Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and an apparatus for expanding a television screen using an external projector,

The present invention relates to an apparatus and method for extending a screen of a television using an external projector.

A method for projecting light to the rear of an existing television receiver is disclosed in International Patent Publication No. WO2004006570-A1 (published January 15, 2004) and a subsequent patent for improving the same, and a light emitting diode (LED) It is possible to display abstract atmosphere by light by placing light on rear wall and projecting light on inner wall. However, it does not represent concrete visual information with high resolution.

A method of projecting specific visual information having a high resolution outside the main screen output device has been applied to a meeting environment or a working environment equipped with a computer rather than a television use environment. A study using a projector for screen enlargement in a manner similar to the present invention is as follows.

(Graphic User Interface) with the concept of spatial interaction - Focusing on the office environment for group meetings (Cho, Hyeon-Yeon, Lee, Woo-hoon, A method of displaying additional time information through a projector at the periphery of a screen of a screen in a conference room environment is proposed. This method allows for borderless manipulation between the screen and the area projected around the screen.

Augmented surfaces: a spatially continuous workspace for hybrid computing environments (Jun Rekimoto, Masanori Saitoh, Proceedings of the SIGCHI conference on Human factors in computing systems '99, pp. 378-385) The projector is installed on the ceiling and the visual information is projected on the conference table. The projected visual information elements can be interacted with each other and visualized by the projector again so that they can be understood more intuitively.

Bonfire: A Nomadic System for Hybrid Laptop-Tabletop Interaction (Shaun K. Kane, Daniel Avrahami, Jacob O. Wobbrock, Beverly Harrison, Adam D. Rea, Matthai Philipose and Anthony LaMarca. 129-138) utilizes a small projector in a laptop computer environment to display additional visual information on a desk, such as a menu. The user can operate the projected visual information element with his bare hands.

The present invention aims at extending the screen of the television receiver to the peripheral wall surface as described. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a system and method for expanding a television screen using an external projector.

It is an object of the present invention to provide a user interface and time information on an extension line of a television receiver screen by utilizing a projector in a television viewing situation rather than a computer. As the screen area of the television receiver is expanded to the wall surface, the user interface (UI) of the television is intended to be expressed in two screen areas without boundaries.

An expansion device for a television screen, comprising: a remote input device for controlling display of additional information other than a broadcast screen and a broadcast, as a signal input device; Information processing means for receiving a signal from the remote input device and converting it into time information and processing it; And a screen output unit for displaying additional information other than the broadcast screen and the broadcast through the signal converted into the time information.

In one aspect, the remote input device may be an input device including a button-based remote control or a two-dimensional pointing device, and the remote input device may include a character input and input of coordinate values of a pointing cursor.

In another aspect, the information processing means receives and controls the broadcast signal and the input signal of the remote input device, and the Internet can be utilized through the Internet line, and the function of the television can be controlled and transmitted to the screen output unit.

In another aspect, the screen output unit includes a television receiver for displaying a broadcast screen and a projector for displaying additional information other than broadcast, and the television receiver and the projector can be controlled and displayed according to a command received from the remote input apparatus.

In another aspect, the projector is provided at a peripheral portion or a front portion of the television receiver, and can display additional information other than broadcasting by projecting a screen on the wall of the peripheral portion of the television receiver.

In another aspect, the time information processed by the information processing means is composed of a function menu, a pointing cursor, and a widget, and the projector can project the time information transmitted from the information processing means onto a wall surface around the television receiver.

In another aspect, the time information processed by the information processing means is composed of a broadcast screen, a function screen provided by the television, and a pointing cursor transmitted from the remote input device. The television receiver receives the time information transmitted from the information processing means It can be displayed on the screen of the television.

A method for expanding a television screen, the method comprising the steps of: instructing a remote input device to display a broadcast screen and additional information other than broadcasting; The information processing means receiving the signal from the remote input device and converting it into time information and processing it; And displaying additional information other than the broadcasting screen and broadcasting on the screen output unit through the signal converted into the time information.

It is possible to provide a method of constructing an extension scheme and a system of a television screen using an external projector through embodiments of the present invention.

Through the embodiment of the present invention, the projector can be used for a television viewing situation rather than a computer, and a user interface and time information can be provided on an extension line of the television receiver screen.

Further, as the screen area of the television receiver is extended to the wall surface, the user interface of the television can be expressed without bounding the two screen areas.
