Abstract
A head station including at least two identical processing units supplied respectively with at least one identical input datastream in order to generate an output datastream, and an output bus system connected to the processing units for the exchange of output datastreams and status data generated in each of the processing units is provided. Additionally, within the head station, several decision circuits connected to the output bus system are provided for the selection of the output datastream to be transmitted in each processing unit in each case to a transmitter system.
Claims24
A head station comprising:
- at least two identical processing units, which are each supplied with at least one identical input datastream and generate an output datastream;
- an output bus system connected to the processing units for an exchange of output datastreams and status data generated in the processing units respectively;
- and
- at least one decision circuit connected to the output bus system in order to select the output datastream in each processing unit to be transmitted respectively to a transmitter system.
A method for selecting an output datastream to be transmitted respectively in identical processing units of a head station, in each case to a transmitter system, comprising:
- generating an output datastream in every processing unit from at least one of an input datastream supplied to each processing unit;
- exchanging the output datastreams and status data generated in each of the processing units via an output bus system connected to the processing units;
- selecting the output datastream to be transmitted in each processing unit to the transmitter system by at least one decision circuit connected to an output bus system;
- and
- transmitting the output datastream selected respectively for each processing unit to the transmitter system.
