The compressed data of an auxiliary stream of data, defining an auxiliary image, is decoded on the fly during the display of each main image into which this auxiliary image is to be inset. The data is decoded to deliver luminance and chrominance values intended to be mixed with the luminance and chrominance values of the counterpart pixels of the main image being displayed, in succession during each decoding of the auxiliary image and for the successive pixels of this auxiliary image.
