Abstract
Adaptive video zoom is provided by a method of providing a video content item for viewing by one or more viewers. The method includes identifying one or more objects within the video content item. The method further includes, for each identified object, assigning a searchable descriptor for the object, creating a time stamp indicating one or more time periods within the video content item during which the object occurs, and creating a bounding window defining a region of the video content item within which the object occurs. The searchable descriptor, time stamp, and bounding window are then packaged into metadata associated with the video content item. The method further includes delivering the video content item and the metadata associated with the video content item to a client computing device.
