Abstract
A system and method for encoding sound information in image sub-feature sets comprising pixels in a picture or video image. Small differences in intensity of pixels in this image set are not detectable by eyes, but are detectable by scanning devices that measure these intensity differences between closely situated pixels in the sub-feature sets. These encoded numbers are mapped into sound representations allowing for the reproduction of sound.

A system for embedding audio information in image data corresponding to a whole image for display or print, said image data comprising pixels, the system comprising:
- device for characterizing a sub-area in said whole image as a pixel block comprising a predetermined number of pixels, each pixel block including first and second complementary sets of pixels representing respective first and second image sub-feature sets, a first image sub-feature set including pixels comprising whole image content to be displayed or printed;
- and, a second image sub-feature including pixels comprising coded audio information;
- and,
- audio-video transcoding device for associating said second image sub-feature set with units of audio information, said transcoding being performed so that image sub-features in the second set satisfy constraints related to visibility of said whole image.
A method for embedding audio information in image data corresponding to a whole image for display or print, said image data comprising pixels, the method steps comprising:
- characterizing a sub-area in said whole image as a pixel block comprising a predetermined number of pixels, each pixel block including first and second complementary sets of pixels representing respective first and second image sub-feature sets, a first image sub-feature set including pixels comprising whole image content to be displayed or printed;
- and, a second image sub-feature including pixels comprising coded audio information;
- and,
- encoding pixels of said first image sub-feature set with whole image content to be displayed or printed and pixels of said second image sub-feature set with coded audio information, said encoding of said audio data performed such that image sub-features in the second set satisfy constraints related to visibility of said whole image.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for embedding audio information in image data corresponding to a whole image for display or print, said image data comprising pixels, the method steps comprising:
- dividing each of one or more image pixels into first and second complementary sets of pixel components representing respective first and second image sub-feature sets;
- encoding pixels of said first image sub-feature set with whole image content to be displayed or printed and pixels of said second image sub-feature set with coded audio information, said encoding of said audio data performed such that image sub-features in the second set satisfy constraints related to visibility of said whole image.
