Abstract

A method of authenticating communication between a receiver/decoder and a remote server is disclosed. The method involves using an identifier of the receiver/decoder to authenticate the communication, the identifier being based on a smartcard number. Also disclosed is a gateway which is adapted to receive data from a receiver/decoder, which data are not in internet protocol, and to convert said data into internet protocol for transmission to an internet service provider.

Claims

1. A method of authenticating communication between a receiver/decoder and a remote device for providing access to a network, the method comprising:

authenticating the communication using an unique identifier that identifies the receiver/decoder, wherein the unique identifier is based on a subscription for broadcast services of the receiver/decoder;

wherein the receiver/decoder indirectly accesses the network to obtain internet services via a gateway interposed between the receiver/decoder and the remote device, and wherein the unique identifier authenticates the communication with the gateway,

wherein low-level communication between the receiver/decoder and the gateway is performed using a message structure comprising a gateway protocol version a command identifier that identifies a type of the message, wherein the type of the message defines the at least one parameter included in the message, and a data length indicating an overall length of the least one parameter, wherein the at least one parameter identifies the remote device and comprises data to be communicated to the remote device for purposes of obtaining the internet services,

wherein the internet services are associated with a subscription for access to internet services and wherein the broadcast services subscription and the internet services subscription are linked such that the broadcast and internet services subscriptions are managed together, wherein the linked internet and broadcast subscriptions are used to obtain both internet services and broadcast services,

wherein the network is associated with corresponding network protocols, and data output from the receiver/decoder is converted into data compliant with the network protocols by the gateway interposed between the receiver/decoder and the remote device, and

wherein the network comprises a plurality of remote devices, wherein said converted data is communicated by the gateway to one of the plurality of remote devices as specified in said data, wherein a communication channel is established between the receiver/decoder and the one of the plurality of remote devices.

2. The method according to claim 1, wherein the unique identifier is stored on a removable component of the receiver/decoder.

3. The method according to claim 1 wherein the unique identifier is independent of a network login identifier for the receiver/decoder.

4. The method according to claim 1, wherein the unique identifier is based on a number unique to a smartcard for use with the receiver/decoder.

5. The method according to claim 1, wherein the one of the plurality of remote devices is for accessing the internet.

6. The method according to claim 1, wherein the one of the plurality of remote devices is an internet account management system.

7. The method according to claim 6, wherein an internet account for a user is established by the internet account management system using the unique identifier of the receiver/decoder.

8. The method according to claim 7, wherein the unique identifier of the receiver/decoder is compared by the internet account management system with a stored list of identifiers of receiver/decoders which may establish internet accounts.

9. The method according to claim 7, wherein the one of the plurality of remote devices comprises means for sending data to an internet service provider and wherein said method comprises the steps of providing details of the internet account to the internet service provider to establish a bi-directional data pathway between the receiver/decoder and the internet service provider.

10. The method according to claim 1, wherein said unique identifier is accompanied by data identifying a data pathway to be used for communication between the receiver/decoder and one of the plurality of remote devices.

11. The method according to claim 1, wherein a message instructing termination of the communication channel is communicated from the receiver/decoder to the gateway using the non-internet protocol, the gateway in turn communicating a termination command to the specified remote device using the internet protocol.

12. The method according to claim 1, wherein the identification of the receiver/decoder is authenticated by the gateway before the communication channel is established.

13. The method according to claim 1, wherein the at least one parameter is at least one selected from the group consisting of a parameter that contains data received from the one of the plurality of remote devices, and a parameter that identifies an error condition.

14. The method according to claim 1, wherein the one of the plurality of remote devices requires authentication of the receiver/decoder, and wherein the gateway prompts the receiver/decoder for authenticate parameters to authenticate to the one of the plurality of remote devices.

15. The method according to claim 14, wherein the authentication parameters include a smartcard number.

16. The method of claim 14, wherein, upon authentication of the receiver/decoder, a subscriber using the receiver/decoder is permitted access to internet services via a connection account, wherein the connection account is an account used for subscriber log-in.

17. The method of claim 16, wherein the subscriber log-in is performed using a modified signed digit (MSD) number, wherein the MSD number is partially derived from the smartcard number.

18. The method of claim 16, wherein the connection account is linked to at least one directory account, wherein the at least one directory account provides the subscriber with access to internet services.

19. The method of claim 18, wherein the directory account comprises:

an identifier and a password;

at least one electronic mail aliases; and

data related to internet services offered to the subscriber.

20. An apparatus for authenticating communication between a receiver/decoder and a remote device for providing access to a network, the apparatus comprising:

the receiver/decoder comprising an unique identifier that identifies the receiver/decoder and is based on a subscription to broadcast services of the receiver/decoder; and

a gateway interposed between the receiver/decoder and the remote device configured to provide indirect access to the network to the receiver/decoder, wherein communication with the gateway is authenticated using the unique identifier associated with the subscription to broadcast services and wherein access to the network provides a subscriber with internet services,

wherein low-level communication between the receiver/decoder and the gateway is performed using a message structure, and wherein the message structure comprises a gateway protocol version, a command identifier that identifies a type of the message, wherein the type of the message defines at least one parameter included in the message, and a data length indicating an overall length of the at least one parameter, wherein the at least one parameter identifies the remote device and comprises data to be communicated to the remote device for purposes of obtaining the internet services; and

a subscriber management system configured to link the subscription to broadcast services with a subscription associated with the internet services to manage and provide both broadcast services and internet services to the subscriber,

wherein the network is associated with corresponding network protocols, and data output from the receiver/decoder is converted into data compliant with the network protocols by the gateway interposed between the receiver/decoder and the remote device, and

wherein the network comprises a plurality of remote devices, wherein said converted data is communicated by the gateway to one of the plurality of remote devices as specified in said data, wherein a communication channel is established between the receiver/decoder and the one of the plurality of remote devices.

21. The apparatus according to claim 20, wherein said unique identifier is accompanied by data identifying a data pathway to be used for communication between the receiver/decoder and the one of the plurality of remote devices.

22. The apparatus according to claim 20, wherein the at least one parameter is at least one selected from the group consisting of a parameter that contains data received from the one of the plurality of remote devices, and a parameter that identifies an error condition.
