RAVENNA is a technology for real-time transport of audio and other media data in IP-based network environments, which has been introduced to the public on Sep. 10th, 2010 at the International Broadcasting Convention in Amsterdam[1][2] . Utilizing standardized network protocols and technologies, RAVENNA can operate on most existing network infrastructures. Performance and capacity are scaling with the capabilities of the underlying network architecture. Primarily targeting the Professional Broadcast Market, RAVENNA is designed to match Broadcaster's requirements for low latency, full signal transparency and high reliability (24/7 operation). 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, OB van support, inter-studio links across WAN links and production facilities.

RAVENNA is an IP-based solution. As such it is based on protocol levels on or above layer 3 of the OSI reference model. All protocols and mechanisms used within RAVENNA are based on widely deployed and established standards:
RAVENNA is an open technology standard without a proprietary licensing policy. A first draft version of the RAVENNA specification[3] is publicly available. The development is jointly executed within the RAVENNA Partner Group under leadership of ALC NetworX GmbH, Munich. Current RAVENNA partners include renowned companies from the Pro-Audio market, such as:
RAVENNA has been presented to the Audio Engineering Society (AES) and European Broadcasting Union (EBU) for potential consideration for standardization. RAVENNA technology is considered to contribute to the standardization efforts within AES SC-02-12-H X192 - High-performance streaming audio-over-IP interoperability.[5]
