Abstract:
1. An information processing device for executing content reproduction processing, comprising: a content reproduction processing unit having a processor that performs data transformation processing for replacing a part of configuration data of input content to be reproduced with transformation data, and executing processing for reproducing the reproduction content; and a parameter generating unit for providing said content reproduction processing unit with a parameter to be applied in said data transformation processing; wherein said content reproduction processing unit has a configuration for obtaining a parameter identifier that is different for each segment set as a sectioning region of reproduction content, and outputting a parameter calculation request to said parameter generating unit; and wherein said parameter generating unit has a configuration for providing said content reproducing processing unit with a parameter corresponding to a segment, in response to the parameter calculation request from said content reproducing processing unit, said transformation data being registered in a fix-up table and including proper content data, and said content reproduction processing unit has a configuration for subjecting fix-up table data including said transformation data to execution of computation processing applying the parameter corresponding to the segment obtained from said parameter generating unit, and for executing restoration processing of data including the transformation data applied as replacement data as to the configuration data of said segment, wherein at least a part of the fix-up table is scattered in packets in the configuration data of the input content, said fix-up table includes the transformation data registered to correspond to replacement data at a predetermined region within the reproduction content.
