Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable mediums for receiving media data of media content. One apparatus includes processing circuitry that receives a media presentation description (MPD) file and a session-based description (SBD) file. The processing circuitry determines whether the SBD file includes a starting time attribute indicating a starting time of an SBD timeline of a session. The processing circuitry determines the starting time of the SBD timeline based on the SBD file in response to the SBD file including the starting time attribute. The processing circuitry determines the starting time of the SBD timeline based on the MPD file in response to the SBD file not including the starting time attribute.

Using manifest files to determine events in content items

Systems, methods, apparatuses are described for monitoring events in a plurality of different services. A system may monitor manifest files for one or more content items. Manifest files may contain manifest file tags indicating events and insertion opportunities. Events and/or insertion opportunities may be detected, and a switch from one content item to another content item, based on customized user priority preferences, may be caused.

Power aware adaptation for video streaming

Power aware adaptation for a power aware video streaming system may be based on the complexity information conveyed in different ways. A complexity level of a data stream, such as a video data stream, may be selected as a function of a remaining battery power of a wireless transmit/receive unit (WTRU) and on a state set of a plurality of state sets that may be stored and/or managed by the WTRU. These state sets may correspond to, for example, different content sources and/or different complexity estimation algorithms and may be used to select the complexity level of the data stream. The data stream may then be received at the selected complexity level. The complexity level and/or a bitrate of the data stream may be adapted to accommodate, for example, the remaining battery power and/or other circumstances. The adaptation may be customized according to the objectives of use cases.

Cloud-based digital content recorder apparatus and methods

Apparatus and methods for the storage and delivery of content over a network. In one embodiment, the network comprises a managed content distribution network, and the apparatus comprises a “cloud” digital video recorder (cDVR) server which stores, processes and assembles content prior to its delivery in a way that obviates superfluous storage, and gains significant network efficiencies. This approach also facilitates various pre-streaming processing in the video recording (e.g., cDVR) system. One or more content libraries adapted to facilitate cDVR content assembly and access are also disclosed. Secondary content (e.g., promotions, advertisements, etc.) can also be selectively inserted into cDVR content. Various access, business or operational rules and methods implementing the foregoing are also described.

SYSTEMS AND METHODS OF PRESENTING VIDEO OVERLAYS

Systems and methods are provided for relocating an overlay overlapping information in content. The systems and methods may comprise receiving a content item, the content item comprising a video image, and determining a first screen position of an information box (e.g., a score box) in the video image. Determining may be performed with image analysis and/or a machine learning model. The system receives an overlay image (e.g., a channel logo) with a second screen position and determines if the second screen position (e.g., for the logo) overlaps the first screen position (e.g., for the score). In response to determining the second screen position (e.g., of the logo) overlaps the first screen position (e.g., the score), the system modifies the second screen position (e.g., for the logo). Then the system generates for display the overlay image on the video in the modified screen position. The system may not relocate the overlay if the overlay is a high priority.

Receiving device, receiving method, transmitting device, and transmitting method

A receiving device, a receiving method, a transmitting device, and a transmitting method. The receiving device acquires a digital broadcast signal that includes audio-video (AV) content and location information, the location information indicating a source from which application control information for controlling an operation of an application executed in conjunction with a progressing timing of the AV content is obtainable, acquires the application control information from the source indicated by the location information, the application control information including an application ID and a uniform resource locator (URL), obtains, from the URL included in the acquired application control information, control information during a polling period that is defined in accordance with an attribute specified in the acquired application control information, and controls the operation of the application based on the acquired application control information and the obtained control information.
