Abstract
Digital data comprised of bytes formed of a predetermined number of data bits are encoded for representation in a video frame. Each byte of digital data, or a portion thereof, is represented in a respective region of the video frame by one or more video component levels that are assigned to the region and which correspond to the numerical value of the data bits of the byte or of the portion. The digital data are represented in the video frames in place of a video image or, alternatively, are represented in the same frames in which video images are recorded but in the areas of the frame in which the video image is not ordinarily recorded. Digital data represented in the video frame are decoded from the video component levels assigned to the regions.
