The above Joey Lite example layout might typically be used in a classroom situation with an installed projector and Combo DVD/VCR player connected to a TV system. The user would activate the installation by pressing the source they wish to use.
Pressing DVD would:
1. Activate the roof mounted projector
2. Put the projector into DVD mode (typically S-Video input)
3. Lower the screen if it was motorised
4. Place the Combo DVD/VCR into DVD mode
The system would then be ready for the user to use. From here the user could navigate the DVD Menu using the 'arrow keys' and 'enter'. They could even just go straight to 'play' and play the DVD.
Volume control is there ready for them to raise and lower the volume as needed. The operator might have a laptop plugged in also and could simply press the 'PC1' icon to switch from DVD to the laptop. From this oint the user might press the 'tv' icon which would switch the projector to the Combo DVD/VCR's composite video input and place the DVD/VCR into tuner mode. The 'up' and 'down' arrows would then become the channel change buttons.
Typically DIB Australia would offer the customer the option of including 'AV Mute' buttons which would also blank the projector screen as required from time to time.
The example above also includes manual screen 'raise' and 'lower' buttons. |
