1. A method for providing for chunk loss recovery, the method comprising:

  • segmenting data, for transmission to a device, into a plurality of chunks;

    determining a number of chunks, of the plurality of chunks, to be used as a group for creating a recovery chunk, wherein the number of chunks of data is determined by balancing between transmission bandwidth efficiency and transmission reliability;

    creating the recovery chunk from information in each of the number of chunks in the group, wherein the recovery chunk is used to recover a single lost chunk from the group; and

    transmitting the group of chunks and the recovery chunk to the device, wherein the transmission bandwidth efficiency increases as the number of chunks in the group increases, and the transmission reliability decreases as the number of chunks in the group increases.
