ABSTRACT:
A method and apparatus for the automatic censorship of audio-video programming at the receiver in accordance with a viewer-selected censorship mode and multivariate censorship classification data encoded in the audio-video programming signal. The censorship classification data comprise codes that classify the programming for several different subjects and several different censorship levels, including internal video frame coordinates that map the censorship classification data to every region within each frame. Censorship of the audio-video programming is accomplished by automatically obscuring the audio and/or video signal to prevent user discomfort. The viewer perceives this automatic obscuration as a fuzzy vagueness in the audio or video frame, which avoids viewer distraction of discomfort associated with abrupt blanking or programming substitution. The censorship method is readily applicable to cinema performances through the use of cinema film encoding and light-valve obscuration techniques.
