Abstract: In the method an indefinite number of audio tracks are stored separately for each video film, in order to be played back in sync with the video in the Internet. Hence, a video can be stored in any number of languages, and at any time the language can be changed in real time during the playback of the video without having to reload the video. This method works well for different sources, for example, different video platforms, on which the same video is offered, because the platforms all use the same stored audio tracks. This feature and the small size of the audio tracks reduce the upload and memory requirement by about 90%, as compared to the conventional method of having to provide in each case a single video, including the audio/language track, for each individual language.
