2. Use and operation of the MegaVideo 55
The MegaVideo55 is a programmable stereo modulator that converts audio and video signals
from, for instance, your DVD player, satellite receiver, video recorder, security camera, decoder
or PC and adds it to your aerial cable as an extra channel. Then you can receive this signal as
a kind of internal TV channel anywhere in the house where you have an aerial connection.
You could say that the modulator is “looped into” the aerial signal. The incoming aerial signal is
connected to the aerial input. The audio/video signal (from a DVD player for instance) is added
to the outgoing aerial signal. The added video signal can now be viewed on the channel that
has been set on any televisions that are connected after the modulator (on the ‘RF ANT OUT'
side of your MegaVideo 55). You do not need to change any other part of your aerial network.
Thanks to the built-in “infrared return channel” you can continue to operate the connected
appliances from other rooms using your own remote control. One infrared receiver is supplied
as standard. Additional receivers can be purchased should you wish to operate your
equipment from different rooms.
The infrared return channel only works with amplifiers, splitters and aerial wall outlets that
are return channel compatible. Compatible components are usually marked ‘5 – 30 MHz’ or
‘5 – 68 MHz’. Your aerial specialist can provide more information on this.
The modulator itself has no effect on the signal strength. The maximum length of cable that
