Claim 4:
5. An apparatus for decoding image data, comprising:
a processor configured to:
reconstruct, from an encoded bitstream, an image including multiple color planes, comprising:
decoding, from the encoded bitstream, residual data of at least a first color plane and a second color plane of the multiple color planes; and
reconstructing the at least the first color plane and the second color plane of the multiple color planes;

determine a length of a first deblocking filter for the first color plane of the image, wherein the first deblocking filter comprises a first vertical filter applied vertically across horizontal block boundaries and a first horizontal filter applied horizontally across vertical block boundaries, and the first vertical filter is different from the first horizontal filter;
determine a length of a second deblocking filter for the second color plane of the image, wherein the second deblocking filter comprises a second vertical filter and a second horizontal filter, the second vertical filter and the second horizontal filter share a single filter level, and the length of the second deblocking filter is different from the length of the first deblocking filter;
apply the first deblocking filter to a portion of the first color plane of the reconstructed image; and
apply the second deblocking filter to a portion of the second color plane of the reconstructed image.
