5.4.1.1.1JVT-AB030 (Prop 2.2/3.1) [Y.-J. Jeon, B.-M. Jeon (LG), S. Gao, L. Xiong (Huawei)] Comments on JMVM 8.0
At the last meeting, a one bit flag, non_anchor_ref_lX_sample_pred_flag, was adopted to allow different view dependencies for inter-view sample prediction (ISP) and motion skip (MS). From this, the view dependencies for interview sample prediction and motion skip can be set differently.
In some old JMVM, the dependencies for ISP and MS were the same. At the last meeting, there were proposals to change that, and a flag was created for the SPS. Flag = 0 indicates not used for ISP but used for MS; Flag = 1 indicates used for ISP and may or may not used for MS.
Flag is called non_anchor_ref_lX_sample_pred_flag.
Remark: There may be an issue with common conditions or software, but not with the draft spec. ISP is allowed for P views for non-anchor pictures, although that capability is not used in the common conditions.
Proponent wants to be able to determine if a particular view is used for MS. Remark: Why? What is important to know, for single-loop decoding purposes, is only whether a view is used for ISP, not whether it is used for MS.
Off-line study was conducted to determine if there is a spec problem or a common conditions problem or a software problem or no problem and the topic was discussed further. It was concluded that no action is needed to address this issue.
