GRAPHICS CODEC
Note
These functions can only be activated if a graphics codec is
part of the system.
3.3.6.2.1
GRAPHIC SOURCE
The GRAPHIC SOURCE field is a list of all connected graphics sources.
Sources can be selected by clicking.
3.3.6.2.2
SINGLE SHOT
Clicking the SINGLE SHOT key generates and transmits a single graphics
picture. The display of the transmitting terminal also displays the (frozen)
transmit picture.
Note
The SINGLE SHOT key should not be clicked repeatedly as
this can lead to decoder errors in the receiver.
SINGLE SHOT should therefore be clicked again only after the
last transmitted graphics picture has been decoded at the re-
ceiver.
3.3.6.2.3
Drawing an overlay picture
The drawing is done with a mouse. All that is required is a PC mouse connec-
ted to the RS232C/MOUSE socket. It should then be possible to move the cur-
sor in the picture output by the graphics codec. To draw a line, press the left
mouse key and move the cursor. The other cursor is controlled from the far
end. The two overlay pictures are displayed in black and white.
Note
If the overlay picture is to be transmitted, then the LSD mode
has to be set to cursor in the data panel (SECTION 3.3.7.1).
3.3.6.2.4
PREVIEW
The PREVIEW function switches the JPEG graphics codec input through to
the output. The graphics camera picture is then displayed and can be adjusted
or focused, for example. The preview picture is not transmitted.
The preview mode stays activated until a graphics picture is either transmitted
to or received from the remote end.
3.3.6.2.5
CLEAR OVERLAY
Clicking the CLEAR OVERLAY key deletes the graphic overlay memory. Both
overlay pictures are deleted locally.
3.3.6.2.6
SHOW GRAPHIC
The SHOW GRAPHIC key is for the quick switchover in the PICTURE IN PIC-
TURE function (see SHOW VIDEO). Clicking this key corresponds to the set-
tings “BACKGROUND
→
GRAPHIC” and “PIP
→
INCOMING MOTION VI-
DEO” in the PIP window.
