    Abstract: A device for processing media content obtains data from a box within a file conforming to a file format for a video codec, the box comprising a syntax structure that includes the data, the file being associated with the media content and the media content being coded according to the video codec; and determines, based on the data obtained from the box, whether to accept or reject the media content associated with the file. A device for generating media content generates data in a box within a file conforming to a file format, the box comprising a syntax structure that includes the data, the file being associated with the media content, wherein the data is for use in determining whether a client is to accept or reject the media content associated with the file; and outputs the file.

    Abstract: Various embodiments for delivering application content signaling information to a receiver device may include a server 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 including a list of other linear services that use the application content items described by the metadata fragment, and transmitting the metadata fragment to the receiver device. The first set of attributes further 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 its associated one or more application content items. The first set of attributes further may include a start time and an end time for at least one distribution window for the application, the distribution window may be associated with information about auxiliary application content delivered during the distribution window.

    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.
