Abstract

Disclosed are a system and a method for playing back contents based on a smart card, and a smart card applied to the same. A browser of a user terminal using a smart card queries a multimedia source of a user existing within the smart card and the multimedia source is played back in real time through the user terminal. A streaming or downloading playback service is provided to provide the user terminal with the multimedia source in real time.

Claims

a user terminal configured to request, from a smart card, a script file of contents to be played back through an embedded browser, wherein the user terminal is also configured to analyze the script file provided from the smart card and to receive the contents to be played back from the smart card through a communication channel, which is classified according to the contents playback manner; and

a smart card configured to create the script file defining the playback manner of the contents to be played back, wherein the script file is created according to the request of the user terminal to provide the created scripted file to the user terminal, and wherein the smart card is configured to provide the contents to be played back to the user terminal through the classified communication channel, which is preset according to the contents playback manner, wherein playback is in response to the request for provision of the contents by the user terminal based on the scripted file.

2. The system as claimed in claim 1, wherein when receiving the request for the contents to be played back in a streaming playback manner from the user terminal, the smart card extracts the stored contents to be played back and provides the extracted contents in real time through a real-time transport protocol (RTP) communication channel.

3. The system as claimed in claim 1, wherein when receiving the request for the contents to be played back in a downloading playback manner from the user terminal through a hypertext transfer protocol (HTTP) communication channel, the smart card sets a download connection path of the user terminal to a connection address (i.e., to a universal resource locator (URL) of the stored contents to be played back.

4. A user terminal comprising:

a card interface configured to form a communication channel with a mounted smart card and provide a connection path to the smart card;

a browser configured to request, from the smart card, a script file of contents, which are stored in the smart card, to be played back, and configured to analyze the script file provided from the smart card to recognize a playback manner of the contents to be played back; and

a contents player configured to receive the contents to be played back from the smart card through a communication channel, which is classified according to the recognized playback manner, and the contents player is configured to play back the received contents.

5. The user terminal as claimed in claim 4, wherein the browser requests, from the smart card, the script file defining the playback manner of the contents to be played back based on a hypertext transfer protocol (HTTP) connection address (i.e., a universal resource locator (URL)) of the contents to be played back.

6. The user terminal as claimed in claim 4, wherein when the playback manner of the contents to be played back is a streaming playback manner, the contents player receives the contents to be played back in real time through a real-time transport protocol (RTP) communication channel provided by the smart card and the contents player plays back the received contents

7. The user terminal as claimed in claim 4, wherein when the playback manner of the contents to be played back is a downloading playback manner, the contents player connects to a connection address (i.e., URL) of the stored contents to be played back through a HTTP communication channel provided by the smart card and downloads the contents to be played back.

8. A smart card comprising:

a terminal interface configured to form a communication channel with a user interface and provide a connection path to a user terminal; and

a streaming server configured to, when receiving a request for transmission of a script file from the user terminal, create the script file defining a playback manner of the stored contents to be played back and to provide the created script file to the user terminal, and when receiving a request for provision of contents based on the script file from the user terminal, to provide the contents to be played back through a communication channel, which is preset and classified according to the contents playback manner.

9. The smart card as claimed in claim 8, wherein the streaming server includes:

a contents storage configured to store one or more contents whose playback manner is classified based on connection addresses (i.e., universal resource locators (URL));

an interface configured to provide the created script file to the user terminal in response to the request for the script file on the contents of the user terminal, and to receive the request for provision of the contents from the user terminal based on the provided script file and to provide the contents to be played back through a communication channel, which is preset and classified according to the contents playback manner; and

a script creator configured to check the playback manner of the contents stored in the contents storage, and to create the script file defining the playback manner and to provide the created script file to the interface.

10. The smart card as claimed in claim 9, wherein the interface checks storage of the contents to be played back according to a request for the script file on the contents to be played back based on a hypertext transfer protocol (HTTP connection address (i.e., a URL) received from the user terminal through a HTTP communication channel and requests the script creator to create the script file.

11. The smart card as claimed in claim 9, wherein when receiving a request for contents to be played back in a streaming playback manner from the user terminal, the interface extracts the stored contents and provides the extracted contents in real time through a real-time transport protocol (RTP) communication channel.

12. The smart card as claimed in claim 9, wherein when receiving a request for contents to be played back in a downloading playback manner from the user terminal through a HTTP communication channel, the interface sets a download connection path of the user terminal to a connection address (URL) of the stored contents to be played back.

13. A method for playing back contents based on a smart card, the method comprising the steps of:

requesting, by a user terminal from a smart card, a script file of contents to be played back through an embedded browser;

creating, by a smart card, the script file defining a playback manner of the contents to be played back in response to the request for the script file by the user terminal and providing the created script file to the user terminal;

analyzing, by the user terminal, the script file provided by the smart card and checking the contents playback manner;

requesting, by the user terminal, the contents to be played back through a communication channel classified according to the contents playback manner;

providing, by the smart card, the contents to be played back through the classified communication channel preset according to the contents playback manner in response to the request for provision of the contents by the user terminal based on the script file; and

receiving, by the user terminal, the contents to be played back from the smart card and playing back the received contents.

14. The method as claimed in claim 13, wherein in requesting a script file, the user terminal requests a script file of the contents stored in the smart card based on a hypertext transfer protocol (HTTP) connection address (i.e., universal resource locator (URL)).
