5. PRACTICAL EXAMPLES OF SYSTEMS DTTV
The owner of a hotel in Menorca, Mr. Ferrer, wants to give the hotel a touch of
distinction over the competition, so he has decided to install flat TV screens with built in
DTT tuner in each room and a satellite dish. He wants an installation of digital quality,
but without spending too much money and using the analog distribution network already
installed. He also wants to add some international channels to the TV services, in
addition to the national ones already available, because often there are Italian and
German customers. How can the system
DTTV fulfill his wishes? Read next...
1.- Current infrastructure.
Firstly, it should be clear to you the purpose of your installation and the
existing telecommunications infrastructure in your establishment. In this
specific case:
- Analogue TV Distribution network via coaxial cable.
- DTT receivers with built-in tuner.
- Satellite dish.
- Terrestrial antenna receiving digital and analogue signal.
2.- TV Services to distribute.
You should decide what channels and services you want to distribute at your
hotel. In this specific case:
- All national DTT channels.
- Two Italian satellite channels (Canale 50 and TV7 Lombardia).
- Two German satellite channels (Das Erste and RTL 2 Schweiz).
3.- With these initial data, you can get an idea of what you need for your DTTV
installation.
- To tune 2 channels of different frequencies, you need a dual receiver,
therefore, use a
DT-302 .
- To convert 2 signals to digital, you need a DT-102 .
- To combine the resulting signals and obtain a single output, you need a
combiner
DT-710 .
