Abstract
A video image data decoding apparatus includes a pair of buffer memories for storing decoded intra coded picture data or forward prediction coded picture data, a switch circuit for selecting either the decoded intra coded picture data or forward prediction coded picture data to be sequentially stored in the pair of buffer memories, and a generating circuit utilizing picture data stored in one of the pair of buffer memories for generating picture data to be stored into another buffer memory and also utilizing picture data stored in one buffer memory for generating picture data to be newly stored again into the same buffer memory. The generating circuit performs motion compensation by utilizing picture data stored in one buffer memory for generating picture data to be stored into another buffer memory.
