Abstract
A content encoder for encoding content into a source image for display on a display device includes inputs for receiving data representing content to be encoded into the source image; a processor arranged to encode the content into a sequence of display frames each including the source image, the content encoded as a time varying two-dimensional pattern of luminosity modulations of portions of the source image to form a sequence of encoded images of the source image; and outputs arranged to output the sequence of encoded images to the display device.
