Description

TECHNICAL FIELD [0001] The present invention relates to a system, method, and computer readable recording medium for a TV and a smart phone using an image authentication key,

The present invention relates to a system for interfacing a TV and a smartphone, and more particularly, to a system and method for controlling a TV and a smart phone by using an image authentication key, such as a QR code, A method and a computer-readable recording medium of a smartphone.

Recently, display devices of various sizes and types are being released due to the desire of various consumers. In addition, with the popularization of smart phones, various hand-held personal devices are emerging. For example, devices having display means of various sizes such as a smart phone, a pad type terminal, a 7 inch tablet PC, and a 10 inch tablet PC are being released.

On the other hand, apart from the function of displaying only the received airwave or cable broadcasting signal, the interactive function with the user and various additional services using the Internet are provided on the TV.

In addition, a device called a set top box (STB) is additionally required not only for TV but also for receiving digital broadcasting. The term "set-top box" refers to a device that is connected to a TV, receives signals from the outside, appropriately converts the signals, and displays the contents on a TV. A set-top box is a home communication terminal required to use a next-generation interactive multimedia communication service (video on demand (VOD), home shopping, network game, etc.) Also called a subscriber signal converter. It is connected to a network such as an interactive TV, a telephone, or a company's video transmission service (for example, a video dial tone provided by a US regional telephone company).

The set-top box communicates with a video server installed in a telephone company or a general cable broadcasting (CATV) station, and has a function of receiving and converting video signals with basic functions. In addition, various standards such as those having a telephone interface and a connection interface with a personal computer (PC) so that a data communication service such as a telephone and a PC communication can be used at the same time are being examined. As a result, telecom, computer and consumer electronics manufacturers are competing for set-top box commercialization and sales in order to prevail in the interactive TV market.

The set-top box does not necessarily have a built-in tuner. An external signal may include an Ethernet cable, a satellite reception or terrestrial reception antenna, a coaxial cable, a telephone line, an analog Very High Frequency (VHF) UHF (Ultra High Frequency) antenna. The contents that can be obtained through this can be video, voice, internet web page, game, and the like.

As described above, the TV can provide not only broadcast information but also various information services through a set-top box interfaced with the Internet, and it is possible to select and control services through bidirectional communication with a user. In order to facilitate the inputting of a user's selection signal, there is a need for various functions of a remote controller to be expanded and a need for a convenient interface is required.

In addition, the TV having the function of the set-top box can be connected to the Internet as well as watching terrestrial broadcasts, and can perform computer functions such as video-on-demand (VoD), game, video call, and application utilization. On the other hand, considering the fact that the above-described functions can be utilized by connecting the above-described set-top box to a general TV, and the replacement period of the TV is long, the TV and the set-top box market coexist.

Accordingly, as a method for utilizing a computer function using a TV incorporating the functions of the set-top box described above, a smart phone is effectively registered on a TV and interworked with each other, thereby controlling a TV by a registered smart phone, There is a need for a method capable of executing the authentication method for the client terminal itself and the authentication method for the client terminal itself as disclosed in Korean Patent Registration No. 10-1025807 entitled " Authentication method and authentication server (Park Sang- A method for registering and authenticating a separate user terminal (e.g., a smart phone) with a client terminal (e.g., a TV) has not been disclosed at all.
