Video display appliance having function of varying screen ratio and control method thereof
First Claim
1. A video display appliance having a function of varying a screen ratio of twin pictures when a main picture and a sub-picture are simultaneously displayed, the video display appliance comprising:
- a channel selection unit for selecting a channel which transmits data displayed on a main picture region and a sub-picture region;
a video processing unit for processing the data transmitted from the channel tuned by the channel selection unit as a signal to be displayed on the main picture region or the sub-picture region;
a position detecting unit, disposed at a center of the video display appliance, for detecting a position of a remote controller;
a control unit for outputting a control signal to vary the screen ratio of the main picture to the sub-picture in response to position information of the remote controller inputted from the position detecting unit; and
a scaler for outputting video signals outputted corresponding to the main picture and the sub-picture from the video processing unit according to the varied screen ratio, in response to the control signal inputted from the control unit.
