffic with SMPTE ST 2022-7 Class-D Ultra Low Scale redundancy
• Functional integration provides superior performance delivering reduced delay, fewer components and a better user experience
• Processes asynchronous and isochronous signals, as well as signals from a WAN or software source with high jitter rates for clean switching

A GV Node IP processing and routing node comprises the following elements:

• GV Node frame (4 RU) with 16 card slots which interface to an internal switch fabric that supports 9x9 3G-SDI and 288x288 audio channels for each card slot. High-speed aggregation ports (12x40 Gb/s QSFP+) offer interconnection with other chassis and switch fabric elements
• XIO-4901 coax SDI input/output module offers connections to legacy DIN/BNC-based SDI, ASI and MADI devices, and provides 9x9 SDI with audio mux/demux
• Compatible with NV9000, GV Convergent and other third-party router control systems

Optional I/O cards:
In addition to modular cards from the Densité product line, GV Node also offer cards with specialized functions.

• IPG-4901 IP Gateway — Leveraging the full SMPTE ST 2022-7 Class A specification to ensure uninterrupted reception of high jitter signals with multi-mode or single-mode SFPs from software-based transmitters and remote sources up to 40 km. When using SMPTE ST 2022-7 compliant sources, the IPG-4901 can align redundant sources which are out of synchronization. In conjunction with the GV Node 40G aggregation ports, the IPG-4901 can convert SMPTE ST 2022-6 and AES67 signals from the WAN to SMPTE ST 2110-20/30/40 signals on the LAN. Each IPG-4901 module supports up six 3 Gb/s sources or nine HD sources with AES67 audio de-embedding and embedding.  
• KMX-4921 Multiviewer — Supporting the same features and specifications as the earlier KMX-4911, the KMX-4921 multiviewer is SMPTE ST 2110-20 and SMPTE ST 2022-6 compliant and adds processing of high dynamic range (HDR) and wide color gamut (WCG) sources in HLG, PQ and S-Log3 HDR formats, and BT.2020 WCG. Each input is individually configurable, which allows to mix and match SDR and HDR sources, as well as different formats of HDR, on the same display. Requires KMX-4921-OPT-HDR license.
• Densité Signal Processing Modules — May be added to a GV Node frame.
