Abstract
A recovery chunk is generated based on information found in each chunk in a group of chunks. For example, the group of chunks includes three chunks of which information in the three chunks is used to generate a recovery chunk. The recovery chunk is then used to recover a single lost chunk in the group of chunks. The three chunks and the recovery chunk are sent to a receiver over a network. If one of the three chunks is lost, the recovery chunk is used to generate the lost chunk. The recovery chunk is used to recover a single lost chunk, however, the recovery chunk is not used to recover more than one lost chunk in the group. The number of chunks is also dynamically adjusted based on chunk loss at a receiver. This adjustment is based on the bandwidth used and reliability desired.
