DIGITAL TV HEADEND
1. GENERAL
1.1 Description
The DTTV system (Digital to TV) is based on a TV headend that receives
television signals from different sources. It processes them for its integration into an
output signal in Digital Terrestrial (DVB-T) format.
In this way, the signal can be distributed on a TV network with multiple receivers,
keeping the original wiring installation but distributing in high-quality format. This system
is applicable to hotels, hospitals, shopping centers, universities, etc. that is, local
distribution networks that want to distribute content in digital quality.
DT-800 is the control and power module, therefore is the most important module
of the DTTV system. The DT-800 controls the DTTV headend, which would be made up
to a maximum of seven modules. Two cable bus connect the control module to the
other modules of the headend. The DT-800 allows individual control and configuration
of each module.
The user can manage the DT-800 in two different ways: in local mode or in
remote mode. In local mode, the module is managed via the keypad and the LCD
screen placed on the frontal. In remote mode, the control module is connected to a
computer through a network cable and is managed by using the specific software
control (RM).

3. INSTALLATION
3.1 DT-900 Sub-rack
The DT-900 is a metallic casing (sub-rack), where the DTTV modules are
installed (Fig. 1).
Supplied accessories allow the subrack to be set up in two ways: Installing it in a
19 " rack cabinet (Fig. 2) or anchoring it on a wall.
The wall anchoring system allows, through a tilting system, accessing the rear of
the subrack, where the connectors are placed (Fig. 3).
One subrack can contain up to 8 modules. One of them must be the control
module DT-800.
The sub-rack DT-900 is supplied with an user’s manual, which describes in detail
the steps to complete the assembly.
