Grass Valley Extends the Power of the Broadcast Data Center at IBC 2017

The new IPG-4901 gateway and KMX-4921 multiviewer joins GV Node and GV Convergent to meet upcoming broadcast standards and ensure interoperability

MONTREAL, September 12, 2017 — With the pressure on broadcasters to produce rich content in more settings than ever before, flexibility in broadcast solutions has never been more important. The rise of digital streaming and social media is adding demand for more formats, and as production teams work to switch over to IP they are juggling more workflow types with SDI, IP or a combination of both. To meet these diverse and ever-changing needs, Grass Valley, a Belden Brand, has cultivated strategic relationships and developed upgrades to key solutions that comprise the Broadcast Data Center to ensure that broadcasters' networking systems leverage the benefits of COTS hardware platforms and support the growing need for 4K and HDR workflows effectively.

At IBC 2017, Grass Valley will showcase multiple parts of the Broadcast Data Center: GV Node v2.1 and GV Convergent v1.3, both supporting the proposed SMPTE ST 2110 standards; the IPG-4901 gateway which normalizes IP signals sent to GV Node; the KMX-4921 Kaleido multiviewer, which is fully integrated into the GV Node platform and provides monitoring flexibility for HDR content; and Cisco Nexus 9200/9300 IP media network kits.

"Networking can literally be defined as an interconnected group. At a minimum, solutions need to be able to function together, but ideally, they connect seamlessly from start to finish," said Amit Eshet, vice president of networking, Grass Valley. "Adding the IPG-4901 gateway alongside the GV Node and GV Convergent delivers on Grass Valley's promise to give Broadcast Data Centers the utmost flexibility, compliancy and interoperability when it comes to IP workflows."

GV Node v2.1 is the cornerstone of Grass Valley's Broadcast Data Center. It offers integrated processing, routing, aggregation and multiviewing in an all-in-one platform, creating a cohesive solution for any environment whether SDI, hybrid SDI/IP or IP. GV Node's distributed architecture means it's ready for the facilities of the future. It's a truly next-generation routing and processing platform that continues to support advanced SDI-based workflows to leverage existing systems while making way for live telecasts over end-to-end IP.

The new KMX-4921 multiviewer comes fully integrated into the GV Node IP aggregation, processing and edge routing platform, offering the monitoring of HDR sources on current SDR displays, alongside SDR sources. The new model also boasts an increased I/O capacity to 54 x 4 and SCTE advanced probing features for critical monitoring in a master control room. This integration within GV Node eliminates cables between the multiviewer and the router, translating into cost and weight savings, providing operational simplification of a single chassis solution for routing and multiviewing.

As more broadcasters adopt IP solutions, GV Convergent v1.3 provides next-generation control of IP and SDI networks, including multilevel routing for the proposed SMPTE ST 2110 essence based flows, while also providing in depth visualization and control of the IP fabric. The complete control system is both infrastructure and signal format independent to adapt to unique facility needs and allow broadcasters to make real-time modifications through an intuitive interface and custom system configurations.

In combination with GV Node and GV Convergent, IPG-4901 offers Broadcast Data Centers the utmost in flexibility. This new gateway provides a robust feature set for normalizing variances in IP signals sent to GV Node. It takes signals that are not SMPTE ST 2110 and converts them, enabling enormous adaptability in IP workflows and creating a truly end-to-end IP solution. The IPG-4901 allows distribution beyond Local Area Networks; so together, GV Node with IPG can now offer the transfer of information with a distance of up to 40km between ports.

Grass Valley's NV8500 Output Gateway delivers up to 16 uncompressed ST2022-6 flows to a media network, allowing for limitless multiviewer expansion. With the NV8500, a bridge between SDI and IP infrastructure can be built, providing a managed transition between SDI to IP.

"In anticipation of full approval of the proposed SMPTE ST 2110 standards, the enhancements to Grass Valley's Broadcast Data Center mean it's AIMS compliant and ready for the future of IP," said Eshet. "Grass Valley embraces the many benefits of true data center-style architecture and our products reflect that."

As part of the Broadcast Data Center, GV Node, GV Convergent, IPG-4901 and the KMX-4921 multiviewer, along with COTS switches from Cisco and other providers, represent a robust and scalable IP solution that's fully standards compliant, offering ensured interoperability.

Grass Valley is demonstrating its networking solutions at IBC in stand 1.D11.
