Media container file management

摘要

The invention teaches a media container file comprising media data organized into media source blocks. The media source blocks are partitioned into source symbols that can be processed by a forward error correction (FEC) algorithm for generation of FEC redundancy data. Information of this source block partitioning is included in the file in addition to the source blocks. The container file also comprises meta data providing an association between the media source blocks and the partitioning information. The container file can be employed by a media server in a media session for compiling media data packets to be transmitted to requesting clients without the need of extensive data processing before calculating FEC data.
