in the spec(04/2013) for page 119, as for the spatial merging candidates define,there are two follow condition:

When one or more of the following conditions are true, availableA1 is set equal to FALSE

  1. xPb >> Log2ParMrgLevel is equal to xNbA1 >> Log2ParMrgLevel and yPb >> Log2ParMrgLevel is equal to yNbA1 >> Log2ParMrgLevel.
  1. PartMode of the current prediction unit is equal to PART_Nx2N, PART_nLx2N, or PART_nRx2N, and partIdx is equal to 1

for the condition 1,i am confuse about it ? Why do it need such a restriction that it is related to Log2ParMrgLevel ?

for the condition 2,According to the spec 6.4.2, when the current prediction unit is equal to PART_Nx2N and partIdx is equal to 1, i find the sameCb is true ,
and consequently the availableA1 is set equal to TRUE.

so i have a doubt about the condition 2 ? Why do it also need such a restriction?
