A broadcast signal is received that includes a data identifier that identifies data associated with the broadcast signal. The broadcast signal also includes the data associated with the broadcast signal encoded in the broadcast signal. The data associated with the broadcast signal includes an indicator to ignore the data identifier contained in the broadcast signal. The system decodes the data encoded in the broadcast signal while ignoring the data identifier contained in the broadcast signal. The indicator to ignore the data identifier contained in the broadcast signal may include an associated time period during which the data identifier should be ignored. The data identifier is broadcast in scan line twenty-one of a broadcast image. The data associated with the broadcast signal is encoded in vertical blanking interval lines of a broadcast image.
