Abstract
A method for embedding information in a video signal is described. The method comprises receiving () a message () including the information; dividing () the message () in a first message part () and a second message part (); acquiring () a first video frame () and a second video frame () from the video signal, wherein the second video frame () is temporally subsequent to the first video frame (), and the video frames () each include a pre-set number of pixels; and determining () a motion map () associated with the second video frame (), wherein the motion map () indicates a movement of each of the pixels of in the second video frame () compared to the first video frame (). The method further comprises embedding () the first message part () in the pixels of the second video frame () including weighting the first message part () for each pixel of the second video frame () based on the motion map (); and embedding () the second message part () in the pixels of the second video frame () including weighting the second message part () for each pixel of the second video frame () based on an inverse of the motion map (). Furthermore, a graphical encoder () and a system () are described, which are configured to perform such method.
