Abstract
In certain embodiments, a method for generating fees using a receiving device, involves distributing censored video from a distributor video to a receiving device; and uncensoring the censored video using the receiving device upon payment of a fee. The receiving device uses overlay data received from the distributor to uncensor the censored video by overlaying the overlay data over the censored video using a video overlay frame to overlay a video frame containing the censored video data in accordance with boundaries determined by an alpha plane within the receiving device. This abstract should not be considered limiting since embodiments consistent with the present invention may involve more, different or fewer elements.
