Abstract:
1. An IP broadcast transmission method which includes a broadcast signal receiving unit, a service information (SI) separating unit, a program distribution server, a channel tuning control server, a program-related information distribution server, an edge router to transmit outputs from the program distribution server, the channel tuning control server and the program-related information distribution server to an internet protocol (IP) network, a service area tuning list generating unit and a control unit to integral operations of a transmitting device and retransmits broadcast signals to the IP network, comprising: acquiring and collecting channel tuning information and program-related information from among broadcast signals of each broadcasting station from which the broadcast signals are distributed, by the control unit, the broadcast signal receiving unit and the SI separating unit; updating and managing the channel tuning information and the program-related information by the control unit and the broadcast signal receiving unit; performing unicast-distributions of the channel tuning information and the program-related information independently from IP multicast-distributions of the broadcast signals by the control unit, the channel tuning control server and the program-related information distribution server; distributing service area tuning lists with the IP multicast-distribution information of the broadcast signals and distribution positions of the channel tuning information and the program-related information of the broadcast signals described therein, by the control unit and the service area tuning list generating unit; and distributing programs with tuning notification notified thereto, as the broadcast signals, by the control unit and the program-related information distribution server.
