Configuration
Multi-Format STB Quick Start
15
To fine tune the display area for connected devices:
1. Open
adjust.xml
in a text editor such as Notepad.
2. Add one line for each Multi-Format Set Top Box you wish to fine tune. This line must
contain an XML tag containing the MAC address of the box and an adjustment value in
the range of 1–20 per cent. For example if the set top box has an MAC address of
00-01-
38-EC-D9-D1
and requires a screen adjustment (shrinkage) of 5 per cent, the tag entry for
that device would be:
<MAC00-01-38-EC-D9-D1>
5
</MAC00-01-38-EC-D9-D1>
The MAC address format is six groups of two digit hexadecimal numbers separated by
either hyphens ("-") as above or by colons (":"). If colons were used as a separator in the
above address it would be written
00:01:38:EC:D9:D1
The XML document specification does not allow multiple sequential colons to be used in
an XML tag. To use a colon-separated MAC address as an adjustment tag simply replace
the colons with hyphens when forming the tag so that it looks like the example above.
3. Add one tag for each additional set top box that needs adjustment.
4. Reboot the server when done.
Local Mode
You can adjust the channel guide graphics display area of an output device so that the entire
output is shown on the monitor by modifying the
adjust.xml
file. This file, found in the
data
folder, lets you scale the channel listing graphic to match the size of your TV. On certain TV
sets, the image can be chopped of by the bezel, causing a loss of graphic imagery. You can
adjust the value in terms of screen percentage. The default is 10, meaning that the graphic
image will be reduced by 10%. Be aware that all TV’s are not alike. Values that work on some
TV's may not work well on others, even the same brand. A setting of 0 is maximum size.
Valid ranges are from 0 to 20. Please note that this setting does not affect the size of full
screen video. Depending on how your system is configured, this file is located on the set top
box or on a VEMS server.
To modify the display area of an output device:
1. Navigate to
root\data\adjust.xml
using Telnet or FTP. (See Updating channels.xml on
page 22 for instructions that explain how to access this file.)
2. Open the file in Notepad or a similar editor.
3. Enter a percentage value for the amount of shrinkage (range = 0–20). For example, set to
5 to shrink the display area by 5 percent.
<STBLocalParms>
<Adjust>
5
</Adjust>
</STBLocalParms>
4. Save the file and exit when done.
Adjusting the Display Area of Output Devices (VEMS 6.x)
If necessary, you can fine tune the channel guide graphics display area for output devices (i.e.
monitors) connected to each set top box in your network. You can shrink the display area of
the output by up to 20 per cent to match the unique specifications of each monitor.
Note that
to use this procedure, the STB must be configured in VEMS as explained in the Portal Server Admin
Guide
.
