+ * This remapping class is needed because {@link VideoProfile} has more fine grain levels of video
+ * states as apposed to Transactional video states (defined in  {@link CallAttributes.CallType}.
+ * To be more specific, there are 3 video states (rx, tx, and bi-directional).
+ * {@link CallAttributes.CallType} only has 2 states (audio and video).
+ *
+ * The reason why Transactional calls have fewer states is due to the fact that the framework is
+ * only used by VoIP apps and Telecom only cares to know if the call is audio or video.
+ *
+ * Calls that are backed by a {@link android.telecom.ConnectionService} have the ability to be
+ * managed calls (non-VoIP) and Dialer needs more fine grain video states to update the UI. Thus,
+ * {@link VideoProfile} is used for {@link android.telecom.ConnectionService} backed calls.
