A method and a device for processing a menu of an external device, and a TV receiving device are disclosed. By associating a displaying position of a menu of an external device of a display device with interface position information of an external interface, the present disclosure allows the menu of the external device to be displayed at an insertion position of the TV receiving device (i.e., a position corresponding to the external interface) so that the user can clearly know the using conditions of the external interface. This makes the TV receiving device intuitive and convenient to use.
