AVB for IT Professionals
What is AVB and What Does It Do?
AVB is a collection of IEEE 802.1 standards that have increased the capacity
for information exchange, support and AV product standardization. Commonly
referred to as a switch, the purpose of an audio video bridge is to provide time-
synchronized, low latency streaming capabilities for audio and video data that
guarantees bandwidth reservation.
The promise of AVB is a single network to transmit audio, video and other
forms of data via “smart” switches that can process AVB traffic without
compromising network integrity. Using AVB, an IT manager can have a mixed
data network, making their responsibilities as the manager of AV systems
much more time- and cost-effective than parallel systems. Integrating AVB
technology into their current IT systems would be a giant step forward and a
radical shift in design philosophy most IT and AV administrators.
The AVB-Related IEEE Standards are as Follows:
• 802.1AS: Timing and Synchronization for Time-Sensitive Applications
• 802.1Qat: Stream Reservation Protocol (SRP)
• 802.1Qav: Forwarding and Queuing for Time-Sensitive Streams
• 802.1BA: Audio Video Bridging Systems
• 1722 is a Layer 2 transport protocol for time sensitive applications in
bridged LANs. Relates to media talker and listener endpoints only.
• 1733 is a Layer 3 transport protocol for time sensitive applications in
LANs that leverage Real-Time Transport Protocols (RTP) and RTP Control
Protocols (RTCP), two protocols commonly used in VoIP.
• P1722.1 is responsible for AVB device discovery, enumeration, connection
management and control for 1722-based devices. It is currently going
through the balloting process prior to acceptance.
Industry-Supported and Future-Proofed Solutions
AV equipment connections have historically been analog one-way, single-
purpose and point-to-point. Even digital AV standards were often point-
to-point and one-way, such as S/PDIF for audio and the serial digital
interface (SDI) for video. This connection model resulted in large, confusing
masses of cables, especially in professional and high-end consumer
applications.
With the increase in larger scale project installations in recent years, AV
integrators are looking for system solutions that can accommodate their clients’
growing needs for more flexible and scalable options in their AV systems. Our
answer is to provide customers with an industry-supported and future-proofed
solution for their AV systems. As Biamp’s newest networked media system,
Tesira incorporates features and functionality that we’ve been developing since
the launch of AudiaFLEX. The biggest difference in Tesira, as compared with
other similar systems, is the level of scalability it provides.
