Claim Text:
1. A method for encoding or decoding a current picture or slice of a video signal, the method comprising the steps of: establishing at least one filter buffer in one or more of a video encoder or a video decoder; buffering a plurality of adaptive filters in the at least one filter buffer, wherein the plurality of adaptive filters are used to perform one or more of motion interpolation, motion estimation, motion compensation, motion estimation interpolation, motion compensation interpolation, motion prediction interpolation or motion prediction of an encoding or decoding step; encoding or decoding the current picture or slice with at least two (2) reference pictures, wherein one or more of the adaptive filters for a first of the at least two reference pictures are signaled independently from at least one of the adaptive filters for at least a second of the at least two reference pictures; and based on the encoding or decoding of the current picture or slice, tracking a usage count of each filter of the plurality of filters; and based on the tracking, managing the at least one filter buffer, wherein the managing step comprises the step of:
