TECHNICAL FIELD [0001] The present invention relates to a video display device and an operation method thereof.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display apparatus and an operation method thereof, and more particularly, to an image display apparatus and a method of operating the same that recognize a fingerprint of a user and provide a service mode to a recognized user.

In recent years, digital TV services using wired or wireless communication networks have become popular. The digital TV service can provide various services that can not be provided by the existing analog broadcasting service.

For example, in the case of IPTV (Internet Protocol Television) service, which is one kind of digital TV service, it provides a bidirectionality allowing the user to actively select the type of viewing program, viewing time, and the like. The IPTV service may provide various additional services such as Internet search, home shopping, online game, etc. based on the bidirectionality.

On the other hand, the TV has a setting mode in which a general user can make general settings related to the use of the TV, and a service mode in which a user who gives a schedule authority in the TV manufacturer can make settings related to the operation of the TV. This service mode is also referred to as CS (Customer Service) mode because it is used for after-sales service provided by the TV manufacturer after the product is sold. Thus, in service mode operation, the user can check the operation history, error history, and the like related to the operation of the TV, and can test and adjust related to power, signal, and output. Therefore, since the TV may not operate normally according to the setting of the service mode, only a user having a certain authority in the TV manufacturer is allowed to use the service mode. Thus, for example, a method is used in which only a user who is authorized for the service mode enters the service mode only by using a service remote controller for outputting a signal capable of entering the service mode.

However, the service mode entering method using the service remote control has a problem in that a user who is not authorized to the service mode can use the service remote control, which limits the access to the service mode.

Therefore, there is a need for a method that can restrict the limited user to enter the service mode of the TV.

An object of the present invention is to provide a video display device in which a video display device recognizes a fingerprint of a user and provides a restricted service mode to an authorized user.

A method of operating an image display device according to an embodiment of the present invention includes the steps of acquiring fingerprint information of a fingerprint of a user and transmitting the acquired fingerprint information to a server authenticating whether the user has a right to use the service mode Receiving a service mode authentication signal for a user's right to use the service mode corresponding to the obtained fingerprint information from the server; .

The image display device according to the embodiment of the present invention acquires the fingerprint information of the communication unit and the fingerprint of the user and transmits the fingerprint information acquired through the communication unit to the server authenticating whether the user has the use right for the service mode Receives a service mode authentication signal for a usage right for the service mode of the user corresponding to the obtained fingerprint information from the server, and controls to operate in the service mode based on the received service mode authentication signal And a control unit.

According to various embodiments of the present invention, the present invention can enhance security for use of service modes that require limited use and security.

In addition, the present invention can effectively manage usage and operation history for a service mode that requires limited use and security.
