Abstract

Verfahren zur Synchronisation eines Rundfunkempfängers, der in einem Rundfunksystem arbeitet, bei welchem neben dem eigentlichen Programm zusätzliche Informationen wie beispielsweise ein Programmidentifizierungs-(PI-)Code in Form eines seriell übertragenen binären Datenstromes übertragen werden, wobei der Datenstrom (1) in einzelne Blöcke (3) unterteilt ist, die neben einem sogenannten Offsetwort (4) jeweils ein Nutzwort (5) enthalten, insbesondere eines Rundfunkdatensystem-(RDS-)Empfängers auf den empfangenen Datenstrom (1), indem der empfangene Datenstrom (1) auf das Vorhandensein einer bekannten Bit-Folge (7) untersucht wird, wobei zur Beschleunigung des Synchronisationsvorganges wenigstens ein Teil eines erwarteten Nutzworts (5) zur Synchronisation verwendet wird, indem der Datenstrom (1) zumindest auch auf das Vorhandensein der Bit-Folge des erwarteten Nutzwortes (5) oder Nutzwortteiles untersucht wird.

Method for synchronizing a radio receiver that works in a radio system, in which, in addition to the actual program, additional information such as a program identification (PI) code is transmitted in the form of a serially transmitted binary data stream, the data stream (1) being divided into individual blocks ( 3) which, in addition to a so-called offset word (4), each contain a useful word (5), in particular a radio data system (RDS) receiver on the received data stream (1), in that the received data stream (1) indicates the presence of a known one Bit sequence (7) is examined, at least part of an expected useful word (5) being used for synchronization to accelerate the synchronization process, in that the data stream (1) at least also for the presence of the bit sequence of the expected useful word (5) or Useful word part is examined.
