Methods and apparatus to provide content on demand in content broadcast systems
View Patent ↗Methods and apparatus to provide content on demand in content broadcast systems are disclosed. An example method comprises receiving a first portion of a program via broadcast signal and receiving a second portion of the program via an Internet protocol (IP) based signal. The example method may further comprise combining the first and the second portions and at least one of store the combined first and second portions in a file or playback the combined first and second portions.
1. A method for playing a media program having a plurality of data packets of a packet format at a user device, the method comprising the steps of:
accepting a command to view the media program in the user device;
receiving and recording the media program from a broadcast headend, the media program received from the broadcast headend having a first set of the plurality of data packets;
determining if the recording of the recording of the media program is interrupted;
if the recording of the media program is interrupted, automatically receiving and recording an interrupted portion of the media program from a content delivery server, the interrupted portion of the media program having a second set of the plurality of data packets, the first set of the plurality of data packets being encrypted with a same encryption key, a same code word, or a same secret as the second set of the plurality of packets;
splicing a received uninterrupted portion of the media program to the interrupted portion of the media program in the user device; and
after splicing the received interrupted portion, playing back the spliced received interrupted portion of the media program after playing back the received uninterrupted portion of the media program;
wherein the first set of the plurality of data packets is received from a broadcast headend via a broadcast signal and the second set of data packets includes an Internet Protocol (IP) header.
2. The method of claim 1 , wherein the second set of data packets is received from a content delivery server operated by a vendor external to a broadcast headend via an IP-based communication signal.
3. The method of claim 2 , further comprising:
receiving an IP address of the IP-based communication signal from the broadcast headend; and
the IP based communication signal is received via the received IP address.
4. The method of claim 3 , wherein the IP address is a multicast address.
5. The method of claim 1 , wherein:
each of the plurality of data packets comprises a respective sequence number, and
splicing the received interrupted portion of the media program to the received uninterrupted portion of the media program in the user device comprises assembling the plurality of data packets according to the respective sequence numbers.
6. The method of claim 1 , further comprising the step of:
storing the spliced interrupted portions of the media program and uninterrupted portions of the media program in a file.
7. The method of claim 1 , wherein the media program comprises a sporting event.
8. A non-transitory article of manufacture storing computer readable instructions that, when executed, cause a user device to play a media program having a plurality of data packets of a packet format at a user device, the computer readable instructions comprising instructions for:
accepting a command to view a media program in the user device;
receiving and recording the media program from a broadcast headend, the media program received from the broadcast headend having a first set of the plurality of data packets;
determining if the recording of the recording of the media program is interrupted;
if the recording of the media program is interrupted, automatically receiving and recording an interrupted portion of the media program from a content delivery server, the interrupted portion of the media program having a second set of the plurality of data packets, the first set of the plurality of data packets being encrypted with a same encryption key, a same code word, or a same secret as the second set of the plurality of packets;
splicing a received uninterrupted portion of the media program to the interrupted portion of the media program in the user device; and
after splicing the received interrupted portion, playing back the spliced received interrupted portion of the media program after playing back the received uninterrupted portion of the media program;
wherein the first set of the plurality of data packets is received from a broadcast headend via a broadcast signal and the second set of data packets includes an Internet Protocol (IP) header.
9. The article of manufacture of claim 8 , wherein the second set of data packets is received from a content delivery server operated by a vendor external to a broadcast headend via an IP-based communication signal.
10. The article of manufacture of claim 9 , wherein the instructions further comprise:
receiving an IP address of the IP-based communication signal from the broadcast headend; and
the IP based communication signal is received via the received IP address.
11. The article of manufacture of claim 10 , wherein the IP address is a multicast address.
12. The article of manufacture of claim 8 , wherein:
each of the plurality of data packets comprises a respective sequence number, and
the instructions for splicing the received interrupted portion of the media program to the received uninterrupted portion of the media program in the user device comprise instructions for assembling the plurality of data packets according to the respective sequence numbers.
13. The article of manufacture of claim 8 , wherein the instructions further comprise instructions for:
storing the spliced interrupted portions of the media program and uninterrupted portions of the media program in a file.
14. The article of manufacture of claim 8 , wherein the media program comprises a sporting event.
