Sampling functions are used to reconstruct an analog signal from a set of sampled values obtained by digitizing the signal in the field of multimedia communications such as audio processing, image processing, and so on. However, conventional sampling functions are not useful for reconstructing television signals with high-speed processing, because they are not compactly supported. This paper proposes practical new sampling functions which are compactly supported.
