Claim 18:
19. The non-transitory computer-readable recording medium of claim 17, wherein the different video unit levels comprise a picture header, wherein a third syntax element associated with the Cb component indicating the deblocking parameter offsets for the variable beta in the picture header is pic_cb_beta_offset_div2 and a third syntax element associated with the Cr component indicating the deblocking parameter offsets for the variable beta in the picture header is pic_cr_beta_offset_div2; and a fourth syntax element associated with the Cb component indicating the deblocking parameter offsets for the variable tC in the picture header is pic_cb_tc_offset_div2 and a fourth syntax element associated with the Cr component indicating the deblocking parameter offsets for the variable tC in the picture header is pic_cr_tc_offset_div2;
wherein pic_cb_beta_offset_div2 and pic_cb_tc_offset_div2 specify deblocking parameter offsets for the variable beta and the variable tC (divided by 2) that are applied to the Cb component for slices associated with the picture header;
wherein pic_cr_beta_offset_div2 and pic_cr_tc_offset_div2 specify deblocking parameter offsets for the variable beta and the variable tC (divided by 2) that are applied to the Cr component for the slices associated with the picture header;
wherein the different video unit levels comprise a slice header, wherein a fifth syntax element associated with the Cb component indicating the deblocking parameter offsets for the variable beta in the slice header is slice_cb_beta_offset_div2 and a fifth syntax element associated with the Cr component indicating the deblocking parameter offsets for the variable beta in the slice header is slice_cr_beta_offset_div2; and a sixth syntax element associated with the Cb component indicating the deblocking parameter offsets for the variable tC in the slice header is slice_cb_tc_offset_div2 and a sixth syntax element associated with the Cr component indicating the deblocking parameter offsets for the variable tC in the slice header is slice_cr_tc_offset_div2;
wherein slice_cb_beta_offset_div2 and slice_cb_tc_offset_div2 specify the deblocking parameter offsets for the variable beta and the variable tC (divided by 2) that are applied to the Cb component for a current slice; and
wherein slice_cr_beta_offset_div2 and slice_cr_tc_offset_div2 specify the deblocking parameter offsets for the variable beta and the variable tC (divided by 2) that are applied to the Cb component for the current slice.
