Multistage sampling structure conversion of video signals

The work extends multistage implementation of sampling structure conversion to the multidimensional (M-D) case. The issues arising in this task are usefully addressed on the basis of lattice theory. Numerical data supporting the advantages of multistage sampling conversion are presented, and the case of format conversion from the 4/3 to the 16/9 aspect ratio is examined as a study case. The main indication of the present work is that multistage implementation, in the case of systems for sampling structure conversion of video signals, may improve the system characteristics and visual rendition.<
