Multiplex
DVB-T (Digital Video Broadcasting - Terrestrial) is broadcast in groups of channels on one
common frequency. This arrangement is known as a Multiplex.
There are several multiplexes in the DVB-T system, each carrying a group of channels.
If the signal level on a particular multiplex frequency is poor you may lose the whole group
of channels on that multiplex.
Digital Terrestrial TV Troubleshooter
Possible causes
Weak signal or wrong type of
aerial.
Not receiving one or more
digital multiplex frequencies.
Interference or other problem
caused by passing aerial signal
through other equipment.
What to do
Try re-tuning.
Aerial may not be suitable for digital TV broadcasts.
You may be in a place which does not get a good digital TV
signal.
Get an aerial rigger to check the aerial system.
Try connecting the aerial directly to the digital TV receiver
and then re-tuning.
If some equipment has a radio frequency modulator, switch
it off or change the frequency of it and re-tune the analogue
TV. (Please see other equipments instructions for how to
do this.)
