Abstract (en)
[origin: WO2004008766A1] The invention relates to a method for transmitting additional data within a video data transmission between a transmitter and a receiver according to the prioritized pixel transmission method. The video data consist of individual pixel groups, and each pixel group has a position value within an image array and has at least one pixel value. The minimum size of the image array is defined by the height h and width b of a video image, given in pixels. The invention is characterized in that, during the transmission of the additional data, position values are used that do not occur in the individual video data but are assigned to an offset area of the image array instead.
