46.9.19 Reference Picture Index 4 Base Address
Name: VDEC_PIDXBA4
Addresses: 0x00900048
Access: Read-write
ANC: Anchor Picture Type
Previous anchor picture type:
0: Intra
1: Inter
RCB: Rounding Control Bit
When low, 1/2 pixel motion compensation sum is rounded, otherwise clipped.
ACC_FW: Forward Motion Vector
Forward motion vector Y resolution:
0: 1/2 accuracy
1: 1/4 accuracy
OVERLAP_SM: Overlap Smoothing Method
Overlap smoothing method for macroblocks where PQUANT <= 8:
0: No overlap smoothing.
1: All macroblocks overlap smoothed.
2: Overlap smoothing depends on overflagmb syntax element per macroblock.
OVERLAP_EN: Overlap Smoothing Enable
Overlap smoothing enable. Defines if overlap smoothing is enabled for current picture (includes information about
PQUANT which must be >= 9).
MV_RANGE: Motion Vector Range
This control gives range to motion vectors:
0: Range is [-64,63.f],[-32,31.f].
1: Range is [-128,127.f],[-64,63.f].
2: Range is [-512,511.f],[-128,127.f].
3: Range is [-1024,1023.f],[-256,255.f].
