Troubleshooting DVB-T
Any problems?
Our custom service will help you. Did you already read the Troubleshooting pages?
No DVB-T Signal
Please check if the unit is in DVB-T mode? If not please switch to this mode.
Bad reception quality?
Please, align your antenna optimally. Use an antenna with active amplifier (house antenna or
roof antenna). If you have moved the unit, adjust the antenna again or connect an
active antenna.
No TV programs?
If there are no more programs shown in the Channel list. Please start the automatic search
again.
Remote control does not work?
Please, direct the remote control upon the device. If the problem continues, please change the
batteries.
Note:
In areas with less DVB-T signals the application of an amplifier is recommended to the
reception of all available TV channels.
Picture Quality
Die 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 rate is fixed by the TV broadcaster and can be different between each TV program.
Also the different TV broadcasters define the bit rate different to each others. If you see by
watching DVB-T strong mosaics structures, artifacts 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 artifacts or mosaics structures, than is the transmitted bit rates to low.
In Germany the values are very different by the bit rates, for example ZDF (2700 until 4500
kbps), ARD (2000 until 4500 kbps), HR (1800 until 3500 kbps) and Private TV Stations (1800
until 2700 kbps). If the bit rate is higher, than the picture quality is mostly better and the picture
is more than less by artifacts 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 sharper picture. For example, ARD / ZDF (720x576 or
704x576 (that‘s PAL Full D1 resolution)) or Other (544x576or 528x576).
