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 generating a directory table identifying one or more LLS tables to be broadcast and sending the directory table in a broadcast stream of the one or more LLS tables. In various embodiments, broadcast service signaling may include calculating a cyclic redundancy check (CRC) code for, generating a hash value for, and/or applying a digital signature to one or more LLS tables in a broadcast stream.

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.

Abstract: Systems and methods adapted for providing heterogeneous media services in communication systems, such as using transport layer security deferral and/or medium redirect, are disclosed. In operation according to embodiments, heterogeneous media services may be facilitated by obtaining, by a hybrid broadcast receiver of a receiver device, a computer parsable object comprising information regarding content segment availability and access, wherein the hybrid broadcast receiver is adapted to obtain content via both broadcast and broadband connections for a streaming client of the receiver device. The hybrid broadcast receiver of embodiments may further operate to evaluate the computer parsable object for one or more content segment entries indicating transport layer security is to be invoked with respect to a connection used for obtaining one or more content segments and to overwrite the one or more content segment entries preventing the transport layer security from being invoked by the streaming client.
