Abstract: A cable modem and a data receiving method thereof are provided to control the repetitive reception of the same DSG data and stably receive the DSG data by making DSG(DOCSIS(Data Over Cable Service Interface Specification) Set-top box Gateway) data received through only a designated channel. A downlink channel searcher(100) searches a downlink channel and then receives the whole channel information message through the searched downlink channel. If the message is valid, a downlink channel searcher unit receives an additional broadcasting data information message. A channel information processor(200) receives additional broadcasting data by using the additional broadcasting data information message. A channel manager(400) stores and manages primary data receiving channels which can receive the whole channel information message and additional broadcasting data.

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.
