Abstract: Provided are a tuning method according to a variable key input length and a broadcast receiving apparatus using the tuning method. The tuning method includes: if it is determined that an input length of one of at least one or more key inputs is more than or equal to a predetermined time, tuning to a first type broadcast; and if it is determined that the input length is less than the predetermined time, tuning to a second type broadcast different from the first type broadcast. Thus, different types of broadcasts can be tuned according to a length of a key input performed by a user. As a result, a digital broadcast channel can be directly input using only a number key.

Abstract: A method for changing a channel by dividing channels into 3D channels and non-3D channels includes receiving a command to change a currently broadcast channel, and if the currently broadcast channel is one of the 3D broadcast channels, changing a screen to another of the 3D broadcast channels in accordance with the command, and if the currently broadcast channel is one of the 2D broadcast channels, changing the screen to another of the 2D broadcast channels in accordance with the command.

Abstract: Disclosed are a video reproducing apparatus, a remote controller for controlling the apparatus, and a method for converting channels of the apparatus that can achieve a fast and easy channel selection through a plural-channel switchover. The video reproducing apparatus includes a key input unit, having a plurality of function keys, including a channel increase key and a channel decrease key, which apply request signals corresponding to the function keys, a channel converting unit, which converts a present channel to a desired channel number, and a control unit, which controls the channel converting unit so as to convert the present channel according to a specified separation of channel switchover if a plural-channel switchover request signal for converting the channel according to the specified separation of channel switchover is input from the key input unit.

Abstract: An apparatus and a method for displaying out-of-band information without turning on a TV or set-top box in an open cable system. A receiving unit receives an out-of-band signal transmitted from a headend and parses the signal. A storage unit stores the parsed data and a user's display setting. A processing unit loads the user's display setting from the storage unit and processes the data according to the user's display setting. A control unit further processes the processed data and causes the further processed data to be displayed on an auxiliary display or main display, wherein the auxiliary display displays the further processed data in a stand-by mode state.
