摘要： Systems and methods are described herein for displaying subjects of a portion of content and searching for content related to a particular subject in the content. Media data of content is analyzed during playback, and a number of action signatures are identified. Each action signature is associated with a particular subject within the content. The action signature is stored, along with a timestamp corresponding to a playback position at which the action signature begins, in association with an identifier of the particular subject. Upon receiving a command, icons representing each of a number of action signatures at or near the current playback position are displayed. Upon receiving user selection of an icon corresponding to a particular signature, a portion of the content corresponding to the action signature is played back or a search interface is displayed including autocomplete suggestions related to the subject of the signature.

摘要： A method of delivering media content, where a streaming server provides a media content to a streaming client. The media content includes multiple media tracks. A first group of entities is specified for the media content. Each entity in the first group of entities is a media track, an item, or a child group of entities. A first data structure is populated to specify one or more arrays of entity identifiers for the first group of entities. Each array of entity identifiers has one or more identifiers of the entities in the first group. Each array of entity identifiers is associated with one reference type that describes the entities identified by the array of entity identifiers. The first data structure is provided to the streaming client, which provides entities of the first group from the media content for playback according to the first data structure.

摘要： A system is provided for publishing a disparate live media output stream manifest that includes one or more media segments corresponding to key events. A play time of pre-produced media asset metadata is converted to a reference time of a reference clock based on normalized event metadata. The normalized event metadata references time is provided by the reference clock and a plurality of play events from a live playout and production system. Start and end messages for publishing the normalized event metadata are transmitted each time a pre-produced media asset is started and stopped during a playout in a disparate live media output stream. The normalized event metadata is published based on conversion of timestamps for one or more key events to the reference time of the reference clock.

摘要： At a video content network client, obtain, from a remote targeted feature flag configuration server of the video content network, feature flag overrides associated with the client. Send, from the video content network client, to a remote back-end server of the video content network; the feature flag overrides. At the video content network client, obtain, from the remote back-end server, data to be rendered in accordance with an updated feature flag profile including both default feature flag values and feature flag values overridden in accordance with the feature flag overrides. Render the data on the video content network client.

摘要： A method for decoding a picture block is disclosed. The decoding method comprises: decoding (10) at least one stream S_diff into decoded data and into one information for identifying a reconstructed reference picture in a decoder picture buffer; reconstructing (12) a special reference picture from at least the identified reconstructed reference picture and from the decoded data; reconstructing (16) the picture block from at least the special reference picture, wherein the at least the special reference picture is not displayed.

摘要： Systems and methods for modifying broadcast interfaces based on detected broadcast events are disclosed. The system can identify a player profile corresponding to an application executing on a broadcast receiver device, and detect a change in a status of an interaction associated with the player profile. The system can generate instructions for the application executing on the broadcast receiver device that causes the application executing on the broadcast receiver device to display a notification based on the change in the status of the interaction. The system can transmit the instructions to the broadcast receiver device to cause the application executing on the broadcast receiver device to display the notification as an overlay to a broadcast received by the broadcast receiver device.

摘要： A system (400) for providing an audio profile for streaming video, includes an audio profile subsystem (433) that receives audio mix data and synchronizes audio data in an audio profile. A streaming service video streaming server (420) receives video data, uncompressed audio data synchronized with audio tracks, and the audio profile. An audio profile server (430) is configured to receive the audio profile and dynamic range compression descriptors to produce audio profile metadata. An audio reproduction system (410) receives audio profile metadata and listening environment parameters to adjust audio parameters based on the audio rendering system characteristics and a listening environment of the audio rendering system. The audio parameters include one or more of equalization, a filter, a rendering delay, and volume.

摘要： Methods, systems, computer readable media, and apparatuses for providing enhanced content are presented. Data including a first program, a first caption stream associated with the first program, and a second caption stream associated with the first program may be received. The second caption stream may be extracted from the data, and a second program may be encoded with the second caption stream. The first program may be transmitted with the first caption stream including first captions and may include first content configured to be played back at a first speed. In response to receiving an instruction to change play back speed, the second program may be transmitted with the second caption stream. The second program may include the first content configured to be played back at a second speed different from the first speed, and the second caption stream may include second captions different from the first captions.

摘要： Embodiments of the present disclosure provide a solution for media processing. A method for media processing comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein each main stream representation (MSR) in the media presentation is associated with an external stream representation (ESR) in the media presentation. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.
