Authoring multimedia in the CMIF environment

We present the user interface to the CMIF authoring environment for constructing and playing multimedia presentations. Within the environment an author constructs a presentation in terms of its structure and additional synchronization constraints, from which the actual timing information is derived. The CMIF authoring environment presents three main views of a multimedia presentation: a hierarchy view for manipulating and viewing a presentations hierarchical structure; a channel view for managing logical resources and specifying and viewing precise timing constraints; and a player for playing the presentation
