    1. Topics

       1. ISO/IEC 23008-11 1^st edition

MMT defines a composition layer to enable the authoring and delivery of rich media services. The Composition Information (Cl) is authored using HTML5 and thus exhibits all the Capabilities and tools availablefor HTML5. In addition, MMT CI provides tools to support dynamic media scenes and their delivery over unicast channels, authoring of content for secondary screens, as well as separation of media dynamics from scene setup. This is achieved in a backward compatible manner using a dedicated CI file that is in XML format.
