Description

At the strasburg meeting, ARP mismatch between text and software was reported. The issues are mainly related to F0105, F0123 and I0051. This ticket reports the details and a suggested fix (relative to HTM-12.2 and J1001_v3). The suggested fix doesn't affect coding results in CTC. The suggested patch includes the four macros (FIX_TICKET_89_REFIDX, FIX_TICKET_89_REFCHECK, FIX_TICKET_89_REFCLEAN, and FIX_TICKET_89_REFCLEAN2).

Issues:
(1)Software issue(FIX_TICKET_89_REFIDX):

  • typos in arpIdx selection

(2)Software and text issue(FIX_TICKET_89_REFCHECK):

  • wrong or missing availablity checks in inter-view ARP

Specifically, in inter-view ARP, the ARP reference list X is replaced to Z as proposed in F0123 and I0051, so the software and text should be modified to check the Z rather than X. That's the reasonable harmonization with F0105.

Additionally, a software clean up is provided (FIX_TICKET_89_CLEAN and FIX_TICKET_89_CLEAN2).

Note: FIX_TICKET_89_CLEAN removes unnecessary conditions (2Nx2N check and depth chech are processed before ARP function in text and software, so we can remove them) and removes non-used variable (pNewMvFiled). FIX_TICKET_89_CLEAN2 merges uni-prediction part and bi-prediction part into one part as text specifies. The CLEAN2 changes can be large but it really helps cleanup.
