Description

Character information display device {Device for displaying caption information}

The present invention relates to a display device for text information, and more particularly, to a device that can display the size or shape of the sentence information included in the image information corresponding to the user-specified information.

Along with the commercialization of digital broadcasting and data broadcasting, data including text and graphic information as well as existing image information are being transmitted. Such data broadcasting can provide a variety of information to viewers as a new concept of information provision.

Such data broadcasting can provide a wider variety of information to viewers, and can treat information such as audio and video as data, and can compress the amount of data by including a method of reducing the number and combinations of repetitions as in computer data. In addition, there is an advantage that the amount of transmission required to transmit the same content is reduced. This advantage makes it possible to efficiently use the frequency, which is a limited physical resource.

However, there is a problem in that the terminal device has no choice but to display the text information (text) included in such data in the size, shape, or color set at the time of manufacture of the terminal device.

Therefore, even if these characters are displayed, it is inconvenient to be close to the TV to identify them. In addition, in the case of a large TV, the size of a character increases with an increase in an image signal, but there is a problem that character information of a predetermined size or more may cause inconvenience to a viewer.

As described above, the conventional text information display apparatus has many problems as described above in displaying text information included in data broadcasting.

Accordingly, an object of the present invention is to provide a device capable of displaying the size of text information included in a broadcast wave signal in a user-specified size.

Another object of the present invention is to provide an apparatus that enables a viewer to easily recognize text information, subtitles, etc. by reducing or expanding the size of text information included in a broadcast signal.

In addition, another object of the present invention is to provide a device that can display not only the size of the text information, but also the shape, color, attributes, and the like of the text information corresponding to the information specified by the user.

In addition, another object of the present invention can provide a character setting bar that can conveniently set the size, shape, color, attributes, etc. of the character by the operation of the remote control.
