The Presentation can be defined as two possible user agents in the context: Controlling user agent and Receiving user agent.

In controlling browsing context, the Presentation interface provides a mechanism to override the browser default behavior of launching presentation to external screen. In receiving browsing context, Presentation interface provides the access to the available presentation connections.


Presentation.defaultRequest (en-US)

In a controlling user agent, the defaultRequest attribute MUST return the default presentation request if any, null otherwise. In a receiving browsing context, it MUST return null.

Presentation.receiver (en-US)

In a receiving user agent, the receiver attribute MUST return the PresentationReceiver instance associated with the receiving browsing context and created by the receiving user agent when the receiving browsing context is created.
