http://dev.w3.org/html5/spec/video.html#timed-track

The specification should specify different kinds of actual content files 
(timed  or untimed track files) that may be associated with a media resource:
A textual representation of the content
An audio representation of the content (See SL-1, SL-2 in [1])
A video representation of the content
Non-synchronized alternatives that can be rendered as replacements for the
original rendered content (DAC-5 in [1])

SUGGEST:
http://dev.w3.org/html5/spec/video.html#dom-track-src

The src attribute points to an additional timed or untimed textual, audio or
video representation of the media content that the user or user agent may
display.

The rendering of the alternative / replacement content is defined by the actual
track format and the user agent; for example:
Non-synchronized alternatives may be rendered as replacements for the original
rendered content
A additional video representation of the original content may be rendered over
the original content, or positioning in all parts of the screen. (CC-5 in [1])
