Abstract

An apparatus and method for providing a virtual online live video channel is disclosed. The virtual video channel is generated without requiring a dedicated content provider and encoder for the channel. A schedule server stores a schedule for the virtual online live video channel, and the schedule may include one or more of live streaming video content, stored video content, and advertising. A video player establishes communication with a manifest server and requests playback of the video channel. The manifest server generates a per-user manifest file corresponding to the schedule of the video channel and delivers the per-user manifest file to the video player. The video player may then retrieve the desired video content from the content delivery network to produce the virtual online video channel.

Claims

1. A method for playback of a virtual online linear video channel, comprising:

generating a schedule for the virtual online linear video channel, wherein the virtual online linear video channel includes a plurality of video sources and each of the plurality of video sources is selected to distribute a video stream for at least a portion of the schedule;

generating a manifest file with a manifest server, the manifest file corresponding to the schedule for the virtual online linear video channel and identifying the selected video source from which the video stream is distributed at each portion of the schedule;

receiving a request to play the virtual online linear video channel from a video player; and

transmitting the manifest file to the video player.

2. The method of claim 1 wherein the plurality of video sources are selected from at least one of a live video stream, a video library, and an ad server.

3. The method of claim 2 wherein the plurality of video sources includes a first live video stream and a second live video stream, wherein each of the first and second live video streams is output from a separate encoder.

4. The method of claim 1 further comprising:

establishing a connection between the manifest server and the video player, wherein a session identifier identifies the connection; and

generating a per-user manifest file in the manifest server, wherein the per-user manifest file is generated as a function of the manifest file and the session identifier.

5. The method of claim 4 wherein one of the plurality of video sources is an ad server, the method further comprising:

selecting at least one advertisement from the ad server as a function of the session identifier; and

inserting the at least one advertisement in the schedule for the virtual online linear video channel.

6. The method of claim 1 wherein the generating of the schedule for the virtual online linear video channel further comprises:

displaying on an interface a list of the plurality of video sources available for inclusion in the schedule;

receiving an indication of at least two different video sources and a corresponding time for inclusion in the schedule; and

storing the schedule in a channel scheduler.

7. The method of claim 6 wherein a provider of at least one of the plurality of video sources enters the indication of the at least two different video sources and the corresponding time on the interface.

8. A system for providing a virtual online linear video channel, comprising:

a channel scheduler operative to;

receive a plurality of selections from a user interface, wherein each selection identifies a video source and a time for receiving the video source and wherein the plurality of selections identify at least two video sources,

generate a schedule for a video channel corresponding to the plurality of selections, and

store the schedule for the video channel; and

a manifest server, operative to;

receive a request to play the video channel from a video player,

obtain the schedule for the video channel from the schedule server,

generate a manifest file corresponding to the schedule, and

deliver the manifest file to the video player.

9. The system of claim 8 wherein each video source is selected from at least one of a live video stream, a video library, and an ad server.

10. The system of claim 9 wherein the at least two video sources includes a first live video stream and a second live video stream, wherein each of the first and second live video streams is output from a separate encoder.

11. The system of claim 8 wherein the manifest server is further operative to:

establish a connection with the video player, wherein a session identifier identifies the connection, and

generate a per-user manifest file as a function of the manifest file and the session identifier, wherein the per-user manifest file is delivered to the video player.

12. The system of claim 11 further comprising an ad server operative to:

store a plurality of advertisements;

receive a selection of at least one advertisement stored in the ad server as a function of the session identifier, and

transmit the at least one advertisement to an address for playback, wherein the manifest server is further operative to insert the address of the at least one advertisement in the manifest file for playback on the video player.

13. The system of claim 12 wherein the channel scheduler defines a plurality of time slots for advertisements and the ad server selects each of the at least one advertisement for insertion in the time slot.

14. The system of claim 11 further comprising a packager in communication with the manifest server and an ad server, the packager operative to:

read a playlist from the manifest file on the manifest server;

identify an entry in the playlist corresponding to an ad time slot; and

retrieve an advertisement stored in an ad server for playback during the identified ad time slot.

15. The system of claim 14 wherein the packager is further operative to store the advertisement at an address and the manifest server is further operative to store the address in the entry in the playlist prior to the video player retrieving the advertisement from the address.

16. The system of claim 8 wherein the channel scheduler includes an interface operative to:

display a list of each video source available for inclusion in the schedule; and

receive an indication of the at least two video sources and a corresponding time for inclusion in the schedule.

17. A method for playback of a virtual online linear video channel, comprising:

selecting a video channel for playback on a video player;

transmitting an indication of the selected video channel to a manifest server from the video player;

receiving at the video player a manifest file from the manifest server, wherein;

the manifest file is generated by the manifest server to correspond to a schedule of the selected video channel,

the schedule for the video channel identifies a plurality of video sources and each of the plurality of video sources is distributed on the video channel for at least a portion of the schedule, and

the manifest file identifies one of the plurality of video sources from which a video stream will be provided to the video player for each portion of the schedule.

18. The method of claim 17 further comprising entering an indication of each video source and a corresponding time for inclusion in the schedule using an interface executing on a channel scheduler.

19. The method of claim 18 wherein the channel scheduler inserts at least one ad time slot in the schedule for displaying an advertisement.

20. The method of claim 19 further comprising:

establishing a connection between the video player and the manifest server;

generating a session identifier corresponding to the connection; and

selecting an advertisement from an ad server for playback in the ad time slot as a function of the session identifier.
