Abstract

A low-bandwidth Integer Motion Estimation (IME) module is proposed for MPEG-2 to H.264 transcoding. Based on bandwidth reduction method proposed in Ref. 1), a ping-pang memory control scheme combined with Partial Sum of Absolute Differences (SAD) Variable Block Size Motion Estimation (VBSME) architecture are realized. Experiment results show bandwidth of the proposed architecture is 70.6% of H.264 regular IME (Level C+ scheme, 2 Macro Block (MB) stitched vertically), while the on-chip memory size is 11.7% of that.
