Description

Display device, and access point connection method of a display device}

The present invention relates to a display apparatus and an access point connection method of the display apparatus, and more particularly, to a display apparatus and an access point access method of the display apparatus for connecting to the wireless network of the access point.

The display apparatus is, for example, a device having a function of receiving and processing a broadcast image that a user can watch. For example, the display device displays a broadcast selected by a user on a display among broadcast signals transmitted from a broadcasting station. Currently, broadcasting is shifting from analog broadcasting to digital broadcasting worldwide.

Digital broadcasting refers to broadcasting for transmitting digital video and audio signals. Digital broadcasting is more resistant to external noise than analog broadcasting, so it has less data loss, is advantageous for error correction, has a higher resolution, and provides a clearer picture. In addition, unlike analog broadcasting, digital broadcasting is capable of bidirectional services.

In addition, in order to use the digital broadcast, the multimedia device has been improved in performance and multifunctionality compared to the existing multimedia device, and there are various services available in the multimedia device such as Internet service, VOD (Video On Demand), and electronic album service. It was mad.

In order for a display device to provide Internet service, it must be connected to a wired or wireless network. In particular, in order to be connected to a wireless network, the display device must be connected to an access point. Conventional access point access methods use access points such as WEP (Wired Equivalent Privacy), WPA / WPA2 (Wi-Fi Protected Access / Wi-Fi Protected Access2), and WPS (Wi-Fi Protected Setup) to enhance security. Encrypt it.

WEP is a challenge / response security. When a terminal performs an access challenge after searching for an access point according to this method, the access point transmits clear text. The terminal encrypts the clear text with a previously distributed security key and transmits it to the access point to authenticate security credentials and establish a connection.

WPA / WPA2 is a security method that improves the security vulnerabilities of WEP. Its main function is to prevent per-packet key mixing and packet forgery and forgery attacks. User authentication, access control, authorization verification, data confidentiality and integrity are supported.

WPS addresses the challenge of establishing the initial connection to the strong security features of WPA. Each device with WPS has a physical / virtual button and can establish connections at the click of a button between devices.

According to the conventional access point connection method, in order to connect the terminal to the access point, the user must directly enter the password of the access point into the terminal or press a button of the terminal. Therefore, in order to connect to the access point of the display apparatus using a conventional access point connection, the user must directly enter the password of the access point into the display apparatus, and therefore, in the case of a display apparatus that does not have a peripheral device such as a keyboard, the user Will cause great inconvenience. In addition, since the user must press the button of the display device, it causes a great inconvenience to the user.

An object of the present invention is to provide a display device and an access point access method of the display device to enable a user to easily connect the display device to the access point.

In order to achieve the above technical problem, an access point access method of a display apparatus according to the present invention, in a method for accessing an access point having a plurality of identifiers, finds a wireless network service having a first identifier of the access point. Establishing an initial channel with the access point via the found wireless network service, generating a password, and transmitting the generated password to the access point through the established initial channel, and generating the generated password. Using a password as access information, requesting a connection to a wireless network service having a second identifier of the access point. Here, the first identifier and the second identifier may be different. The first identifier may also be a hidden identifier and may be stored in advance.

If a wireless network service with the first identifier is found, the step of setting the initial channel may be executed automatically.

The method of accessing an access point of the display apparatus may further include displaying a message informing of discovery of a wireless network service having the first identifier.

The access point access method of the display device may further include displaying the second identifier and the generated password.

The second identifier may be set to a cipher with the generated cipher.

The requesting the connection may include establishing a normal channel with the access point through a wireless network service having the second identifier of the access point using the generated password as access information. .

The access point may operate in a push button configuration (PBC) mode defined in a protocol of Wi-Fi Protected Setup (WPS).

The plurality of identifiers may be Service Set Identifiers (SSIDs).

In order to achieve the above technical problem, the display device according to the present invention controls the discovery of a wireless network service having a first identifier among a plurality of identifiers of an access point, and through the found wireless network service, access A control unit for controlling a point and initial channel setting, generating a password, and using the generated password as access information, controlling a connection to a wireless network service having a second identifier of the access point, and the generated password It may include a network interface for transmitting to the access point through the set initial channel.

According to the display device and the access point connection method of the display device according to the present invention, the access point is driven by a plurality of identifiers, the display device is connected to the access point with a dedicated identifier, and the password of the public identifier of the access point is automatically set. Afterwards, the user accesses the access point again with the password-set public identifier, so that the user does not have to enter information for the access point or take any further user action on the display device, and the display device does not need to change the wireless setting of the access point. There is no need to make additional settings, and if the private identifier is driven by a hidden identifier, it can prevent malicious wireless network connections.
