Audio media boundary traversal method and apparatus

摘要

A method and data processing system are disclosed for audio media boundary traversal. In one embodiment, the invention transforms a multimedia data stream or file to an audio stream that is understandable to humans and then transforms the audio output back to the original multimedia data stream or file without loss of information. The embodiment processes an input file including both audio or audible, and non-audio components; writes the audio components to an output file; determines locations among the audio components of the non-audio components; transforms the non-audio components to audio components; writes the audio components and the locations of the non-audio components to the output file separately from the audio components; and produces an audio output file. The audio or audible components of the input file remain understandable by humans in the produced output. The embodiment also comprehends interpreting the audio output; transforming the audio sequences back to non-audio components and inserting the non-audio components among the audio components at the written locations; thereby recreating the original input file.
