4.1.12. setRemoteDescription

The setRemoteDescription method instructs the PeerConnection to apply the supplied session description as the desired remote configuration. As in setLocalDescription, the type field of the description indicates how it should be processed.

This API changes the local media state; among other things, it sets up local resources for sending and encoding media.

If (1) setLocalDescription was previously called with an offer, (2) setRemoteDescription is called with an answer (provisional or final), (3) the media directions are compatible, and (4) media is available to send, this will result in the starting of media transmission.
