Abstract:
System and method for embedding and concealing data within a video signal such that the embedded data is displayed within an unused portion of a video display area such that the embedded data is not visually offensive. In one embodiment the encoding of metadata may be executed by translating or adjusting pixel values of the video signal within the secondary image area, such that the pixel values are repurposed to contain the metadata and wherein the metadata is visually imperceptible.
