Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to select and manipulate objects within a scene, and to modify an object by adding or removing accessories from the object or otherwise customizing the object according to the user's preferences or desires. The RVE system may also provide an interface or interfaces via which the user can obtain additional information for the object, customize the object, be given a price or price(s) for the object as customized, and purchase the object as specified if desired.

Abstract: A real-time video targeting (RVT) system may leverage network-based computation resources and services, available 2D or 3D model data, and available viewer information to dynamically personalize content of, or add personalized content to, video for particular viewers or viewer groups. When playing back pre-recorded video to viewers, at least some objects or other content in at least some of the scenes of the video may be replaced with objects or content targeted at particular viewers or groups according to profiles or preferences of the viewers or groups. Since the video is being rendered and streamed to different viewers or groups in real-time by the network-based computation resources and services, any given scene of a video may be modified and viewed in many different ways by different viewers or groups based on the particular viewers' or groups' profiles.

Abstract: A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to discover, select, explore, and manipulate objects within the modeled worlds used to generate video content. The RVE system may implement methods that allow users to view and explore in more detail the features, components, and/or accessories of selected objects that are being manipulated and explored. The RVE system may also implement methods that allow users to interact with interfaces of selected objects or interfaces of components of selected objects.

Abstract: Architectures and techniques are described to rent electronic books. In particular, a content provider can rent electronic books to individuals for a specified rental term. The individuals may have the option to modify the rental term for an electronic book. The rental term for a particular electronic book may be modified by extending the rental term of the particular electronic book or decreasing the rental term of the particular electronic book. Individuals may also convert the rental of an electronic book to a purchase and a purchase of an electronic book to a rental. In order to rent the electronic books to individuals, the content provider may acquire permission from the publishers of the electronic books. In some cases, the content provider may acquire a pool of time-bound rentable licenses from the publishers to allocate to individuals renting electronic books from the content provider.

Abstract: A user viewing a presentation of media content can obtain related supplemental content through the same or a different interface, on the same or a different device. A listener or other such component can attempt to detect information about the media, such as tags present in the media, the occurrence of songs or people in the media, and other such information. The detected information can be analyzed to attempt to identify one or more aspects of the media. The identified aspects can be used to attempt to locate supplemental content that is related to the media content and potentially of interest to the user. The interest of the user can be based upon historical user data, preferences, or other such information. The user can be notified of supplemental content on a primary display, and can access the supplemental content on a secondary display, on the same or a separate device.

Abstract: Some implementations include displaying media content items on a home screen of a computing device. A display order for a list of media content items may be determined based, at least in part, on a predicted likelihood that an individual one of the plurality of media content items will be selected. A home screen of a user interface may be displayed, according to the determined display order, with a list of a plurality of media content items that are available to the computing device.
