Grass Valley, a Belden Brand, debuts at IBC 2015 the world's first true, real-time IP processing platform, GV Node. Offering multipurpose video and audio processing, vertically accurate switching and IP aggregation, GV Node is a critical next step in the growth of Grass Valley's Glass-to-Glass IP solution for broadcasters, enabling them to apply the unprecedented flexibility of IP in more applications throughout their workflows. GV Node allows broadcasters to combine many of the advantages of a data center model with the specific requirements of a live broadcast production environment.
This unique IP processing node is designed to serve as a primary source of switching in live production. In early applications, customers may choose to operate GV Node alongside commercial off-the-shelf (COTS) IP switches to offer paths with deterministic switching that are ideal for backup in direct-to-air and secondary live feed applications. Historically, COTS IP switches have been unable to perform vertically accurate switching like traditional SDI routers. This is especially important in live applications where signals go directly to air, and where routers have traditionally been used as a backup to the production switcher. Switching that happens accurately within the vertical interval is also needed when a router is used for connecting secondary live feeds.
"GV Node's distributed architecture means that broadcasters can start their IP infrastructure with a small system, and grow quickly and linearly as their needs change," explained Mike Cronk, senior vice president of strategic marketing, Grass Valley. "This exceptional integration of functions into one device enables broadcasters to build compact, cost-effective and efficient solutions."
The GV Node distributed platform topology is designed to uplink to aggregation COTS IP switches, using a "spine-leaf" architecture that's typical of modern IT infrastructures. This topology represents a much more scalable and flexible approach than traditional, centralized routing systems, which have encouraged the purchase of larger, more expensive chassis than necessary in order to allow future expansion. This type of distributed topology enables the realization of a true broadcast-centric data center model.
GV Node delivers multiple signal processing and monitoring functions and provides IP and SDI I/O as well as MADI I/O, audio de-embedding/embedding and monitoring. The built-in, highly scalable multiviewer uses industry-proven Kaleido technology for the highest picture quality and layout flexibility. GV Node is designed to be "Future-Ready" with respect to currently changing industry signal formats and standards, currently supporting both SMPTE 2022-6 (HD) video-over-IP and 4K 1-wire using TICO compression.
"IP is certainly a proven technology in a variety of industries," observed Cronk. "However, there are a number of nuances in the broadcast space that require a specific IP solution. GV Node meets those needs and positions users for the opportunities to come."
