2.3 Description
The COFDM AV module HDCT 460 AV, in the following called digital module, has
a COFDM AV converter which simultaneously converts four COFDM modulated
channels into AV signals using two DVB-T tuners.
The digital module has two DVB-T inputs. Via the AV interface, the decoded
video and audio signals are fed to the corresponding modulator module. From
there, they are fed to the HF output collector of the head-end station, through
which the level of the output signal can be adjusted via the software in the
head-end station.
The channel strips “
A ” “ B ”, “ C ” and “ D ” can be individually programmed. This
means it is possible to select up to 4 channels out of two data streams. The fol-
lowing table shows the allocation of the selectable number of channels to the
tuners:
Tuner “A” Tuner “D”
Number of
channels
3 1
2 2
For example, if three channels from tuner “A” will be used, one channel from
tuner “D” can be used. If two channels from tuner “A” will be used, two chan-
nels from tuner “D” can also be used.
Signal transfer principle:
The operating software of the digital module can be updated via the 9-
pin SUB-D socket on the control unit of the head-end station using a PC or
notebook and the Software “
BE-Flash ”. You can find the current operating
software on the website “

This digital module is designed exclusively for use in the STC 160 head-end
station.
