A method for multimedia content delivery using HTTP adaptive streaming, comprising sending requests for media objects from an end terminal (203, 203') to a delivery server of a content delivery network, further comprising: - sending an indication within a request for media objects, from the end terminal (203, 203') to the delivery server, of a port number at which unidirectional streaming of media objects can be received in the end terminal (203, 203'), - sending requests for media objects to the delivery server and receiving responses from the delivery server by an adaptive streaming client using HTTP adaptive streaming implemented in the end terminal (203, 203'), - receiving the requested media objects at the indicated port number from a unidirectional streamer of the delivery server through a unidirectional transport protocol used by the adaptive streaming client, - determining by the delivery server, based on evaluation criteria, a pacing rate at which the requested media objects are sent from the unidirectional streamer, wherein the evaluation criteria applied by the delivery server to determine the pacing rate comprises the following evaluation criteria: - evaluation criteria based on device capabilities of the end terminal (203, 203') sent by the adaptive streaming client, within the request for media objects, and - evaluation criteria based on measured network parameters; - buffering together by the delivery server all the requested media objects to be delivered to the same indicated port number; - applying by the delivery server the determined pacing rate to deliver the buffered media objects to the adaptive streaming client from the unidirectional streamer using the unidirectional transport protocol. - sending an indication within a request for media objects, from the end terminal (203, 203') to the delivery server, of a port number at which unidirectional streaming of media objects can be received in the end terminal (203, 203'), - sending requests for media objects to the delivery server and receiving responses from the delivery server by an adaptive streaming client using HTTP adaptive streaming implemented in the end terminal (203, 203'), - receiving the requested media objects at the indicated port number from a unidirectional streamer of the delivery server through a unidirectional transport protocol used by the adaptive streaming client, - determining by the delivery server, based on evaluation criteria, a pacing rate at which the requested media objects are sent from the unidirectional streamer, wherein the evaluation criteria applied by the delivery server to determine the pacing rate comprises the following evaluation criteria: - evaluation criteria based on device capabilities of the end terminal (203, 203') sent by the adaptive streaming client, within the request for media objects, and - evaluation criteria based on measured network parameters; - evaluation criteria based on device capabilities of the end terminal (203, 203') sent by the adaptive streaming client, within the request for media objects, and - evaluation criteria based on measured network parameters; - buffering together by the delivery server all the requested media objects to be delivered to the same indicated port number; - applying by the delivery server the determined pacing rate to deliver the buffered media objects to the adaptive streaming client from the unidirectional streamer using the unidirectional transport protocol.
