METHOD AND APPARATUS FOR RECOVERING A DISPLAY PICTURE SEQUENCE FROM A CODED DIGITAL VIDEO SIGNAL

摘要

A method for recovering a display picture sequence from a coded digital video signal with a variable data rate comprises the steps of decoding the coded digital video signal in order to obtain an intermediate picture sequence (S2), detecting the data rate of the coded digital video signal (S3), and a quantity representative of the amount of motion in the pictures of the intermediate picture sequence (S5, S6), and filtering the intermediate picture sequence (S8) in order to obtain the display picture sequence, wherein a filtering characteristic of the filtering step is defined (S7) on the basis of the detected data rate and the detected motion quantity.
