Abstract
A novel method to reduce the external memory needed by an MPEG-2 HDTV decoder architecture is presented and discussed. The total amount of m emory is reduced from 96 to 32 Mbits preserving a good picture quality . Furthermore the approach chosen maintains a low hardware complexity and increases of less than 5%, in 0.35 mu m technology, the total deco der silicon area with respect to the standard de coder.
