Abstract: An apparatus and methods for controlling broadcast channel access in a video display are provided. The apparatus includes at least one user input unit configured to preset one or more viewable-channel numbers and turn on/off a broadcast channel access mode of the video display, a memory configured to store the preset viewable channel numbers, a controller configured to output a channel selection control signal for selecting only the stored channel numbers when a broadcast channel access mode is turned on, and a channel selector configured for selecting only a required channel out of currently-received broadcast channels according to the channel selection control signal. The apparatus may also include a second user input unit configured to input a required channel number, and a display unit configured to display a video signal of the selected channel.

Abstract: A hinge structure for a flat visual display device comprising: a fixed plate; pivotal plates; a rotation shaft inserted into vertical planes of the fixed and pivotal plates; rotation shaft-fixing ends in both ends of the rotation shaft for allowing the pivotal plates fitted around the ends of the rotation shaft to rotate together with the rotation shaft; a braking unit securely settled in the fixed plate and having a braking member for surrounding the outer circumference of the rotation shaft to generate braking force in the rotation shaft; stoppers folded from the fixed plate; stopper guides each having a guide groove in the outer circumference into which each of the stoppers is inserted and for being fitted around each of the rotation shaft-fixing ends; and a leaf spring inserted into a tightening face between both ends of the braking member.
