A METHOD AND CIRCUIT ARRANGEMENT FOR MULTIPLEXING DIGITAL DATA STREAMS TO FORM A DIGITAL OVERALL DATA STREAM AND FOR DEMULTIPLEXING A DIGITAL OVERALL DATA STREAM TO FORM DIGITAL DATA STREAMS

摘要

Method and arrangement for multiplexing a multiplicity of digital data streams to form a digital overall data stream, as well as a method and arrangement for demultiplexing a digital overall data stream to form a multiplicity of digital data streams. When multiplexing data streams (DS), the data streams are grouped to form digital intermediate data streams (ZDS) . The grouping is carried out in such a manner that identical data streams (DS) are jointly grouped to form an intermediate data stream (ZDS) and different data streams (DS) are grouped into different intermediate data streams (ZDS) . Measures for error identification and/or error correction of the intermediate data stream (ZDS) are carried out for the intermediate data streams (ZDS) . Finally, the intermediate data streams (ZDS) are grouped to form the overall data stream (GDS).
