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 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.
