Abstract

Various embodiments of the invention provide a method for activating one or more secondary decoder devices in a home network. A head-end system activates a primary decoder device and initializes the secondary decoder devices. The primary decoder device activates the initialized secondary decoder device. The secondary decoder device is deactivated upon expiration of a timer value until reactivated by the primary decoder device.

Claims

1. A method for activating one or more secondary decoder devices in a system, comprising:

a head-end system,

a primary decoder device, and

the one or more secondary decoder devices,

the head-end system being communicatively connected to the primary decoder device and to the one or more secondary decoder devices, the method comprising,

the head-end system activating the primary decoder device;

the head-end system initializing the secondary decoder device; and

the primary decoder device activating the initialized secondary decoder device,

wherein the primary decoder device comprises a primary interface configured for communication with a primary smartcard and the secondary decoder device comprises a secondary interface configured for communication with a secondary smartcard, the method further comprising,

receiving in the primary smartcard an activation message from the head-end system, creating in the primary smartcard first activation data using the activation message, providing the first activation data via the primary interface to the primary decoder device, and activating the primary decoder device using the first activation data;

receiving in the secondary smartcard an initialization message from the head-end system, creating in the secondary smartcard initialization data using the initialization message, providing the initialization data via the secondary interface to the secondary decoder device, and initializing the secondary decoder device using the initialization data;

creating in the primary smartcard second activation data and providing the second activation data via the first interface to the primary decoder device;

providing the second activation data from the primary decoder device to the secondary smartcard; and

providing the second activation data from the secondary smartcard via the secondary interface to the secondary decoder device, and activating the secondary decoder device using the second activation data,

and wherein the primary smartcard comprises a first timer, and wherein the method further comprises setting the first timer using a first timer value comprised in the activation message, activating the first timer, and upon expiration of the first timer value providing renewed second activation data from the primary decoder device to the secondary smartcard.

2. The method according to claim 1, wherein the primary interface is further configured for communication with the secondary smartcard, and wherein providing the second activation data from the primary decoder device to the secondary smartcard through the primary interface.

3. The method according to claim 1, wherein the primary decoder device is communicatively connected to the secondary decoder device, and providing the second activation data from the primary decoder device to the secondary smartcard through a communication link between the primary decoder device and the secondary decoder device.

4. The method according to claim 1, wherein the secondary smartcard comprises a second timer, and wherein the method further comprises,

setting the second timer using a second timer value comprised in the initialization message,

activating the second timer, and upon expiration of the second timer value deactivating the secondary decoder device until the renewed second activation data is received in the secondary smartcard.

5. A system comprising:

a head-end system for activating one or more secondary decoder devices in a system comprising the head-end system,

a primary decoder device comprising a primary interface configured for communication with a primary smartcard, and

the one or more secondary decoder devices comprising a secondary interface configured for communication with one or more secondary smartcards, the head-end system being communicatively connected to the primary decoder device and to the one or more secondary decoder devices, the head-end system comprising,

a smartcard management module configured for associating the one or more secondary smartcards with the primary smartcard;

an activation module configured for activating the primary decoder device by providing an activation message to the primary smartcard; and

an initialization module configured for initializing the secondary decoder device by providing an initialization message to the secondary smartcard,

wherein the activation message comprises a first timer value for setting a first timer in the primary smartcard, and wherein the initialization message comprises a second timer value for setting a second timer in the secondary smartcard.

6. A secondary smartcard for use in a system, comprising:

a head-end system,

a primary decoder device comprising a primary interface configured for communication with a primary smartcard, and

one or more secondary decoder devices, the secondary decoder device comprising a secondary interface configured for communication with the secondary smartcard, the secondary smartcard comprising,

a receiver configured for receiving an initialization message from the head-end system, the receiver further configured for receiving activation data from the primary smartcard via the intermediary of the primary decoder device;

a processor configured for creating initialization data using the initialization message;

a transmitter configured for providing the initialization data via the secondary interface to the secondary decoder device for initializing the secondary decoder device, the transmitter further configured for providing the activation data via the secondary interface to the secondary decoder device for activating the secondary decoder device,

further comprising a timer, and wherein the processor is further configured for setting the timer using a timer value comprised in the initialization message and for activating the timer, and wherein the secondary smartcard is configured for deactivating the secondary decoder device upon expiration of the second timer value until a renewed second activation data is received from the primary smartcard.

7. The secondary smartcard according to claim 6, wherein the receiver is configured for receiving the activation data from the primary smartcard via the intermediary of the primary decoder device through the primary interface.

8. The secondary smartcard according to claim 6, wherein the receiver is configured for receiving the activation data from the primary smartcard via the intermediary of the primary decoder device through a communication link between the primary decoder device and the secondary decoder device and the secondary interface.
