Abstract

In a data stream individually encoded data stream (ds1 . . . n), data packets formed as key data packets (sp1 . . . n) are to be inserted, with which the data stream-individual key information (si1 . . . n) is transmitted with the associated data stream (ds1 . . . n). For analyzing and/or recording, at least one key data packet (sp1 . . . n) is searched for in the associated data stream (ds1 . . . n), and the data stream-individual key information (si1 . . . n) is determined. By means of the data stream-individual key information (si1 . . . n), the associated data stream (ds1 . . . n) is decoded. The generation and insertion of key information (si1 . . . n) can be achieved with minor administrative effort, thus considerably reducing the effort for the analysis or diagnosis (ds1 . . . n) of the simultaneously transmitted, encoded data streams (ds1 . . . n). Advantageously, the insertion of key data packets can only be activated or initiated if the diagnosis or analysis and/or recording of the data streams is currently carried out.
