I assume by *author* you mean the application (web) developer. In this case the
*author* shall have the control in order to give the *user* a better user
experience.

The live broadcast is a single encapsulated stream, MPEG2-TS, so there aren't
seperate files that can be loaded and unloaded. The URL for the MPEG2-TS source
it applies for video/audio/subtitles/etc.

The UA may optimize and notice that something is covering the video and release
the video decoder resources but that is unpredicatable. Having an explicit
control then the *author* can have a clear behaviour form the UA across
platforms.
