Title: RE-SAMPLING FILTERS FOR SCALABLE VIDEO CODING
Abstract:
In one embodiment, a method receives a plurality of sample values. The method then determines a filter to determine an up-sampled value for a first layer for a video, wherein the filter has a set of coefficient values of [-1, 3, -9, 47, 31, -10, 4, -1] or [-1, 4, -10, 31, 47, -9, 3, -1] assigned to the filter. The up-sampled value is determined by applying the set of coefficient values of [-1, 3, -9, 47, 31, -10, 4, -1] or [-1, 4, -10, 31, 47, -9, 3, -1] to the plurality of sample values. The method then outputs the up-sampled value for use in coding a second layer of a higher resolution than the first layer. The up-sampled values may be for the 6/16 and -6/16 phase offsets.
