摘要：
Methods and apparatus for embedding and recovering an image for use with video content are disclosed. A disclosed system embeds a real component of a spectral representation of an image into a set of video frames and embeds an imaginary component of the spectral representation of the image into a second set of video frames. The two sets of video frames are combined and broadcast. The disclosed system recovers the real component of the spectral representation of an embedded image from a first set of received video frames and the imaginary component of the spectral representation of an embedded image from a second set of the received video frames.
