Abstract

A method and apparatus for receiving media content in a communications network. A node in the network receives a sequence of fragments from a media stream. The node also receives fragment data relating to each fragment, the fragment data comprising any of an indicator that the fragment comprises key data relating to the media stream and an indication of when a next fragment comprising key data appears in the sequence. If the node determines that any fragments in thesequence are missing, it uses the fragment data to prioritize which missing fragments are required, and sends a request to a further node requesting the missing fragment having the highest priority.
