output, so you can view it in the preview view of the multiview. Then, the
upstream key will be taken on air to the program output and off air to the
preview output in the next transition after executing a signal transition.
After that, press KEY button again to cancel the upstream key changing in
the next transition, the KEY button turns gray.
 There are multiple ways to transition a key to the program output. The key can be
cut on or off immediately or in the next transition. Use ON AIR button to
immediately cut the key on or off air to the current program output. Use KEY or
DSK button to cut the key on or off air to the program output in the next transition
controls.
Upstream Key Examples
For example, take upstream key for example, use KEY and CUT button to
observer the changes of upstream key in PGM and PVW views(BKGD is selected
in the examples).
Here's how to perform upstream key transition:
 Example 1
Push the upstream key on air to the program output, and cut it off air to the
program output in the next transition. The process is shown in Figure 4.1-52.
Step 1 Push upstream key on air to the program output
Press ON AIR button of the upstream key, you will see the upstream key is
on air both in program output and preview output;
ON AIR button is highlighted in red, and KEY button is gray.
Step 2 Change upstream key status in the next transition
Then, press KEY button of the upstream key, therefore the status of the
upstream key will be off air in the next transition, that is opposite to the
current status. And here you can see it off air in the current preview output,
but still on air in the current program output;
ON AIR button is highlighted in red, and KEY button is highlighted in white.
Step 3 Perform cut transition
Press CUT button in the transition area to perform cut transition. First, the
background signal on program bus and on preview bus are exchanged.
Second, the upstream key is off air in current program output and on air in
the preview output;
