Abstract: Methods for delivering application content signaling information may include a generating a metadata fragment for application content items of an application to be acquired by a receiver device, adding to the metadata fragment a first set of attributes indicating that rendering of a linear service or a group of linear services is performed by a media player embedded in the application, and transmitting the metadata fragment to the receiver device. The first set of attributes may include an application launch page or launch file indicator for the application, and/or an indication of required capabilities for rendering the application and associated application content items. The first set of attributes may include a start time and an end time for at least one distribution window for the application, and the at least one distribution window may be associated with information about auxiliary application content delivered during the at least one distribution window.
