Abstract: Systems, devices, media, and methods are presented for identifying emerging viewing patterns for visual media such as still images and videos. Emerging viewing patterns are identified by identifying visual tags for visual media viewed by users, selecting a subset of the tags by applying a taxonomy-based filter, generating pattern candidates from the subset, evaluating consumption metrics for each of the generated patterns, and ranking the generated pattern candidates responsive to the consumption metrics to identify emerging viewing patterns for the users.

Abstract: Implementations generally provide simulated audience reactions to performers on camera. In some implementations, a method includes receiving a video of a target user from a target client device. The method further includes providing the video to a plurality of audience client devices. The method further includes receiving raw audience feedback from the plurality of audience client devices. The method further includes providing simulated audience feedback to the target client device based on one or more predetermined audience feedback policies, wherein the target client device provides the simulated audience feedback to the target user.

Abstract: Systems, devices and automated process allow automatic replacement of advertisements or other content in previously-broadcast television programs. A content management system or the like operating on a digital network receives indicia from playback devices that have encountered identified advertisements that are stored in digital video recorders or that are otherwise contained within previously-broadcast television programs. The encounters are recorded in a database for subsequent analysis. If desired, the previously-broadcast advertisements may be replaced with more relevant or engaging advertisements prior to playback to the viewer, thereby allowing a fresher, more relevant and more engaging experience for the viewer.

Abstract: The present invention relates to a method and system for data streaming in a network between one or more data sources and one or more user interfaces, i.e. client devices, and at least one computing platform, i.e. a server, acting as a mediator. The multiple video data streams are integrated by the server into one video signal following the rules established for the layout. The layout comprises multiple fields, said fields containing video data and/or data related to the video. The client devices can react to the video signal by sending requests to the server so that the layout of the video signal can be adapted. The server processes such requests and transmits control signals to the data sources so that the operation modus of the video data sources can be changed.

Abstract: A method of processing and delivering video content is disclosed. An embodiment of the method maintains a raw version of a video program at a server system. Before receiving any request to stream the video program from the server to a client device, a prefetching routine is performed on the video program to transcode and segments a leading portion of the video program. Before receiving any request to stream the video program from the server to the client device, the prefetched video segments are stored in cache memory of the server. The server receives a request to stream the video program to the client device. In response to the request, the prefetched video segments are streamed from the cache memory. The prefetching routine is also performed on the video program to transcode and segment a future portion of the video program, resulting in additional prefetched video segments

Abstract: The present invention relates to a method for generating virtual reality representation for a plurality of terminal devices (110, 120). The method comprises: generating location-based data from two sources (210), a first location-based data representing a terminal device (110, 120) specific local pose coordinates and a second location-based data representing photogrammetric coordinates; constructing a terminal device (110, 120) specific coordinate conversion between coordinates; receiving virtual content (230); and generating terminal device (110, 120) specific virtual reality representation (240) by applying the constructed terminal device (110, 120) specific coordinate conversion to the received virtual content. The invention also relates to a system and to a computer program product.

Abstract: Methods and systems are disclosed herein for determining which of two multimedia devices to use to process a multimedia signal. A user may select a multimedia program from an interactive program guide. The first device will determine whether the multimedia specifications of the selected program exceed the capabilities of the first device. If so, the first device will transmit the multimedia signal to the second device without attempting to process it, and instruct the second device to process the signal and output the data obtained therefrom. If not, the first device will process the signal and transmit the multimedia data obtained from the signal to the second device for output.

Abstract: This disclosure covers systems and methods that both transmit a live video stream from a broadcaster device to viewer devices and relay video clips of reactions (by viewers to the live video stream) to the broadcaster device during presentation of the live video stream. In certain embodiments, the disclosed systems and methods facilitate viewers capturing video clips of reactions to a live video stream using a viewer device and, in turn, transmit video clips received from the viewer device to a broadcaster device during broadcast of the live video stream. For instance, in some embodiments, the systems and methods present the video clips of a viewer's reaction to the broadcaster device during a live-video-stream broadcast. Additionally, in some embodiments, the systems and methods present video clips of other viewers' reactions to a viewer device during a live-video-stream broadcast.

Abstract: Implementations disclose leveraging aggregated network statistics for enhancing quality and user experience for live video streaming from mobile devices. A method includes receiving, by a processing device of a client device, a bandwidth parameter corresponding to aggregated network statistics for at least one of a current geographic location of the client device or a current network of the client device, initializing an upload quality parameter of an upload session based on the received bandwidth parameter, the upload session comprising upload of content from the client device, and modifying, by the processing device, the upload quality parameter during the upload session based on updated bandwidth parameters corresponding to aggregated network conditions for at least one of new geographic locations of the client device or new networks of the client device, the upload quality parameter being used to control a format of the upload session.
