ABSTRACT:
A receiver and a method for adding a sequence, embedded in a digital sequence of data together with another sequence, separate of the other sequence to at least a part of the digital sequence of data. An example of such a sequence is the Program Associated Data (PAD) in a DAB digital sequence of data, this PAD being embedded in audio frames together with audio data. The DAB digital sequence of data is converted into a sequence according to the IEC958 format, wherein the retrieved PAD is inserted into the User Data channel in the IEC958 frames. This allows an easy retrieval of the PAD from the digital sequence of data, without the need for analyzing audio frames and retrieving the PAD therefrom.
