Ravenna is a technology for real-time transport of audio and other media data in IP-based network environments, which was introduced to the public on Sep. 10, 2010 at the International Broadcasting Convention in Amsterdam. Ravenna can operate on most existing network infrastructures using standard networking technology. Performance and capacity scale with network performance. Ravenna is designed to match broadcasters' requirements for low latency, full signal transparency and high reliability. Fields of application include (but are not limited to): in-house signal distribution for broadcasting houses and other fixed installations, flexible setups at venues and live events, outside broadcasting support, and inter-studio links across wide area network links and production facilities.

Standard protocols
Ravenna is an IP-based solution. As such it is based on protocol levels at or above layer 3 of the OSI reference model. All protocols and mechanisms used within Ravenna are based on widely deployed and established standards:
Open technology
Ravenna is an open-technology standard without a proprietary licensing policy. A first-draft version of the Ravenna specification is publicly available. The development is jointly executed within the RAVENNA Partner Group under the leadership of ALC NetworX GmbH, Munich. Current Ravenna partners include:
Standardization activities
Ravenna contributes to the standardization efforts within AES SC-02-12-H X192 - High-performance streaming audio-over-IP interoperability. As a result of the X192 Task Group work, the AES67-2013 standard for audio applications of networks - high-performance streaming audio-over-IP interoperability was published on September, 11th, 2013. Ravenna is already compatible with AES67, since all relevant mechanisms, protocols and formats used for synchronization, transport and payload mandated by AES67 are fully supported.
