Abstract:
Disclosed embodiments include a method and an apparatus for digital content transmission that comprise: (a) partitioning the digital content into a plurality of sequential segments; (b) selecting a plurality of transmission time instants for each of the sequential segments as a function of their order; (c) generating a plurality of linear combinations of the plurality of sequential segments during the plurality of transmission time instants resulting in a plurality of linearly combined coded segments; and (c) transmitting the plurality of linearly combined coded segments from a server to a plurality of clients. In particular embodiments, the method and apparatus further comprise performing error correction based on an implicit error correction (IEC) method that employs the redundancy present in the linearly combined coded segments to perform error correction at the client side without extra bandwidth cost.
