According to the demand of diversity, real-time and intelligence for transmitting message by DAB, an adaptive packet mode of transport mechanism is put forward to release various text messages (weather warning information, traffic information, etc.) through DAB transmitting system aimed at MOT (Multimedia Object Transfer) protocol. Through the method of adaptive grouping, flexibility and capacity utilization of sub-channels in DAB transmission system are improved greatly. Thus, it is convenient for transfer various early warning information efficiently. The encoding scheme based on adaptive grouping has been achieved through DAB system at present.]]>Dong, L.,2001Fang, L.,200841211213Li-Li, S., Y. Jun-Ping, C. Zhao-Wu and H.
