Description

In,
8.5.3.1.6 Derivation process for motion vector predictor candidates

The equation 8-131 is not useful, since refIdxA is not going to be used for scaling.
mvLXA = MvLX[ xAk ][ yAk ] (8 130)
refIdxA = RefIdxLX[ xAk ][ yAk ] (8 131)

  • Milestone set to D9
  • Version changed from D8 (K0030) v4 to D9 (K1003) v10

According to whether a refIdx is used later in this process or not, the following derivations of refIdxA are useless:
refIdxA = RefIdxLX[ xAk ][ yAk ] (8 131)
refIdxA = RefIdxLY[ xAk ][ yAk ] (8 133)
refIdxA = refIdxLXB (8 150)

Furthermore there is a typo under the second 3.: "Tthe" -> "The"
