Method and apparatus for providing prepaid music card for deciphering recorded broadcast audio signals
View Patent ↗An apparatus and method are provided for deciphering recorded digital audio signals and using a smart card to pay for deciphering. Encrypted digital audio signals are recorded onto a recording medium, such as a compact disc or the like. When the user desires to listen to the recording, the encrypted recording is inserted into a player/recorder and a prepaid smart card is inserted into a smart card reader connected to the player/recorder. The smart card reader deducts a predetermined value from the card before allowing the player/recorder to decipher the encrypted recording, and record the deciphered audio onto a recording medium for playback.
1. An apparatus for recording and playing a digital signal, comprising:
a receiver for receiving an encrypted digital signal comprising a satellite digital audio radio service (SDARS) signal, the SDARS signal comprising streaming content data and program associated data (PAD) that is synchronized with said streaming content data, said PAD being embedded in said SDARS signal prior to said signal being received and operable to identify a change from a first broadcast segment to a second broadcast segment based on a change in the PAD associated with the streaming content data;
a buffer connected to said receiver for storing at least part of said digital signal as it is being received;
a recorder connected to said receiver for recording onto a first recording medium said encrypted digital signal in response to a user request only if a beginning of said second broadcast segment, identified by a change in the PAD of said stored digital signal, is in said buffer;
a player for playing said first recording medium and connected to a card reader; and
a card having a predetermined value for insertion into said card reader;
wherein when said card is inserted into said card reader, said card reader verifies that said predetermined value is at least a selected minimum value and authorizes said player to decipher said encrypted digital signal from said first recording medium and to record said deciphered signal onto one of said first recording medium and a second recording medium.
2. The apparatus of claim 1 , further comprising:
a key to decipher said encrypted digital signal, said key being stored in one of said card and a memory device in said player.
3. The apparatus of claim 2 , wherein said player is a combination player and recorder, and further comprising:
a second recording medium configured to have said deciphered digital signal recorded thereon.
4. The apparatus of claim 3 , wherein the first recording medium and the second recording medium are the same.
5. The apparatus of claim 1 , wherein said card is a smart card having at least one of a memory device for storing monetary credits, and an integrated circuit for storing information.
6. The apparatus of claim 1 , wherein said card has a memory device for storing said predetermined value, and said card reader is operable to deduct said selected minimum value from said predetermined value stored in said memory device.
7. The apparatus of claim 1 , wherein said card is a prepaid smart card.
8. The apparatus of claim 7 , wherein monetary value can be added and subtracted from said smart card.
9. The apparatus of claim 6 , wherein said card reader is adapted to deduct said selected minimum value from said card only if said beginning of said second broadcast segment was in said buffer.
10. A method for recording and playing digital signals, comprising:
receiving an encrypted digital signal comprising a satellite digital audio radio service (SDARS) signal, the SDARS signal comprising streaming content data and program associated data (PAD) that is synchronized with said streaming content data, said PAD being embedded in said SDARS signal prior to said signal being received and operable to identify a change from a first broadcast segment to a second broadcast segment based on a change in the PAD associated with the streaming content data;
storing said encrypted digital signal in a buffer as it is being received;
determining whether a beginning of said second broadcast segment is in said buffer in response to a user request to record said encrypted digital signal, said determination based on a change in the PAD of said stored digital signal;
recording said encrypted digital signal onto a first recording medium in a recorder and player device only if said beginning of said second broadcast segment is stored in said buffer;
inserting a card having at least a predetermined value into said recorder and player device;
determining that said predetermined value corresponds to at least a selected minimum value; and
deciphering said encrypted digital signal and recording said deciphered signal onto one of said first recording medium and a second recording medium if said card has said selected minimum value.
11. The method of claim 10 , further comprising the step of recording said deciphered signal onto at least one of said first recording medium and a second recording medium.
12. The method of claim 10 , wherein said card has a memory device for storing said predetermined value, and further comprising the step of deducting said selected minimum value from said memory device.
13. The method of claim 10 , further comprising the step of determining whether to deduct value from said card based on whether said beginning of said second broadcast segment was in said buffer.
14. A method for recording and playing an encrypted digital signal, comprising:
receiving an encrypted digital signal comprising a satellite digital audio radio service (SDARS) signal, the SDARS signal comprising streaming content data and program associated data (PAD) that is synchronized with said streaming content data, said PAD being embedded in said SDARS signal prior to said signal being received and operable to identify a change from a first broadcast segment to a second broadcast segment;
storing at least part of said encrypted digital signal in a buffer as it is being received;
electing to record said encrypted digital signal onto a first recording medium;
determining whether a beginning of said second broadcast segment is in said buffer based on a change in the PAD of said stored digital signal; and
recording said encrypted digital signal onto said first recording medium only if said beginning of said second broadcast segment is stored in said buffer;
inserting a card provided with a monetary amount into a card reader connected to said recorder and player;
verifying that said monetary amount corresponds to a selected minimum value; and
deciphering said encrypted digital signal and recording said deciphered signal onto said first recording medium only if said card has said selected minimum value.
15. The method of claim 14 , further comprising the step of adding a monetary amount to said card at one of a card vendor location and an automated teller machine.
16. The method of claim 14 , further comprising the step of adding a monetary amount to said card over a computer network connection.
17. The method of claim 14 , further comprising the step of playing said deciphered digital audio broadcast signals.
