Abstract: A voice-enabled device and a display device may be utilized to determine items in video output by the display device. A frame of a video stream associated with the video may be utilized to determine a representation of a candidate object. A stream identifier and a timestamp associated with the candidate object in the video stream may be determined. The stream identifier, the timestamp, and an object identifier associated with the candidate object may be stored in a database. A first request to output the video stream via a display device may be received. A second request associated with the video stream may be received while the video stream is being output by the display device. The second request may be determined to be associated with the representation of the candidate object. The object identifier may be caused to be visually displayed via the display device.

Abstract: Systems, methods, and computer-readable media are disclosed for synchronization and presentation of multiple 3D content streams. Example methods may include determining a first content stream of 3D content to send to a user device, where movement of the user device causes presentation of different portions of the 3D content at the user device, and determining a first position of the user device. Some methods may include causing presentation of a first portion of the first content stream at the user device, where the first portion corresponds to the first position, determining a second content stream of 3D content, where movement of the user device causes presentation of different portions of the 3D content at the user device, and causing presentation of a second portion of the second content stream at the user device, where the second portion corresponds to the first position of the user device.
