24 SPECIAL REPORT: AV OVER IP

June 2017

Learning the lessons As we continue our special report, Michael Burns investigates how AV over IP is being implemented across a number of different verticals

A

V over IP is an evolution in media transport. Why use multiple different types of cables to carry video, audio, reference, metadata and control data, when a single standard network cable passing through conventional network switches will do the job? It may seem like a no-brainer for simplifying AV, but not so long ago some AV professionals were fearing a loss of responsibility and a degradation in media quality and security if they moved more towards standard internetbased solutions. IT professionals on the other hand felt in danger of being overwhelmed by challenges of supporting and managing the integration of live video and audio (and their users) into their network infrastructure. Those days are gone, according to Michael Crisci, business development manager AV/IP and strategic alliances, Atlona. “The uptake of AVoIP is on the rise,” he says. “Solutions are addressing IT-specific needs like network redundancy, AES encryption and forward error correction within the AV environment. The fears of IT and AV convergence have passed.” “As more traditional AV applications become IP connected, so too do traditional AV products,” says Rainer Stiehl, vice-president of marketing, Europe, Extron Electronics. “Many customers are interested in leveraging their data network as the transport infrastructure for AV in addition to their business-class

data like email, fi le transfer, and voice over IP. There are some unique capabilities and potential benefits when streaming video and audio information over the network, such as scalability, reach and flexibility.”

Big business “AVoIP’s expandability and scalability are undoubtedly huge advantages over legacy technology using a classic video matrix,” agrees Tom Strade, technology & innovation VP, Black Box. “It took some time for network administrators to accept the integration of AV on their networks but AVoIP is well established nowadays.”

AVoIP applications in the corporate space addressed by Strade’s company include providing signage across multiple displays in large halls or meeting rooms. “Physical

Key Points „ AV over IP is becoming well established; leading sectors include corporate, control rooms, education, and sports venues „ Issues around signal quality and latency have generally been solved „ Rising video data rates will bring more pressure on bandwidth and so the need for compression will increase „ More education is needed within the AV community to spread the use of AVoIP technology further distance is also not a problem anymore – using AVoIP, your AV reaches as far as your network reaches,” he says. “Using our mediacento IPX in conjunction with our Coalesce Wireless collaboration system, you could share and work on a single presentation across multiple floors using AVoIP.” “Corporate facilities are a melting pot of AV environments that all work with AVoIP technology,” observes Crisci. “Atlona’s redundant capabilities and ultra-low-latency solutions work well in meeting spaces from huddle spaces to large conference rooms, creating interconnected virtual matrixes.” Mark Stanborough, sales manager, EMEA & APAC, Cabletime, reveals that his corporate customers, such as Bloomberg, PwC and KPMG, have been using AVoIP solutions to distribute live TV and digital signage over existing IP
