Ensemble transport interface signal transforming method, involves adding information block in connection to fast information blocks for forming ensemble transport interface signals in digital audio broadcasting mode

摘要

The method involves adding an information block (30) in connection to fast information blocks (FIB1-FIB3) for forming ensemble transport interface (ETI) signals in a digital audio broadcasting mode. The ETI signals are provided with the fast information blocks with a length of 256 bits. The information block in connection to an end marker field is filled by padding until the 256 bits with cyclic redundancy check (CRC)-fields are obtained, where the information block is designed as a dummy-information block. The CRC is executed at an end of the information block. An independent claim is also included for a device for transforming an ensemble transport interface (ETI) signal in a digital audio broadcasting mode (DAB) into another DAB mode.
