Abstract
The present invention relates generally to digital watermarking and steganographic encoding. One claimed method recites a method including: obtaining video or image data, the video or image data comprising information steganographically hidden in data representing perceptual portions of the video or image data; analyzing the video or image data to obtain the hidden information, the information comprising data associated with suitability for viewing of the video or image data for a particular demographic; comparing the data to predetermined information; and based at least on said act of comparing, determining whether to render the video or image data for display. Other combinations are provided and claimed as well.

5. A method comprising:
-
providing video or image data as an input to a controller in response to video or image data being transmitted to a data receiver from a data transmitter, the video or image data representing content for display, the video or image data having been encoded with a steganographic marking integrated within the video or image data through alterations to data representing the video or image data, the steganographic marking including a content classification for the video or image data; decoding the steganographic marking from the video or image data to obtain the content classification; comparing the content classification to stored classification information identifying classes of video or image data which are not to be displayed; and providing the video or image data for display in accordance with a result of said act of comparing. - View Dependent Claims (6)

7. A method of encoding video or image material with content appropriateness information comprising:
-
determining an appropriateness indication for video or image material; encoding steganographic information within one or more picture elements of the video or image material by altering data representing the one or more picture elements, and information representing the appropriateness information, the information being for use by a video or image display device including a detector or reader to obtain the information encoded within the video or image material, the device further including a controller to control display or rendering of the video or image material in response to the obtained appropriateness information. - View Dependent Claims (8)
