filtering. For vertical scaling, there are 2 separate coefficient tables: one for luma and
the other for chroma, thereby allowing the use of different filter coefficients for chroma
and luma.
2.3 Data Processing in MBS
Table 1, Table 2, and Table 3 tabulate the various processing modes and orders in the
MBS.
