Abstract
A server system obtains a first video sub-stream comprising a first plurality of images of a scene and obtains a second video sub-stream comprising a second plurality of images of at least a portion of the scene. Images of the second video sub-stream have a higher image resolution than images of the first video sub-stream. The first video sub-stream is transmitted to a client device for display. A selection of a region of interest in the scene is received, wherein the selection is from a first image of the first plurality of images of the first video sub-stream, the first image having a first timestamp. Based on the first timestamp, the server systems locates image data of the selected region of interest from the second plurality of images, and provides the located image data of the selected region of interest to the client device for display.
