PURPOSE: A video display device easily setting channels and external input is provided to call a watched channel and setup data set in the channel by a simple key operation, and automatically reset video and audio by the setup data, thereby rewatching the watched channel without setting the channel on an OSD(On Screen Display) menu. CONSTITUTION: A tuner(110) selects broadcasting signals. An external signal input unit(120) receives external signals. A signal processor(200) processes the broadcasting signals or the external signals selected by the tuner or the external signal input unit for restoring video and audio through a screen(410) and a speaker(420). A control unit(300) sequentially stores setup data for setting up environments of the tuner, the external signal input unit, and the signal processor according to an external control signal. The control unit sets up the environments of the tuner, the external signal input unit, and the signal processor with previous state or next state data by a standard of any one of the setup data. |
