Abstract

A method and apparatus for distributing media content in a communications network. At a first node in the network, fragments from a media stream are received and stored in a memory. At least one of the fragments comprises a key data indicator indicating that the fragment comprises key data. In the event that the first node receives a request from a second node in the network for the media stream, it sends to the second node the fragment comprising the key data indicator.
