    Digital broadcast has been proved to be the most efficient way to provide messages after heavy disasters where all the communication networks may be damaged. This paper reports several new techniques for Digital Audio Broadcast (DAB) to enhance its ability in emergency warning. A novel bidirectional multimedia communication method between two DAB transmitters is also reported. Government in disaster area can use the local DAB transmitter to communicate in multimedia with the outside. These techniques may find a new application area for the DAB system.
