| Abstract(in English) | Today, the wide deployment of MPEG-2 video for digital video applications and the expected use of H.264 video creates a strong need for video transcoding between these formats. One of key problems in MPEG-2 to H.264 video transcoding is complexity reduction. In this paper, we propose an encoding mode decision scheme for MPEG-2 to H.264 video transcoding to enable low complexity transcoding. The proposed transcoding approach reuses the incoming motion vector information, coding mode and DCT coefficients of MEPG-2 bitstream. Experimental results show that the proposed schemes can sigificantly reduce the computational complexity of the transcoder while keeping the similar rate-distortion performance. |
