Abstract: Disclosed are a method and an apparatus of transmitting packet filtering information. A DSG channel information management server included in a digital cable broadcasting transmission headend combines a packet address and information related to the packet address and generates the combined information to be a single file, the packet address being used for filtering packets received by a cable modem contained in a cable broadcasting receptor, for each data type. The generated file is transmitted from a CMTS to the cable modem through a packet having a designated address mutually agreed upon between the headend and the cable modem, the cable modem obtains information for selectively filtering the received packets, from the received file, and constructs a filter. Data selectively filtered through each constructed filter is transmitted to a corresponding process module included in the cable broadcasting receptor that processes broadcasting program information, conditional access information, and the like.
