scope:

This Recommendation specifies the architecture and functional components needed for the provisioning of packaged IPTV application (widget) service. Widgets are lightweight applications, provided with a simple and easily accessible GUI, which commonly provide a single functionality (e.g., calendars, feed aggregators, etc.) and might stay persistently exhibited. The widget service definition relies on the interoperability and harmonization provided by IPTV multimedia application frameworks (MAFRs) [ITU-T H.760]. The scope of the recommendation comprises the definition of the IPTV packaged application model and the definition of essential service components such as service discovery, packaging, metadata and security.

The target terminal device types range from the basic model as specified in [ITU-T H.721] to fullfledged terminal devices, which are defined in [ITU-T H.722].
