Abstract

A method and computer program product for processing a locally-stored, specific media data file portion to generate a first normalized packetized stream. A remotely-sourced, specific media data stream is processed to generate a second normalized packetized stream. At least a portion of the first normalized packetized stream and at least a portion of the second normalized packetized stream are combined, using a packet loss tolerant stitching algorithm, to generate a loss-compensated media data stream.

Claims

1. A method comprising:

processing a locally-stored, specific media data file portion to generate a first normalized packetized stream;

processing a remotely-sourced, specific media data stream to generate a second normalized packetized stream; and

combining, using a packet loss tolerant stitching algorithm, at least a portion of the first normalized packetized stream and at least a portion of the second normalized packetized stream to generate a loss-compensated media data stream.

2. The method of claim 1 further comprising:

rendering the loss-compensated media data stream on a client electronic device.

3. The method of claim 2 wherein the client electronic device is chosen from the group consisting of:

a personal computer;

a laptop computer;

a notebook computer;

a personal media device;

a personal digital assistant;

a data-enabled cellular telephone;

a television;

a cable box;

an internet radio; and

a dedicated network device.

4. The method of claim 1 wherein the locally-stored, specific media data file portion is sampled at a first bit rate and the remotely-sourced, specific media data stream is sampled at a second bit rate, wherein the first bit rate is less than the second bit rate.

5. The method of claim 1 wherein the locally-stored, specific media data file portion is obtained from a remote source using a networking protocol.

6. The method of claim 5 wherein the networking protocol is chosen from the group consisting of:

a Multimedia Messaging Service (MMS) protocol;

a HyperText Transfer Protocol (HTTP);

a FLUTE protocol; and

a Really Simple Syndication (RSS) protocol.

7. The method of claim 1 wherein the remotely-sourced, specific media data stream is obtained from a remote source using a networking protocol.

8. The method of claim 7 wherein the networking protocol is chosen from the group consisting of:

a Real Time Streaming Protocol (RTSP);

a Real-time Transport Protocol (RTP); and

a User Datagram Protocol (UDP).

9. The method of claim 1 wherein processing the locally-stored, specific media data file portion to generate the first normalized packetized stream includes:

parsing the locally-stored, specific media data file portion to generate the first normalized packetized stream.

10. The method of claim 1 wherein processing the remotely-sourced, specific media data stream to generate the second normalized packetized stream includes:

parsing the remotely-sourced, specific media data stream to generate the second normalized packetized stream.

11. The method of claim 1 wherein the locally-stored, specific media data file portion includes metadata.

12. The method of claim 11 wherein the metadata defines a location of the remotely-sourced, specific media data stream.

13. The method of claim 1 wherein the loss-compensated media data stream includes an A/V loss-compensated media data stream.

14. A computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

processing a locally-stored, specific media data file portion to generate a first normalized packetized stream;

processing a remotely-sourced, specific media data stream to generate a second normalized packetized stream; and

combining, using a packet loss tolerant stitching algorithm, at least a portion of the first normalized packetized stream and at least a portion of the second normalized packetized stream to generate a loss-compensated media data stream.

15. The computer program product of claim 14 further comprising instructions for:

rendering the loss-compensated media data stream on a client electronic device.

16. The computer program product of claim 15 wherein the client electronic device is chosen from the group consisting of:

a personal computer;

a laptop computer;

a notebook computer;

a personal media device;

a personal digital assistant;
