Abstract

There is provided a system and method for rule-based dynamic server-side streaming manifest files. There is provided a method comprising receiving a request to provide a first video content for playback, evaluating a plurality of rules for the first video content, generating a dynamic manifest file referencing the first video content, and providing the dynamic manifest file in response to the request, thereby enabling an application to playback the first video content for output on a display by interpreting the dynamic manifest file. The rules may implement various features such as dynamic advertisement insertion, load balancing, client customization, user and device targeting, enhanced security mechanisms, global announcements, and others. As streaming protocols are widely supported by default on many client platforms, the dynamic manifest files can be utilized in a user friendly and transparent manner compared to client-side solutions requiring cumbersome client software installations.

Claims

1. A server for providing rule-based dynamic server-side streaming manifest files to enable flexible video playback, the server comprising:

a processor configured to;

receive, from an application executing on a first client device, a request to provide a first video content for playback;

evaluate a plurality of rules for the first video content;

generate a dynamic manifest file referencing a plurality of content video segments corresponding to the first video content; and

provide the dynamic manifest file to the application in response to the request, thereby enabling the application to playback the first video content for output on a display by interpreting the dynamic manifest file.

2. The server of claim 1, wherein the plurality of rules includes processing the plurality of content video segments according to a parameter of the first client device.

3. The server of claim 1, wherein the plurality of rules includes processing the plurality of content video segments according to a parameter of the display.

4. The server of claim 1, wherein the plurality of rules includes specifying a content delivery network hosting the plurality of content video segments according to load balancing parameters applied to the first client device, and wherein the processor is further configured to generate the dynamic manifest file by referencing the specified content delivery network.

5. The server of claim 1, wherein the plurality of rules includes selecting a plurality of advertisement video segments for the first client device, and wherein the processor is further configured to generate the dynamic manifest file by further referencing the plurality of advertisement video segments.

6. The server of claim 5, wherein the selecting is by evaluating a user tracking profile associated with the first client device.

7. The server of claim 5, wherein prior to generating the dynamic manifest file the processor is further configured to:

process the plurality of video segments by cutting one or more of the plurality of video segments such that the dynamic manifest file is enabled to reference each of the plurality of advertisement video segments at any playback offset.

8. The server of claim 1, wherein the processor is further configured to:

update the dynamic manifest file to reference additional content video segments comprising live video content, thereby enabling the application to live stream video content for output on the display by periodically retrieving and reinterpreting the dynamic manifest file.

9. The server of claim 1, wherein the dynamic manifest file comprises a playlist in the M3U8 format, and wherein the plurality of content video segments comprise MPEG transport stream (TS) file fragments.

10. The server of claim 1, wherein the processor is further configured to:

receive a request to provide a plurality of priority video segments for playback on a plurality of client devices;

modify a plurality of dynamic manifest files associated with the plurality of client devices to reference the plurality of priority video segments; and

provide the plurality of dynamic manifest files to the plurality of client devices, thereby enabling concurrent playback of the plurality of priority video segments for output on a plurality of displays associated with the plurality of client devices.

11. A method for providing rule-based dynamic server-side streaming manifest files to enable flexible video playback, the method comprising:

receiving, from an application executing on a first client device, a request to provide a first video content for playback;

evaluating a plurality of rules for the first video content;

generating a dynamic manifest file referencing a plurality of content video segments corresponding to the first video content; and

providing the dynamic manifest file to the application in response to the request, thereby enabling the application to playback the first video content for output on a display by interpreting the dynamic manifest file.

12. The method of claim 11, wherein the plurality of rules includes processing the plurality of content video segments according to a parameter of the first client device.

13. The method of claim 11, wherein the plurality of rules includes processing the plurality of content video segments according to a parameter of the display.

14. The method of claim 11, wherein the plurality of rules includes specifying a content delivery network hosting the plurality of content video segments according to load balancing parameters applied to the first client device, and wherein the generating of the dynamic manifest file further comprises referencing the specified content delivery network.

15. The method of claim 11, wherein the plurality of rules includes selecting a plurality of advertisement video segments for the first client device, and wherein the generating of the dynamic manifest file further comprises referencing the plurality of advertisement video segments.

16. The method of claim 15, wherein the selecting is by evaluating a user tracking profile associated with the first client device.

17. The method of claim 15 further comprising prior to the generating of the dynamic manifest file:

processing the plurality of video segments by cutting one or more of the plurality of video segments such that the dynamic manifest file is enabled to reference each of the plurality of advertisement video segments at any playback offset.

18. The method of claim 11 further comprising:

updating the dynamic manifest file to reference additional content video segments comprising live video content, thereby enabling the application to live stream video content for output on the display by periodically retrieving and reinterpreting the dynamic manifest file.

19. The method of claim 11, wherein the dynamic manifest file comprises a playlist in the M3U8 format, and wherein the plurality of content video segments comprise MPEG transport stream (TS) file fragments.

20. The method of claim 11 further comprising:

receiving a request to provide a plurality of priority video segments for playback on a plurality of client devices;

modifying a plurality of dynamic manifest files associated with the plurality of clients to reference the plurality of priority video segments; and

providing the plurality of dynamic manifest files to the plurality of client devices, thereby enabling concurrent playback of the plurality of priority video segments for output on a plurality of displays associated with the plurality of client devices.
