| Abstract(in English) | In this paper, we focus on the MPEG-2 transcoder to provide the flexible video transmission by converting the compressed video bit streams, and study on the new coding scheme for realizing bit stream scalability by preserving and re-using the differenatial data generated by transcoding process.First, we show problems in the scalability by encodingand decoding process, and propose the scalable coding method by separating and composing of MPEG-2 bit streams.Especially, we aim at the improvement of coding efficiency.we consider the separating and composing algorithm.Next, we point that it is possible to estimate the changing of DCT coefficient block that generated by requantization process, and show the coding algorithm of this changing data by classificating coefficient value and re-constructing method of original DCT block.Last, by simulation experiments, we show that the proposed method prevents the increase of total bit-count by separating process, moreover it brings re-compressing effect.And by cascading the bit stream separating processor.it can easily realize the multi layer scalabirity.we show the effectivensss of proposed scalable coding method. |
