JVET-AM0285 AHG12: Reuse of TALF control information [Y. Bai, M. Jia, W. Niu, S. Xie, C. Huang (ZTE)] [late]

In this contribution, it is proposed to store the Slice-level and CTB-level TALF control information for use in future frames. Compared to ECM-17.0 anchors, partial simulation results are:

• RA:
  • Class B, {0.00%, -0.03%, 0.00%};
  • Class C {-0.02%, -0.02%, -0.01%}
• LDB:
  • Class B*{ 0.00%, -0.04%, 0.05%}
  • Class C {-0.02%, 0.04%, 0.20%}
  • Class E {-0.05%, 0.44%, 0.30%}

Restriction based on temporal layers is applied in this proposal.

Both cross checker confirmed that the partial results are matching, and commented that the concept is straightforward and has no impact on runtime.

It was commented that the gains are very small, but several experts expressed interest given the proposal likely doesn’t introduce additional complexity.

It was agreed to investigate this in an EE
