Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to moving images, still images,
The present invention relates to an information display system that receives and displays broadcasts and communications in which text information and the like are transmitted, and in particular, a plurality of displays that can display or present information in a form that allows a user to easily view information according to the type of information. And an information display system having the same.

[0002]

2. Description of the Related Art With the development of broadcasting and communication, much information such as moving images, still images, and text information has been transmitted to homes. Along with this, the development of the receiver side is also progressing, and the large display like the screen of a television receiver has the ability to display not only images but also character information, and the television with a small display like a personal computer Video etc. can be displayed.

[0003]

However, when character information is displayed on a display, such as a television screen, which is installed at a distance from the user, it is difficult to recognize small characters due to problems such as viewing distance. , It is necessary to increase the character size to some extent. Therefore, the amount of character information that can be displayed cannot be made too large. In addition, television and the like are often viewed by a plurality of people.For example, when a moving image is viewed by a plurality of people, a certain part of the moving image or a moving image is obtained in order for a certain user to obtain text information. Displaying character information in a newly created area by reducing the display size of the image impedes viewing by other users who have watched the moving image. In the case of a personal computer display with a short viewing distance, relatively fine character information can be recognized when displaying character information. However, even if a video such as a moving image is displayed, the screen size is small, so that it is poor in power and realism. . Also, in the case of television broadcasts, etc., the content may be viewed by multiple people, but a PC installed in a place that can be reached by hand, such as a desk, is usually viewed by one person. It is difficult for other users to watch at the same time.

[0004] The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to select a display to be displayed according to the type of information to be displayed.
An object of the present invention is to provide a display system capable of displaying information in an easily viewable manner. Another object of the present invention is to provide an information display system in which a plurality of users watch at the same time,
An object of the present invention is to provide an information display system that can obtain other information without hindering viewing of other users.
