Low Latency KVM over IP Applications: A WorldCast Promise

0

WorldCast, the supplier of advanced broadcast and connectivity products, used the 2022 NAB Show to promote the release of “SureStream for KVM,” a “transformation,” it says, of KVM infrastructures ensuring pixel-perfect transmission, latency free video and “flawless” audio — even over imperfect IP networks.


This ground-breaking solution is based on SureStream technology, which is now being extended into the broadcast control room.

KVM is an acronym for “Keyboard Video Mouse,” and response times between on-premise and co-location production and playout environments are essential for a control room. As WorldCast notes, “jitter, latency, packet loss and the rubber mouse phenomenon continue to plague any applications that leverage IP networks.”

Enter WorldCast, which believes it has a solution.

Ken Kearney, R&D Manager for APT & SureStream Range at WorldCast Systems, said, “Media companies no longer need to deploy dedicated network infrastructure for remote KVM systems to ensure high performance. With SureStream the transmission is flawless, with latency-free video and audio delivery. They can send KVM, audio, and serial signals to networked stations or video monitors at scale to wherever the IP network extends, without sacrificing QoE.”

The SureStream KVM combines all available network links into one single link. This virtual trunk (V-Trunk) technique optimizes the available bandwidth. The second step involves packet loss protection. SureStream technology can guarantee virtually zero packet loss while utilizing 50% of actual trunk bandwidth capacity.

Kearney comments, “With IP-based systems, there is no limit to the number of endpoints that can be added to a KVM system; the only limitation is the bandwidth of the user-supplied network that supports the system. SureStream delivers peak bandwidth performance across IP networks with no packet loss, regardless of location, making the transition to IP-based systems and their inherent architectural flexibility and cost advantages more practical for broadcasters.”
