Abstract:
Dynamic forward error correction (FEC) setting is discussed in which the network determines a FEC percentage for each video segment of a video streaming service, based on consideration of the transfer length of the video segment and the allocated bandwidth. When the transfer length and allocated bandwidth reflect transmission of less than peak bandwidth, the network will determine a higher FEC percentage that uses the otherwise wasted bandwidth to transmit additional redundancy symbols. The additional redundancy symbols increase the error recovery rate when collisions occur between streaming video reception and page monitoring occasions of other networks in multi-network, multi-subscriber identification module (SIM) mobile devices. A network entity may then transmit the dynamic FEC percentage for each video segment in the file description table (FDT) associated with the video streaming service.
