[tvcontrol-api] Component Discovery and Selection

mprobst-irt has just created a new issue for 
https://github.com/w3c/tvcontrol-api:

== Component Discovery and Selection ==
There are various ways to discover available channel components and 
also to select them.

The TVProgram interface has languages for audio and subtitles which I 
think refers to EPG data, e.g. languages signalled for components in 
EIT schedule.

-> the current TVProgram interface is missing support for 
accessibility services like audio description.

The MediaStream and its extension has tracks and allows to 
enable/disable them.
The HTML5 media elements have tracks and allow to enable/disable them.

-> Is it clear how both objects interact? Can either be used?
-> See also my other issue on mapping service information to API. It 
should be defined which part of a service information is used to 
populate properties for tracks etc.
-> There should be a defined relation between a component signalled in
 the EPG with tracks retrieved from MediaStream or HTML5 MEs. For 
example the EPG includes information that a program comes with Audio 
Description. When the program is running it should be possible to 
identify the proper audio track.
