Abstract

A system may time-shift the distribution high-definition (HD) audio. The system can obtain an audio stream from a specified audio source, transcode the audio stream into an HD audio stream, and store the HD audio stream in a memory. The system may later forward the stored HD audio stream to a destination device, which can be a communication device linked to the system through a local telephone network or a remote communication device. The system can also store HD audio when a local communication device receives an incoming call request that interrupts a current HD audio distribution process. The system may resume distribution of the HD audio after processing the incoming call request from a point when the distribution was interrupted.

Claims

1. A device comprising:

a memory;

a communication interface; and

a processor connected with the memory and the communication interface, the processor configured to process time-shift logic, the time-shift logic configured to;

receive a record indication from a communication device, the record indication specifying an audio selection, and in response;

tune the communication interface to obtain initial audio data according to the audio selection;

transcode the initial audio data into High Definition (HD) Voice data; and

store the HD Voice data in the memory; and

receive a forward indication from the communication device, and in response;

determine a destination device; and

transmit the HD Voice data stored in the memory to the destination device through the communication interface.

2. The device of claim 1, where the destination device comprises the communication device.

3. The device of claim 1, where the destination device comprises a remote communication device.

4. The device of claim 3, where the time-shift logic is configured to transmit the HD Voice data to the remote communication device by establishing a call connection with the remote communication device.

5. The device of claim 1, where the time-shift logic is further configured to:

obtain a recorded audio preamble message from the communication device; and

transmit the recorded audio preamble message to the destination device along with the HD Voice data.

6. The device of claim 1, where the time-shift logic is configured to determine the destination device by obtaining identifying information associated with the destination device.

7. The device of claim 6, where the identifying information associated with the destination device comprises a phone number.

8. A device comprising:

a memory;

a communication interface; and

a processor connected with the memory and the communication interface, the processor configured to process time-shift logic, the time-shift logic configured to;

distribute High Definition (HD) Voice data to a communication device;

identify an incoming call request directed to the communication device while distributing the HD Voice data, and in response;

store the HD Voice data in the memory instead of distributing the HD Voice data; and

process the incoming call request.

9. The device of claim 8, where the time-shift logic is configured to process the incoming call request by sending a call alert to the communication device.

10. The device of claim 8, where the time-shift logic is configured to process the incoming call request by establishing a call connection with the communication device and a call device that sent the incoming call request.

11. The device of claim 8, where the time-shift logic is further configured to:

identify a call termination indication; and

in response;

resume distributing the HD Voice data by sending the HD Voice data stored in the memory to the communication device.

12. The device of claim 11, where the time-shift logic is configured to resume distributing the HD Voice data from a point when the incoming call request was identified.

13. The device of claim 11, where the time-shift logic is further configured to continue storing the HD Voice data while resuming distribution of the HD Voice data.

14. The device of claim 11, where the call termination indication comprises an on-hook signal from a calling device that sent the incoming call request.

15. A device comprising:

communication interface circuitry;

time-shift logic circuitry configured to receive a service request indication from a first communication device, the service request indication specifying an audio selection;

the time-shift logic circuitry further configured to tune the communication interface circuitry to obtain initial audio data according to the audio selection specified in the service request indication;

the time-shift logic circuitry further configured, in response to receipt of a record request, to initiate a High Definition (HD) storage process comprising use of transcoder logic circuitry and recorder logic circuitry;

the transcoder logic circuitry configured to transcode the initial audio data received by the communication interface circuitry into HD Audio data; and

the recorder logic circuitry configured to record the HD Audio data in a memory for subsequent distribution.

16. The device of claim 15 wherein the service request indication further specifies an identifier indicative of a second communication device, the time-shift logic circuitry is further configured, in response to the service request identifier, to connect with the second communication device associated with the identifier and initiate distribution of the HD Audio data stored in the memory to the second communication device.

17. The device of claim 15 wherein the time-shift logic circuitry is configured to include telephony logic circuitry configured to receive a voice signal from a second communication device;

and mixing logic circuitry configured to mix the HD Audio data stored in the memory with the voice signal into a mixed signal;

wherein the telephony logic circuitry is further configured to distribute the mixed signal to the first communication device.

18. The device of claim 17 wherein the time-shift logic circuitry is further configured to receive the service request from the second communication device in addition to the first communication device.

19. The device of claim 17 wherein the voice signal is an analog signal and the mixed signal is a VoIP signal.

20. The device of claim 17 wherein the voice signal is a VoIP signal and the mixed signal is an analog signal.
