Abstract:
A method for synchronizing two devices with a predeterminable data transmission method from a set of data transmission methods that differ with respect to their error protection for transmitted data, said method comprising:exchanging a first synchronization message and a second synchronization message between respectively a first device and a second device, said first synchronization message having an item of information identifying a data transmission method having a highest-level error protection that can be executed by said first device, said second synchronization message having an item of information identifying a data transmission method having a highest-level error protection that can be executed by said second device; determining said data transmission method of said received first synchronization message at said second device from said received first synchronization message; determining said data transmission method of said received second synchronization message at said first device from said received second synchronization message; forming an additional synchronization message at one of said first and second devices by which said respectively determined data transmission method can be executed, said additional synchronization message identifying said data transmission method that can be executed by both said first device and said second device; sending said additional synchronization message to an-other of said first and second devices; determining said data transmission method of said additional synchronization message at said other of said first and second devices from said additional synchronization message; and synchronizing said first device and said second device with said determined data transmission method.
