Abstract
A technique for recording information received by a satellite digital audio radio (SDAR) receiver for playback encrypts content of a received SDAR channel using a local key that is unique to the SDAR receiver. The encrypted content is then stored for playback. When selected for playback, the stored encrypted content is decrypted with the local key and provided to the user.
Claims27
A method for recording information received by a satellite digital audio radio (SDAR) receiver for playback, comprising the steps of:
- receiving an SDAR channel;
- encrypting content of the SDAR channel using a local key that is unique to the SDAR receiver;
- storing the encrypted content from the SDAR channel;
- decrypting the stored encrypted content with the local key;
- and
- selectively providing the decrypted content to the user.
A method for recording information received by a satellite digital audio radio (SDAR) receiver for playback, comprising the steps of:
- receiving a first and second SDAR channel;
- providing content of the first SDAR channel to a user;
- encrypting content of the second SDAR channel using a local key that is unique to the SDAR receiver;
- storing the encrypted content from the second SDAR channel;
- decrypting the stored encrypted content from the second SDAR channel with the local key;
- and
- providing the decrypted content from the second SDAR channel to the user.
A method for recording information digital content for playback, comprising the steps of:
- providing encrypted digital content to a receiver;
- storing the encrypted digital content;
- decrypting the stored encrypted digital content using a local key that is unique to the receiver;
- and
- providing the decrypted digital content to the user.
A system for recording information received by a satellite digital audio radio (SDAR) receiver for playback, comprising the steps of:
- an SDAR receiver for receiving an SDAR channel;
- a processor coupled to the SDAR receiver;
- and
- a memory subsystem coupled to the processor, the memory subsystem storing code that when executed by the processor causes the processor to perform the steps of:
- encrypting content of the SDAR channel using a local key that is unique to the SDAR receiver;
- storing the encrypted content from the SDAR channel;
- decrypting the stored encrypted content from the second SDAR channel with the local key;
- and
- providing the decrypted content from the second SDAR channel to the user.
