Application 2: Connecting Multiple MGP Pros in Succession
(Daisy-chaining)
By connecting multiple MGP Pros together in succession (“daisy-chaining”) via the HDMI
Output and HDMI Background connectors, you can display up to 12 windows on the output
screen. You can connect up to three MGPs in this way (see the examples in
figure 45
on
the next page).
NOTE:
This application can also be used with an MGP 462 Pro. However, because
the MGP 462 Pro has only two windows, you are able to display half the number of
windows that the MGP 464 Pro can support. For example, when you daisy-chain three
MGP 462 Pro processors together, 6 windows are provided instead of 12.
Connecting via the HDMI Background connector has the advantage of the input not being
scaled. Therefore, no analog or digital sampling is required and there is no signal loss.
NOTE:
In
figure 45
, the MGPs are given letters in the order of their priority, starting with
the unit closest to the output display. Therefore, the first MGP Pro in the chain is shown
as unit C (or B, if there are only two MGPs). The second MGP Pro is designated as unit
B, and the third is unit A.
Figure 45
shows diagrams of three possible configurations for an MGP Pro.
1.
8-window configuration:
Two MGP Pros are daisy-chained together, so that eight
windows (four from each MGP Pro) are displayed on the output screen. (On the MGP
Pro, this is a 4-window configuration.)
•
The HDMI Output of the first MGP Pro (unit B) is connected to the HDMI
Background input of the second MGP Pro (unit A).
•
The first diagram in the row shows the output display with one MGP Pro attached.
The second diagram shows the display with two MGPs attached.
2.
12-window configuration:
Three MGPs are daisy-chained so that 12 windows
are displayed on the output screen. (On the MGP 462 Pro, this is a 6-window
configuration.)
•
The HDMI Output of the first MGP Pro (unit C) is connected to the HDMI
Background input of the second MGP Pro (unit B).
•
The HDMI Output of the second MGP Pro (unit B) is connected to the HDMI
Background input of the third MGP Pro (unit A).
•
The first diagram in the row shows the output display with one MGP Pro attached.
The second diagram shows the display with two MGPs attached. The third diagram
shows the display with all three units connected.
3.
8-window with live background configuration:
An HDMI computer (or another
HDMI source) is daisy-chained to two MGPs, so that eight windows are displayed in
front of a live video background from the HDMI source.
•
The HDMI source is connected to the HDMI Background input of the first MGP Pro
(unit B).
•
The HDMI output of the first MGP Pro (unit B) is connected to the HDMI
Background input of the second MGP Pro (unit A).
•
The first diagram in the row shows the HDMI computer, which is the input source.
The second diagram shows the display with one MGP Pro attached. The third
diagram shows the display connected to two MGPs. (On the MGP 462 Pro, this is a
4-window configuration.)
