Abstract

PURPOSE: An authentication system is provided to connect a media player to a docking station, thereby easily storing media content. CONSTITUTION: If an external terminal and an authentication device are docked, a control unit(170) compares a corresponding pair between stored identification information and an authentication code with a corresponding pair between received identification information and the authentication code. The control unit controls an external terminal docking unit to receive media content from the external terminal in case of an operation mode. In case of the operation mode, an output unit(140) outputs descrambled digital broadcasting content or media content received from the external terminal to an external reproducing device.

Description

Authentication system {Authentication system}

The present invention relates to a mobile media player, and more particularly to a docking station for receiving and storing digital broadcast content operating by docking the mobile media player.

The present invention also relates to a media player that can store broadcast information played by a docking station so that it can be viewed on the go.

As digital content becomes more mobile and the digital convergence trend is accelerating, portable devices commonly encountered in real life are equipped with various functions as well as original functions.

For example, most of today's mobile phones have built-in functions of digital cameras and digital camcorders, and the Portable Multimedia Player (PMP) has the capability to receive and record digital broadcasts.

With such multifunctionalization of portable devices, portable devices have evolved from means for reproducing digital broadcast content to means for producing digital broadcast content, while on the other hand, user interfaces of portable devices are becoming increasingly complex.

Accordingly, it may be difficult for a user who is not familiar with a portable device to play digital broadcast contents stored in the portable device by connecting to a digital TV and / or a set-top box.

On the other hand, even users familiar with mobile devices have limitations such as battery capacity and screen size of the mobile devices, and thus are not a good environment for enjoying digital broadcasting contents using mobile devices.

Moreover, according to the related art, when storing media content received from CATV, satellite antenna, and terrestrial antenna in such a conventional portable device, there is a disadvantage that it must be stored through a complicated process.

This is because the media player must be connected to a set-top box or a digital TV for storing such media content, and the setting is also changed, which is cumbersome to operate.

In addition, in the prior art, it is also possible to connect other media players to the set-top box and / or the digital TV, so there is a problem that security is not maintained. In other words, even if the children are not watching or legitimate users can not restrict the use. It is only necessary to be able to watch digital content from digital TVs and other media players if it is certified.

In addition, the mobile device is easy to be lost due to portability and mobility, and when lost, the content stored in the mobile device becomes vulnerable to security. There is a need to ensure that only legitimate users use the mobile device or protect content stored on the mobile device in case of loss.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the problems according to the prior art, and an object thereof is to provide a media player that easily stores media content and enables playback of stored media content without time and / or location constraints.

It is another object of the present invention to provide a docking station that facilitates the transfer of media content to a media player by simplifying the connection with the media player.

Another object of the present invention is to enhance security by using an authentication technology when connecting a media player to a docking station.

In addition, an object of the present invention is to enhance data security stored in a media player using an authentication technique.

The docking station according to the present invention includes an external terminal docking unit for docking an external terminal to receive external terminal identification information, an authentication device docking unit for docking an authentication device to receive an authentication code, and an external terminal and the authentication device when docked. And a control unit for comparing the corresponding pair of pre-stored identification information and the authentication code with the corresponding pair of the received identification information and the authentication code to switch to an operation mode.

The mobile media player according to the present invention receives the external terminal identification information and the authentication code from the storage unit for storing the identification information, the external terminal and the authentication device, and can be docked with the external terminal and the authentication device. When a docking is performed on an external docking station that outputs an unlocking signal by comparing an authentication code corresponding pair with a corresponding pair of previously stored identification information and an authentication code, a docking connector for outputting the identification information and a lock release signal are received from the docking connector. If so, it includes a control unit for switching from the lock mode to the unlock mode.

In an authentication method of a docking station docked with an external device according to the present invention, the authentication method includes receiving identification information from the external terminal when the external terminal is docked, and an authentication code from the authentication device when the authentication device is docked And receiving, and comparing the received identification information and authentication code correspondence pair with previously stored identification information and authentication code correspondence pair, and switching to an operation mode.

The authentication method of an external terminal according to the present invention is dockable with an external terminal and an authentication device, and receives the external terminal identification information and an authentication code from the docked external terminal and the authentication device, respectively, and receives the identification information and authentication code corresponding pairs. An authentication method of an external terminal docked at a docking station that outputs an unlocking signal by comparing a corresponding pair of stored identification information and an authentication code, wherein the authentication method transmits identification information to the docking station when docked at the docking station. And, upon receiving a lock release signal from the docking station, setting the lock release mode.

According to the present invention, by connecting the media player itself to the docking station, the media content can be easily stored, and the media player can be used to play the stored media content without time or place constraints.

In addition, another effect of the present invention is that the docking station is operated only when it is connected to the media player and the authentication device, so that the use can be restricted. The authentication device may use a conditional access system (CAS) module. Since the CAS module is a necessary device in the case of a pay broadcast model, the CAS module may be used for authentication at no additional cost.

In addition, another effect of the present invention is that only a specific media player corresponding to a specific authentication device can be connected to the docking station, thereby enhancing security and minimizing data leakage when the media player is lost.

4 is a flowchart illustrating an authentication method of a docking station according to an embodiment of the present invention. See FIGS. 1-3.

Referring to FIG. 4, the docking station 100 waits in a standby mode state (S500). In the standby mode, the docking station 100 may be in an idle state to save power.

The docking station 100 determines whether the media player 200 and the authentication device 300 are inserted to receive identification information and an authentication code from each component (S510). If any one is not received, the docking station 100 will remain in the standby mode (S500).

When receiving the identification information and the authentication code, the docking station 100 checks whether the connected media player 200 and the authentication device 300 are a pair of registered devices (S520).
