System, method and computer readable recording medium for linking television and smart phone using image authentication key

The present invention relates to a system for linking a TV (TV) and a smartphone, and more specifically, a user's smartphone can be registered on the TV using an authentication key in the form of an image such as a QR code (registered trademark). Related to TV-smartphone interlocking systems and methods using image authentication keys and computer-readable recording media.

Recently, various sizes and types of display devices have been released to reflect the needs of various consumers. In addition, with the popularization of smartphones, various hand-held personal devices have appeared. For example, devices equipped with display means of various sizes such as smartphones, pad-type terminals, 7-inch tablet PCs, and 10-inch tablet PCs are on the market.

On the other hand, TVs are also provided with an interactive function with users and various additional services using the Internet, instead of simply displaying the received terrestrial or cable broadcast signal.

Moreover, in order to receive digital broadcasting, not only a TV but also a device called a set top box (STB) is required. The set-top box means a device that is connected to a TV, receives a signal input from the outside, converts it appropriately, and displays the contents on the TV. Set-top boxes are typically home communication terminals needed to use next-generation interactive multimedia communication services (so-called interactive TVs) such as Video on demand (VOD), home shopping, and network games. It has the meaning of a box that can be used by placing it on a TV set, and is also called a "subscriber signal converter". Access networks such as two-way TVs, telephones, and corporate video transmission services (eg, video dial tones provided by US regional telephone companies), and connect to TVs at home.

The set-top box has a video signal reception and conversion function as a basic function in addition to communicating with a video server provided in a telephone company or a general cable broadcasting (CATV) station. In addition, various standards are being studied, such as having a telephone interface and a connection interface with a personal computer (PC) so that data communication services such as telephone and PC communication can be used at the same time. As a result, telecommunications, computer and consumer electronics manufacturers are competing to commercialize and sell set-top boxes in order to preempt the interactive TV market.

On the other hand, the set-top box does not necessarily have to have a built-in tuner, and as a device for giving an external signal to the set-top box, an ethernet cable, a satellite wave receiving antenna or a terrestrial wave receiving antenna, etc. Coaxial cables, telephone lines, analog VHF (Very High Frequency) or UHF (Ultra High Frequency) antennas can be mentioned. Contents that can be received via this include video, audio, Internet web pages, games, and the like.

In this way, TVs can provide not only broadcast information but also various information services via set-top boxes linked to the Internet, and services can be selected and controlled via two-way communication with users. It becomes. In order to facilitate such user selection signal input, it is necessary to expand the functions of the remote controller in various ways, and it is necessary to provide a convenient interface.

In addition, TVs with such set-top box functions are connected to the Internet, not to mention watching terrestrial broadcasts, and can be used as computers for VoD (Video-On-Demand), games, video calls, application utilization, etc. It is possible to have a function. On the other hand, the above-mentioned functions can also be utilized in general TVs via the set-top box connection described above, and considering the fact that the TV replacement cycle is long, the TV and set-top box markets coexist and develop. There is.

Therefore, as one of the methods for utilizing the computer function by using the TV with the built-in set-top box function described above, the registered smartphone is effectively registered in the TV and interlocked with each other. There is a demand for a method for controlling TVs and running various applications in conjunction with each other. However, for example, Patent Document 1 only discloses an authentication method for the client terminal itself, and describes a method for registering and authenticating another user terminal (for example, a smartphone) in the client terminal (for example, TV). Not disclosed at all.
