Abstract

There is disclosed a method of distributing streamed content in a network, the network having a central server and at least a first node and a second node communicatively coupled to the central server, the streamed content transcoded at the central server as a first transcoded stream and a second transcoded stream, the first transcoded stream and the second transcoded stream being different in at least a bitrate used for transcoding. The method is executable at the central server. The method comprises receiving from a client device, via the network, a request for a portion of the streamed content, the request including an indication of an operational parameter associated with the client device; determining one of the first node and the second node best suited to deliver content to the client device; based on the indication of the operational parameter, determining one of the first transcoded stream and the second transcoded stream best suited for the client device; transmitting to the client device a connection signal, the connection signal including identification of (i) the one of the first node and the second node and (ii) the indication of the one of the of the first transcoded stream and the second transcoded stream.
