One or more frames within a video are segmented and classified according to information type. At least a portion of the information in the one or more frames is determined to be obscured. In response to this determination, information from audio data and the unobscured portion of the one or more frames is extracted. Using this extracted information, a set of replacement data is generated, according to the information type, for the obscured information in the one or more frames. The set of replacement data and the unobscured portion of the one or more frames is merged into one or more composite frames. These composite frames are displayed to a user.
