Abstract

This paper presents an approach that reuses data stored in the frame memory and in the motion estimation (ME) internal buffer to avoid unnecessary memory accesses and redundant ME computations for MPEG video encoders. This work employs a macroblock bitmap table, which can be easily maintained, to locate the reusable data. The experimental results show that the proposed scheme is particularly efficient in low motion video sequences, approximately saving 18% of the frame memory accesses as well as about 16% of the ME computations without any sacrifice in the image quality.
