The invention relates to a method for transmitting a stream of images in unscrambled mode, which comprises the transformation (108) of the images from the stream of images in unscrambled mode by means of a secret reversal transform in order to obtain a stream of transformed images which is encoded and transmitted in place of the stream of images in unscrambled mode, said secret reversal transform transforming each image of a series of images in unscrambled mode: by identically swapping the position of pixels of each image of the series of images in unscrambled mode, and/or by identically modifying pixel colors of each image of the succession of images in unscrambled mode, such that the transformation performed on each image in unscrambled mode is immediately perceptible to a human being when the transformed image is displayed on a screen without the reversal transform having been applied in advance. |
