appear off-center. The X Position refers to the horizontal placement and the
Y Position refers to the vertical placement. 0, 0 is the upper left hand corner,
and that is the setting for most TVs. (All numbers are positive numbers, so
the Y values represent the distance from Y=0 or the top of the screen).

Scaling Parameters: The X Scaling and Y Scaling parameters set a scaling
factor that can be used to shrink or stretch the Flash template application on
the TV screen. A scaling factor of 1.0 (and zero) is equivalent to 100% of the
original size, where X Scaling represents the width and Y Scaling represents
the height. A scaling factor of 0.5 will shrink the Flash template application
down to 50% (or half) of its original size. For most TVs, both scaling factors
will be 1. The scaling factors are required for older TVs that do not have
settings to control over scan on the TV. By default, some of these TVs suffer
from over scan, which causes some of the content to be clipped. This may
not be noticeable when displaying a full-screen video channel, but it is very
noticeable when displaying graphics (for example, a 3-Region template).

If you are uncertain of the correct values for your TV type, check the TV
manufacturer’s documentation for the correct values. If the information is not
available, start with the defaults and adjust the parameters as required until the
image fits the screen properly. This will need to be done only once per TV
model.

• Volume Strategy:
o
External: The volume on the TV is controlled by sending serial commands
from the DMP to the TV (via RS-232). Note: The configuration of the External
Volume strategy is recommended because TVs typically have better audio
range than the DMP and many TVs provide a visual indicator of the volume
level as the volume is being changed. This strategy also avoids problems if
someone changes the volume via the TV front panel buttons or IR remote.

o
Internal: The volume on the TV is controlled by changing the volume of the
audio feed as it is transmitted from the DMP. This volume strategy would
typically be used if the TV does not have RS-232 control and volume is to be
controlled by Cisco StadiumVision Director remotely, the DMP IR remote, IP
Phone or Crestron/AMX controller.

o
None: The volume cannot be adjusted. This is useful for TVs that are used
for video only where audio (if any) is provided separately (such as in a bar
where an overhead system provides the audio).

Configuring Display Specifications and RS-232 Commands
A Cisco StadiumVision Director Display Specification is a container that holds
attributes that are unique to a specific TV make and model. Attributes include things
like RS-232 commands, RS-232 responses, timing values, input labels, etc.

like RS-232 commands, RS-232 responses, timing values, input labels, etc.
RS-232 commands are used to control TV functions like on, off, mute, volume and
external input. In more specialized scenarios they may also be used to configure TV
external input. In more specialized scenarios they may also be used to configure TV
