Description

4:2:2 support for motion

adaptive algorithm

On or Off

Turn on to avoid color artefacts when

processing 4:2:2 Y'CbCr data when you select

Motion Adaptive deinterlacing method.
You cannot turn on this parameter if you are

not using either two channels in sequence or

two channels in parallel.
Note: Available only when you select

Motion Adaptive as the deinter‐

lacing method.

Motion bleed

On or Off

Turn on to compare the motion value with

the corresponding motion value for the same

location in the previous frame. If it is greater,

the new value is kept, but if the new value is

less than the stored value, the motion value

used is the mean of the two values. This

reduces unpleasant flickering artefacts but

increases the memory usage and memory

bandwidth requirements.
Note: Available only when you select

Motion Adaptive as the deinter‐

lacing method.

Run-time control of the motion-

adaptive blending

On or Off

Turn on to add an Avalon-MM slave

interface that controls the behavior of the

motion adaptive algorithm at run time. The

pixel-based motion value computed by the

algorithm can be replaced by a user selected

frame-based motion value that varies between

the two extremes of being entirely bob or

entirely weave.
You cannot enable both run-time control

interfaces at the same time.
Note: Available only when you select

Double buffering.

Number of packets buffered per

field

1–32, Default = 1

Specify the number of packets that can be

buffered with each field. Older packets are

discarded first in case of an overflow.
Note: You must select double or triple-

buffering mode if you want to

control the buffering of non-image

data packets.
