A host computer connected over a wide area network system to a client computer interleaves N groups of parity protected packets in order to recover from single or multiple error events of length T. Each of the N groups of data are comprised of M data packets plus one parity packer generated by the modulo-2 sum of data in like positions of the data packets within the group. An error event of length T affects only one packer in each of the N groups, allowing recovery of the lost data, assuming that N or less packets in succession are lost.

1. A method for delivering a stream of digital data packets from a data source to a data destination, the method comprising:obtaining the stream of data packets from the data source; segregating the stream of data packets into a pre-determined number N of pre-reorganized groups, each pre-reorganized group containing a predetermined number M of data packets; including a parity packet with each pre-reorganized group, each parity packet containing information sufficient to enable recreation of a damaged data packet within the group; reorganizing the packets in the pre-determined number N of pre-reorganized groups into M+1 post-reorganized groups, each post-reorganized group containing N packets, no two of which are contained in any single pre-reorganized group; and delivering the post-reorganized groups to the data destination.
