1. A system comprising:
a decoder configurable to:
decode a plurality of coefficient values for an adaptive loop filter from a bit stream without decoding a coefficient value for a center position in the adaptive loop filter and without decoding any information for the coefficient value for the center position; and
generate an image by applying the adaptive loop filter to a pixel value associated with the image using the plurality of coefficient values; and
a display coupled to the decoder and configurable to display the image.
