Incorrect DeltaPocMsbCycleLt Calculation in HM-11.0

Reported by: bheng Owned by:
Priority: minor Milestone: HM-11.1
Component: HM Version: HM-11.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

When delta_poc_msb_cycle_lt[i] is not present, it is inferred to be equal to 0.

Therefore, based on the following formula, for the first LTRP specified in the slice header (i = num_long_term_sps), the variable DeltaPocMsbCycleLt[i] should be reset to 0 if delta_poc_msb_present_flag[i] = 0.

if( i == 0 | | i == num_long_term_sps )

DeltaPocMsbCycleLt[i] = delta_poc_msb_cycle_lt[i]

else

DeltaPocMsbCycleLt[i] = delta_poc_msb_cycle_lt[i] + DeltaPocMsbCycleLt[i − 1]

The attached patch can be used to fix this issue in HM-11.0.
