Remarks on DVB-T system
DVB-T is at present still being developed. You can get information regarding the current stage of development
on http://www.ueberall-tv.de or from your specialist retailer.
As a digital service DVB-T basically works differently to previous analogue TV reception.
Reception Possibilities:
In contrast to cable TV, DVB-T is received via room or roof antennas. A room antenna is sufficient for reception
within the reception area of a DVB-T transmitter. A roof antenna may perhaps be necessary for reception in a
fringe area. Existing roof antennas may have to be turned in a different direction.
Contact your specialist retailer or go to http://www.ueberall-tv.de to find out about the location of the reception
areas or fringe areas. You cannot get DVB-T reception outside the fringe area. Ask a certified antenna specialist
for advice on interference with reception. The tuner of this appliance cannot provide active room antennas with
operating voltage. Active room antennas have to be equipped with a separate power supply.
Reception Quality:
DVB-T reception principally either works really well or not at all. There is not a smooth transition with a constant
reduction in reception quality. Digital interference occurs at maximum reception range:
the image freezes, the picture becomes blocky, the sound breaks up or reception cuts out altogether at times. If
you notice interference with DVB-T reception then this is usually not due to a fault on the TV appliance. Please
contact an antenna specialist if you have interference with reception. Inspection of the quality of DVB-T reception
is not included in the free warranty to be provided by the manufacturer of the TV appliance.
Image and Sound Quality:
An individual transmitter transmits up to 4 TV channels on one transmission frequency. This is possible through
compression in accordance with the MPEG standard, which is similar to digital data storage on a DVD. The
data rate of DVB-T is just a lot lower; at present the max. video bit rate is approx. 4Mbps and the max. audio bit
rate is at 256kbps. Visible interference (e.g. blocky picture) can result at extremely low data rates despite there
being excellent reception quality within vicinity of the transmitter. Blocky pictures are no fault of the receiver.
They are the result of the low data rate transmitted. The digital DVB-T sound can be transmitted to the digital
amplifier via the digital output of your TV set.
Image Format
Images are transmitted in 4:3 format, 4:3 letterbox format (with black bars above and below the picture) and
anamorphic 16:9 format (without black bars). The max. transmitted resolution at present is 704x576.
Encryption
Encryption is basically possible, but no DVB-T channels are as yet encrypted. A CAM module and an access
card are necessary to receive encrypted channels. You can get CAM modules from your specialist retailer and
access cards from the respective broadcasting company. The CI slot in this appliance accepts CAM modules
and therefore allows for the reception of encrypted channels. Please note: Pay TV providers are basically free
to choose their encryption system. Although this TV set is manufactured according to DVB standards, it can
be that a set-top box is nevertheless required to receive the desired pay TV channels. These are available
from the pay TV provider.
Child Lock
Like DVDs, DVB-T offers can also provide age-restricted access. At the moment, no channels are equipped
with this restriction. This appliance does, however, already offer the feature of setting up password protected
age restrictions, which only work when the respective programmes are broadcast.
EPG (Electronic Program Guide)
EPG is part of the DVB-T-signal with 8-days-schedule. This TV can receive and display the EPG-information
included into DVB-T. This TV’s EPG-Decoder will not work with cable- and Satellite-TV.
