Abstract
A video decoder can be configured to set each block-level syntax element of a plurality of block-level syntax elements to a value indicating that an adaptive loop filter is enabled for an associated component of the video data in response to determining that a slice-level syntax element is set to a value indicating that values for the plurality of block-level syntax elements are inferred.
