Abstract (en)

[origin: WO2005022530A1] The invention relates to a method for playing back a media file in a playback unit, comprising the retrieval of the executable instructions contained in the media file by the playback unit, the execution of the instructions for decoding and/or decompressing a media data flow that is stored in the media file in a coded or compressed manner by an execution device of the playback unit and playback of the media data flow by means of the instructions executed in the execution device. The invention also relates to a method for generating a media file, comprising coding and/or compressing a media data flow with the aid of a processing algorithm, definition of a processing algorithm that is complementary to the processing algorithm as instructions that are executed by the playback unit and assembling the media file with a first area for receiving the coded and/or compressed media data flow and at least a second area for receiving the executable instructions.
