VpsInterLayerMotionPredictionEnabled derivation

Reported by: Vadim Owned by: jlchen
Priority: minor Milestone: Draft 7
Component: SHVC text and test model Version: Draft 5 version 2
Keywords: Cc: jlchen, yanye, jillboyce, jct-vc@…

Description

VpsInterLayerMotionPredictionEnabled is derived with equation F-5 as follows:
VpsInterLayerMotionPredictionEnabled[ i ][ j ] = ( direct_dependency_type[ i ][ j ] + 1 ) & 0x2

So, the values are 0 and 2, however in the text VpsInterLayerMotionPredictionEnabled is checked whether it is equal to 1.

It is suggested to modify F-5 as follows:
VpsInterLayerMotionPredictionEnabled[ i ][ j ] = (( direct_dependency_type[ i ][ j ] + 1 ) & 0x2) >> 1
or
VpsInterLayerMotionPredictionEnabled[ i ][ j ] = (( direct_dependency_type[ i ][ j ] + 1 ) & 0x2) ? 1 : 0
