1. A method of processing video to determine an optimal or near-optimal area of interest of the video to live broadcast, comprising: receiving live video data of a playing area of a sporting event from at least one camera; defining templates for the playing area independently of the live video data, each template defining a plurality of regions of the playing area and linking an interest rating factor to each region of the plurality of regions of the playing area; determining a movement profile for each of a plurality of movable objects identified in the live video data by tracking the plurality of movable objects using at least one tracking technique not based on the live video data, wherein the movement profile defines the corresponding object's movement within the playing area of the sporting event over time, the movement profile comprising a trajectory of the object defined as a plurality of positions of the object within the playing area at a plurality of time points of the sporting event and at least one velocity at a time point of the plurality of time points; determining, at one or more time points of the sporting event, an overall interest-rating for each movable object of the plurality of movable objects based on a correlation between the movement profile of that object and at least one region of at least one template of the templates of the playing area that the movable object is currently positioned in or moving towards at the one or more time points in the sporting event, the overall interest-rating comprising a combination of the interest rating factor linked to the at least one region of the at least one template and at least one additional interest rating factor derived from the movement profile of the movable object, the movement profiles of other movable objects, and contextual factors for the sporting event; identifying, at the one or more time points of the sporting event, a sub-portion of the live video data of the playing area based on an aggregated interesting rating of a sum-total of a portion of the overall interest-ratings of the of movable objects being at least a high threshold value; determining an action to control the at least one camera for selecting an optimal camera of the at least one camera or camera position for the at least one camera; and broadcasting the identified sub-portion of the live video data of the playing area by triggering the action to control the at least one camera.
