JCTVC-J0480 Crosscheck of long term reference pictures in SPS (JCTVC-J0116) [TK Tan (??)] [late]
JCTVC-J0118 AHG13: On signalling of MSB cycle for long-term reference pictures [A. K. Ramasubramonian, R. L. Joshi, Y.-K. Wang (Qualcomm)]

This document proposes changes to the semantics of the syntax elements poc_lsb_lt[ i ], delta_poc_msb_present_flag[ i ], and delta_poc_msb_cycle_lt[ i ] to improve the efficiency of signalling the MSB cycle for long-term reference pictures in the slice header. Changes to the RPS derivation process are also proposed, including swapping of the order of STRP and LTRP subset derivations, such that the STRP subset is derived first.

If the proposal in JCTVC-J0115 is adopted, then this proposal is claimed to become irrelevant and should be ignored.

No experiment results were provided.

To use the suggested scheme, the specification of the decoder process for building the reference picture set would need to be change. There were some problems in the text that was provided with the contribution for these changes. A revision of the contribution was provided to address that.

The proposed text may also include some editorial improvements of the expression of the existing scheme, and it was suggested for the editors to consider any such improvements. This was agreed. Decision (Ed.): Editor action item.

No action taken.
