Abstract: An additional information processing apparatus and method selectively processes and stores additional information contained in a TV broadcast signal according to specifications set by a user, subdivides information of the type of additional information received in real time, and displays the information on a screen. Additional information contained in a broadcast signal is classified by type before transmission. Only additional information of the type(s) desired by a user is selected and acquired from the received additional information. The type(s) of additional information acquired is (are) displayed on a screen in real time. Accordingly, only the additional information needed by the user is selectively stored in memory and memory can be efficiently used. Since the type(s) of additional information received is (are) displayed on the screen in detail, the user can easily understand the type(s) of additional information being received currently so that the additional information can be effectively used.

Abstract: A modular television for allowing a user to perceive an operation according to a selection of a module and/or a module function, is disclosed. The modular television includes a module rack having at least one module connection slot for mounting at least one module thereon, a main board for transmitting and receiving a multimedia signal to/from the module mounted in the module rack, mutually, and a distinguishable sound generator, when the module mounted on the module rack is selected, for providing a distinguishable acoustic signal corresponding the selection signal of the module.

Abstract: In an apparatus and method for processing a data broadcast signal, additional information contained in a TV broadcast signal can be easily selected and acquired without a time limit by using a still picture. Additional information corresponding to the still picture from additional information transmitted in real time with a moving picture broadcast program is processed, and the additional information is stored, together with still picture information matched with the additional information, so that an object of the additional information included in the moving picture or a picture swiftly changing can be accurately selected from the still picture without a time limit. As a result, additional information corresponding to the selected object is easily acquired. In addition, additional information can be easily searched using still pictures corresponding to additional information stored in a memory.

Abstract: A method of operating an electronic program guide (EPG) is provided, by which a user can effectively move along a programming time axis in the EPG using a remote control device. The method includes receiving a signal indicating a desired future or past programming time to enable a user to move to the desired programming time in an EPG after the user has moved to a desired channel and receiving a program selection signal in an EPG after the user has moved to the desired channel and the desired programming time.

Abstract: There is provided a channel selection method for a digital television, through which a current channel can be easily changed into a channel belonging to the same category as the current channel belongs to. The channel selection method includes (a) generating a channel selection command in response to a user's operation; (b) displaying information about channels, on which programs belonging to the same category as a current channel are broadcasted, on a television screen in response to the channel selection command; (c) selecting a desired channel referring to the information about the channels; and (d) displaying a program which is broadcasted on the selected channel.

Abstract: An apparatus for inputting letters in an electronic device, which can select and input letters in guide screens showing multiple letter groups linked to each other in a tree structure by using only two direction keys and an enter key, and a method thereof are provided. Accordingly, without installing a keyboard in an electronic device, it is possible to simply input letters on a screen using only two direction keys and an enter key in on-screen display letter input menu screens, by dividing letters into sub groups in a tree structure.

Abstract: An apparatus and method for operating an EPG is provided, using a displayed control panel that does not hide program cells including programming information. The apparatus and method for operating an EPG perform the operations of displaying a control panel which controls time information on a display screen that displays an electronic program guide, selecting the time information by highlighting a predetermined button on the displayed control panel, and selecting a channel from among a plurality of channels by highlighting another predetermined button to view programming information for that channel in accordance with the selected. Accordingly, viewers can search for TV programs more conveniently, making time and channel movements more quickly and precisely using a control panel that does not hide program cells that include programming information.
