Presentation
can be defined as two possible user agents in the context: Controlling user agent and Receiving user agent.PresentationAvailability
object is associated with available presentation displays and represents the presentation display availability for a presentation request. If the controlling user agent can monitor the list of available presentation displays in the background (without a pending request to start
()
), the PresentationAvailability
object MUST be implemented in a controlling browsing context.PresentationConnection
interface of the Presentation API provides methods and properties for managing a single presentation. Each presentation connection is represented by a PresentationConnection
object. Both the controlling user agent and receiving user agent MUST implement PresentationConnection
.PresentationConnection.send()
method of the PresentationConnection
interface sends either binary or text data between a controlling browsing context and a presenting browsing context.PresentationRequest
object is used to initiate or reconnect to a presentation made by a controlling browsing context. The PresentationRequest
object MUST be implemented in a controlling browsing context provided by a controlling user agent.
