The enhanced reference picture selection mode contains a feature called Reference Picture Pruning. (...) PM 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.

Handling of reference pictures In the direct mode of JCD, a forward reference picture that is selected out of forward reference picture set, and a backward reference picture assigned to index 0 are used for the bi-directional prediction. (...) The picture with index 0 of forward reference picture set is only used as the forward reference picture for direct mode b. (...) If the direction information for backward reference picture with index 0 and forward reference picture that is selected out of forward reference picture set show that both two reference pictures are located in the normal direction of current picture, the direct prediction is used.

Encoders may wish to realize low buffering delay by allowing pictures to be dropped occasionally. As a result of this it may happen that at some time when a picture is expected to be removed from the VBV buffer there will not be sufficient data in the buffer to remove a complete picture. (...) If both the picture about to be coded and the previously decoded picture are I or P and there is not sufficient data in the buffer, no data is read out of the buffer and the previous decoded pictures are displayed again. (...) The VBV is examined immediately before removing any data (sequence header data, group of picture layer or picture) and immediately after each picture is removed.

A H.26L P-picture can have more than one reference picture. (...) An alternative is to apply QB pictures to the H.26L baseline. As shown Figure 1 (b), all the P-pictures from the 3rd picture on are replaced by the QB pictures, each QB picture is predicated from the two most recently encoded reference pictures. (...) Therefore, in the cases of less than three reference pictures used (1 or 2 reference pictures), the QB-picture is a superset of the current H.26L P-picture. 3.

Proposed text: · If sequence parameter set NAL unit or picture parameter set NAL unit are present in the access unit, they shall precede the primary coded picture. · If sequence parameter set NAL unit is present in the access unit, seq_parameter_set_ID of the sequence parameter set shall be the same as that of the primary coded picture. · If picture parameter set NAL unit is present in the access unit, pic_parameter_set_ID of the picture parameter set shall be the same as that of the primary coded picture.

Item 3 Subclause : D.2.8 Decoded reference picture marking repetition SEI message semantics Problem: original_frame_num indicate the frame_num of the picture where the repeated decoded reference picture marking syntax structure originally occurred. (...) The picture indicated by original_frame_num is the last coded picture from IDR access unit if there are more than one coded pictures in the sequence.

That means is , the memory has only the picture with the same time stamp before SP-picture. (...) If the current picture is stored picture, PN of the following picture should be PNnew +1. And if the current picture is non-stored picture, PN of the following next stored picture should be PNnew 5.

However, it indicates that the current picture was not actually scanned as a progressive-scan picture. In other words, it indicates that the current coded picture contains only half of the lines of the full resolution source picture. (...) The encoder shall use a picture size (custom picture size, if necessary) such that the picture dimensions correspond to those of a single field. 3.

The encoder (Video and Systems) must ensure that the coded data of the base layer picture, which is necessary for decoding the upper layer pictures, be made available prior to the time the upper layer pictures are decoded. It is noted that if picture skipping is necessary in the base layer the most recently locally decoded base layer picture is used for prediction also for the subsequent upper layer pictures (e.g. Pictures 2 and 3 in the above illustration) END

At the decoder, if GFID changes and the picture type does not change, we know that the picture header was lost and that the picture type has changed. (...) It is assumed that B-picture information is less important than EI- or EP-picture information, thus a picture type change from EI or EP to B is not used. (...)
