Claim 6:
7. The video coding device of claim 1, wherein the sequence of filters comprises:
a deblocking filter configured to process vertical edges based on a vertical filter strength parameter and horizontal edges based on a horizontal filter strength parameter;
a sample adaptive offset (SAO) filter configured to classify pixels and add offset values to the pixels in accordance with a SAO class parameter; and
an adaptive loop filter configured to use two or more codebooks to indicate one or more filter coefficients in a bitstream,
wherein the one or more primary parameters comprise the SAO class parameter and a SAO type parameter of the SAO filter and the one or more secondary parameters comprise the horizontal filter strength parameter and the vertical strength parameter,
wherein the filter controller is configured to derive the secondary parameters based on the SAP class parameter and/or the SAO type parameter of the SAO filter, and
wherein the filter controller is configured to select the two or more codebooks based on the SAO type parameter.
