Focusrite Audio Engineering has pioneered professional audio recording technology spanning more than three decades. Focusrite Pro, the company’s professional and commercial division, meets the demands of recording, education, post-production, live sound, house of worship and broadcast professionals. It consists of RedNet, a fully modular audio-over-IP solution, and the Red range, Focusrite’s flagship multi-format interfaces, along with the heritage ISA range of microphone preamplifiers and analogue signal processors. The solutions have been developed to meet the needs of the most demanding applications through a relentless focus on ease of use, quality and reliability.
AIMS is an industry consortium led by broadcast and ProAV engineers, technologists, visionaries, vendors and business executives dedicated to an open-standards approach that moves broadcast and media companies quickly and profitably from legacy systems to a virtualized, IP-based environment. AIMS’ efforts build upon those of leading standards bodies such as the Video Services Forum (VSF), the Society of Motion Picture and Television Engineers (SMPTE), the European Broadcast Union (EBU), the Advanced Media Workflow Association (AMWA) and the Audio Engineering Society (AES). We don’t compete with these bodies—we seek to foster the good work they have done.
This clear technology roadmap helps broadcasters rapidly deploy flexible IP-based production, storage and distribution capabilities, provided by the industry’s leading infrastructure and software vendors. AIMS is an inclusive, transparent and not-for-profit organization which enables close cooperation between members and leading standards bodies ensuring that broadcasters’ and AV professionals’ business and technical needs are met. Together, we drive a comprehensive, ubiquitous set of IP standards that eliminate fragmentation and maximize interoperability, as well as provide reassurance that today’s decisions do not lead to technological dead ends or proprietary lock-in tomorrow.
While radios already offered several simultaneous audio programs, Digigram chose to propose a codec with high channel density in only 1U. This codec had to manage talk-back channels and commentaries via IP. It had to support remote broadcasting of programs between remote studios and generate multiple WEB radio streams for CDNs. This led to the creation of IQOYA SERV/LINK, an extremely reliable and compact codec.
This new generation codec was the first IP audio codec in the market to offer as many channels in 1U. IQOYA SERV/LINK accommodates Digigram’s professional audio cards and relies on the Fluid IP™ streaming engine developed by the brand. It is available in several versions with different format compatibility: MADI / AES67 / AES / EBU / DANTE / Analog.
Designed to overcome the challenges of touring events and installation applications, LS10 is a plug-and-play Avnu-certified AVB switch that integrates seamlessly within the L-Acoustics ecosystem. LS10 runs out of the box AVB for simplified connectivity, united audio and control distribution, and reliable networking. Users spend less time setting up systems and more time focusing on the strategic goal of creating unforgettable audio experiences.
As a member of the Avnu Alliance, L-Acoustics is committed to the development of a complete ecosystem of interoperable devices using IEEE’s open AVB standards. Benefits are:
• Guaranteed delivery of time sensitive data
• Guaranteed phase accuracy
• Low latency
• Maximized bandwidth usage
• Easy setup
RAVENNA is a solution for real-time distribution of audio and other media content in IP-based network environments. Utilizing standardized network protocols and technologies, RAVENNA can operate in existing network infrastructures and is fully AES67 and SMPTE ST 2110 compliant.
Initially developed to meet the exacting demands of the professional broadcast market, RAVENNA offers the best performance characteristics of any audio-over-IP transport solution on the market today: very low latency, full signal transparency and high reliability. Fields of application include in-house signal distribution for broadcasting houses and other fixed installations; flexible setups at venues and live events; OB van support; inter-studio links across WAN links and production facilities.
Powerful, scalable and reliable, the RAVENNA technology framework is already a high-quality stand-alone solution. It is also currently the easiest and most cost-effective route for manufacturers to offer their clients AES67 compatibility, thus taking a large step forwards in their ability to develop interoperable, standards-agnostic communications and signal transport solutions.
Liaisons with standard organizations and industry alliances (i.e. AES, AIMS, AMWA, SMPTE and others) ensure close alignment of the RAVENNA technology with current industry trends. Consequently, RAVENNA is already compliant with the AES67, SMPTE ST2110-30 and ST2110-31 standards.
Dante: The Networking Standard for the Professional AV Industry.
Dante is the leading AV-over-IP solution in the world, found in over 2000 products from more than 400 manufacturers. Dante replaces point-to-point analog and digital connections with a standard IP network that delivers completely lossless audio, massive channel counts and near infinite signal routing flexibility, all while being incredibly easy to deploy and use.
OCA is an architecture for system control and connection management of media networks. Now standardized as Audio Engineering Society AES70, OCA is capable of working effectively with all kinds of devices from multiple manufacturers, to provide fully interoperable multivendor networks.
OCA is an open, license-free standard available to anyone – the full AES70 specification is available through the AES standards website. Although the OCA Alliance welcomes new members at any time, Alliance membership is not required to use AES70.
OCA does not provide media transport, but can be used in conjunction with any available transport protocol (Dante, AVB, AES67, Cobranet, etc.). OCA protocols operate over standard Ethernet or 802.11 Wi-Fi networks.
OCA is a control protocol standard only, and does not define the programming design or user interfaces of devices or controllers.
OCA is modular, and may be used successfully in all sizes of devices, from small wall controllers to large audio processors and mixers. It can be deployed in subsets. For example, some products may use only OCA’s connection management features, others may use only its audio processing features, while still others may use the entire feature set.
