Device and method for coding video pictures |
| abstract |
The picture quality of an MPEG-encoded video signal is improved considerably by reducing the coefficients after quantization in such a way that the 'Lagrangian cost' D+μR (D is distortion, R is bitrate) is minimal for a given value of the 'Lagrange multiplier' μ. The distortion decreases because the step size is reduced while the bitrate remains equal. |
