Abstract
A system and method have been provided for achieving simultaneous media playout in a network including a server and a plurality of clients. The method comprises: from a server, supplying a media stream to clients at a first bitrate (R1); determining the network delivery requirement; and, in response to the network delivery requirements, modifying the supply of the media stream. Determining the network delivery requirements includes determining either the buffering capacities of the clients, or the media streaming disruptions. To determine the buffering capacities of the dents, a first minimum client buffering capacity (C1) is determined by polling the clients for their respective buffering capacities, and selecting the first minimum buffering capacity (C1) to be equal to the client with the smallest buffering capacity.
