Abstract
A method comprises receiving content from at least one source, processing the content to identify an object in the content, assigning an identifier to the object based on the processing, permitting viewer selection of the object identifier, and providing additional information for presentation to a viewer of the content responsive to viewer selection of the object identifier. The content in some embodiments comprises live video from at least one live video source. For example, the content may comprise at least a portion of a panoramic video comprising a combination of multiple live videos from respective ones of a plurality of video sources. The panoramic video may be digitally cropped and scaled before a resulting version of the content is provided for presentation to the viewer. A plurality of different digitally cropped and scaled versions of the content from the panoramic video can be generated and made available to the viewer.
