Control is performed over a period of a given number N of frames, wherein the first frame of the period is encoded in intraframe mode and the second frame is encoded in interframe or intraframe mode to produce a desired set throughput Bsou for said N frames, on the basis of an initial throughput Bpre resulting from a preanalysis (47, 48, 49, 50, 51) of the N frames with a control increment qpre calculated during the previous period. The method is suitable for digital VCR recording. |
