External Device Control

You can operate this system while controlling the
following types of external device.
• P-Bus (Peripheral II protocol) devices
• GPI devices
• VTRs
• Disk recorders (video disk communications protocol,
Odetics protocol)
• Extended VTRs (Abekas A53 protocol)
For details about the devices that can be connected,
consult your Sony representative.
You can also control an external device by registering
timeline keyframes beforehand.
For details, see "External Devices" (page 283).

Keyframes

A keyframe represents an instantaneous state of an image,
which 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,
interpolated to create the effect shown.

Effect execution
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.
For details, see "Keyframes" (page 297).

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 classified as follows.
• Snapshots applying to a particular region (functional
block of the switcher or DME)
• Master snapshots
• Key snapshots
• Wipe snapshots
• DME wipe snapshots
For details, see "Snapshots" (page 330).

Utility

The utility function allows you to assign an arbitrary action
or a shortcut for frequently used menu to a particular
button, to instantly recall the action or menu by pressing
the button.
For details, see "Utility Overview" (page 340).

Shotbox

The shotbox function allows you to recall any snapshot or
keyframe effect for specified regions (see page 297)
simultaneously.
For details, see "Shotbox Overview" (page 342).

Macros

The macro function allows you to store a sequence of
signal selections and other operations on the control panel
as data in memory (macro register), and then recall the
data, when 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 menu macro function allows you to register menu
operations as events, which can be recalled, when
required, to automatically execute the same menu
operations.
Macro timeline
You can automatically execute a sequence of macro recall/
execute actions by registering them on a timeline, in the
same way as for keyframes in an effect.
