Classroom Multimedia

Every ESSD40 classroom is equipped with a multimedia system that provides audio-visual capability.

For grades K - 5, the system includes an interactive white board (e.g. SMARTboard), LCD or LED projector, a sound amplification system with ceiling- or wall-mounted speakers, and an Apple TV.

For grade 6 - 12, the system is a large-format LCD TV and an Apple TV.  A small number of rooms have a legacy interactive whiteboard, projector and sound amplification system.

This blog page is intended to provide an overview of these systems that will help the classroom teacher operate these systems and possibly troubleshoot issues quickly without the delay of requesting Technology Department assistance.




Interactive Whiteboard Systems


The more you know, the better you can pinpoint problems which leads to faster resolution.  Here's a brief tour of the components.

Types of IWB Systems in the District

In general, the district IWB systems are in two categories.







The "all-in-one".








The "separated".











Regardless of the system, IWB systems have three major components:  the interactive whiteboard, the projector, and the audio amplification system.  The district IWB systems also include an Apple TV.

The Interactive Whiteboard

The whiteboard itself is a giant mouse to control the computer--hence the "interactive" part of the name.  For more information see this webpage.

Any image displayed on the IWB is not utilizing the interactivity capability of the IWB.  Only when touching the board and controlling the computer is one truly using the IWB as an interactive device.

The Projector

The visual display on the IWB is not a function of the whiteboard, but of the projector.  So if the visual is not displaying properly, the issue resides with the projector not the IWB, a common misconception with all IWB users.

View this video from SMART about troubleshooting SMART projectors.  

Input Selection

Technically, input selection isn't a component in the literal sense because it is a function of the projector.  But the importance of input selection and the manner in which it occurs in our IWB systems is such that a separate discussion is warranted.

All-in-one IWB systems have an input selector near or attached to the IWB.  Use this to change the display input of the projector from the computer to other attached devices such as an Apple TV or DVD/Blu-Ray player.










Separated IWB systems where the projector is not attached to an arm coming from the IWB but are mounted to the ceiling come in two flavors, 1) multiple input projectors and 2) single input projectors with a VGA switch.


Multiple Input Projectors

Multiple input projectors like the one at right have more than one VGA inputs and possibly an HDMI input.  The example at right has only two VGA inputs.  With these projectors, input selection is controlled either with the projector remote or by using control buttons on the projector.  Considering how high some of these projectors can be installed, keeping track of the remote is sometimes critical.  Check with the building media specialist if the projector remote cannot be located.


 Single Input Projectors


Single input projectors like the one at right have only one VGA input.  An additional VGA switch has been added to allow display of the Apple TV.  Input selection is controlled by two buttons on the VGA switch.







Desktop Display on IWB

What the projector displays on the IWB from the computer is controlled by the computer.  The computer recognizes the projector as a second monitor and must be told what to do with this monitor.

Check these websites for instructions on how to extend the computer desktop display to a second monitor.



Audio

 The audio systems throughout the classrooms can be generally categorized into three groups.  All the systems have audio input from the computer brought in through the wall plate connector usually located just below the amplifier.  On the amplifier itself are additional audio inputs, source selection, and volume control.

For this audio control, input selection is managed by the analog switch just below the volume control.




For this audio control, input selection is managed by a push-button selector labeled "Source Select."  In addition, the volume controls are up/down push-buttons and also includes a Power on/off button.

On a few SMARTboard all-in-one installations, the audio control is included on the control bar of the IWB as shown at right.




Apple TV

An Apple TV is a digital media receiver manufactured by Apple Computer that provides the ability to display content on an iOS device (e.g. iPad) onto the classroom multimedia system using Airplay.  To learn how to mirror the iPad display to the classroom Apple TV, refer to this article from Apple.  District Apple TV's in the Airplay list are named by building and room number.

LCD TV Systems

District LCD/LED TV systems contain two components:  the TV and the remote.  ESSD40 LCD/LED TV systems also include an Apple TV.

TV

For detailed information about the TV's, check the manufacturer's site for the specific model in the classroom.

Desktop Display on TV

What the TV displays from the computer controlled by the computer.  The computer recognizes the TV as a second monitor and must be told what to do with this monitor.

Check these websites for instructions on how to extend the computer desktop display to a second monitor.


Apple TV

An Apple TV is a digital media receiver manufactured by Apple Computer that provides the ability to display content on an iOS device (e.g. iPad) onto the classroom multimedia system using Airplay.  To learn how to mirror the iPad display to the classroom Apple TV, refer to this article from Apple.  District Apple TV's in the Airplay list are named by building and room number.







Troubleshooting


The Technology Department will be updating the information from our Help Request System tickets.

IWB (SMARTboard) Systems

Refer to this page from SMART technologies about troubleshooting IWB's in an all-in-one system.  Contact the building Library Media Specialist for additional help in troubleshooting.

Topic:  SMARTboard on computers with extended desktop setting are not interactive on the SMARTboard itself.
Resolution:  Press the keyboard and mouse icons together to launch orient (or launch it from the SMART tools).  It should appear on the "wrong" monitor, i.e. the desktop/primary monitor.  Press the spacebar which should cause the orientation screen to change to the SMARTboard.  Perform the orientation and you should see it working as expected.

Audio

Topic:  No sound coming from the IWB or LCD/LED TV.
Resolution:  Several possiblities:

  1. Correct input.  
    • IWB's:  Verify that the correct audio source is selected on the amplifier.  (See images above for audio selection switches on amplifiers). 
    • LCD/LED TV's:  Verify the correct input is selected.  VGA is the typical input for the computer.  HDMI is the typical input for the Apple TV.
  2. Muted sound source?  
  3. Check the audio cable connection at the audio source  
    • One end should be connected to the audio out port of the computer.  Or, the audio out of whatever A/V source being used.  
    • The images at right show examples of the computer audio out ports:  one labeled by the manufacturer, one not.  Note:  I have added the "Audio Out" text.
    • Generally, the audio out port is green.  
  4. Check the audio cable connection at the multimedia input panel on the wall.  
    • The audio cable from the computer should be plugged into the port labeled Computer Audio.
    • If another audio source such as a DVD/Blu-Ray player is being used, the "L Audio R" ports are used.
  5. Contact the building Library Media Specialist and Instructional Coach for additional help in troubleshooting.
