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.

A receiving device includes a receiving unit configured to receive a segment file constituting a stream of content, a reproducing unit configured to acquire and reproduce the received segment file, and a proxy server unit configured to generate supply availability information including a probability at which the segment file can be supplied to the reproducing unit, in which the proxy server unit generates the supply availability information in response to a request for the segment file from the reproducing unit and supplies the segment file received by the receiving unit to the reproducing unit, and the reproducing unit requests the proxy server unit to transmit a segment file to be reproduced next on the basis of the generated supply availability information. The device can be applied to stream delivery systems.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. XLINKS are staged in successively faster memories of the receiver as ad insertion time approaches such that the entire segment can be viewed holistically and dynamically referenced, where all segment ads are available instantly when stored in SDRAM mode as compared to FLASH or coming from the Cloud. Each parsed item has its own timing to be synchronized with other DASH segment items for a single view experience.

A method of requesting video is provided. The method includes: sending a first video request to a server in response to a video playing instruction, wherein, the server returns a video description information segment and a corresponding complete video according to the first video request, and the video includes a plurality of video segments, and the video description information segment is configured to describe each of the video segments; parsing the video description information segment; and playing the video in segments according to the parsed video description information segment in the process of downloading the video. The present application also provides a computing device and a computer-program product.

Viewing policies are received for a media program being offered via linear programming. The viewing policies are transformed to a linear prioritized list of audiences and respective actions to perform on a per user basis for presentation via the live linear programming. The actions analyzed to determine a base action associated with sending a base content stream for the media program. An audience associated with the base content stream and previous audiences associated with previous actions that have a higher priority in the linear prioritized list than the content stream audience are selected. An audience definition for the media program is generated defining restrictions based on the base audience and the previous audiences. The audience definition is used to determine whether users may view the media program based on characteristics of the users before the media program is available via the live linear programming.

There is included a method and apparatus comprising computer code configured to cause a processor or processors to perform obtaining media content from a first content server, determining whether a manifest indicates presence of a remote element, resolving the remote element, manipulating an updated remote element, and streaming at least one of the media content from the first content server and another media content from a second content server based on manipulating the updated remote element.
