Mobile ESN for XM Radio Receivers
A system and method for enabling authorized satellite radio access allows users with multiple vehicles to move their radio subscription from one authorized vehicle to another without having to hold two separate subscriptions. In an embodiment of the invention, an XM receiver includes a portable media input, and the XM receiver is programmed to read for the presence of a USB device, SD card, or other peripheral media device containing an authorization code linked to the electronic serial numbers (ESNs) of the XM receivers in the user's vehicles. In addition to having an authorized and subscribed ESN, the XM receiver in each vehicle requires the presence of the portable media device for the receiver to play XM content. The portable media device can also be used to transfer the subscription to a home stereo system, computer, or aftermarket device to allow.
1 . A method of enabling authorized use of a satellite radio system comprising:
receiving a user selection of content to be conveyed to the user;
receiving authorization data from an external user-portable medium;
retrieving an internal subscription data set representing an authorized user of the satellite radio system with respect to the selection of content;
comparing the received authorization data with the internal subscription data set; and
providing the content corresponding to the selection of content to the user if the received authorization data and the internal subscription data set match with respect to at least one preselected criterion and otherwise disallowing access of the user to the content corresponding to the selection of content.
2 . The method according to claim 1 , wherein receiving a user selection of content to be conveyed to the user comprises receiving a user selection via a user interface physically associated with the satellite radio system.
3 . The method according to claim 1 , wherein the external user-portable medium is a contact medium.
4 . The method according to claim 3 , wherein the external user-portable medium is one of a USB device and an SD card.
5 . The method according to claim 1 , wherein the external user-portable medium is a non-contact medium.
6 . The method according to claim 5 , wherein the external user-portable medium is one of an IR device and an RF device.
7 . The method according to claim 1 , wherein the received authorization data includes a first user preference data set and the internal subscription data set includes a second user preference data set.
8 . The method according to claim 7 , further comprising producing a merged user preference set based at least partially ion each of the first user preference data set and the second user preference data set.
9 . A computer-readable medium having thereon computer-executable instructions for enabling authorized use of a satellite radio system, the computer-executable instructions including:
instructions for receiving a user selection of content to be conveyed to the user;
instructions for receiving authorization data from an external user-portable medium;
instructions for retrieving an internal subscription data set representing an authorized user of the satellite radio system with respect to the selection of content;
instructions for comparing the received authorization data with the internal subscription data set; and
instructions for providing the content corresponding to the selection of content to the user if the received authorization data and the internal subscription data set match with respect to at least one preselected criterion and otherwise disallowing access of the user to the content corresponding to the selection of content.
10 . The computer-readable medium according to claim 9 , wherein the instructions for receiving a user selection of content to be conveyed to the user comprise instructions for receiving a user selection via a user interface physically associated with the satellite radio system.
11 . The computer-readable medium according to claim 9 , wherein the external user-portable medium is a contact medium.
12 . The computer-readable medium according to claim 11 , wherein the external user-portable medium is one of a USB device and an SD card.
13 . The computer-readable medium according to claim 9 , wherein the external user-portable medium is a non-contact medium.
14 . The computer-readable medium according to claim 13 , wherein the external user-portable medium is one of an IR device and an RF device.
15 . The computer-readable medium according to claim 9 , wherein the received authorization data includes a first user preference data set and the internal subscription data set includes a second user preference data set.
16 . The computer-readable medium according to claim 15 , further comprising instructions for producing a merged user preference set based at least partially ion each of the first user preference data set and the second user preference data set.
17 . A system for enabling authorized access to satellite radio content, the system comprising:
a satellite radio system including:
a decoding module for decoding encoded satellite radio content;
a computer-readable memory containing a subscription data set; and
a user-portable authorization media containing an authorization data set, wherein the decoding module is adapted to authorize access to the satellite radio content if the subscription data set and the authorization data set identify the same user or permissible related users, and to deny access to the satellite radio content if the subscription data set and the authorization data set do not identify the same user or permissible related users.
18 . The system according to claim 17 , wherein each of the subscription data set and the authorization data set includes a user preference data set.
19 . The system according to claim 17 , wherein the satellite radio system further comprises a user interface for receiving a user selection of satellite radio content and a portable media interface for interfacing the user-portable authorization media to the satellite radio system.
20 . The system according to claim 17 , wherein the user-portable authorization media is one of an SD card, a USB device, an RF card and an IR card.
