Transmission of physical layer signaling in a broadcast system

An apparatus comprising:

• a processor;
• and
• a memory having stored therein machine executable instructions, that when executed, cause the apparatus to:
• obtain signaling data for a current data frame of a plurality of data frames, the signaling data for the current data frame comprising a dynamic signaling part, wherein the signaling data contains parameters for decoding a data stream and the dynamic signaling part included in the signaling data for the current data frame is susceptible to change from a dynamic signal part included in signaling data for other frames in the plurality of data frames;
• encode the dynamic signaling part of the signaling data for the current data frame to generate a redundancy data field;
• divide the redundancy data field into a plurality of redundancy data segments;
• insert one redundancy data segment of the plurality of redundancy data segments into the current data frame;
• insert at least one other redundancy data segment of the plurality of redundancy data segments into an extension part located after the dynamic signaling part included in the signaling data in at least one of the other data frames prior to the current data frame;
• and
• output the plurality of data frames.
