SHOW REVIEW: IBC2013
AUDIO NETWORKING There were plenty of audio distribution and networking technologies on show at IBC as well.
Clear-Com launched a new
capability of its HelixNet partyline intercom system: multiple HelixNet systems can now be networked together to distribute audio to digital beltpack users. This is made possible with

well. It’s the most cost- effective approach. Switches by the likes of Cisco are ubiquitous and affordable, and most buildings are wired with Cat5 or Cat6. So there’s a big cost saving to be made going to IP.” KVM system manufacturer Guntermann & Drunck showcased its advanced ControlCenter-Digital modular KVM matrix switch. This allows users to operate up to thousands of computers over hundreds of consoles consisting of keyboard, monitor and mouse simultaneously – even over long distances. If fibre is employed, users and computers can be up to 10,000m apart.
Up to 288 ports can be supported, and thanks to the ControlCenter-Digital’s modularity, all parts of the matrix can be easily replaced, and the cards are hot- swappable and hot- pluggable. Cards are available for single-link DVI, audio, VGA, USB 2.0, multi-monitor, RS232, DisplayPort and USB keyboard/mouse. One interesting feature is
display switching: users can move the mouse pointer seamlessly from one display to another, even when those displays are showing content from completely separate computers. Matrox was demonstrating
its Avio fibre-optic KVM extenders and Maevex video distribution technologies. Avio enables computers to be placed remotely from operators, perhaps in a climate-controlled room. Receivers and transmitters are joined by a duplex fibre connection, with no compression and no latency. This supports either two single-link DVI signals or one dual-link – typically 2,560 x 1,600 at 60fps or 4,096 x

2,160 (4K) at 30 fps. Two Avio systems can be used together (each carrying one half of the picture) if 4K is required at 60fps. Maevex is a video
distribution system that saves deployment costs by using an existing LAN. As opposed to IPTV systems, where the content is selected at the viewing screen, Maevex is suitable for centrally controlled applications such as digital signage. Miranda Technologies debuted its SME-1901 module for streaming media. This can handle a wide range of IP monitoring applications with a combination of high-density and high-quality H.264 video and AAC audio encoding. “It’s much less expensive to use IP than SDI,” explained Miranda’s David Cohen. “People can use standard IT equipment rather than dedicated hardware.” Haivision had a convincing demonstration of its live video distribution technology: it was streaming live HD content from its Learning Lounge seminars at the Amsterdam Holiday Inn to its stand on the IBC showfloor. The 1.5Mb HEVC stream was travelling via the hotel and RAI networks – both of which have unpredictable levels of traffic – and the public internet. The live stream used Haivision’s SRT technology (Secure Reliable Transport – currently in beta), which detects real-time network performance and makes endpoint adjustments to optimise video quality and performance. “HEVC squeezes the most
from the network – greater bandwidth efficiencies and video quality – while SRT tames the transport of that content,” said Peter Maag, chief marketing officer.
the new HLI-ET2 Ethernet Module. Main Stations can connect directly or through a LAN using standard IT switches. Linking HelixNet Main Stations together creates a network that pools the channel resources of each individual station. Main Stations can dynamically discover each other, so HelixNet users can share multiple digital partyline channels, plus programme inputs and any two-wire or four-wire interfaces in a network distributed system. A new HLI-FBS Fiber Module is also available for linking stations over long distances. A few days before IBC, Audinate announced that it had signed up the 100th OEM partner for its Dante networking protocol – and a number of these partners were exhibiting solutions at the show, including Studio Technologies, SSL and
services and network-wide synchronisation for OMNEO traffic, and can be configured for fully redundant operation to ensure network reliability and stability. ARNI allows the creation of media networks that can support multiple devices.
The interface will be
available in two versions – ARNI-S (which supports up to 450 devices in a single subnet) and ARNI-E (enterprise version, up to 10,000 devices across multiple subnets). “It seamlessly ties installations together around the world,” commented Bosch’s Ralph Strader.
Riedel Communications and
Studer announced a joint development: a highly scalable audio routing system offering I/O capacities in excess of 10,000 x 10,000 inputs and outputs, which can integrate directly with the Riedel MediorNet system over Studer’s new proprietary A-Link digital interface. This development has been realised by the companies’ jointly developed A-Link interface cards for MediorNet and for Studer Vista and OnAir DSP engines. A-Link is a point- to-point topology similar to, but much faster than, MADI. It has a potential capacity of 1,500 channels per

multiple locations running audio and video presentations wirelessly from smart devices without the need to install any third-party software (see Products, page 60). Also on show was a new near-seamless LCD videowall flat panel – the FHD461-X. The panel’s depth of just 3in – said to be shallower than other panels in the 46in category – makes it suited for space- limited installations, signage in museums, universities, corporate spaces, broadcast sets and retail environments, as well as monitoring applications such as security and surveillance. Bezel width is 5.4mm – the narrowest bezel- to-bezel width of any 46in SNB panel. The panel is compatible with Christie JumpStart, and Christie Interactivity Kit – a fully modular multitouch interactive solution specifically designed for tiled videowalls. A first on the eyevis stand
was the company’s new narrow-pitch LED videowall modules. With a pixel pitch of 1.5mm and 2mm, these are intended for use in large- screen indoor public information displays. These high-resolution modules are suitable for large-screen representations of detailed computer graphics and dynamic video sources for professional use. eyevis says that the LEDs
Yamaha. CEO Lee Ellison told us that manufacturers are turning to Dante because it is being requested by their customers. He added that Dante delivered 3.5 million channels of audio last year, and that there would soon be more than 300 Dante-based products on the market. Dante is the media
transport technology of Bosch’s OMNEO IP-based platform. At IBC, intercom manufacturer RTS launched ARNI (Audio Routed Network Interface) – its latest OMNEO- compatible product, following the launch of RTS+OMNEO in the spring. ARNI provides network
connection.
A single MediorNet 2U box fitted with six A-Link cards can deliver a matrix of 4,608 x 4,608 inputs and outputs, connected to A-Link cards in Studer’s SCore Live DSP systems using optical cables. Studer has entered into a
distribution agreement with Riedel, and so will supply complete systems including consoles and routers.
OTHER TECHNOLOGIES Christie marked its 10th year at IBC with a number of new and recent products. The show saw the European launch of the Brio content sharing system, which works across
offer perfect visibility of content even in bright ambient light conditions, for instance in showrooms with incidental daylight. This is due to a brightness of up to 2,000cd/sqm (on the 1.5mm model), 16-bit colour depth and a refresh rate of 2,500Hz. Calibration also guarantees long-term stability of brightness and colour representation. The extremely high viewing angle of up to 180° also makes them suitable for broadcasters. Genelec launched the latest additions to SAM (Smart Active Monitor) range, the 1237A and 1238A. These are three-way monitors that can automatically adapt to their environment by tuning the frequency response to compensate for acoustical room influences, as well as achieving perfect alignment of levels at the listening position. They can be either free standing or flush-mounted. A powerful new RAM L rack- mount amplifier can be attached to the loudspeaker cabinet when the monitor is free standing.
