{*}Components of digital multimedia video{*}
Digital multimedia video generally consists of two major elements; a video track, with an accompanying audio track.
These tracks or components of the video are termed data streams. Although typically there is one data stream for
video and another for audio, it is also possible for more than two data streams to be present. An example of this
is the commentary feature found on many DVDs, where the second of two audio data streams can be chosen to
accompany the video stream.
