Video Flow through the Switcher
The following three diagrams illustrate how video flows through each Synergy Switcher. These
drawings illustrate each switcher’s visual and electronic concepts of upstream and downstream, and
are designed to help you visualize and understand each switcher’s architecture
from a production
standpoint .
Synergy 2 Video Flow
The following block diagram illustrates the flow of video through the Synergy 2 Switcher.
Synergy 2 Video Flow
Please note the following important points:
• The Synergy 2 is a two MLE switcher with 16 inputs standard. Video flows into each
MLE as indicated above, where crosspoints can be selected for effects creation.
• MLE 1 or 2 can be selected independently as the switcher output. In this condition, with
no re-entry crosspoints selected, each MLE obeys the standard rules for upstream and
downstream placement of images.
• Within MLE 1, by itself, the Background and Preset buses are electronically the farthest
upstream, Key 1 is displayed mid stream and Key 2 is displayed downstream.
~ Visually, all images on the background buses appear behind both keyers.
~ In the default state, a key enabled on Key 1 is displayed visually over the two
background buses (and all transitions), but visually under Key 2.
~ In the default state, a key enabled on Key 2 is displayed visually over the
background buses and Key 1.
~ If the KEY OVER button is pressed in Key 1, the priority is changed and Key 1 is
displayed visually over Key 2.
Operating
Tip
You can also change the priority of the two keyers in the Key Setup
Menus by toggling the Key Over softkey between On and Off . Refer
to the section “ Using Keys ” on page 7-20 for more information.
