Abstract

This paper presents a model of interlaced video. The model uses the assumption that the whole scene, which is captured by a camera, is moving at a constant speed. Within this model, the Fourier transform of the interlaced video signal is analyzed for various modes used in picture coding, such as intrafield, intraframe, interfield (with motion compensation), and interframe (with and without motion compensation) processing. The main spectral components of the signal are identified. The analysis yields new insight into the nature of the components. This insight is useful in the design of video processing systems, which is illustrated by various applications
