In some embodiments, a method receives a plurality of viewing policies for a media program. The plurality of viewing policies include an action to perform for the media program and an audience. The action for at least a portion of the plurality of viewing policies is reviewed to determine a first viewing policy that includes the action of sending a base content stream for the media program. The method selects a first audience associated with the base content stream in the first viewing policy and one or more second audiences associated with actions in one or more second viewing policies. An audience definition for the media program defining one or more restrictions on viewing the media program is generated. The one or more restrictions are based on the first audience and the one or more second audiences. Then, the method stores the audience definition for the media program.

The embodiments relate to a method and a technical equipment for implementing the method. The method comprises (210) creating a scene structure for a three-dimensional media content, wherein the scene structure comprises three-dimensional data for objects of the three-dimensional media content; (220) determining dependency information for the objects, which dependency information indicates an external factor on which an object is dependent on; (230) storing a scene description defining the objects and their dependency information into a bitstream structure; (240) and transferring a generated scene description to a renderer.

An example device for retrieving media data, the device comprising: a memory configured to store scene data and image data; and one or more processors implemented in circuitry and configured to: receive data for a bitstream indicating that the bitstream includes one or more overlay images, the overlay images comprising either a single static image to be presented with scene data that remains constant while being presented frame-by-frame with frames of the scene data or an image sequence that repeats with a regular periodicity while being presented frame-by-frame with the frames of the scene data; receive the one or more overlay images from the bitstream; receive the scene data including one or more scene images; and present the scene images and the overlay images.

The present invention provides a digital broadcast receiver capable of executing functions having higher added values. The broadcast receiver receives a broadcast wave of a digital broadcast service, controls an operation including activation and end of an application that is in cooperation with a broadcast program based on application-related information, and selects control relating to reactivation of the application based on a user's operation. If activation of the application is requested after the end of the application, the broadcast receiver controls the reactivation or non-reactivation of the application in accordance with the selection of control by the user.

Automating quality assurance (QA) for standardized content sharing is disclosed. A system includes a shared content receiver, a rule retriever, an augmenting data checker, and a verification transmitter. The shared content receiver is configured to receive shared content and receive, from a source of the shared content, augmenting data that describes one or more characteristics of the shared content in a pre-determined format. The rule retriever is configured to retrieve rules associated with serving the shared content. The augmenting data checker is configured to determine if the augmenting data is compliant according to the retrieved rules. The verification transmitter is configured to transmit an indication of whether the augmenting data is compliant.

Systems and methods for creating trick play streams for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment includes a set of encoding servers that encode source content as a set of streams that are each stored in a separate container file, where the set of streams includes: alternative video streams; an audio stream; and at least one trick play stream. In addition, the trick play stream is encoded at a lower frame rate than the frame rates of the alternative video streams, and each frame of the trick play stream is a picture encoded without reference to another picture in the trick play stream. In addition, the trick play stream is stored in a container file including a trick play index having entries that include a timecode and a location of a frame in the track play stream.
