Intercom Goes Real-Time Ethernet with Riedel AVB Solutions
Connecting intercom panels over an Ethernet-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 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 AVBx8 panel interface.

Connect AVBx8 converts eight AES signals to AVB and vice versa. Built 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 AVBx8 is the perfect team mate 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:
·    802.1Qav specifies queuing and forwarding rules that shape the traffic to avoid bottlenecks at any bridge or end station.
·    P802.1Qat: defines the stream reservation protocol that sets up the path allowing a stream to go across the AVB cloud.
·    P802.1AS allows microsecond accurate time synchronization across all AVB nodes. Media is packetized following the IEEE P1733 and IEEE P1722 standards.

MediorNet Compact provides connectivity for up to 12 3G/HD/SD-SDI signals, four AES ports, two MADI interfaces as well as four analog audio I/Os with high-quality microphone preamps and a dynamic range of 117 dB. Furthermore, MediorNet Compact features an interface for Riedel RockNet digital audio networks, two DisplayPort outputs, three Gbit Ethernet ports and connections for serial data and GPIs. One Sync input and three Sync outputs complete the device’s interfaces.

MediorNet Compact is fully compatible with other MediorNet systems and supports all network topologies including ring, daisy-chain, star or any combination of these. The units can be equipped with various fiber connectors, ranging from install-friendly LC connectors to road-proof Neutrik opticalCONs with integrated WDM multiplexing technology.

MediorNet Compact comes in a 3RU housing and features integrated broadcast-quality signal processing tools such as Frame Store Synchronizer, Embedder/De-Embedder, Test Pattern Generator, On-Screen Display and Timecode Insertion at every port.

Riedel Pure – Heavy Duty Neutrik OpticalCon Fiber Cables for demanding Applications
Based on Riedel‘s extensive experience in demanding rental projects such as Olympic Games, Formula 1 or the Eurovision Song Contest, Riedel designed a fiber optic cable that meets the highest demands in event and mobile productions. With Pure, clients directly benefit from Riedel's expertise. Riedel Pure is a very flexible, abrasion and chemical resistant PUR jacket fiber cable available in two ruggedized versions.

Riedel Pure CS SM4 is a 5.7 mm tactical fiber cable exhibiting excellent impact and crush resistance while still remaining very flexible with low shape memory.

The Riedel Pure XT SM4 is a dual jacket heavy-duty fiber cable with a diameter of 9 mm. It is a metal free, heavy ruggedized and extremely strong tactile cable for extreme environments.

Riedel Pure has a low bending radius meeting G.657A specifications for the most challenging mobile applications, including outside broadcast, touring, sporting venues and stadiums.
