Proposal: Move the paragraghs to an appropriate location (primary picture == IDR picture, redundant picture != IDR picture) in the if-otherwise structure. (...) These pictures are herein referred to as the target pictures. (...) Proposal: Replace with singular IDR picture: "If a redundant picture corresponding to the primary coded picture is not an IDR picture," ...

Picture Numbers enable decoders to detect which reference pictures were lost and to carry on decoding in case of a loss of B pictures or a picture loss in higher scalability enhancement layer. (...) For B pictures, Picture Number shall be incremented relative to the value in the most recent stored non-B picture in the reference layer of the B picture which precedes the B picture in bitstream order (a picture which is temporally subsequent to the B picture). (...) If the difference of the Picture Numbers of two consecutively received and stored pictures in the same enhancement layer is not one, and if the pictures do not represent approximately the same pictured scene content as described above, the decoder should infer a loss of pictures or corruption of data.

For example, a section of video bit-stream may contain P-picture P1, B-picture B2, P-picture P3, and P-picture P4 captured and displayed in this order. (...) The GFID of the corrupted picture is the same as the one in the previous picture, and therefore the picture header is essentially the same as in the previous picture, and the decoder can reconstruct the corrupted frame using the picture header of the previous picture. (...) Encoders should not insert reference picture numbers in B-pictures, and decoders shall ignore any reference picture numbers appearing within B-pictures.

If the number of pictures maximally accommodated by the multiple reference picture buffer corresponds to M, the motion estimation when coding picture m: 0(m(M-1can utilize m pictures. (...) If RPI is set to ”1”, a picture is removed from the multiple picture memory. (...) If API is set to ”1”, the currently decoded picture is added to the multiple picture memory. N.4.1.17 Macroblock Layer The macroblock layer syntax is modified if Enhanced Reference Picturee Selection is indicated and if the number of selected reference pictures (NRA value) is greater than one.

If a missing picture is detected when decoding a GOB or Slice layer, the concealment is applied to the picture as if the missing picture would be detected on the picture layer. (...) The memory reduction is accomplished by partitioning each reference picture into sub-pictures. While encoding, the encoder may remove sub-pictures from reference pictures in the multi-frame buffer. (...) If a missing picture is detected when decoding a GOB or Slice layer, the concealment is applied to the picture as if the missing picture would be detected on the picture layer.

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. In that case, the picture with index M-1 is removed from the multiple picture memory. (...) If a custom picture clock frequency was not in use for the reference picture, the two MSBs of TR are zero and the LSBs contain the eight bit TR found in the picture header of the reference picture.

GFID shall have the same value within one picture. Moreover, GFID shall have the same value as in the previous picture if certain fields in picture layer data remain in effect as for the previous picture. (...) If the GFID of the segment header is the same as in the previous picture, the picture data can be decoded using the picture header from the previous picture. (...) If the picture header of that picture contains SEI picture layer data repetition, the decoder can recover the picture header of the current picture.

For the second field picture of the same frame we increment PN by 0. At the end of decoding each picture, the decoder must decide whether the current picture is a stored or non-stored picture in the Multi-Picture Buffer. (...) It is not present if the picture is an I picture. It is present at least once in P pictures and at least twice in B pictures. (...) It follows an RMPNI “end loop” indication when the picture is not an I picture. It is the first element of the RPS layer if the picture is an I picture.
