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: Systems, methods, and devices enable a receiver device to determine completeness of low level signaling (LLS) tables received via broadcast transmissions. In various embodiments, broadcast service signaling may include determining whether a received LLS table is a directory table identifying each of a complete set of LLS tables, parsing the directory table, determining whether the directory table is confirmed based at least in part on a digital signature in the directory table, determining whether a complete set of LLS tables is received based at least in part on the identification of each of the complete set of LLS tables in the directory table, and determining available services based at least in part on the complete set of LLS tables before an expiration a repetition time period after receiving the directory table.

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.
