Primary distribution of digital terrestrial TV via satellite
How does a TV signal get to your digital TV set?
Television and radio content is sent from a central hub over a satellite link towards transmitter towers. Digital TV sets receive their signal from these transmitter towers and repeaters. Horizon equipment is installed in the transmitter towers
To ensure excellent mobile reception Horizon combines broadcast standards and innovative technologies.
- Several digital programs are typically multiplexed together on one terrestrial carrier and many networks distribute several networks simultaneously.
- As UHF and VHF terrestrial frequencies are very sparse resources. The same frequency is often used by all towers in the network (Single Frequency networks).
- Through a GPS-timing function all towers transmit exactly the same information in a fully synchronised way in order to prevent interference between two adjacent towers.
What is critical in the deployment a broadcast network?
- Time-frame in which the new network needs to be deployed
- The CAPEX and OPEX costs of the primary distribution network
- Space and power consumption issues of the equipment in the towers
- Reliability of the equipment and remote management of unmanned isolated sites
- Broadcast of local content and local advertising
- Good reception without interference for the end-user
Horizon provides an answer to the challenges of Mobile TV operators
Why satellite?
- No need for telecom infrastructure on the ground
- Satellite is the fastest way to deploy a DTT-network over an entire country.
- With the right technology and equipment, satellite is a very economical way to perform the primary distribution of TV content.
- The operational costs do not increase with the number of towers and repeaters in the network.
- Satellite provides very efficient methods to synchronize and manage towers remotely.
