Abstract

There is disclosed a media player comprising a playing unit being arranged to play at least one media element, and a processing unit being arranged to identify at least one data element in said media element, to extract said data element from the media element, and to make said data element available to an external NFC device. Furthermore, there is disclosed a corresponding method for playing media, a corresponding computer program, and a corresponding article of manufacture.

Claims

1. A media player comprising:

a playing unit being arranged to play a media element;

a processing unit being arranged to identify at least one data element in said media element, to extract said at least one data element from the media element, and to make said at least one data element available to an external Near Field Communication (NFC) device;

wherein the at least one data element comprises a command that initiates an authentication process between the media player and the external NFC device and wherein the authentication process involves the media player outputting a message on a display of the media player in which a user is prompted to tap the external NFC device on the media player, which enables an NFC channel to be established between the external NFC device and the media player to facilitate the authentication process between the media player and the external NFC device;

wherein said command, when being executed, initiates the authentication process before the media element is played by the playing unit or while the media element is being played by the playing unit; and

wherein the media element is played by the playing unit or continued to be played by the playing unit only after the authentication process between the media player and the external NFC device results in a positive authentication.

2. A media player as claimed in claim 1, wherein the processing unit is arranged to make the at least one data element available by writing said at least one data element to a location of a memory comprised in the media player, said location being allocated to an emulated NFC card comprised in the media player.

3. A media player as claimed in claim 1, wherein the processing unit is arranged to make the at least one data element available by writing said at least one data element to a memory comprised in an NFC tag which is connected to or embedded in the media player.

4. A media player as claimed in claim 1, wherein the processing unit is arranged to make the at least one data element available by providing said at least one data element to an NFC reader/writer which is connected to or embedded in the media player.

5. A media player as claimed in claim 1, wherein the processing unit is arranged to make the at least one data element available while the media element is being played by the playing unit.

6. A media player as claimed in claim 1, wherein the at least one data element comprises user-relevant information relating to the media element and/or at least one reference for obtaining said user-relevant information.

7. A media player as claimed in claim 1, wherein said command comprises an authentication key and a request to verify said authentication key.

8. A media player as claimed in claim 1, wherein said command, when being executed, initiates the retrieval of at least one authentication key stored in the external NFC device.

9. A media player as claimed in claim 1, wherein the media element is at least one of a portion of a video stream, a portion of a video file, a portion of an audio stream, a portion of an audio file, a portion of an internet live stream, a portion of a game.

10. A media system comprising a media player as claimed in claim 1, and an NFC device.

11. A method for playing media at a media player, wherein:

a processing unit of said media player identifies at least one data element in a media element, extracts said at least one data element from the media element, and makes said at least one data element available for reading by an external NFC device, wherein said at least one data element comprises a command that initiates an authentication process between said media player and the external NFC device and wherein the authentication process involves the media player outputting a message on a display of the media player in which a user is prompted to tap the external NFC device on the media player, which enables an NFC channel to be established between the external NFC device and the media player to facilitate the authentication process between the media player and the external NFC device;

wherein said command, when being executed, initiates the authentication process before the media element is played by the playing unit or while the media element is being played by the playing unit;

a playing unit of said media player plays said media element or continues to play said media element only after the authentication process between the media player and the external NFC device results in a positive authentication.

12. A computer program comprising program elements stored on a non-transitory computer readable medium and executable by a playing unit or a processing unit, said program elements comprising instructions which, when being executed by the playing unit or the processing unit, cause said playing unit and said processing unit to carry out or control respective steps of a method as claimed in claim 11.

13. An article of manufacture including a non-transitory computer-readable storage medium having a computer program stored thereon that comprises program elements executable by a playing unit or a processing unit, said program elements comprising instructions which, when being executed by the playing unit or the processing unit, cause said playing unit and said processing unit to carry out or control respective steps of a method as claimed in claim 11.
