Abstract

An approach is provided for generating multi-channel video. A media platform segments a plurality of media items into one or more media segments based on a plurality of viewpoints of at least one event. The media platform then generates a plurality of media channels for respective one or more plurality of viewpoints. The plurality of media channels compiles the one or more media segments that depict the respective one or more of the plurality of viewpoints. The media platform then compiles the plurality of media channels into a multi-channel media item.

First claim

What is claimed is:

1. A method comprising:
generating a plurality of media channels from a plurality of media items created via one of a plurality of user devices, each media channel being for each of a plurality of viewpoints of at least one event, and said each media channel being configured to be selected by a user for viewing on a user device, wherein the plurality of media channels compiles a plurality of media segments that depict said each of the plurality of viewpoints of the at least one event;
compiling the plurality of media channels into a multi-channel media item;
processing the plurality of media items associated with the at least one event, context data associated with the plurality of media items, or a combination thereof to determine at least one region of interest for the at least one event,
wherein the at least one region of interest is determined to be a region or a viewpoint of the at least one event that a majority of the plurality of media items is focused on at a time said each of the plurality of media items is created, and
wherein the at least one region of interest is determined by analyzing areas of audio overlap among the one or more media segments; and
rendering a user interface for presenting the multi-channel media item for the at least one event,
wherein the user interface includes a plurality of user interface elements on a single screen, each user interface element representing a respective one of the plurality of media channels corresponding to a respective one of the plurality of viewpoints, and
wherein two or more of the plurality of user interface elements are activated to simultaneously display the two or more media channels corresponding to the activated two or more of the plurality of user interface elements.

2. A method of claim 1 , further comprising:
segmenting the plurality of media items into the plurality of media segments based, at least in part, on the plurality of viewpoints of the at least one event;
wherein the plurality of viewpoints of the at least one event is determined with the at least one region of interest as at least one reference point.

3. A method of claim 2 , further comprising:
designating the at least one region of interest as a central viewpoint; and
designating the plurality of viewpoints of the at least one event based on one or more ordinal directions from the central viewpoint,
wherein the one or more ordinal directions include, at least in part, left, right, up, down, front, back, or a combination thereof.

4. A method of claim 1 , further comprising:
selecting a subset of the plurality of media channels; and
multiplexing the subset into a single channel for presentation.

5. A method of claim 1 , wherein the plurality of media channels includes a same type of media, the method further comprising:
synchronizing the plurality of channels,
wherein the compiling the plurality of media channels into the multi-channel media item is based, at least in part, on the synchronization.

6. A method of claim 5 , wherein the synchronizing is based, at least in part, on timing information, sensor information, media quality information, one or more audio cues, one or more visual cues, or a combination thereof associated with the plurality of media items, the plurality of media segments, the at least one event, or a combination thereof.

7. A method of claim 5 , further comprising:
determining synchronization criteria for the synchronizing,
wherein the synchronization criteria, one or more synchronization start times, one or more synchronization end times, or a combination thereof are different for respective ones of the plurality of channels.

8. A method of claim 1 , further comprising:
determining a plurality of editing parameters for compiling the plurality of media segments in the plurality of media channels based, at least in part, on a plurality of characteristics of (a) the at least one event, (b) the plurality of media items, (c) the plurality of media segments, or (d) a combination thereof.

9. An apparatus comprising:
at least one processor; and
at least one non-transitory memory carrying one or more sequences of one or more instructions which, when executed by the at least one processor, cause the apparatus to perform at least following,
cause, at least in part, a generation of a plurality of media channels from a plurality of media items created via one of a plurality of user devices, each media channel being for each of a plurality of viewpoints of at least one event, and said each media channel being configured to be selected by a user for viewing on a user device, wherein the plurality of media channels compiles a plurality of media segments that depict said each of the plurality of viewpoints of the at least one event;
cause, at least in part, a compilation of the plurality of media channels into a multi-channel media item;
process and/or facilitate a processing of the plurality of media items associated with the at least one event, context data associated with the plurality of media items, or a combination thereof to determine at least one region of interest for the at least one event,
wherein the at least one region of interest is determined to be a region or a viewpoint of the at least one event that a majority of the plurality of media items is focused on at a time said each of the plurality of media items is created, and
wherein the at least one region of interest is determined by analyzing areas of audio overlap among the one or more media segments; and
rendering a user interface for presenting the multi-channel media item for the at least one event,
wherein the user interface includes a plurality of user interface elements on a single screen, each user interface element representing a respective one of the plurality of media channels corresponding to a respective one of the plurality of viewpoints, and
wherein two or more of the plurality of user interface elements are activated to simultaneously display the two or more media channels corresponding to the activated two or more of the plurality of user interface elements.

10. An apparatus of claim 9 , wherein the apparatus is further caused to:
cause, at least in part, a segmentation of the plurality of media items into the plurality of media segments based, at least in part, on the plurality of viewpoints of the at least one event;
wherein the plurality of viewpoints of the at least one event is determined with the at least one region of interest as at least one reference point.

11. An apparatus of claim 10 , wherein the apparatus is further caused to:
determine to designate the at least one region of interest as a central viewpoint; and
determine to designate the plurality of viewpoints of the at least one event based on one or more ordinal directions from the central viewpoint,
wherein the one or more ordinal directions include, at least in part, left, right, up, down, front, back, or a combination thereof.

12. An apparatus of claim 9 , wherein the apparatus is further caused to:
determine an input for selecting a subset of the plurality of media channels; and
cause, at least in part, a multiplexing of the subset into a single channel for presentation.

13. An apparatus of claim 9 , wherein the plurality of media channels includes a same type of media, and wherein the apparatus is further caused to:
cause, at least in part, a synchronization of the plurality of channels,
wherein the compilation of the plurality of media channels into the multi-channel media item is based, at least in part, on the synchronization.

14. An apparatus of claim 13 , wherein t
