DVB-S systems
DVB-S is a digital transmission of audio, video and data streams using sattelites. The program boucket is generated in the up-link station (place of base information generation) from which it is transmitted to satellite transponders retransmitting the signal to appointed geographical regions. Thanks to this solution the transmitted programs can be received by:
Digital compression gives the following advantages:
VECTOR offers turn-key solutions including hardware, software and technical support starting with design of the solution, implementation of the system, integration with operator's systems and network and ending with system maintenance and support during its normal operation.
- individual users having satellite reception sets containing an antenna with a frequency converter and a receiver
- cable TV operators who, depending on the subscriber needs, enter radio and TV channels into a network
- regional terrestrial retransmitting stations broadcasting the signals to the subscribers Due to digital satellite transmission of radio and TV programs it is possible
- to increase transmission efficiency thanks to sending radio and TV programs of several times higher number than in case of analog satellite transmission
- to broaden service offer thanks to adding new multimedia services
- to reduce capital and operational expenditures connected with building and maintenance of only one transmitting station
- to increase the subscriber number thanks to better coverage than terrestrial TV.
Digital compression gives the following advantages:
- more effective usage of transmission network - with the same bandwidth we can send much more information
- improvement of the transmitted data (signal) safety thanks to encoding process.
