Picture Quality
The picture quality by DVB-T depends on the different areas and the different conditions. Some
parameters are important for the picture quality, the bit rates, the resolution and the reception of the
transmitted DVB-T signals.
Bit rate
The bit rates is fixed by the TV broadcaster and can be different between each TV program. Also the
different TV broadcaster define the bit rate different to each others. If you see by watching DVB-T
strong mosaics structures, artefacts or an un sharp picture, than you can try to increase the Signal
strength and Signal quality by searching a better position of the indoor aerial. Maybe you can try also
to change a passive indoor aerial to an active indoor aerial. But, if you can realizes optimal condition
by receiving the DVB-T signals and you have anymore the artefacts or mosaics structures, than is the
transmitted bit rates to low.
In Germany the values are very different by the bit rates:
ZDF
ARD
HR
Private TV Stations
If the bit rate is higher, than the picture quality is mostly better and the picture is more than less by
artefacts or mosaic structures.
Resolution
The second influence by the picture quality is the transmitted resolution. If the resolution is higher
than you can see a more sharper picture. For example:
ARD / ZDF
Other
Receiving Condition
If you see by the information Signal strength and Signal quality some low values, you can try to find
another antenna position to increases the reception quality. Visible indicators for a worst reception of
the DVB-T signals is for example the a freeze picture or the message "No Signal".
The reception quality depends for example on the kind of the antenna. Three different kind of antenna
are available, the passive and active indoor aerial and the roof antenna. Realign your indoor aerial in
this way, that you get the best reception as possible. Helpfully it to know in which direction are the
public antenna power and than you can adjust the antenna to this direction.
If a passive indoor aerial can not receive the DVB-T signal strong enough, please try an active indoor
aerial. The best reception results are by the roof antenna possible.
