// #define H_MV_HLS_7_POC_P0041_3            0 // (POC/P0041/POC reset) #3 It was remarked that we should require each non-IRAP picture that has discardable_flag equal to 1 to have NUT value indicating that it is a sub-layer non-reference picture.

// #define H_MV_HLS_7_POC_P0056_4            0 // (POC/P0056/layer tree poc) #4 Proposal 1: If the POC reset approach is adopted as the basis for multi-layer POC derivation, it is proposed to derive the POC anchor picture from the previous TID0 picture (that is not a RASL picture, a RADL picture or a sub-layer non-reference picture and not with discardable_flag equal to 1) of  the current layer or any of its reference layer. This is asserted to improve loss resilience and reduce bit rate overhead. Decision: Adopt Proposal 1 (with the suggested modifications Ewith text provided as P0297).
