Paper Abstract

This paper presents a coding mode decision algorithm for MPEG-2 spatial transcoding. The optimization for coding mode and quantization scale are formulated in an operational rate distortion sense and solved by Lagarange multiplier method. The experimental results show that the proposed transcoder with optimized coding mode and quantizer can achieve better quality and lower bit rate than those obtained using cascaded transcoder or MPEG-2 TM5 encoder.
