Method and control unit for determining an identification code for an audio data packet

A computer-readable storage medium storing program code for determining an identifiable code for an audio data packet, the program code, when executed by a unit, causing the unit to perform the steps of:

• receiving an audio data stream, and an audio metadata stream which temporally corresponds to the audio data stream, the audio data stream including an audio data packet and partial identification data, the partial identification data equivocally describing the audio data packet, the audio metadata stream including an identification code, which is able to be determined using the partial identification data and which allows an unequivocal description of the audio data packet;
• buffer-storing the audio data stream and outputting the audio data packet of the buffer-stored audio data stream, the audio metadata stream no longer temporally corresponding to the audio data stream when the audio data packet is output;
• reading in a recording signal when a buffer-stored audio data packet to be selected is output, and storing the partial identification data of the selected buffer-stored audio data packet;
• and
• analyzing at least a portion of the currently received audio metadata stream to determine the identification code for the audio data packet if the stored partial identification data match the data from the audio metadata stream.
