A method of recording using a timer recording function in a display device is disclosed. More specifically, the display device receives an input data which is a user inputted instruction information for executing a timer recording function. Thereafter, the display device stores the instruction information which includes an instruction for a display recording device to begin and end recording a broadcast program of a certain designated channel at a specified time period in the future. Then, the device determines whether at least two display recording devices are connected to the display device and selects the display recording device for recording the broadcast program. Lastly, the display device transmits control data to the selected display recording device.
