Abstract

Apparatus and methods for multicasting blocks of data to a plurality of receivers, the blocks including a first block and a second block, the first block comprising k,&gE;1 data packets, the transmission of the first block comprising an initial transmission of the k,data packets and h,&gE;repair packets and one or more subsequent transmissions of additional repair packets in response to repair requests, wherein any k,of the data packets and repair packets provide sufficient information to recover the k,data packets; and multicasting a second block comprising k,&gE;1 data packets, the transmission of the second block comprising an initial transmission of the k,data packets and h,&gE;repair packets, wherein any k,of the data packets and the repair packets of the second block provide sufficient information to recover the k,data packets of the second block and either or both k,and h,differ from k,and h,, respectively.
