Abstract

This work deals with a new coding method for transmitting TV signals at 15 Mbit/s. The coding scheme is based upon sub-band decomposition by Pseudo-QMF filtering and motion compensation. In that context we have studied the influence on the overall system of various strategies in the motion compensation block. More precisely, in the case of a motion compensation by block matching, the influence of overlapping between the blocks has been first considered. A new non-linear post processing scheme of the displacement vector is also presented which smoothed pretty well the vector field and reduced significantly the vector coding bit rate. Finally various methods of vector coding have been designed and compared.
