| Abstract: | The bit number allocation strategy of TM5 may cause the coding quality loss and buffer overflow at scene changes, therefore a new algorithm on MPEG2 target bit number allocation is proposed in this paper. Here the influence of scene changes on coding quality is analyzed and an approach to improve the coding performance at scene changes is presented to avoid sharp quality loss of scene change frames. Simulation indicates that this algorithm provides a promising coding quality at scene changes. |
