Patent ID: 8208559

Claim:
A device for decoding a set of encoded frames at a first resolution so as to produce a set of progressive output frames at a lower resolution an encoded frame comprising an encoded first field interlaced with an encoded second field, said device comprising: a partial decoding unit 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 for producing a first motion-compensated field based on the first residual error field, on a first reference field and on a second reference field a first adder for combining the first residual error field with the first motion-compensated field so as to obtain a next first reference field a second predicting unit 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 motion-compensated field so as to obtain a next second reference field the next second reference field corresponding to an output frame.
