Abstract: A method of transporting media data includes, by a file-based protocol sending unit of a source device, receiving a stream of data comprising Segments of media data from a segmenter of the source device that forms the Segments, each of the Segments comprising a respective individually retrievable file associated with a unique uniform resource locator (URL), determining locations of media delivery events (MDEs) in the stream of media data, wherein the MDEs include data for at least a portion of one of the Segments, determining one or more transmission time requirements for the MDEs representing times at which the MDEs are to be sent to a client device, and providing the MDEs and data representing the transmission time requirements to a physical layer sending unit of the source device according to available delivery slots for the physical layer sending unit.

Abstract: An example device for retrieving media data includes a streaming client and a media presentation application configured in one or more processors implemented in circuitry. The streaming client is configured to determine a start time for an event message corresponding to an interactivity window during which one or more application-specific interactivity events can occur during presentation of media data, the application-specific interactivity events comprising times during which a user of the device can interact with the presented media data, determine an end time for the event message corresponding to the interactivity window, receive data representative of at least one of the application-specific interactivity events during the interactivity window corresponding to the event message, and forward the data representative of the at least one of the application-specific interactivity events to the media presentation application.

Abstract: In one example, a device for retrieving media data includes a memory configured to store media data including advertisement content and main media data, and one or more processors implemented in circuitry and configured to: send advertisement information to an advertisement server device; in response to sending the advertisement information, receive the advertisement content from the advertisement server; retrieve the main media data; and provision the advertisement content to the main media data. The device may further include a coded picture buffer (CPB) and a video decoder that retrieves encoded video data from the CPB for decoding. The one or more processors may provision the advertisement content to the main media content by sending both the advertisement content and the main media content to the CPB.

Abstract: An example device for retrieving media data includes a middleware unit configured to receive a first initialization segment of a broadcast stream of media data, receive a second initialization segment of the broadcast stream of media data, and determine whether initialization information of the second initialization segment is different than initialization information of the first initialization segment. When the second initialization segment includes different initialization information, the middleware unit sends an indication to a media application that media playback is to be reinitialized using the initialization information of the second initialization segment. Otherwise, if the initialization information is the same, the middleware unit sends media data of the broadcast stream received following the second initialization segment to the media application without sending the indication to the media application that the media playback is to be reinitialized.
