Abstract:
1. An information processing apparatus for playing back a content recorded on an information recording medium, comprising: a data transform processor performing a substitution process on content member data recorded on the information recording medium, wherein the data transform processor substitutes transform data as substitute data for the content member data in accordance with acquired holding recording position information of the transform data stored in a fix-up table, wherein the data transform processor further successively acquires divisional fix-up tables distributed in member packets of the content recorded on the information recording medium, and acquires, from the divisional fix-up tables, the transform data as the substitute data corresponding to a part of the member data of the content, and the recording position information of the transform data and acquires a type identifier identifying which of information (a) or information (b) is included in the divisional fix-up tables, wherein information (a) relates to the data for substituting the content member data into the transform data and information (b) relates to the data for substituting the content member data into an identification mark for embedding identification information, wherein the data transform processor changes and performs the substitution process based on the type identifier.
