The combinatory data linking operation can provide an overall data linking outcome within an individual clock cycle.

The MIFARE applications manager (MAM) is adapted to retrieve MIFARE applications (MIA) from the MIFARE memory (MM), to check whether they meet at least one validity criterion (CRIT1, 5 CRIT2) and to delete those MIFARE applications from the MIFARE memory (MM) that do not meet the validity criterion (CRIT1, CRIT2).

Abstract: In digital mobile broadcast systems, data streams audio and video are sent independently. As this means that both streams may arrive out of sync, they need to be synchronised for reproduction upon reception. For this, the relation between timestamps of both streams should be known. For broadcast, this is difficult because the information is usually not directly available upon the first reception of broadcasted streams and it cannot be send upon playback request. Therefore, the invention proposes to reset counters for generating timestamps upon the start of transmission of the broadcast. The incremental rate of the timestamps can be send on beforehand, as this information usually remains constant over a longer period in time. The invention provides methods for transmission, reception and synchronisation.
