Open Control Architecture
AES standard for scalable control-protocol architecture for professional 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.
AES70 is an open standard that may be used freely, without licenses, fees, or organization memberships.
Applicability
AES70 is intended to support media networks that combine devices from diverse manufacturers. Targeted for professional applications, AES70 is suitable for media networks of 2 to 10,000 devices, including networks with mission-critical and/or life-safety roles.
AES70 is for device control, monitoring, and connection management only. It does not provide transport of media program material. However, AES70 is designed to work with virtually any media transport scheme, as the application requires.
AES70's parts are separable and may be used independently.
“Open Control Architecture” enters the record as aES standard for scalable control-protocol architecture for professional media networks. Crown Archives preserves that source wording while asking what Control, Architecture and standard can confirm, complicate or overturn.
Why this record matters
“Open Control Architecture” is worth following because a concise public description often conceals a longer documentary argument. Here, Control, Architecture and standard provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q17155529. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
- Historic place names
- Jurisdictional context
- Routes into maps and plans
Contemporary maps, plans, listed-building records, estate papers and the responsible local or national archive.
Three-step research path
- Establish the record: confirm the title “Open Control Architecture”, its source revision and the description used here.
- Expand the search: follow Open Control Architecture primary sources, Open Control Architecture archive and Control research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
