A method of controlling an operation mode of a TV phone, where the TV phone includes a TV unit that reproduces and outputs a video signal from a selected channel. A display unit interfaces with the TV unit and displays the inputted video signal from the selected channel while in a TV mode. An MRFU receives data of a forward channel transmitted from a base station. An MSP provides a channel selection signal to the TV unit and transmits and receives voice and character signals by controlling the MRFU and generates a display control signal responsive to an incoming character message. An OSD generates a video signal corresponding to the display control signal received at an input of the OSD and provides the generated video signal to the display unit. The method of controlling the operation mode of the TV phone comprises the steps of receiving a character message transmitted from the base station through the forward channel when the video signal generated by the TV unit is displayed on a screen in said display unit during the TV mode. In addition, a video signal of the OSD corresponding to the first line in the received character message is displayed on a portion of the screen of the display unit, while the other portions of the screen display the respective portion of the video signal generated by the TV unit. |
