In order to accommodate periodic clustering structures such as the above structure, a conceivable approach is periodic signaling of buffer descriptions. This buffer description specifies the temporal distances or positions of the reference pictures relative to a target picture to be coded or decoded. By so doing, the reference pictures stored in the DPB can be specified. For example, this buffer description is signalled once in the picture parameter set (PPS). This buffer description is then referred to repeatedly in the slice headers of the pictures having the same relative position within a cluster. For example, a buffer description specifying relative positions of {−1, −3} can be used in both P5 to specify {P4, P2} as reference pictures and by P9 to specify {P8, P6} as reference pictures.
The buffer description updating information 523 includes information which specifies the buffer description selected out of the buffer descriptions 515. In the example in FIG. 2, the buffer description BD1 is selected. Additionally, the buffer description updating information 523 includes buffer description modifying information. The buffer description modifying information assigns a picture identifier to a selected buffer element 515A within the selected buffer description 515. Here, the picture identifier is specified either using its elative position or using an identifier unique to the picture. The identifier unique to the picture includes, for example, the picture order count (POC) number. In the example in FIG. 2, the picture P214 identified by its POC number=214 is assigned to the buffer element BE0 within the buffer description BD1. This modification applies only to the current target slice and does not apply to subsequent slices.
In a coded bitstream, reference pictures used for the inter prediction process of prediction units (an N×N block) are identified using reference indexes. All available reference pictures and their associated reference indexes are described in a reference list. When bi-predictive inter prediction is used, two reference lists are used for describing two groups of reference pictures and the associated reference indexes. Smaller reference indexes are represented with fewer bits in the coded bitstream compared to larger reference indexes. Therefore, higher coding efficiency is achieved by assigning smaller reference indexes to frequently used reference pictures.
It is to be noted that “slice” in the above explanation may be replaced by “sub-picture unit (SPU)”. The sub-picture unit includes, for example, a tile, an entropy slice, and a group of blocks constituting a wavefront processing sub-picture partition (Wavefront Parallel Processing (WPP) unit).
first_delta_poc_minus1 indicates an absolute POC difference value between a current picture and the reference picture associated with the buffer element BE[0] in the buffer description BD. first_delta_poc_sign_flag and first_delta_poc define the value of the signed variable BDDeltaPOC[0] as
BDDeltaPOC[0]=(first_delta_poc_minus1+1)*(1−2*first_delta_poc_sign_flag)
first_temporal_id specifies a temporal identifier and is represented by a predetermined number of bits. For example, the predetermined number of bits is indicated earlier in the coded bitstream and is indicated, for example, in the active SPS or the active PPS. first_temporal_id defines the value of the unsigned variable BDTemporalID[0] as
delta_poc_minus1[j] specifies a negative POC distance value from the reference picture associated with the buffer element BE[j] to the reference picture associated with the buffer element BE[j+1] in the buffer description BD. delta_poc_minus1[j] defines the value of the signed variable BDDeltaPOC[j+1] as
BDDeltaPOC[j+1]=BDDeltaPOC[j]−(delta_poc_minus1[j]+1)
temporal_id[j] specifies a temporal identifier and is represented by a predetermined number of bits in a similar way as first_temporal_id. temporal_id[j] defines the value of the unsigned variable BDTemporalID[j+1] as
BDTemporalID[j+1]=temporal_id[j]
Each of the PPSs 302B includes SPS selecting information 321 (sps_select) and a PPS identifier 322 (pps_id). The SPS selecting information 321 (e.g. sps_select=0) indicates the SPS 301B which is referred to. Furthermore, each of the PPSs 302B is identified by the unique PPS identifier 322 (e.g. pps_id=0).
first_delta_poc_minus1[i] indicates an absolute POC difference value between a current picture and the reference picture associated with the buffer element BE[i][0] in the buffer description BD[i]. first_delta_poc_sign_flag[i] and first_delta_poc[i] define the value of the signed variable BDDeltaPOC[i][0] as
BDDeltaPOC[i][0]=(first_delta_poc_minus1[i]+1)*(1−2*first_delta_poc_sign_flag[i])
first_temporal_id[i] specifies a temporal identifier and is represented by bits_for_temporal_id bits. first_temporal_id[i] defines the value of the unsigned variable BDTemporalID[i][0] as
BDTemporalID[i][0]=first_temporal_id[i]
delta_poc_minus1[i][j] indicates an negative POC distance value from the reference picture associated with the buffer element BE[i][j] to the reference picture associated with the buffer element BE[i][j+1] in the buffer description BD[i]. delta_poc_minus1[i][j] defines the value of the signed variable BDDeltaPOC[i][j+1] as
BDDeltaPOC[i][j+1]=BDDeltaPOC[i][j]−(delta_poc_minus1[i][j]+1)
temporal_id[i][j] specifies a temporal identifier and is represented by bits_for_temporal_id bits. temporal_id[i] defines the value of the unsigned variable BDTemporalID[i][j+1] as
delta_poc_minus1 specifies an absolute POC difference value between a current picture and the reference picture to be associated with the buffer element BE[bd_select][be_idx_in_bd_update] in the buffer description BD[bd_select]. first_delta_poc_sign_flag and first_delta_poc define the value of the signed variable BDDeltaPOC[bd_select][be_idx_in_bd_update] as
BDDeltaPOC[bd_select][be_idx_in_bd_update]=(delta_poc_minus1+1)*(1−2*delta_poc_sign_flag)
temporal_id specifies a temporal identifier and is represented by bits_for_temporal_id bits. temporal_id defines the value of the unsigned variable BDTemporalID[bd_select][bd_idx_in_bd_update] as
BDTemporalID[bd_select][be_idx_in_bd_update]=temporal_id
The semantics of the syntax elements of the reference list description defining information ref_pic_list_modification_flag_l0, ref_pic_list_modification_flag_l1, num_ref_idx_l0_active_minus1, num_ref_idx_l1_active_minus1, more_modification_flag, and be_idx_in_ref_pic_list shown in FIG. 13 is the same as in FIG. 9.
