AP M -1. If the number of pictures maximally accommodated by the multiple reference picture buffer corresponds to M , the motion estimation when coding picture m , if 0 M , the maximum number of pictures M can be used. (...) If a custom picture clock frequency was not in use for the reference picture, the two MSBs of TRP are zero and the LSBs contain the eight bit TR found in the picture header of the reference picture. (...) If RPI is set to ‘0’, no picture is removed from the memory unless a picture is added and the multiple reference picture memory is full.

(...) If a custom picture clock frequency was not in use for the reference picture, the two MSBs of TRP are zero and the LSBs contain the eight bit TR found in the picture header of the reference picture. (...) For B pictures or the B-picture part of an Improved PB frame, the picture having the temporal reference TRP is used for the prediction in the forward direction.

For the reference, since the conventional B picture always has a P picture as a subsequent picture, this guarantees that a motion always exists between two pictures except that MB mode of collocated macroblock of the subsequent P picture is intra. (...) That means the temporal correlation between the temporally-preceding pictures and B picture is so high, while temporal correlation between B picture and the temporally-following pictures is very low. (...) This fact indicates that there is a motion between B picture and the immediately temporally-following picture and also there may be a scene change between B picture and the immediately temporally-preceding picture.

The other is QP used in B pictures. For the reference, the number of multiple reference frames used in B pictures is identical to that in P pictures. 2. (...) In image(), if the number of B pictures inserted is equal to or more than 1, then image() does B picture coding after P picture coding is done. 6. (...) B picture is decoded from previous decoded P pictures.

In the proposed method, the blocks in B-pictures can be encoded by referring to previous B-pictures in addition to I- or P-pictures as forward reference pictures. (...) And we assume that 4 P-pictures are used as the forward reference pictures for the P-picture coding, and 4 P-pictures and 1 B-picture are used as the forward reference pictures for the B-picture coding. (...) The index of the picture B11 is smaller than that of the picture P12 while the picture P12 is nearer to the picture B13 than the picture B11 in the display order.

A reconstructed picture corresponding to a missing picture number is called an “invalid” picture. (...) Picture number 7 is assigned to both picture B EL1.1.7 and picture P BL.0.7, as the B picture is not stored in the multi-picture buffer. However, as picture B EL1.1.6 is stored in the multi-picture buffer, the picture number is incremented normally in the picture following it.

This should be the case regardless of what picture type those pictures have. If the forward reference pictures is not the same as the forward reference picture of the corresponding backward reference picture, motion vector scaling should be changed as appropriately. (...) However, in JM1 and JM2, the code is assigned to B-picture in the memory to signaling reference number even if B-pictures cannot be reference for P-picture coding. (...) This should be the case regardless of what picture type those pictures have. 3.2 Change of default relative index assignment for storing into memory The default index order for B pictures is defined such that short-term pictures that temporally precede the B picture are distinguished from short-term pictures that temporally follow the B picture, based on the temporal reference for each reference picture.

In coded video sequences that include alpha, there would be one alpha picture for every primary coded (luma-chroma) picture, and the coded alpha picture would be contained in the same access unit as its corresponding primary coded picture. (...) If the primary coded picture is an IDR picture then the alpha picture shall be inferred to be an alpha IDR picture with the same idr_pic_id. 2. (...) A coded slice of any alpha coded picture shall obey the same constraints as a coded slice of a redundant picture, with the following exceptions. · If the associated primary coded picture is an IDR picture, then the alpha coded picture is inferred to also be an IDR picture to be decoded as if it had nal_unit_type = 5.
