Open Control Architecture

The Open Control Architecture (OCA) is a communications protocol architecture for control, monitoring, and connection management of networked audio and video devices. Such networks are referred to as 'media networks'. The Open Control Architecture (OCA) is a communications protocol architecture for control, monitoring, and connection management of networked audio and video devices. Such networks are referred to as 'media networks'. The official specification of OCA is the Audio Engineering Society (AES) standard known as AES70-2015, or just AES70. This document will use the newer term 'AES70' to refer to the standard and the architecture it specifies.
