1. A system comprising: a media processor including a computer processor and a memory configured to: identify a plurality of categories; receive an input media stream to be displayed on a screen of a display device; construct a mask-area with a geometric shape on a section of the screen of the display device to mask at least one segment of the input media stream; preprocess the input media stream to associate the mask-area of the at least one segment of the input media stream to at least one category from the plurality of categories; and alter the mask-area of the at least one segment of the input media stream based at least in part on the at least one category to create an altered media stream, wherein the media processor comprises a modification layer that includes at least one of a video veil and an audio mask, and the modification layer selectively alters the input media stream to create the altered media stream based on the at least one category, and wherein the media processor identifies the geometric shape drawn on the section of the screen in the at least one segment of the input media stream, the section of the screen contributing to classification of the at least one segment of the input media stream into the at least one category.
