DETERMINATION OF CODING PARAMETERS FOR A HYBRID CODING SCHEME

摘要

The invention relates to a method for determining a sequence of values for a coding parameter of a hybrid coding scheme for every frame of a frame sequence for use in the coding of the frame sequence by means of the hybrid coding scheme. The hybrid coding scheme allows to determine resulting distortions and compression rates for the frames of the frame sequence if the frame sequence is completely coded and if a genuine partial sequence of the frame sequence is incompletely coded, in such a manner that a genuine subset of the set of distortions and compression rates such as they can be obtained by coding using possible sequences of predetermined values for the coding parameter for every frame. Estimated distortions and compression rates for frames of the frame sequence are determined (202) and the sequence of values for the coding parameter of the hybrid coding scheme is determined based on the resulting and estimated distortions and compression rates previously determined.
