Abstract: Aspects of the subject disclosure are directed towards providing feedback to users of multi-user system that has biometric recognition capabilities, so that a user knows whether the system has correctly associated the user with his or her identity. The feedback may include a display of a current camera view, along with visible identity information that is associated with each user in the view. The feedback may include per-user icons (e.g., tiles, thumbnail images and so on) by which a user visually confirms that he or she is correctly recognized. Any misrecognition may be detected via the feedback and corrected. Feedback may convey other information, such as the current interaction state/capabilities of a user.

Abstract: A first video preview corresponding to a first video program is played back. When it is time to transition from playing back the first video preview to playing back a second video preview corresponding to a second video program, the transition is made from playing back the first video preview to playing back the second video preview. The transition can be made by sliding the first video preview off a display while sliding the second video preview onto the display. Additionally, metadata associated with the first video program can be displayed for an amount of time before playback of the first video preview ceases, and metadata associated with the second video program can be displayed for an amount of time after playback of the second video preview begins.

Abstract: User input in the form of image data is received from a user via a natural user interface. A vector difference between an adjustment start position and a current position of the user input is calculated. The vector difference includes a vector position and a vector length. The vector position is compared to stored rail data, and the vector length is compared to a stored threshold length. The rail data describes a plurality of virtual rails associated with an application. Based on the comparisons, the user input is matched to one of the plurality of virtual rails and a notification describing the matching is provided to the application. The application, thereupon, transitions from a first command to a second command corresponding to the matching virtual rail without receiving any explicit termination gesture for the first command from the user.

Abstract: Content gestures are described. In implementations, one or more controls are output to control output of content and for display in a user interface by a computing device. An input is recognized, by the computing device, which was detected using a camera as a gesture to interact with a particular one of the controls to control the output of the content.

Abstract: Systems and methods for video ad delivery using configurable dynamic video ad policies are provided. A system for delivering video ads to a video client may include an ad platform service. The ad platform service may have a media registration module configured to receive input data including a video ad policy and associated metadata and digital video content from a digital video content client. The ad platform service may further include a registration database configured to store input data received from the media registration module. The ad platform service may further include a manifest service and an associated manifest generation engine, wherein the manifest service may be configured to receive an ad manifest request from a video client. In response, the manifest generation engine may be configured to generate a manifest instance based on input data received at the manifest service, the manifest service being configured to send the manifest instance to the video client.

Abstract: A favorite channel list for a media system is generated by observing the viewing, surfing, and recording habits of a user. The viewing habits may include the duration and frequency of viewing a channel. A user's surfing habits, including navigation habits of a guide, the method used for navigation to a channel, and information queries made during a surfing session may be used to determine which channels may be added to a favorites list. When the user has an ability to record a program and view the program later, the user's behavior in selecting programs for recording, and the behaviors of playing back and archiving recorded shows may also be used to identify favorite channels. In some embodiments, the favorites list may be customized for a user or node of a playback system, as well as time of day.

Abstract: Media purchase techniques are described. In an implementation, an indication is received that an item of media was successfully purchased through a single transaction that includes rights for access to the item of media in different forms that are optimized, respectively, for different classes of computing devices. Responsive to the receipt of the indication, the item of media is permitted to be streamed to at least one of the computing devices to enable output of the item of media for playback as the item of media is streamed and storage of the item of media to local storage of the computing device.
