wherein the satellite broadcast signal is transmitted by a broadcast headend, wherein the terrestrial IP-based communication signal is transmitted by a content delivery server, and wherein the broadcast headend and the content delivery server are operated by different service providers.

2. A method as defined in claim 1 , wherein the program is at least one of a video program or an audio program.

3. A method as defined in claim 1 , wherein receiving the second plurality of packets via the terrestrial IP based communication signal uses at least one of a file transfer protocol (FTP) or an hypertext transfer protocol (HTTP).

4. A method as defined in claim 1 , wherein a same packet format is used for the first and the second plurality of packets.

5. A method as defined in claim 1 , wherein the first and the second plurality of packets comprise an entirety of the program.

6. A method as defined in claim 1 , further comprising:

storing the spliced beginning and end portions in a file.

7. A method as defined in claim 1 , further comprising:

sending a request to the content delivery server for a third portion of the program, in response to a non-user initiated interruption of the reception of the second plurality of packets representing the end portion of the program;

receiving a third plurality of data packets representing the third portion of the program from the content delivery server and via the terrestrial IP based communication signal in response to the request, wherein the third portion of the program comprises a portion of the end portion not received via the satellite broadcast signal due to the non-user initiated interruption of the reception of the second plurality of packers; and

splicing the third portion of the program to the received second portion of the program.

8. A method as defined in claim 1 , wherein the broadcast headend consists of other than the content delivery server.

9. A non-transitory article of manufacture storing computer readable instructions that, when executed, cause the computer to:

accept a command to view a program in the user device;

receive a terrestrial Internet protocol (IP) based communication signal from a content delivery server, the terrestrial IP-based communication signal representing a beginning portion of the program, wherein the terrestrial IP-based communication signal is addressed to a particular user device, and wherein the broadcast headend and the content delivery server are operated by different service providers;

play back the received beginning portion of the program while receiving and recording a satellite broadcast signal from a broadcast headend, the broadcast signal representing an end portion of a program;

splice the received end portion of the program to the beginning portion of the program; and

play back the spliced received end portion of the program after playing back the received beginning portion of the program;

wherein the first and second portions of the program are decrypted with at least one of a same encryption key, a same codeword or a same secret.

10. A non-transitory article of manufacture as defined in claim 9 , wherein the beginning portion and the end portion comprise an entirety of the program.

11. A non-transitory article of manufacture as defined in claim 9 , wherein the computer readable instructions, when executed, cause the computer to:

store the spliced beginning and end portions in a file.

12. A non-transitory article of manufacture as defined in claim 9 , wherein the computer readable instructions, when executed, cause the computer to:

detect a non-user initiated interruption of the reception of the second plurality of packets representing the end portion of the program; and

send a request to the content delivery server for a third portion of the program in response to the detected non-user initiated interruption of the reception of the second plurality of packets; and

receive a third plurality of data packets representing the third portion of the program from the content delivery server and via the terrestrial IP based communication signal in response to the request, wherein the third portion of the program comprises a portion of the end portion not received via the satellite broadcast signal due to the non-user initiated interruption of the second plurality of packets; and

splice the third portion of the program to the received second portion of the program.

13. A non-transitory article of manufacture as defined in claim 9 , wherein the broadcast headend consists of other than the content delivery server.

14. An apparatus comprising:

a means for accepting a command to view a program;

a first interface to receive a terrestrial Internet protocol (IP) based communication signal from a content delivery server, the terrestrial IP-based signal comprising a beginning portion of the program and containing an address assigned to the first interface;

a second interface to receive a satellite broadcast signal from a broadcast headend, operated by a different service provider than content delivery server, the satellite broadcast signal representing an end portion of the program;

a display module for playing back the received beginning portion of the program while receiving and recording the satellite broadcast signal from the broadcast headend and for splicing the received end portion of the program to the received beginning portion of the program;

a decryptor to decrypt the beginning portion and the end portion of the program before playing back the beginning and end portions based on at least one of a same encryption key, a same codeword, or a same secret; and

a storage device to store a file containing the spliced received beginning portion of the program and end portion of the program.

15. An apparatus as defined in claim 14 , wherein an ending part of the beginning portion is spliced to a beginning part of the first portion.

16. An apparatus as defined in claim 14 , wherein the first interface, the second interface and the storage device are implemented in the same housing.

17. An apparatus as defined in claim 14 , wherein the storage device comprises a hard disk drive.

18. An apparatus as defined in claim 14 , wherein:
