Typical Usage
Imagine the following scenario which occurs
in many households...... Your main TV or sound system is in your
lounge downstairs, together with VCR, Digital decoder box or
Satellite decoder. You have another TV in the bedroom upstairs
but you would really like to be able to watch the satellite channels
on it. Being of an inventive nature, you decide to add an aerial
cable from the decoder downstairs to the TV upstairs. Now you
can watch your favourite video or tv channel from the comfort
of your bed, but someone has to get out of bed and go downstairs
to change the channel or to turn off the VCR.
The solution is to install an infra red
repeater circuit. The circuit receives infra red signals from
the remote control handset and converts them to an electrical
signal. The receiver is installed upstairs and an infra red emitter
is installed in a suitable location within sight of the TV or
VCR downstairs. A simple two wire connection couples the two
devices. Now, from the comfort of your bed, you can use the appropriate
remote control handset to control the VCR or Satellite decoder
which is downstairs! |
