JCTVC-J0402 Crosscheck of Signalling of long-term reference pictures in the slice header in JCTVC-J0115 [Hendry, B. Jeon (LG)] [late] [miss]
JCTVC-J0530 AHG13: Crosscheck for Signalling of long-term reference pictures in the slice header (JCTVC-J0115) [??] [late]
JCTVC-J0116 AHG13: Signalling of long-term reference pictures in the SPS [A. K. Ramasubramonian, Y.-K. Wang, Y. Chen (Qualcomm), C. S. Lim (Panasonic), S. Deshpande (Sharp) , Hendry (LG)]

This document proposes to enable the inclusion of candidate long-term reference pictures, as part of the reference picture set signalling in the sequence parameter set. Two different options are provided. The document reports that, for test condition 2.6 in JCTVC-H0725, the proposed method uses 36% and 42% fewer bits, respectively for the two proposed options, to signal the syntax elements related to long-term reference pictures in the sequence parameter set and the slice header, when compared to the signalling in HEVC text specification draft 7.

The first presented option was a design considered at the preceding meeting in I0340, for which further study had been suggested. The second was a design that had also been in a version of I0340.

(A four-company proposal – also supported by additional non-proponents.)

Decision: Adopt "option 2" with u(v) coding of lt_idx_sps.
