Abstract
An example method includes decoding a plurality of filter coefficients of a cross-component adaptive loop filter, wherein decoding a particular filter coefficient of the plurality of filter coefficients comprises: decoding, from an encoded video bitstream, a syntax element specifying an exponent value that represents a log base 2 of an absolute value of the particular filter coefficient as two raised to the power of the exponent value; and determining a value of the particular filter coefficient based on the exponent value; reconstructing samples of a block of video data; and cross-component adaptive loop filtering, based on the plurality of filter coefficients, the block of video data.
