Abstract: A method receives a manifest for video requested by a client device. The manifest including links for different versions of the video for the client device to use to request segments of the different versions of the video based on conditions detected by the client device. A placeholder in the manifest is selected based on a configuration specifying the placeholder as a trigger to insert alternate content into the manifest. The method then selects a metadata payload based on the configuration specifying the placeholder and a source of the metadata payload and dynamically inserts the metadata payload into the manifest at a position based on the placeholder. The metadata payload is added with an identifier from the configuration that identifies the metadata payload to the client device. The manifest is outputted with the metadata payload for use by the client device while playing the video.

Abstract: Techniques for a service provider network to identifying impacts affecting transmission of a live event to multiple client devices are discussed herein. A system can gather data from a variety of sources associated with the service provider network (e.g., a video service, a client device, a social media service, etc.) and identify patterns in network activity and/or user behavior that are indicative of a potential problem to deliver the live event. In some examples, the system can initiate a query for information associated with the potential problem, and output the query results to a model and/or a user interface for review. The system can, in various examples, determine an action to remedy the potential problem.

Abstract: Systems and methods for summarizing captions, configuring playback speed, and rewriting the caption file for a media asset are disclosed. The system determines whether to display the original captions or a summarized version of the captions, which are based on user's language proficiency level, reading pace, and historical data, and can be generated either on-demand or automatically when rewinds and pauses are detected. The caption file which includes the original captions can be rewritten. The system determines whether to stream a caption or a rewritten file to a media device based on user or system selections. In the absence of a caption file, or when the caption file cannot be summarized, the playback speed of the media asset is slowed down to provide additional reading time to the user.

Abstract: An Avatar Engine triggers transmission of an instance of a three-dimensional (3D) mesh model to a target computer device associated with a first user account. The Avatar Engine detects changes in a video stream captured at a source computer device associated with a second user account, the second user account represented by a digital avatar rendered at the target computer device according to the instance of the 3D mesh model received by the target computer device. The Avatar Engine identifies a command based on the detected changes in the video stream captured at the source computer device, the at least one command corresponding to a portion of blendshapes. The Avatar Engine triggers transmission of the identified command to the target computer device associated with the first user account, the target computer device generating a local instantiation of the digital avatar rendered according to the 3D mesh model and the blendshapes.

Abstract: A processing system receives a user-generated media recording, and metadata associated with the user-generated feedback, from a first device. The user-generated media recording is a recording of the public end-user captured during a live media broadcast using a public-user interface on the first device. The metadata includes information linking the user-generated media recording to the live media broadcast. The system stores the user-generated media recording and the first metadata in one or more storage devices, and transmits a version of the user-generated media recording and at least a portion of the first metadata to a private-user interface on a second device. The private-user interface is configured to receive input from a private end-user selecting the version of the user-generated media recording for broadcast during the same live media broadcast during which the user-generated media recording was created.

Abstract: A distribution controller (141) distributes a live video provided from a streamer to a viewer terminal having a comment area, the comment area allowing a predetermined number of comments to be displayed. A receiver (120) receives a comment posted from the viewer terminal during distribution of the live video. A sender (110) sends a comment that the receiver (120) received to the viewer terminal to cause the comment to be added to the comment area in a last-in-first-out manner. An identifier (144) identifies a comment to which the streamer reacted in the live video being distributed by, every time the streamer speaks, comparing a speech text, the speech text being acquired by subjecting speech of the streamer to speech recognition, with respective comments currently being displayed in the comment area. A display controller (145) controls display of the identified comment.
