Abstract:
1. A method of transmitting information, comprising the steps of: generating, in a transmission apparatus, a sequence of one or more packets for carrying file data of one of a plurality of programs, each program carrying data of one or more files to be used by a recipient node in a similar fashion each packet of the sequence being transferred from source node to recipient node in whole or as plural segments in a signal; and transmitting, by the transmission apparatus, the sequence of packets, wherein the sequence of packets comprises: (a) a header of a first packet of the sequence of packets, the header including a program identifier field containing a program identifier which uniquely identifies the program of the sequence of packets, and (b) a payload containing one or more data triplets, each data triplet including a tag, a length and a value field, the tag uniquely identifying the value in the value field and the length indicating an offset in data words to an immediately following data triplet, a length of zero indicating that no data triplet follows, the value fields of the sequence of data triplets containing information for uniquely correlating file data in each packet of the sequence to a respective file of one of the best-effort programs, wherein the sequence of packets contains two or more packets, wherein the first packet of the sequence has a payload with no data of the file and wherein each other packet of the sequence has a payload with data of the file.
