  Abstract

The concept of MPEG-2 transcoding is related to the scaling the bit rate of the previously encoded MPEG bitstream. We proposed a new rate control algorithm that outperforms existing methods and showed the performance by a computer simulation. A rate-quatization model is developed based on a priori knowledge from the given bitstream at macroblock level. The model is independent of the picture coding type, because it is designed in the DCT domain. To increase the accuracy of the model, the activity measurement is considered.
By the simulation, the proposed transcoding showed the better result than that of recoding by TM5. We also concluded that MPEG-2 scalable profile is not suitable for the bit rate conversion application.
