METHOD OF TRANSMITTING FM ADDITIONAL BROADCASTING USING FM ADDITIONAL BROADCASTING PROTOCOL

摘要

PURPOSE: A method of transmitting an FM additional broadcasting using an FM additional broadcasting protocol is provided to use a decoding identifier to distinguish frame and packet transmissions, and to use a service ID to distinguish application services, then to use a data group number to group data of the application services, thereby distinguishing an end of the grouped data by using an information ending identifier. CONSTITUTION: A physical layer defines a DARC(Data Radio Channel) modulation system. A data link layer defines a DARC frame structure. A network layer defines a synchronization of a packet, defining a service ID, and defines a structure of a data packet. An application layer represents information classification in accordance with the service ID, and differentiates data formats and information kinds according to the service ID. A significant layer implements an application service.
