Abstract:
1. A device comprising: receiving means for receiving a modulated carrier signal which contains an encoded data signal, said encoded data signal including decoding instruction information; the decoding means including at least a first physical decoding stage and a second physical decoding stage, the first decoding stage being arranged to decode said data signal encoded in conformity with a first decoding method whereas the second decoding stage is arranged to decode said data signal encoded in conformity with a second decoding method, and wherein said first decoding method is Manchester (MA) and the second decoding method is Miller; and wherein said decoding means further includes a decision stage capable of determining based on said decoding instruction information which of the first and second decoding stages is suitable to decode decodes the encoded data signal, and wherein the decoding stage information includes redundancy data.
