1. A method comprising:
- receiving a media signal having a first display format from a broadcast source wherein the signal comprises video content and embedded data;
decoding the media signal;
displaying the video content in a primary image area of a display device, the primary image area having a second display format; and
displaying simultaneously with the video content a secondary image area on the display device, wherein the secondary image area is outside the primary area and contains the embedded data, wherein the embedded data is concealed within the secondary image area.

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.
