The Open Control Architecture (OCA) is a communications protocol architecture for control and monitoring of networked audio and video devices. Such networks are referred to as "media networks". OCA is a free, open public standard. It is intended to support networks that combine devices from diverse manufacturers. Targeted for professional applications, OCA is suitable for media networks of 2 to 10,000 devices, including networks with mission-critical and/or life-safety roles. OCA is for device control and monitoring only. It does not provide transport of media program material. However, OCA is designed to work with various media transport schemes, as the application requires. OCA is termed an "architecture" because it provides the basis for definition of multiple control protocols. These protocols all share a common design model, but vary in signalling detail, depending on the form of the underlying data transport mechanism. An OCA application will use whichever OCA protocol is appropriate for the communications method available. == Background == OCA was developed by the OCA Alliance, beginning in 2011. It was based on a control protocol named OCP, which was created by Bosch Communications Systems in 2009 and 2010. OCP was in turn based on an embryonic control protocol standard named AES-24 〔 AES24-1-1999 (w2004): AES standard for sound system control - Application protocol for controlling and monitoring audio devices via digital data networks - Part 1: Principles, formats, and basic procedures. 2004: Audio Engineering Society, New York. 〕 〔 AES24-2-tu (w2004): PROPOSED DRAFT AES standard for sound system control - application protocol for controlling and monitoring audio devices via digital data networks - Part 2, data types, constants, and class structure (for Trial Use). 2004: Audio Engineering Society, New York. 〕 developed by the Audio Engineering Society in the 1990s. The OCA Alliance is a trade association whose mission is to develop and enhance the definition of OCA, and to promote OCA's adoption throughout the professional media systems industry. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Open Control Architecture」の詳細全文を読む スポンサード リンク
