Abstract: PURPOSE: An apparatus for separating a digital broadcasting signal from data transmitted through an Internet network and a method therefor are provided to compare IP(Internet Protocol) addresses in hardware without a separate memory and transmit an IP packet at a wire-speed. CONSTITUTION: A transmission medium(100) transmits signals transmitted from a server which provides a digital broadcasting service and an Internet service provider server to a subscriber. A set-top box separates digital broadcasting data and Internet data from data received through the transmission medium, and outputs the separated data to a corresponding device. A television(400) receives and processes the digital broadcasting data outputted from the set-top box. A computer(300) receives and processes the Internet data outputted from the set-top box. The set-top box compares an IP address of a received IP packet with a broadcasting IP address previously designated by a user. If the IP address of the received IP packet is the broadcasting IP address, the set-top box processes the corresponding IP packet as an MPEG-N(Moving Picture Experts Group-N) TS(Transport Stream). If the IP address of the received IP packet is not the broadcasting IP address, the set-top box directly outputs the IP packet to the computer.
