Abstract:
The present invention relates to a method of and a device for decoding a set of encoded frames at a first resolution (SD) so as to produce a set of output frames at a lower resolution (QCIF). Said device comprises: a partial decoding unit (DECp) for producing a first residual error field at a second resolution lower than the first one and a second residual error field at a third resolution lower than the first one based on the encoded frame; —a first predicting unit (PRED1) for producing a first motion-compensated field based on the first residual error field, on a first reference field (Fix1) and on a second reference field (Fix2); a first adder for combining the first residual error field with the first motioncompensated field so as to obtain a next first reference field (Fiy1); —a second predicting unit (PRED2) for producing a second motion-compensated field based on the second residual error field, on the first reference field and on the second reference field; a second adder for combining the second residual error field with the second motioncompensated field so as to obtain a next second reference field (Fiy2), the next second reference field corresponding to an output frame.
