The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). Forward error correction (FEC) redundancy data is pre-calculated for the different source blocks (20; 22; 24) and organized into the container file (1) as different FEC reservoirs (30; 32; 34). The container file (1) also comprises meta data (40; 45) providing an association between the media source blocks (20; 22; 24) and the respective FEC reservoirs (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing and FEC calculation.
