Claim:
1. A method of coding video data comprising: selecting a filter to apply near a boundary of a first portion of the video data that separates the first portion of the video data from a second portion of the video data, wherein the filter comprises a plurality of filter coefficients; determining at least one of the plurality of filter coefficients for which the video data will not be available to be filtered; based on the determination of the at least one of the plurality of filter coefficients for which the video data will not be available to be filtered, determining a partial filter, wherein the partial filter does not include the at least one of the plurality of filter coefficients for which the video data will not be available to be filtered; renormalizing the plurality of filter coefficients included within the partial filter in accordance with either a first renormalization algorithm or a second renormalization algorithm, wherein the first renormalization algorithm comprises: wherein the second renormalization algorithm comprises adding one or more of the at least one of the plurality of filter coefficients of the full filter for which video data will not be available to be filtered to the one or more of the plurality of filter coefficients of the partial filter; and applying the renormalized partial filter near the boundary of the first portion of the video data to generate a filtered first portion of the video data.
