Basic Video Processing 
 
 
    This section introduces basic functions used for video
 
processing on the switcher.

In the M/E banks and PGM/PST bank, the switch from the

current video stream (appearing on the corresponding
 
program monitor) to a new video stream is referred to as a
 
transition. 
In the M/E banks and PGM/PST bank, you can change one
 
of the images, the background, and keys 1 to 4
 
(downstream keys 1 to 4 in the PGM/PST bank), and also
 
vary combinations of these simultaneously. 
Inserting or deleting key 1 and key 2 
 
 
 
Key 1 
 
The following are examples of transition. 
 
 
Changing the background 
A background transition switches from the video currently
 
selected on the background A bus (the current video) to the 
 
Transition
 
 
 
 
 
 
Key 2 
video selected on the background B bus (the new video).

Deleting key 1 and inserting key 2 
 
 
Simultaneously changing the background 
and keys 
You can change one or more of the four keys (downstream
 
keys on the PGM/PST bank) and the background at the
 
same time. 
 
Background A  Background B 
Key 1 
 
 
In the default selection of flip-flop mode 
(
1 
p. 73), the
 
background always switches in the direction from the A
 
bus to the B bus. When the transition completes, the cross-
 
point selections on the A and B buses are interchanged. 
 
 
Inserting and deleting a key 
You can insert one or more of the four keys (downstream
 
keys on the PGM/PST bank). 
If you select a key which is already inserted, the transition
 
will delete the key. 
A simultaneous combination of deleting and inserting keys
 
is also possible.
