ABSTRACT:
A video apparatus consistent with certain embodiments has a receiver that receives a data stream containing video data and video overlay data, wherein the video data includes a censored region having boundaries. A video plane receives the video data in order to render a video frame for display, the video data including the censored region. A video overlay plane receives the video overlay data in order to render a frame of overlay video data for display. The overlay data has boundaries that overlay the censored region. An alpha plane defines overlay boundaries for the overlay data to determine how much of the overlay video data overlays the censored region when rendering the video frame. The alpha plane defines boundaries that are smaller than the boundaries of the overlay data and larger than the boundaries of the censored region. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
