1. A method of coding a video signal that contains video data corresponding to an imaged scene, comprising:

  • identifying an object that corresponds to a visual element from the scene, a portion of the scene other than the visual element being a remainder of the scene;

    compressing video data corresponding to the object and compressing a remainder of the video data using an amount of compression that is greater than an amount of compression used to compress the video data for the object so as to produce a high fidelity video component corresponding to the visual element and a low fidelity video component corresponding to the remainder of the scene; and

    tracking the object using the high fidelity video component and using tracking information regarding a predicted position of the object in a future frame of the video signal to compress the video data when the future frame arrives.
