Grass Valley Debuts Real-Time IP Processing

Its new GV Node platform uses a data center approach that lets companies quickly deploy new operations that would take months or even years to build in a traditional TV infrastructure, the company says.

Grass Valley topped a series of announcements at IBC Thursday day with an idea: why not adapt the data center, an IP platform often used in other industries, to the needs of television?

The company answered that question by unveiling GV Node, a new real-time IP processing platform designed to serve as a primary source of switching in live production.

The data center approach, already used by Google, Hulu, Netflix and other OTT providers, has half a dozen advantages that make it a compelling proposition for broadcast TV, said Mark Hilton, VP infrastructure products at Grass Valley, a Belden brand.

A data center approach allows companies to quickly deploy new operations that would take months or even years to build in a traditional TV infrastructure, Hilton said. It also offers scalability and an efficient use of computing resources, while allowing companies to quickly move data from one location to another without running into blockages.

Data centers also allow for quick fixes when problems arise and permit easy technology upgrades.

Until now, TV’s high persistent bandwidth demands, need for lower latency and greater computational demands would have prevented the creation of a data-center approach, Hilton said, adding that accurate switching posed another problem for the model.


GV Node’s distributed platform topology is designed to uplink to aggregation COTS IP switches using a “spine-leaf” architecture typical of modern IT infrastructures. This provides a 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.

Asked when GV Node will be available for installation, Hilton said the solution will be “real this year.”

In other news, Grass Valley unveiled XDR, an extended dynamic range software upgrade for its LDX 86 series of cameras. XDR permits producers to capture live action in extreme lighting conditions and shadow without compromise, the company said. It also provides colorists a much more precise light palette for recorded programming.
