Claim 0:
1. A decoder configured to:
receive a bitstream comprising a reference picture, a current picture having a resolution different from the reference picture and including a first block and a second block, a signal indicating that a mode when a reference picture and a current picture have different resolutions is enabled, and information including an index to a set of predetermined values useful for determining a scaling constant;
determine a scaling constant using the information in the bitstream including the index;
determine a scaled prediction block by scaling a prediction block of the reference picture using the scaling constant and by applying a filter determined specifically for the prediction block and not determined for the whole reference picture;
utilize the scaled prediction block to reconstruct the first block; and
reconstruct the second block without using a scaled prediction block of a reference picture.
