Abstract
Disclosed is a method and system for sharing a DRM file between portable terminals. The method includes selecting a DRM file stored in a memory by a transmitting terminal, extracting license information from the DRM file by the transmitting terminal, transmitting the license information to a receiving terminal by the transmitting terminal, checking if the receiving terminal acquires a license by the transmitting terminal, externally receiving the DRM file corresponding to the license by the receiving terminal, and reproducing the DRM file in synchronization with the receiving terminal by the transmitting terminal.
Claims22
A method of sharing a DRM (Digital Rights Management) file between portable terminals, the method comprising:
- transmitting a license information to a receiving terminal by a transmitting terminal;
- checking if the receiving terminal acquires a license by the transmitting terminal;
- externally receiving the DRM file corresponding to the license by the receiving terminal;
- and
- reproducing the DRM file in synchronization with the receiving terminal by the transmitting terminal.
A method of sharing a DRM (Digital Rights Management) file between portable terminals, the method comprising:
- selecting the DRM file by a transmitting terminal;
- requesting a server to transmit a license corresponding to the DRM file to a receiving terminal by the transmitting terminal;
- transmitting the license to the receiving terminal by the server;
- externally receiving the DRM file corresponding to the license by the receiving terminal;
- and
- reproducing the DRM file in synchronization with the receiving terminal by the transmitting terminal after the receiving terminal completes receiving the DRM file.
A system for sharing a DRM (Digital Rights Management) file between portable terminals, the system comprising:
- a transmitting terminal for extracting license information from an already stored DRM file to which DRM technology is applied, externally transmitting the license information, selectively externally transmitting the DRM file, and reproducing the DRM file during a connected call;
- and
- a receiving terminal for externally acquiring a license of the DRM file based on the license information, receiving the DRM files and then reproducing the DRM file in synchronization with the transmitting terminal.
A system for sharing a DRM (Digital Rights Management) file between portable terminals, the system comprising:
- a server for providing at least one of a DRM file and a license defining a reproduction right of the DRM file;
- a transmitting terminal for requesting the server to externally transmit the license corresponding to the DRM file already stored therein, and reproducing the DRM file during a connected call;
- and
- a receiving terminal for receiving the license from the server, receiving a DRM file identical to the DRM file stored in the transmitting terminal, reproducing the DRM file in synchronization with the transmitting terminal during the connected call with the transmitting terminal.
