  • Methods and apparatus for packetizing data for transmission through an erasure broadcast channel
    Patent number: 6175944
    Abstract: A system for transmitting data over an erasure channel. A data block is divided into coarse and fine segments. The coarse segment is encoded using an error-correcting encoding process. The fine segment and the encoded coarse segment are combined and divided into packets, and the packets are transmitted over the erasure channel. When the data is received, the coarse segment is decoded. If data packets were lost during transmission, the coarse segment is reconstructed as the received data block. If no packets were lost, the fine segment is combined with the coarse segment and the entire data block as originally transmitted is reconstructed. For large numbers of packets, the system invention can achieve any point within the capacity region of an erasure channel.
