A remote stream is the stream that a user other than the current user of Video Service published. When listening for onPublishedStreamChange events you can identify local stream events by the isLocal property being set to false.
Rendering
Within the onPublishedStreamChange event is a participant object. This object contains the MediaStream that is being published. You can add participant.mediaStream to a video element in your html. There will be separate events for each remote stream that is is published/unpublished.
