Arista Networks and FOX Networks Engineering & Operations Showcase Next-Generation Broadcasting Technology at NAB 2014
SANTA CLARA, Calif. -- April 2, 2014 -- Arista Networks announced today a new demonstration of next-generation broadcasting technologies at the annual National Association of Broadcasters (NAB) Show. The demo, a joint effort with FOX Networks Engineering & Operations (FOX NE&O), will showcase technology to support the migration of legacy broadcast plants to packet-based Ethernet networks, allowing broadcasters to benefit from Ethernet and Data Center economics.
FOX NE&O has developed a concept for performing seamless switching of uncompressed, broadcast-quality HD video through the use of Software Defined Networking (SDN) and commercial-off-the-shelf (COTS) Ethernet switches. Arista supports a wide range of SDN technologies in its Arista EOS (Extensible Operating System) software. This demonstration, called “Source-Timed SDN Video Switching,” uses Arista’s DirectFlow technology to perform dynamic steering of network flows and facilitate precisely timed, automated control of real-time media streams.
The Arista / FOX NE&O demonstration shows frame-accurate, seamless switching of uncompressed HD video carried over SMPTE 2022-6 IP Multicast streams. The ability to perform frame-accurate switching is a requirement of broadcast networks and should be supported in a packet-based infrastructure for migration to the next-generation Ethernet broadcast plant.
“FOX NE&O believes that the broadcast plant of the future will look more like a modern data center with lots of servers and network switches, instead of the legacy plant which has miles of unidirectional point-to-point SDI cables and expensive, custom AV hardware” said Thomas Edwards, VP of Engineering and Development at FOX Networks Engineering and Operations. “The flexibility and potential economies of scale obtained with a modern infrastructure based on commercial off-the-shelf data center equipment is extremely compelling,” added Edwards.
Additionally, Arista is announcing support for the IEEE Audio Video Bridging standards (known as AVB) in several of Arista’s Ethernet switch product lines with demonstrations of video transport over AVB with AXON and audio transport over AVB with Riedel Communications. AVB allows high-quality real-time media to be reliably transported over Ethernet networks with accurate time synchronization.
Legacy media networks were built using point-to-point connections such as Serial Digital Interface (SDI) for video and AES3 digital audio. Such legacy networks have massive and complex wiring plants, cross point switches with limited flexibility and are very expensive due to a limited market size for the technology. AVB allows professional media to be reliably transported over an Ethernet network with the benefits of a packet-based infrastructure; greatly simplified cabling, great flexibility in signal routing and processing, and the advantage of extremely low costs due to the ubiquitous nature of Ethernet.
“AXON is very pleased that Arista is helping to broaden the ecosystem for building AVB solutions” said Jan Eveleens, Chief Executive Officer of Axon Digital Design. “We believe that AVB is an important set of standards for allowing Ethernet technology to be widely applied to the world of broadcast.”
