1. A method for embedding information in a video signal, the method comprising:
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, the video frames each including a pre-set number of pixels, wherein the second video frame is temporally subsequent to the first video frame;, determining a motion map associated with the second video frame, wherein the motion map indicates a movement of each of the pixels of the second video frame compared to the first video frame;
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.
