The Video Bridge tab is shown in Figure 4-2 .
The parameters on the Video Bridge tab are as follows:
Hysteresis Level : Allowable range: 0—1023. Defines the “cushion” level of the frame buffer,
that is, the number of locations that are considered the minimum fill level for FIFO
operation to start. Generally, this value should be between 12 and 20. It must be at least 16
less than the depth of the FIFO, and at least 16 less than the number of active video lines.
FIFO Depth : Specifies the number of locations in the input FIFO. The allowable values are
