This paper proposes an efficient inter/intra mode decision algorithm for H.264/AVC video downscaling transcoding to reduce computation cost while maintaining high coding performance. The experimental result shows that the proposed algorithm achieves a reduction of 42% total re-encoding time, with negligible performance distortion, when compared with complex cascaded pixel domain transcoding (CCPDT). The proposed algorithm is also compared with the simple mapping method (SMM), and the result demonstrates that the improvement in coding performance is remarkable.
