Abstract

This paper describes an algorithm for frequency scanning (FS) of DCT coefficients which has been submitted to MPEG (Motion Picture Experts Group) in contrast to the well-known block scanning technique. It presents the principle and the coding method of the new scanning technique. With respect to coding the scanned coefficients, an entropy coding method, called modified universal variable length coding (MUVLC), which is derived from the already published UVLC technique, is employed. In the test model (TM) system of MPEG the coding efficiency of both MUVLC and the MPEG VLC was compared. The results showed that the MUVLC technique gives higher coding efficiency and more flexibility in a broadcast environment.
