This paper describes a method to hide side-panel signals on conventional NTSC receivers, which can be used in a middle format (equal area) widening method. Side-panel signals, which are rearranged to top and bottom areas of the image, are transformed to two kinds of components: low-energy component and high-energy component. The high-energy component is physically hidden in the normal vertical overscan of existing NTSC receivers, and the low-energy component is rearranged to the top and bottom areas. Computer simulation results indicated that the proposed method can reduce the artifacts on NTSC receivers.
