In order for it to work
well, several things have to be working properly.
1. Fiber from NOC to your school (most likely this works all or none).
2. You campus LAN needs to be working properly (a place for problems).
3. The LAN needs to be working at 100 megs not 10 megs.
4. The computer network card needs to be set at 100 megs, not 10 megs.
5. The computer needs to be plugged into the wall/pole socket, not a
hub.
6. The line that the computer is connected to needs to be connected to
a switch in the IDF or MDF, not a Hub.
7. The computer needs to be new enough and fast enough to handle the
necessary speed. (most of the Dells [i.e. new] seem to be running just
fine).
Try this:
Click Windows Media Player

When
trying to use Digital Curriculum with a desktop model, WIN 98 and
projector/TV
1. Minimize any open programs and show desktop.
2. RIGHT click on "My Computer".
3. Click on "Properties".
4. Click on "Performance" tab.
5. Click on "Graphics" button.
6. Change hardware acceleration from "full" to
"none".
7. Click OK & restart the computer.

is possible that this same procedure will work on the laptopss, or
other desktops with XP, but it has been tested on desktop model
with WIN 98! |

When
trying to use Digital Curriculum with a laptop ( or possibly a desk
model) and projector/TV
1. Hold down the FN key (it is located next to the Ctrl key on the
left or in some cases it may be the "Windows"-floating box
key)
2. While holding down the FN key, press F8. The image should move to
the projection screen. Press F8 again and the image should show in
both places. You may need to press F8 one more time.
Quite often because
of an issue with Dig Curr.. the projector will attempt to show the
image in both places and does not have enough "power" to
push the signal forward in both places. You can test this
problem by bringing up a REGULAR webpage and toggling at least 3
times. You will see your image from the regular webpage one time on
the computer only, one time on the big screen only, and one time in
both places. That indicates you are hooked up correctly. It is still
possible that the video streaming from Dig. Curr. will NOT project
in both places at the same time! |

had to update to the latest media player
in order to make it work.
I checked the computers in library I
installed some needed updates and changed some settings to the
computers and they are now all working.

Title: |
Video does not appear when using a projector or
large screen monitor/LCD/TV. |
|
Last Updated: |
Thursday July 29, 2004 |
|
|
Symptom:
When connecting my computer to a projector or a large-screen
monitor/LCD/TV, I can see everything except for the video. |
|
|
Cause:
This behavior is noticed mostly on Notebooks/Laptop computers
connected to projectors or when trying to display the video on a large
screen TV using a video-out capable card in Windows Operating System.
There are several possbibilites that are causing this behavior:
-
The video card is unable to drive both displays -- the computer
display and the projected display.
-
Old or outdated Video card drivers are installed.
-
Old or outdated version of DirectX is installed.
|
|
|
Resolution:
To correct this issue:
-
The quickest way to resolve this issue is to consult your hardware
manual or contact your hardware vendor for instructions that will
allow you to disable your notebook/laptop display while keeping the
projected display enabled.
-
In some cases video drivers for that video card/display device must
be updated to correct this issue.
Contact your hardware vendor to obtain the latest drivers
-
DirectX for Windows MUST be updated to the latest version.
Download and install the latest version of DirectX supported by your
version of Windows. Please visit
this page for further information and download instructions.
In very rare cases, mostly in desktop configurations and/or using
video-out cards, if the issue still exists, one or all of these steps
needed to be followed:
-
Disable hardware acceleration for Windows:
Windows 98/ME users:
1. Right-click the My Computer icon on your desktop and then then
select Properties.
2. Click the Performance tab at the top.
3. Click on the Graphics button at the bottom.
4. You probably will see your hardware acceleration set to Full.
Slide the pointer to None, and then click OK
5. Restart your computer.
Windows 2000/XP users:
1. Right-click on any blank spot on your desktop, and then choose
Properties.
2. Click the Settings tab, and then click Advanced.
3. Click the Troubleshooting tab.
4. Move the Hardware acceleration slider to None.
5. Click OK to accept the new setting, and then click OK to close
the Display Properties window.
6. Restart Windows.
-
Disable hardware acceleration using DirectX diagnostic tool (if the
above was not possible):
1. Quit all running programs.
2. Type dxdiag and then click OK.
3. The DirectX diagnostic tool should now be running on your
desktop; Click the Display tab.
4. Disable DirectDraw Acceleration and Direct3D Acceleration.
This will put video on the same layer with the rest of your display,
which might help buggy video card drivers to drive multi-layered,
multi-frequency-based screens to be displayed properly.
Remember to change things back when your presentation is finished.

Hardware acceleration slider set to none in
computer’s Display settings did the trick. The video acceleration located
in Options when you right click on the actual streaming Windows Media
screen being set to none does not correct the problem.
Comments:
Computers may have to be traced to which drop they are connected to
then all the drops may have to be matched to the switch port they are
connected to in the closet. Then, an inventory of each switch IP address
must be gathered and then each computer's network controller must be
reconfigured to run at the 100 / Full duplex mode. Some computers will be
able and some won't.
Any
"mini-hub" connected computers will not work well at all. There are also
other programs that might need to be installed such as Acrobat Reader 5.5 and
Media Player. Then the local resources of each computer may be an issue as well.
I am not sure that the memory is the problem so much as the
processing speed. New fast computers seem to work. Old slow computers
do not. You almost just have to try them and see.
Older computers just doesn't have enough RAM
to properly buffer the video.
On the new Dells that the teachers have,
there seems to be fewer problems.
If you put the Windows Media Player on the Desktop as
directed in the online instructions, it works fine. |
Pick 1 or 2 teachers (Science or Social
Studies)
Show them how to:
1. Log on (link now on Library Resources Page).
2. Search (I would start with the curriculum standard [TEKS] search, see
one below).
3. Show Teacher's Guide
later:
4. How to make a hyperlink
Example search to help you get started:
1. From the Library Resources Page, click on the Digital Curriculum link
2. Click the login
button. (if you are logging in at the student level you just need to
click the Login button without typing the username and password
within the district).
3. In the Username box type the
username
4. In the Password box type the
password. |

FYI
This morning, I was able to restore Digital
Curriculum video streaming on a 5th grade Win98 computer that
stopped streaming after Thanksgiving. I’m unsure what the exact fix was,
but after I installed Windows Media Player v.9, reduced the video
acceleration setting, and configured RSTP proxy settings for
168.69.253.149, port 554, it worked.
