An apparatus for transmitting a video signal to a remotely installed display apparatus, and a corresponding apparatus for receiving a video signal are provided. The apparatus for transmitting a video signal includes a PCI bridge, a transmitter, and a transceiver-PCI interface. The PCI bridge receives a high-definition (HD) TS or a standard definition (SD) TS, and converts the received HD TS or SD TS to a PCI bus format. The transmitter transmits the HD TS or SD TS, which was converted to the PCI bus format, as a radio signal. The transceiver-PCI interface performs an interface between the transmitter and the PCI bridge. The apparatus for transmitting/receiving a video signal is capable of transmitting/receiving video and audio signals without a wire, thereby allowing easy and convenient installation and management of display devices.
