Defining Partial Images
When using three buffers, one buffer (the Receiving Buffer) is used to re-assemble an image before it is
displayed on screen. When a new packet arrives, if it belongs to an image other than the one currently
being re-assembled, it is discarded. You can use the
NewImagePacketThreshold
control to determine
when the image in the Receiving Buffer is defined as a partial image. When the number of packets
received from images (other than the one in the Receiving Buffer) exceeds the value entered, the image in
the Receiving Buffer is either discarded or displayed as-is.
If you enter a value of
0
, the vDisplay IP engine immediately discards or displays the image in the
Receiving Buffer when a packet from a different image is received.
The
NewImagePacketThreshold
setting is closely linked to the
DisplayPartialImages
setting. Once you
have defined the number of packets that define a partial image, you can choose whether to display or
discard the partial image using the
DisplayPartialImages
setting, described in the next section.
