Intercom Goes Real-Time IP with Riedel AVB Solutions

Moscow, Russia (November 2, 2011). – Riedel Communications, one of the leading manufacturers of real-time networks for video, audio and communications, premiers a suite of AVB products for the Artist digital matrix intercom platform at this year's NATexpo in Moscow. AVB allows for transporting AES3/EBU audio in real-time with guaranteed bandwidth and quality of service (QoS) via IP-based Local Area Networks (LAN).

Connecting intercom panels over an IP-based LAN environment has been the dream of many system planers. But issues inherent to IP like latency, reliability and missing synchronization prevented them from doing so. Riedel’s AVB product line overcomes these issues and provides a real-time communication solution fulfilling the demands of professional intercom users. Based on official IEEE next generation Ethernet standards like 802.1Qav, P802.1Qat and P802.1AS, AVB allows risk-free utilization of AVB compliant facility or enterprise LAN infrastructure for intercom applications. This allows for new approaches in system and facility design providing significant savings in infrastructure investments.

Intercom applications for Riedel’s AVB products feature matrix-to-control panel connections via LAN, audio distribution via LAN, matrix-to-matrix trunking connections via LAN and distribution of digital partylines via LAN.

The Riedel suite of AVB products includes the AVB-108 G2 Client Card as well as the Connect AVB and Connect AVBx8 panel interfaces. The AVB-108 G2 card is a regular Artist client card to be used inside the Artist mainframe. It converts eight Artist matrix ports into AVB and vice versa. The AVB-108 G2 client card communicates either with other AVB-108 G2 client cards in another Artist systems, e.g. for trunking, or with Riedel’s Connect AVB and Connect AVBx8 panel interfaces.

The Connect AVB Panel Interface is a small unit, which converts an AES signal into AVB and vice versa. It is designed to connect one Artist control panel in one or two-channel mode to the intercom matrix via IP-based LANs.

Connect AVBx8 is the big brother of the Connect AVB interface, converting eight AES signals to AVB and vice versa. Build in a compact 9.5”/1RU housing the device provides eight CAT5 ports to connect up to eight Artist control panels in one or two-channel mode to the matrix via IP-based LANs. Connect AVB and Connect AVBx8 are the perfect team mates for Riedel’s AVB-108 G2 eight channel AVB client card.

About AVB
Audio Video Bridging (AVB), also known as Ethernet AVB, is the common name for the set of technical standards developed by the IEEE 802.1 Audio Video Bridging Task Group. Ethernet AVB adds latency guarantees and bandwidth reservation for media streams to the existing Ethernet protocols. Ethernet AVB requires AVB-compatible Ethernet hardware (switches & NICs) but remains backward compatible with existing Ethernet standards. This means that only the sections of a network that are supposed to send or receive AVB streams need to be updated to AVB compatible hardware. Unlike IEEE 1588 PTP based standards, AVB includes a stream reservation protocol, allowing one to use the same network infrastructure for IP-services (e.g. fileserver access, corporate network) and communications without risking delays or a loss of audio.

AVB Standards
Ethernet AVB is built upon a basis of three major standards:

Media is packetized following the IEEE P1733 and IEEE P1722 standards.
