Information processing device and method, recording medium, and program

The present invention relates to an information processing apparatus and method, recording medium, and program capable of generating a priority table in a straightforward manner. JPEG 2000 data 151 inputted to a table generation section 114 is held by a JPEG 2000 data reading section 161, and is provided to a JP2 packet information extraction section 162 at a prescribed timing. After the necessary JP2 packet information has been extracted in packet form, this is provided to a priority table editing section 164. Then, at the priority table editing section 164, a priority table with priority values set for all of the JP2 packets is made based on setting information 152 designating priority values for some of the JP2 packets corresponding to the JPEG 2000 data 151 provided by the setting information reading section 163 and is outputted by the priority table output section 165. The present invention can be applied to personal computers.
