Abstract

The disclosed embodiments include a method, apparatus, and computer program product for simplifying the process of creating a video-on-demand system. For example, in one embodiment, a method for creating a video-on-demand (VOD) system is disclosed that includes dynamically capturing segments of an adaptive bit rate (ABR) live stream of the program at time of broadcasting and storing the captured segments of the ABR live stream of the program as a VOD file. In some cases, a particular bit rate of the program can be selected for playback on a client device, based on the type of the client device.

Claims

1. A method, comprising:

receiving a request to record a broadcast video program;

determining when the program is to be broadcast;

dynamically capturing segments of fragmented-type encoding live stream of the program at a time of broadcasting;

storing, in a data storage unit, the captured segments of the fragmented-type encoding live stream of the program;

receiving a request from a client device to view the program;

identifying a type of the client device;

dynamically selecting a particular bit rate of the program for playback based on the type of the client device;

playing back the captured fragmented-type encoding segments to the client device at the selected bit rate.

2. The method of claim 1, further comprising simultaneously capturing multiple live streams of a plurality of programs.

3. The method of claim 1, wherein the captured segments include at least two bit rates for each time segment of the program.

4. The method of claim 1, further comprising:

creating a manifest file comprising information for playing back the captured segments, wherein the captured fragmented-type encoding segments are played back using the manifest file.

5. The method of claim 4, wherein the manifest file includes data regarding at least one layer, each layer comprising the captured segments in a respective bit rate different for each layer.

6. The method of claim 1, further comprising creating a poster image for the program from data provided by a content provider.

7. The method of claim 1, further comprising creating a poster image for the program by extracting the poster image from a frame of one of the captured segments.

8. The method of claim 1, further comprising creating a trailer for the program from at least one of the captured segments.

9. The method of claim 1, wherein the fragmented-type encoding includes adaptive bit rate encoding.

10. A system for converting a live fragmented-type encoding stream, the system comprising:

a cable head end configured to receive and broadcast media content from a content provider, the cable head end comprising;

a television grid guide configured to encode the media content with a fragmented-type encoding for broadcasting in at least one bitrate;

a video-on-demand (VOD) device in communication with the television grid guide, the VOD device comprising;

at least one processor; and

non-transitory computer readable media having encoded thereon computer software comprising a set of instructions executable by the at least one processor to;

receive, via a client interface, a request to record a broadcast video program;

determine when the program is to be broadcast;

capture, from the television grid guide, segments of a fragmented-type encoding live stream of the program at a time of broadcasting;

store, via the data storage unit, the captured segments of the fragmented-type encoding live stream of the program;

receive a request to view the program from client device in communication with the VOD device;

identify a type of a client device in communication with the VOD device; and

dynamically select a particular bitrate of the program for playback based on the type of the client device; and

play back the captured fragmented-type encoding segments to the client device at the selected bit rate.

11. The system of claim 10, wherein the television grid guide encodes the media content in at least two bit rates, and wherein the captured segments include the at least two bit rates of each time segment of the program.

12. The system of claim 11, wherein the set of instructions are further executable by the processor to:

create a manifest file comprising information for playing back the captured segments; and

play back the captured segments using the manifest file in response to receiving a request to view the program.

13. The system of claim 12, wherein the manifest file includes data regarding at least one layer, each layer comprising the captured segments in a respective bit rate different for each layer.

14. The system of claim 10, wherein the fragmented-type encoding includes adaptive bit rate encoding.

15. A system, comprising:

at least one processor; and

non-transitory computer readable media having encoded thereon computer software comprising a set of instructions executable by the at least one processor to;

receive a request to record a broadcast video program;

determine when the program is to be broadcast;

dynamically capture segments of fragmented-type encoding live stream of the program at a time of broadcasting;

store, in a data storage unit, the captured segments of the fragmented-type encoding live stream of the program;

receive a request from a client device to view the program;

identify a type of the client device;

dynamically select a particular bit rate of the program for playback based on the type of the client device;

play back the captured fragmented-type encoding segments to the client device at the selected bit rate.

16. The system of claim 15, wherein the set of instructions are further executable by the at least one processor to simultaneously capture segments of multiple fragmented-type encoding live streams of a plurality of programs.

17. The system of claim 15, wherein the captured segments include at least two bit rates of each time segment of the program.

18. The system of claim 15, wherein the fragmented-type encoding includes adaptive bit rate encoding.

19. The system of claim 15, wherein the set of instructions are further executable by the at least one processor to:

create a manifest file comprising information for playing back the captured segments; and

play back the captured segments using the manifest file in response to receiving a request to view the program.

20. The system of claim 19, wherein the manifest file includes data regarding at least one layer, each layer comprising the captured segments in a respective bit rate different for each layer.
