ABSTRACT:
A method for hierarchically block coding a packet stream includes the steps of appending a packet error correction code to each packet in the packet stream and appending a block error correction code to successive blocks of packets in the packet stream to form a hierarchically error correction coded packet stream. This packet stream is then transmitted through a communications channel. Errors are corrected in each block of packets in response to each block error correction code and errors are corrected in each packet in each block in response to each packet error correction code.
