Abstract:
1. A computer implemented method for generating a multimedia presentation based on data retrieved from a first read-only storage medium and data retrieved from a second rewritable storage medium, wherein the data on the first storage medium are stored as files structured in a first directory tree, and the data stored on the second storage medium are stored as files structured in a second directory tree, wherein the first storage medium has a first and a second identification label attached, the method comprising the steps of: in a first determining step, determining that a first branch of the second directory tree corresponds to the first identification label and a second branch of the second directory tree corresponds to the second identification label, wherein the second branch is a subbranch of said first branch; in a second determining step, determining whether for a first file from the first directory tree, a second file from the second directory tree exists that has a file name matching the name of the first file; constructing a logical directory tree from the first and second directory tree, wherein the first file from the first directory tree is included if, according to the second determining step, no second file matching the name of the first file exists on the second directory tree, and wherein otherwise the second file from the second direction tree is included instead of the first file; retrieving data from the first and second storage medium according to the logical directory tree; and generating a multimedia presentation based on said retrieved data, wherein said data from the first and the second storage medium are seamlessly integrated.
