Paper Abstract

We analyze frame rates in low bit rate video coding and show that an optimal frame rate can be theoretically obtained. In order to achieve an optimum balance between coded picture quality and motion smoothness, a frame rate has to be selected which is appropriate to parameters such as coding scheme, property of the video signals and coding bit rate. In this paper, coding distortion measured by mean square error due to quantization is analyzed by modeling video signals, and it is shown that the frame rate can be uniquely optimized. The result of this analysis is compared with the results of computer simulation. In addition, the relation between this analysis and the subjective evaluation is described.
