The system and the method of doing the data division which optimizes the rate distortion in video encoding making use of the parametric rate being warped model

摘要

Being simple, and efficient ranking video coded technique parametric rate it is warped and it discloses the system and the method of having (RD) making use of the model. The video coded system can possess the data divided encoder and the data divided decoder which optimize the rate distortion. The RD-DP encoder which is generalized is adapted the divided point at the block unit, with that, coded efficiency of the based layer bitstream, without explicit transmission improves greatly, retrenches bandwidth rather with that. Furthermore, the parametric rate being warped model obstructs the fact that a state where based layer is not divided sufficiently occurs even with in case of non parametric rate skew curve, the parametric model is renewed, in order to take same period, simultaneously with the encoder and the decoder.
