We're integrating standardized SMPTE 2022-6 IP support into every major product category we offer, so you can migrate to IP on your terms when it makes business sense for you. This includes cameras, switchers, routers, servers, replay and multiviewers. All while maintaining SDI support.
GV Node: The World's First True Real Time IP Processing and Routing Platform Datasheet (GVB-1-0336K-EN-DS) File size: 1.9 MB, posted Feb 27 2019 GV Node delivers a broadcast-centric, real-time, distributed routing and IP processing node that supports IP and SDI workflows with vertically accurate switching and integrated video and audio processing, including Kaleido multiviewing for live production, playout and general purpose infrastructure.
CHALLENGE: Create the world's first all-IP, UHD OB fleet.
SOLUTION: Grass Valley and Arena, with technology partner Cisco, designed a network topology using a spine and leaf configuration, based around a 2.88 Tb/s Nexus switch.
BENEFITS: OBX is completely flexible, format-wise, and can be configured for 4K UHD, 3G, HD, even SD, without the need to re-cable.
Lighter payload compared with Quad-SDI solutions, and equipment can be distributed more evenly around the OB truck (unlike a conventional SDI router).
Why Shaping Traffic at the Sender is Important Whitepaper by Chuck Meyer, Chief Technical Officer, Production, (GVB-1-0657B-EN-WP) File size: 1.3 MB, posted Mar 05 2019 To manage this risk in advance, broadcasters should consider how the buffers in the switch work and ensure that data senders behave in such a way that the buffers never become too full. This practice is known as sender traffic shaping. To ensure pre-compensating for this adverse effect is efficiently applied to IP, broadcasters must follow one rule: the network must be designed and managed for the desired traffic load.
Shaping sender traffic is important for system reliability, and it is equally important to consider its impact for low latency and jitter in live production systems. To ensure the optimal workflow and performance, use the proposed SMPTE 2110-21 standard as a way to design the system, and then verify this, as well as system performance requirements, with your router vendor.
Aggregation is Key to Optimizing IP Network Design Whitepaper by Chuck Meyer, Chief Technical Officer, (GVB-1-0650C-EN-WP) File size: 1014.3 KB, posted Mar 05 2019 The world of IP technology moves rapidly. The speed with which data moves through an Ethernet connection and the amount of bandwidth that connection can accommodate increases at a rate that makes network planning challenging. What makes it even more challenging? Usually, higher bandwidth interconnects, such as active optical connectors, are initially more expensive and less available due to their rapid adoption by data center and telecommunications installations. Supply eventually catches up to the demand, but costs sometimes make early adoption prohibitive.
In the world of broadcast and media distribution, IP networks are being deployed to exploit the benefits that this technology presents: scalability; simplified geographic distribution; workflow efficiency; and the promise of future bandwidth increases. They are also being deployed in an effort to provide faster adoption of new media distribution services and formats as the role of traditional broadcast evolves into a more consumer choice-driven business model.
Building an IP Fabric with Cisco Products Whitepaper by Chris Merrill, Senior Product Manager Infrastructure, Strategic Marketing
Alexandre Gagne, Senior Product Manager, Monitoring & Control, Strategic Marketing, (GVB-1-0620D-EN-WP) File size: 1.2 MB, posted Mar 05 2019 Cisco's IP fabric for media solution replaces what previously was the crosspoint section of an SDI router in live production studios with an IP-based infrastructure. The Cisco Nexus 9200/9300-EX platform switches in conjunction with the Cisco non-blocking multicast (NBM) algorithm (an intelligent traffic management algorithm) provide a reliable, scalable IP fabric for the broadcast industry. In addition, this IP fabric solution provides zero-drop multicast transport and support for PTP media profiles.