When ref_pic_list_modification_flag_l1[i] is equal to 1, the number of times that more_modification_flag is equal to 1 following ref_pic_list_modification_flag_l1[i] shall not exceed (num_ref_idx_l1_active_minus1[i]+1). num_ref_idx_l0_active_minus1[i] indicates the maximum reference index for reference picture list RL0[i] corresponding to the buffer description BD[i].
The semantics of the syntax elements of the reference list updating information ref_pic_list_modification_flag_l0, ref_pic_list_modification_flag_l1, numb_ref_idx_l0_active_minus1, num_ref_idx_l1_active_minus1, more_modification_flag, and be_idx_in_ref_pic_list shown in FIG. 17 is the same as in FIG. 9.
The relationship between the reference list description updating information 324F included in the PPS 302F and the reference list description defining information 313 included in the SPS 301D is the same or alike as the relationship between the reference list description updating information 324 and the reference list description updating information 324F. Specifically, it is sufficient that “the reference list description updating information 324” in the above explanation is replaced by “the reference list description updating information 324F” and that “the reference list description updating information 324F” in the above explanation is replaced by “the reference list description defining information 313”.
The semantics of the syntax elements of the reference list description defining information ref_pic_list_modification_flag_l0[i], ref_pic_list_modification_flag_l0[i], num_ref_idx_l0_active_minus1[i], num_ref_idx_l1_active_minus1[i], more_modification_flag, and be_idx_in_ref_pic_list shown in FIG. 19 is the same as in FIG. 16.
The buffer description updating information 323G includes buffer description selecting information 351 (e.g. bd_select=2) to specify one selected buffer description and a buffer description modifying flag 352 (e.g. modify_flag=1) indicating whether or not the selected buffer description and the reference list description corresponding to the selected buffer description are to be modified. When the buffer description modifying flag 352 indicates that modification is performed, the buffer description updating information 323G further includes the buffer description modifying information 328 (BD modify). Furthermore, when the buffer description modifying flag 352 indicates that modification is performed, the PPS 302G includes the reference list description updating information 324G including the reference list defining information 329 (RLD define) which defines the modified reference list. On the other hand, when the buffer description modifying flag 352 indicates that modification is not performed, the PPS 302G does not include the buffer description modifying information 328 and the reference list defining information 329.
The semantics of the syntax elements of the reference list updating information ref_pic_list_modification_flag_l0, ref_pic_list_modification_flag_l1, num_ref_idx_l0_active_minus1, num_ref_idx_l1_active_minus1, more_modification_flag, and be_idx_in_ref_pic_list shown in FIG. 25 is the same as in FIG. 9.
When video data generated in the moving picture coding method or by the moving picture coding apparatus described in each of embodiments is decode d, compared to when video data that conforms to a conventional standard, such as MPEG-2, MPEG-4 AVC, and VC-1 is decoded, the processing amount probably increases. Thus, the LSI ex500 needs to be set to a driving frequency higher than that of the CPU ex502 to be used when video data in conformity with the conventional standard is decoded. However, when the driving frequency is set higher, there is a problem that the power consumption increases.
1. An image decoding method for decoding a coded bitstream, the image decoding method comprising:
constructing a first reference list including a plurality of pictures, each of the pictures having a Picture Order Count (POC) assigned thereto and being identified by one of a plurality of reference indexes, the reference indexes corresponding one to one with the pictures included in the first reference list, each of the reference indexes having a different index value, the first reference list being constructed based on the POC assigned to each of the plurality of pictures;
obtaining, from the coded bitstream, reference list reordering information for indicating details of reordering to be performed on the first reference list;
reordering the pictures included in the first reference list to generate a modified reference list by assigning new reference indexes using the reference indexes, the new reference indexes corresponding one to one with the pictures included in the modified reference list, each of the new reference indexes having a different index value; and
decoding a current picture or slice using the new reference indexes and the modified reference list resulting from the reordering,
wherein each of the reference indexes (i) identifies one of the pictures included in the first reference picture list such that the reference indexes correspond one to one with the pictures included in the first reference list and (ii) is used in assigning the new reference indexes in the reordering.
