Frame Memory
Overview
A frame memory is a function that freezes and captures a
single frame of the input video for use as content. You can
also specify a range in the input video to create a clip
(frame memory series of still images).
You can also import a still image or video file created
externall
y for use as frame memory content.
Areas Used for Frame Memory
Two areas are used for frame memory.
Frame memory work area: An a
rea for creating and
working with content.
This area is volatile memory, so when the system is
powered of
f the content in frame memory will be lost.
Content storage: Area for saving created content and
i
mported content.
When used for frame memory operat
ions, the target
content is loaded into the frame memory work area.
Number of content resources that can be stored
The number of content resources (number
of frames) that
can be stored in frame memory is given below.
For combined content, the number of content resources
(n
umber of frames) that can be stored is halved.
Frame Memory Input and Output
There are two systems for frame memory input: frame
memory source 1 bus and frame memory source 2 bus.
There are 16 channels for frame memory output: FM1 to
FM16.
You can store and recall an image on each frame
memory output channel. By assigning FM1 to FM16 to
cross-point buttons, you can use frame memory output as
input content.
The two frame memory input systems are assigned to two
co
nsecutive frame memory outputs (odd-numbered and
even-numbered frame memory output combinations,
such as FM1 & FM2 or FM3 & FM4).
Frame memory source 1 bus is used on the odd-numbered
frame memory output channel, and frame memory source
2 b
us is used on the even-numbered frame memory output
channel.
When the system signal format is 2160P, only six
channe
ls comprising FM1 to FM6 can be used.
Group mode (combine channels)
When group mode is enabled on consecutive odd-
numbered and even-numbered frame memory output
channels, the two channels are combined.
Frame memory operations control t
he combined frame
memory output channels.
When combined content is sel
ected, content 1 and content
2 of the combined content are recalled on the two
combined frame memory output channels, respectively.
V/K mode
When V/K mode is enabled, selecting a signal on the
frame memory source 1 bus will automatically select the
paired key signal on the frame memory source 2 bus.
