Abstract:
1. A method of decoding video data, the method comprising: decoding a first syntax element in a picture layer parameter set defined to indicate whether deblocking filter parameters are present in both the picture layer parameter set and a slice header, wherein the picture layer parameter set is associated with at least one picture of the video data, and the slice header is associated with a current video slice included in the at least one picture of the video data; in the case that the first syntax element indicates that deblocking filter parameters are present in both the picture layer parameter set and the slice header: decoding a second syntax element in the slice header defined to indicate whether to use a first set of deblocking filter parameters included in the picture layer parameter set or a second set of deblocking filter parameters included in the slice header to define a deblocking filter applied to the current video slice and defining the deblocking filter applied to the current video slice according to the indicated one of the first set of deblocking filter parameters or the second set of deblocking filter parameters; in the case that the first syntax element indicates that deblocking filter parameters are present in only one of the picture layer parameter set or the slice header: determining that the second syntax element is not present in the slice header to be decoded and defining the deblocking filter applied to the current video slice according to the deblocking filter parameters that are present in the one of the picture layer parameter set or the slice header; decoding a video block of the current video slice; and applying the defined deblocking filter to the video block of the current video slice.
