The Play method tells the server to start sending data via the mechanism specified in Setup. A client MUST NOT issue a Play request until any outstanding Setup requests have been acknowledged as successful.
The Play request positions the normal play time to the beginning of the range specified and delivers stream data until the end of the range is reached. Play requests may be pipelined (queued); a server MUST queue Play requests to be executed in order. That is, a Play request arriving while a previous Play request is still active is delayed until the first has been completed.
