1. A method of encoding at different levels of quality in a hierarchy, the method comprising:

  • having a signal as input;

    utilizing at least one downsample operation to produce downsampled renditions of the signal at successively lower levels of quality in the hierarchy;

    applying at least one upsample operation to a downsampled rendition of the signal at a first level of quality to produce an upsampled rendition of the signal at a second level of quality in the hierarchy, the second level of quality being higher than the first level of quality, the at least one upsample operation and at least one downsample operation possibly being asymmetrical with respect to each other; and

    producing residual data indicating a difference between the downsampled rendition of the signal at the second level of quality and the upsampled rendition of the signal at the second level of quality.
