Controlling External Devices

You can operate the system while controlling the
following types of external device:
• Devices supporting P-Bus (Peripheral II protocol)
• Devices supporting GPI
• VTRs
• Disk recorders (Sony disk 9-pin protocol and video disk
communications protocol)
• Extended VTRs (Abekas A53 protocol)
For details about the devices that can be connected,

Keyframes
A keyframe represents an instantaneous state of an image;
it can be saved in a register and recalled for reuse. By
arranging a number of keyframes on the time axis, and
interpolating between successive keyframes, you can
create a "keyframe effect" in which there is a continuous
change from each keyframe to the next.
The following figure shows three keyframes created with
a wipe pattern (the circle) in different positions. This is
interpolated to create the effect shown.

Example of keyframes and effect execution
You can save the sequence of keyframes representing a
single effect in a register. Then by recalling this register,
you can replay the same effect.

Snapshots
The term "snapshot" refers to a function whereby the
various settings required to apply a particular effect to an
image are saved in a register as a set of data, for recall as
required, to recover the original state.
Snapshots are divided as follows.
• Snapshots applying to a particular region (functional
block of the switcher or DME)
• Master snapshot
• Key snapshot
• Wipe snapshot
• DME wipe snapshot

Macros
The term "macro" refers to the function whereby a
sequence of signal selections and other operations on the
control panel is saved as data in memory (macro register),
so that it can be recalled as required to automatically
execute the same sequence of operations.
The individual control panel operations constituting a
macro are termed "events."
Macros also provide the following functions.
Menu macros
The term "menu macro" refers to the function whereby a
sequence of menu operations is saved as an event, so that
it can be recalled as required to automatically execute the
same sequence of operations.
