Claim:
An information processing device comprising: a processor that acquires image data encoded in increments of precincts that are groups of lines including sub-bands that generate one line worth of lowest band components of the image data; creating means for creating header information; dividing means for dividing precincts of encoded image data into a plurality of payloads for a corresponding plurality of packets, at every predetermined data amount determined beforehand; packetizing means for forming the plurality of packets by adding said header information created by said creating means to each of said plurality of payloads obtained by said precincts of encoded image data having been divided by said dividing means; and flag setting means for setting, as to a head packet of the packets generated by said packetizing means of which a payload is a head of a precinct of the encoded image data, a head flag indicating said head packet, included in the header information, and setting, as to a final packet of which a payload is an end of the precinct of the encoded image data, an end flag indicating said final packet, included in the header information, wherein said head flag has only one of two fixed values, and the end flag has only one of two fixed values.
