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 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.
