Method, system, and terminal for using subscription service content

A method for using subscription service content, comprising:

• receiving by a content protection system, a registration request transmitted from a user terminal for using subscription service content, wherein the registration request carries an identifier (ID) of the user terminal, and the user terminal is one of:
• a permanent terminal or a temporary terminal, and wherein the subscription service content is provided by a content distribution system apart from the content protection system;
• determining by the content protection system, whether a number of registered user terminals using the subscription service content registered by the user is greater than a maximum number of user terminals permitted to use the subscription service content according to the ID of the user terminal, wherein the maximum number of the user terminals permitted to use the subscription service content is provided by the user to a content protection system;
• activating the user terminal by the content protection system, such that the user terminal is enabled to receive the subscription service content from the content distribution system, according to the ID of the user terminal, if the number of the registered user terminals using the subscription service content registered by the user is not greater than the maximum number of the user terminals permitted to use the subscription service content;
• and
• delivering, by the content protection system, based on a determination that the number of the registered user terminals using the subscription service content registered by the user is not greater than the maximum number of the user terminals permitted to use the subscription service content, a key for decryption of the subscription service content encrypted by the content protection system to the user terminal;
• requesting, by the user terminal, after receiving the key, the subscription service content from the content distribution system;
• delivering, by the content distribution system, the subscription service content encrypted by the content protection system to the user terminal;
• and
• decrypting, by the user terminal, the service content provided by the content distribution system using the key;
• wherein if the user terminal is the temporary terminal, determining whether a number of registered temporary terminals using the subscription service content registered by the user is greater than a maximum number of temporary terminals permitted to use the subscription service content, and if the number of the registered temporary terminals using the subscription service content registered by the user is greater than the maximum number of the temporary terminals permitted to use the subscription service content, activating, by a content protection system, the temporary terminal replacing an originally registered temporary terminal.

A computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when the computer executable instructions are executed, a computer is enabled to execute a method for using subscription service content, wherein the method comprises:

• receiving a registration request transmitted from a user terminal for using subscription service content, wherein the registration request carries an identifier (ID) of the user terminal, and the user terminal is one of:
• a permanent terminal or a temporary terminal, and wherein the subscription service content is provided by a content distribution system apart from the content protection system;
• determining whether a number of registered user terminals using the subscription service content registered by the user is greater than a maximum number of user terminals permitted to use the subscription service content according to the ID of the user terminal, wherein the maximum number of the user terminals permitted to use the subscription service content is provided by the user to a content protection system;
• activating the user terminal such that the user terminal is enabled to receive the subscription service content from the content distribution system, according to the ID of the user terminal, if the number of the registered user terminals using the subscription service content registered by the user is not greater than the maximum number of the user terminals permitted to use the subscription service content;
• and
• delivering, based on a determination that the number of the registered user terminals using the subscription service content registered by the user is not greater than the maximum number of the user terminals permitted to use the subscription service content, a key for decryption of the subscription service content encrypted by the content protection system to the user terminal;
• requesting, after receiving the key, the subscription service content from the content distribution system;
• delivering the subscription service content encrypted by the content protection system to the user terminal;
• and
• decrypting the service content provided by the content distribution system using the key;
• wherein if the user terminal is the permanent terminal, determining whether a number of registered permanent terminals using the subscription service content registered by the user is greater than a maximum number of permanent terminals permitted to use the subscription service content, and if the number of the registered permanent terminals using the subscription service content registered by the user is greater than the maximum number of the permanent terminals permitted to use the subscription service content, returning a registration failure response message to the permanent terminal.

• delivering the subscription service content encrypted by the content protection system to the user terminal;
• and
• decrypting the service content provided by the content distribution system using the key;
• wherein if the user terminal is the temporary terminal, determining whether a number of registered temporary terminals using the subscription service content registered by the user is greater than a maximum number of temporary terminals permitted to use the subscription service content, and if the number of the registered temporary terminals using the subscription service content registered by the user is greater than the maximum number of the temporary terminals permitted to use the subscription service content, activating, by a content protection system, the temporary terminal replacing an originally registered temporary terminal.
