AV over IP for corporate
Today, we will investigate how AV over IP is being implemented across a number of different verticals, starting with corporate.
AV 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 internet-based 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, file 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.”
“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 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.”
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 networks all over their buildings. This will not suit all levels of customers, though.
“The installation of a broadcast-style service, or fit-for-purpose digital signage in a corporate environment, is a big undertaking for any organisation, and the technical barriers can seem daunting,” he says. “Integrators specifying solutions have to establish whether the network infrastructure can cope. The IPTV network must be capable of sustaining bandwidth-intense, high-availability multicast transport streams carried in the standard MPEG2 transport stream across multiple subnets, vLANs and WANs. Without this in place, the system will not perform to maximum capacity.”
Security is a critical factor when looking into AVoIP solutions in this sector, particularly when employees can easily hook up their own devices to a wired or wireless IP network.
“The stakes are now higher,” says Stijn Ooms, EMEA product director at Crestron. “Sensitive content like executive presentations or HR employment and salary information is now accessible anywhere there’s a network drop. Rogue devices can access protected content. As a result, anything that goes on the network must be secure, and clients need to know who and what is on their network.
