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: 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: In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server device.

Abstract: In one example, a device for retrieving media data includes a memory configured to store an ISO Base Media File Format (ISO BMFF) file including one or more samples including hypertext markup language (HTML) elements defining dynamic web content, and a processing unit implemented in circuitry and configured to: retrieve the ISO BMFF file, extract the HTML elements from the samples of the file, and processing the HTML elements to present the dynamic web content. The HTML elements may include JavaScript elements. The processing unit may also present the dynamic web content in a manner that is synchronized with corresponding media data.

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.

Abstract: An example device includes one or more processors configured to execute a proxy server for a client device including a streaming client. The proxy server is configured to determine that a tuned channel for the client device has changed from a previous channel to a current channel, and, in response to the determination that the tuned channel for the client device has changed from the previous channel to the current channel, deliver media data of the current channel to the streaming client of the client device according to a WebSocket subprotocol without receiving a request from the streaming client for the media data. In this manner, the streaming client can receive media data of the current channel (following a channel change event), without having received a manifest file for the current channel and without sending a request to the proxy server for media data of the current channel.
