    Abstract: Video format conversion among digital TV systems using a new extendible inverse DCT is developed. Based on the conventional inverse DCT, an extendible inverse DCT equation is given to provide the rational ratio of interpolation. The proposed extendible inverse DCT is backward compatible to the conventional IDCT which is widely used in digital video compression standards such as MPEG. Experimental results demonstrate the preservation of the edge sharpness and continuity at image interpolation. A recursive algorithm with an arbitrary length for the extendible inverse DCT is also proposed. The algorithm is particularly suitable for VLSI implementation using array processing
