Abstract: PURPOSE: A system and a method for transmitting and receiving digital cable broadcasting information are provided to process service information among messages, which are transmitted to a receiver through out-of-band from a head end, more rapidly than other messages. CONSTITUTION: A system for transmitting and receiving digital cable broadcasting information includes a head end module(10) and a reception module. The head end module gives packet identifier numbers limited within a predetermined packet identifier number range to tables on which data is loaded using MPEG transmission technique, and constructs transmission packets to transmit the packets. The reception module receives the transmission packets from the head end module and checks the packet identifier numbers to judge whether or not service information is included in the packets, and decides packet processing according to the judged result.
