A graphic card embedded with a terrestrial DMB(Digital Multimedia Broadcasting) reception card is provided to enable a user to receive terrestrial DMB in a desktop computer by installing only the graphic card, as the terrestrial DMB reception card is embedded in the graphic card. A terrestrial DMB unit including a terrestrial DMB part capable of receiving the terrestrial DMB is combined with the graphic card as one body. The terrestrial DMB unit includes an antenna for receiving a terrestrial DMB signal broadcasted from a terrestrial base station, and a USB(Universal Serial Bus) port for transmitting an output signal of the terrestrial DMB part to a main board of the desktop computer and receiving power from the main board. The terrestrial DMB part includes a DMB front-end module(231) converting a terrestrial high frequency signal received from the terrestrial base station into a middle frequency signal, a middle frequency processor(235) removing a DC component by receiving the middle frequency signal, and a base band processor(237) demodulating an audio, video, and data signal from the signal output from the middle frequency processor.
