MEDIA CONTAINER FILE MANAGEMENT

摘要

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. The container file can also be employed in a post-session repair procedure.
