Abstract
One embodiment concerns a method for generating a media fragment request for requesting fragments of an encoded media stream stored on a server device, the method being implemented by a client device storing a structure representative of fragments of the media stream previously received and stored on the client device. The structure includes first and second types of addressing information associated with fragments already received. The method for generating a media fragment request includes forming a media fragment request to obtain missing media data corresponding to a new fragment of the media stream, the media fragment request specifying at least one piece of addressing information of the first type and at least one addressing information of the second type, wherein the first type of addressing information is spatial or temporal information and wherein the second type of addressing information is byte position information within the media stream.
