What is a disrupted reception in digital ?
In digital reception, a disrupted reception results in frozen pictures
(partially or totally), or the appearance of mosaic effect. The sound may disappear
for a while, or strange effect can be heard. The consequences are totally
different from the consequence in analogue (snow effect).
What about indoor reception ?
The transmission parameters are not optimised for indoor reception. As a
consequence, even though it is possible to receiver Freeview channels with
an indoor antenna, it is never guaranteed. Coverage areas are dened for
a roof-aerial. Indoor reception is only possible at a short distance from the
transmitter. In this case, electronic noise from home appliances
(washing machines, switches, ...) often causes eeting reception problems.
