The G2 player from Real Networks allows users to specify
which language they prefer, which can be evaluated in a SMIL
document to choose among text or audio tracks. Currently only
one language can be indicated which does not permit choosing,
for example, English spoken audio with Spanish captions.

The Quicktime player permits turning on and off any number of
tracks individually, which can include audio, video, and text.

Examples are available from the Web Access Project at NCAM.

This was included primarily for Internationalization. Captioning,
description languages and signing often times need to be in many languages,
so if the document (i.e. a SMIL document) provides choices for captioning
langauge, etc... the user agent should support the user being able to
select the track of their choice.  I don't know if there are any current
players that support multiple captioning tracks, but SMIL specification
does support the markup to provide multiple tracks.  This checkpoint
therefore is designed to encourage developers to consider
internationalization issues and the effects on disability.  Supporting
multiple languages is an important topic not only within WAI (see
discussions in the Web Content Group), but an important issues throughout
the W3C.
