Prima IP User Guide Rev. 1.6
allows or you need higher video quality instead of higher speed, just change the video filter
from Low to Medium or even to High to increase the video display quality on viewer screen
on the remote login client. To raise the Video Filter Level, please go to the Video Server
Page in Prima IP Web Management Interface, and select the filter as either Medium or High
Quality according to your requirements. Note that, High Quality video filter gives high
quality always on the expense of video
response speed on the viewer screen.
(2) The transitional effect of Windows XP is enabled. The transition effects of menu will
cause refreshing problems in Low/Medium Video Filter settings. Thus, if you are using a
Low/Medium Quality Level of video filter, either try to raise the video filter level to High
Quality (at the expense of response speed) or just turn off the transitional effects of
Windows XP. To turn off the transitional effects of menu on Windows XP, please refer to
Section 2.3, Prepare your Computers for Connections to Prima IP. Also note that Prima IP
local console is not affected at all by the Video Filter settings or by the transitional effects on
Windows XP.
Q. The Prima IP booting time has become unduly longer over several minutes.
What’s wrong?
A: Please make sure that the external authentication, PPP server/client, time server as well as
power control settings are correct. If you don’t use all these features or the
authentication/time servers are not available, just try to disable them to save booting time
since if you don’t have all these servers present, the Prima IP will try to look for them till
timeout. That will waste Prima IP booting time considerably.
Q: Video response seems slower in limited bandwidth condition, are there ways to
increase the response speed?
A : There are several ways to increase the response speed on the viewer screen:
(1) Under bandwidth limited condition, you should select a more economical encoding scheme
such as Slow Internet or Fast Internet Encoding scheme instead of the LAN or No
Compression Encoding scheme from the viewer connection option menu. However, if the
connection is made only within LAN with plenty connection bandwidth, LAN or No
Compression Encoding scheme should be (paradoxically) quicker than Internet scheme –
since your client computer won’t dissipate extra computing power for decoding the more-
compressed internet scheme.
(2) Use 8-bit color reduction (with only 256 colors instead of the 65K colors in 16-bit settings).
(3) You can enable Automatic Filter Adjustment (Web Management/Video Server page) for
automatic video optimization according to different bandwidth condition.
(4) On the other hand, if you don’t want to use Automatic Filter Adjustment, you could
always select either Medium Quality/Low Quality level for more speed as your Video
Filter setting (Web Management/ Video Server Page). You could also do something to
increase the response speed: use a server desktop of small resolution (such as 800 x 600)
and use a solid plain color background for server desktop.
(5) Finally, you should check also the networking environment to find if there is some
bottleneck that can be improved or eliminated for more bandwidth throughput.
Q. When connection is first made, the display on the viewer screen seems not
centered correctly and there is black margin on the edge of the viewer screen. How
could I eliminate the black strip?
A. The black strip is the offset that will be seen when the display on viewer screen is not
centered corrected. Probably you have not enabled automatic centering option on Prima IP,
so please check the followings:
When the viewer connection is made, select the Adjust Screen option on Viewer’s Quick
Menu, and the Adjust Screen dialog box appears. On it, check whether you have Automatic
Centering enabled. If it is not yet enabled, please check this option to enable it. If it is
already checked, please uncheck it and then wait for at least 15 seconds and then check the
option again to force the video server to align (center) the display in the viewer screen.
