Abstract

A method and system for transmitting multimedia content from a server to a client device includes a source multimedia retriever to retrieve source multimedia content data. A transcoded multimedia retriever retrieves transcoded multimedia content data, the transcoded multimedia content data being a transcoded version of the source multimedia content, and the transcoded multimedia content data being time shifted with respect to the source multimedia content data. A data packet formulator formulates a data packet comprising the source multimedia content data and the time shifted transcoded multimedia content data. A data packet transmitter transmits the data packet from the server to the client device.

Claims

1. A method of transmitting multimedia content from a server to a client device, comprising:

retrieving source multimedia content data;

retrieving a transcoded version of said source multimedia content data, said transcoded version of said source multimedia content data being time shifted in advance with respect to said source multimedia content data; and

simultaneously transmitting said source multimedia content data and said transcoded version of said source multimedia content data from said server to said client device;

wherein said transcoded version of said source multimedia content data provides an alternate source, at said client device, of multimedia content when said source multimedia content data becomes unavailable.

2. The method of transmitting multimedia content from a server to a client device according to claim 1, wherein:

said server is a proxy server retrieving said source multimedia content from a multimedia source server.

3. The method of transmitting multimedia content from a server to a client device according to claim 1, further comprising:

transcoding, at said server, said source multimedia content data.

4. The method of transmitting multimedia content from a server to a client device according to claim 1, wherein:

said simultaneous transmission includes reception of a Transport Control Protocol (TCP)/Internet Protocol (IP) data packet.

5. The method of transmitting multimedia content from a server to a client device according to claim 1, wherein:

said client device is a cellular telephone.

6. A system for transmitting multimedia content from a server to a client device, comprising:

a source multimedia retriever to retrieve source multimedia content data;

a transcoded multimedia retriever to retrieve a transcoded version of said source multimedia content data, said transcoded version of said source multimedia content data being time shifted in advance with respect to said source multimedia content data; and

a data packet transmitter to simultaneously transmit said source multimedia content data and said transcoded version of said source multimedia content data from said server to said client device;

wherein said transcoded version of said source multimedia content provides an alternate source, at said client device, of multimedia content to provide an uninterrupted review of multimedia content associated with said source multimedia content and said transcoded version of said source multimedia content.

7. The system for transmitting multimedia content from a server to a client device according to claim 6, further comprising:

a transcode retriever to retrieve said transcoded version of said source multimedia content data from a transcoded multimedia server.

8. The system for transmitting multimedia content from a server to a client device according to claim 6, wherein:

said simultaneous transmission includes reception of a User Datagram Protocol (UDP) data packet.

9. The system for transmitting multimedia content from a server to a client device according to claim 6, wherein:

said client device is a satellite television receiver.

10. The method of transmitting multimedia content from a server to a client device according to claim 6, wherein:

said client device is a satellite radio receiver.

11. A method of receiving multimedia content from a server at a client device, comprising:

simultaneously receiving, from said server, source multimedia content data and a transcoded version of said source multimedia content data, said transcoded version of said source multimedia content data being time shifted in advance with respect to said source multimedia content data; and

buffering, within a data buffer at said client device, said source multimedia content data and said transcoded version of said source multimedia content data;

wherein said transcoded version of said source multimedia content data provides an alternate source, at said client device, of multimedia content when said source multimedia content data becomes unavailable.

12. The method of receiving multimedia content from a server at a client device according to claim 11, further comprising:

storing said source multimedia content data in a first data buffer portion of said data buffer; and

storing said transcoded version of said source multimedia content data in a second data buffer portion of said data buffer.

13. The method of receiving multimedia content from a server at a client device according to claim 11, wherein:

said simultaneous reception includes reception of a Transport Control Protocol (TCP)/Internet Protocol (IP) data packet.

14. The method of receiving multimedia content from a server at a client device according to claim 11, wherein:

said simultaneous reception includes reception of a User Datagram Protocol (UDP) data packet.

15. The method of receiving multimedia content from a server at a client device according to claim 11, wherein:

said client device is a satellite radio receiver.

16. A system for receiving multimedia content from a server at a client device, comprising:

a data packet receiver to simultaneously receive, from said server, source multimedia content data and a transcoded version of said source multimedia content data, said transcoded version of said source multimedia content data being time shifted in advance with respect to said source multimedia content data;

a data buffer to buffer, within said client device, said source multimedia content data and said transcoded version of said source multimedia content data; and

a multimedia streamer to stream said source multimedia content data to a sensory device and stream said transcoded version of said source multimedia content data to said sensory device;

wherein said transcoded version of said source multimedia content data provides an alternate source, at said client device, of multimedia content when said source multimedia content data becomes unavailable.

17. The system for receiving multimedia content from a server at a client device according to claim 16, wherein:

said data buffer is comprised of a first data buffer portion and a second data buffer portion, said first data buffer portion storing said source multimedia content data and said second data buffer portion storing said transcoded version of said source multimedia content data.

18. The system for receiving multimedia content from a server at a client device according to claim 16, wherein:

said simultaneous reception includes reception of a Transport Control Protocol (TCP)/Internet Protocol (IP) data packet.

19. The system for receiving multimedia content from a server at a client device according to claim 16, wherein:

said simultaneous reception includes reception of a User Datagram Protocol (UDP) data packet.

20. The system for receiving multimedia content from a server at a client device according to claim 16, wherein:

said client device is a cellular telephone.
