/**
* NormalMediaPresentationEvent is a JMF event generated when the
* normal media components of a service are presented.
* Media presentation is considered as normal when explicitly selected
* service components (by a dedicated API), or implicitly selected service components
* (by the player itself) can be presented to the user. Media presentation is
* considered as "alternative" in any other case, especially when it is caused
* by one of the reasons described in {@link AlternativeMediaPresentationReason}.
*
* NormalMediaPresentationEvent notification is generated :
*
When normal media content presentation begins;
* During the presentation of a service, if alternative media content was
* presented and all of that media alternative content is replaced by a
* content which is a normal part of the service concerned;
* During the presentation of a service, if normal media content was being
* presented and an evaluation leads to a new normal media content presentation.
