6. Tips @ tricks for the TV module
The TV module of Site@School is a simple solution to have a kind of message board via a TV set.
The TV module enables you to update pages on the TV set.
You can have, for example, an old TV in the hall of the school to display messages, pictures, etc.
Multiple TV sets can be controlled via the TV module.
To do this, for every location in school where you have a TV set, you need the following materials:
- Some computer with an OS (Linux, Mac, Windows) connected to the school network.
- A web browser installed on the OS (Firefox, Netscape, Safari, Internet Explorer, etc), set to 'Kiosk' mode. In the Kiosk mode the browser has no title bar, no toolbars or menus, no status bar and displays its content full-screen.
- A TV output on the computer. This is mostly done with a cheap monitor/TV card (also known as a scan converter). In this way you can attach a monitor and a TV set to the computer.
- A TV set that can accept the output from the TV card. Make sure the combination of TV set and TV card works appropriately.
- Of course it's also possible to use a flat screen monitor instead of a TV. A flat screen can be connected directly to the computer.
The TV module of Site@School can show pages of S@S in these ways:
- Show multiple S@S pages.
- Show one vertically scrolling page.
- Show an album page from the ALLbum module in a slideshow fashion.
- Show one Site@School page.

The TV module is now part of the Site@School v. 2.4 installation.
If you are migrating from an earlier S@S release, it has to be installed separately.
Point your browser to: http://www.yourschool.org/starnet/install/install_tvmodule.php.
The URL is fictional, replace the 'www.yourschool.org' part with the URL of your school.
Follow the onscreen instructions.
With a few mouse clicks the database tables are created and the TV module is installed on your system.

Before you can use the TV module, you must add pages to it and you must prepare the computer's TV card.
The procedure to add pages slightly differs from the other modules. In the next section the adding of pages and scripts is discussed.
Preparing the computer is treated in 5. Your TV pages on the TV set
(top)
The TV module uses 'scripts' to show pages on the TV set(s). These pages must be selected.
When you click on 'Module manager' > 'TV module', you will see:
![[TV module opening ]](pics/mod_tv_open.png)
mod_tv_open.png
When you click on the dropdown menu, you will see the available scripts:
- Page slideshow: Displays separate pages in a certain order and time.
- Scrollscript: Displays one vertically scrolling page.
- Slideshow: Displays an album page created with the ALLbum module in a slideshow fashion.
- Showpage: Displays one page.
Select one of the desired scripts. The scripts are discussed below.
Now you will see:
![[TV module: script added ]](pics/mod_tv_script_added.png)
mod_tv_script_added.png
Explanation:
- Trash can icon: Click to delete an entry.
- View page icon: Click to view the page as it is displayed on the TV set.
This is useful to check whether you have made the correct choices in the configuration.
- (n): Location identifier. When having more TV sets in your school, you can specify on which TV set the page will be displayed.
For configuration, see below.
- Script name: Now it shows the selected script name. Can be changed in configuration, see below.
NOTICE: At this moment these scripts are available. These scripts are discussed in:
4.1 Page slideshow configuration

The selected script must be configured. To do so, click on the script name. The configuration window will open.
We will now discuss each script's configuration options.
When you have chosen the 'Page slideshow' script and you click on its name, you will see:

![[ ]](pics/mod_tv_example.jpg)
mod_tv_example.jpg
A school with two TV sets; one for the Kindergarten entrance (location id = 0) and one for the entrance of the other groups (location id = 1).
(top)
The browser which you use to display the TV pages has to be configured to run in 'Kiosk' mode.
This means that no menu bar, buttons, etc. are displayed and the browser displays its content full screen.
Here are some links that describe Kiosk mode for various browsers:
Opera: http://www.opera.com/support/mastering/kiosk/
Mozilla: http://tln.lib.mi.us/~amutch/pro/mozilla/kioskmode.htm
Firefox: http://tln.lib.mi.us/~amutch/pro/phoenix/kiosk.htm
K-Meleon: http://tln.lib.mi.us/~amutch/pro/kmeleon/
This is a special library browser that seems particularly suited for the TV module.
Internet Explorer: http://support.microsoft.com/?kbid=154780
These are the steps to prepare a Windows OS and Internet Explorer for the TV module:
- Open 'My Computer', go to 'Scheduled tasks' and click on 'Add Scheduled Task'.
- The 'Scheduled Task Wizard' window opens. Click 'Next'.
- A menu opens. Select 'Internet Explorer'. Click 'Next'.
- A new window opens and you can select when IE should start. Select 'When my computer starts'. Click 'Next'.
- A new window opens. Select 'Open advanced properties... etc.'. Click 'Finish'
- The 'Scheduled Task Wizard' closes and
- a new window opens: 'Internet Explorer'. It has three tabs.
- Select the 'Schedule' tab and check if the selection in the dropdown menu is on 'At system start-up'.
- Select the 'Settings' tab and deselect the option 'Stop the task if it runs for 72 hours 0 minutes'.
- Click on 'OK' at the bottom of the window.
- You are back at the 'Scheduled Tasks' opening screen. The 'Internet Explorer' icon is visible.
- Right click with your mouse on the 'IE' icon. A menu opens, select 'Properties'.
- A window opens. At 'Run' you will see: C:\PROGRA~1\INTERN~1\IEXPLORER.EXE
- Add this behind the above line: -k. This is the 'Kiosk' mode option. So, now you have:
C:\PROGRA~1\INTERN~1\IEXPLORER.EXE -k
- In the bottom of the window click on 'OK'. The window will close,
- Also close the 'Scheduled tasks' window.
- Restart the computer.
- The computer should now start with IE in Kiosk mode.
What remains is: adding the right URL and location identifier to the browser and set this URL as the default start URL.
The URL is:
http://www.yourschoolsite.org/starnet/addons/tv.php?loc_id=n
|
Where 'n' is the location identifier. When you have one TV set, its value is probably '0', without quotes.
Make this URL the home page of the used browser.
You can remotely change the script to another one, the tv.php script will check every 60 seconds for a change.
Good luck with your TV module.
