Abstract: Exemplary embodiments of the present disclosure are related to minimize data usage over a costly or slow communication link. When a user is not watching a video stream, the stream may be terminated preventing any further data usage on a metered data connection. A system may also include a user device and a back-end network with a stream manager service. The stream manager service terminates streaming over a wireless channel by an application of the user device when the user device determines one of inactivity of a user of the user device with the application or navigation on the user device away from the application.

The method includes: storing a still image and a moving image or video corresponding to the still image into a cloud storage; extracting feature points of the still image stored in the cloud storage, and storing the feature points in the cloud storage in a manner which associates the feature points with the still image; when a device obtains a first still image through scanning, extracting feature points from the first still image, comparing and judging whether the extracted feature points match feature points of each still image stored in the cloud storage to determine a second still image whose feature points match the feature points of the first still image; rendering a moving image or video corresponding to the second still image stored in the cloud storage at the position of the first still image.

Abstract: Viewers of a video stream may generate video clips including different portions of the video stream. Popularity measures may be computed for the video clips, for example based on tracked actions associated with the video clips, such as frequency of playing and sharing of the video clips. The popularity measures may be used to select and provide video clips to viewers. Video items may be generated by streamers, such as may include selected portions of video of streamers playing a game. A video item generated by a particular streamer may be displayed to viewers only during times when that particular streamer is participating in an active game session. Viewers of the video item may provide input that allows viewers to receive a live stream of the streamer's active game session that it is being played simultaneously with the display of the video item.

Abstract: 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.

Abstract: A machine detects a set of first control operations and, in response, causes a display screen to present a graphical interface in which a central window suggests first content by presenting a first preview and a first identifier superimposed on the first preview. The machine then detects a second control operation that indicates dismissal of the first content. In response to the second control operation, the machine causes the display screen to present a transition to an interest-improved version of the graphical interface. The transition includes sliding the first preview, the first identifier, a second preview, and a second identifier together in a shared direction and at a shared speed within the central window. The second preview and the second identifier correspond to second content. In the interest-improved version of the graphical interface, the central window suggests the second content by presenting the second preview and the second identifier.

The application of the rotation operation may then be utilized to reverse the stabilized imaging data. Methods and computing systems are also disclosed.

Abstract: Techniques for handing off media content between proximate display devices are provided. Based on a first media player device currently playing media content from a remote media server receiving a request to hand off the media content to a proximate second media player device, the first media player device may send a handoff token to a second media player device to enable the second media player device to play the media content from the remote media server. The handoff token may include an indication of the media content, an indication of a point within a stream of the media content, and/or credentials associated with the user of the first media player device. The second media player device may send the handoff token to the remote media server, which may send the media content to the second media player device based on verifying the information provided in the handoff token.

Abstract: A method for examining a sample by light sheet microscopy includes illuminating a sample surface located in an illumination plane by a light sheet propagating in the illumination plane.

Detection light emanating from the illumination plane is detected.

Abstract: A roaming video experience, in which users continue watching a content item when moving from viewing device to viewing device is enabled herein via Radio Frequency (RF) enabled remote controls and set top boxes. A device identifier from a first RF-enabled set top box is communicated to an active RF-enabled remote control. When a user signals a second RF-enabled set top box, the viewing session parameter set associated with the active RF-enabled remote control is passed to the second RF-enabled set top box. Using the parameter set, the second set top box is enabled to learn the system settings, user preferences, and content item that were used on the first set top box, and provide a continued viewing experience—the roaming video experience—for the user on an associated viewing device.

A request based on the input is transmitted to a server. At the server and based on the request, program listing data is retrieved. A command for controlling the set-top box is identified based on the program listing data. At least one of the program listing data and the identified command is transmitted from the server to the smart speaker. The identified command is transmitted from the smart speaker to the set-top box.

Abstract: In a video delivery context, collection and analysis of viewing data can provide insight into viewer interaction with video and the Internet. The viewing data can be transmitted in a controlled manner to a data repository. The system can selectively target specific viewers/households to obtain viewing data, which can be combined with demographics, anonymized, and encrypted. Embodiments enable precision selection of media opportunities, by determining detailed characteristics associated with broadcasts including movement of audiences and specific viewer behavior, such as visits to websites on the Internet. The effective yield of broadcasts, including promotional spots and advertisements, can be determined and predicted based on concrete data at a level of detail down to individual viewers. Accordingly, embodiments enable improvement of the effectiveness and return on investment for programming, promotional spots, and advertisements.
