Abstract: Method and system for playing back ancillary data associated with a video stream. At playback, a video stream and an audio stream containing encoded non-audio ancillary data associated with the video stream are received. The audio stream is decoded on a basis of a predefined decoding scheme in order to extract therefrom the non-audio ancillary data associated with the video stream. The video stream and its associated non-audio ancillary data are then both output for playback. This method of playback enables a non-linear editing application that supports only video and audio data to receive, preserve, display to a user for editing purposes, and transmit unsupported non-audio ancillary data, since the latter is in the form of an audio stream.
