Abstract
The formatting of a video image frame (10) having a first aspect ratio to yield an image frame having a different aspect ratio is facilitated by establishing a pan and scan pixel coordinate (P) within the image that defines an image capture window for formatting purposes. A predictor (22) determines the pan and scan pixel coordinate by examining the image frame to determine the location therein of the most pertinent activity. The predictor (22) determines the location of the most pertinent activity by examining at least one of: video data, audio data, and other data such as closed captioning information.
