Apparatus and method for controlling video display device, video display device and multivision system
First Claim
1. A multivision system, comprising:
- a plurality of video display devices; and
a remote controller configured to transmit plural types of control data to the plurality of video display devices,wherein each of the plurality of video display devices includesa storage unit configured to store a video display device specific access code;
a reception unit configured to receive the plural types of control data from the remote controller;
a display unit configured to display data;
a code recognition unit configured to compare received access codes to the access code stored in the storage unit; and
a control unit operatively connected to the code recognition unit and the display unit, the control unit configured to cause the corresponding display unit to display the access code stored in the storage unit when the one of plural types of control data includes control data for canceling an on screen display (OSD) locking function such that each of the plurality of video display devices simultaneously display a corresponding stored access code, and to control the video display device to enter a control mode using an OSD menu if the code recognition unit determines that a subsequently received control data includes an access code that is the same as the access code stored in the storage unit.
