Abstract

Systems and methods related to a mobile device video wall are disclosed. In some embodiments, a mobile device operates to obtain one or more media files that contain partial-frame video content for a grid location in a video grid for a mobile device video wall. The mobile device further operates to provide playout of partial-frame video content for the grid location such that the playout of the partial-frame video content for the grid location by the mobile device is synchronized to playout of partial-frame video content for other grid locations in the video grid by other mobile devices in the mobile device video wall.

First claim

What is claimed is:

1. A method of operation of a mobile device to provide playout of full-frame video content for a mobile device video wall, the method comprising:
obtaining one or more media files that contain partial-frame video content for a grid location in a video grid for the mobile device video wall, wherein:
the video grid divides each frame of the full-frame video content into a plurality of frame areas each corresponding to a different one of a plurality of grid locations in the video grid such that the partial-frame video content for the grid location consists of video content from a corresponding frame area of the plurality of frame areas of the full-frame video content;
each grid location of the video grid corresponds to a different set of one or more physical locations of mobile devices within the mobile device video wall;
the grid location for which the one or more media files are obtained is one of the plurality of grid locations that corresponds to a physical location of the mobile device; and
the partial-frame video content for the grid location comprises partial-frame video content corresponding to each of a plurality of times in the playout; and

providing playout of the partial-frame video content for the grid location such that the playout of the partial-frame video content for the grid location corresponding to the plurality of times by the mobile device is synchronized to playout of partial-frame video content for other grid locations in the video grid by other mobile devices in the mobile device video wall.

2. The method of claim 1 , further comprising:
receiving a notification that indicates a time at which the playout of the partial-frame video content for the grid location is to begin,
wherein providing the playout of the partial-frame video content for the grid location comprises providing the playout of the partial-frame video content beginning at the time indicated by the notification.

3. The method of claim 2 , wherein the notification is a multicast notification.

4. The method of claim 1 , further comprising:
receiving a multicast notification address:port;
joining a multicast at the multicast notification address:port; and
receiving a multicast notification via the multicast on the multicast notification address:port that indicates a time at which the playout of the partial-frame video content for the grid location is to begin,
wherein providing the playout of the partial-frame video content for the grid location comprises providing the playout of the partial-frame video content beginning at the time indicated by the multicast notification.

5. The method of claim 4 , further comprising:
sending location information to a remote system that is indicative of the physical location of the mobile device; and
receiving one or more uniform resource locators for the one or more media files from the remote system in response to sending the location information,
wherein obtaining the one or more media files that contain the partial-frame video content for the grid location comprises obtaining the one or more media files that contain the partial-frame video content for the grid location using the one or more uniform resource locators.

6. The method of claim 1 , further comprising, after the playout of the full-frame video content by the mobile device video wall has begun:
receiving a notification that indicates a master player playout timing for the full-frame video content,
wherein providing the playout of the partial-frame video content for the grid location comprises providing the playout of the partial-frame video content according to the master player playout timing such that the playout of the partial-frame video content begins at an appropriate playout location within the partial-frame video content to synchronize playout at the mobile device with playout at the other mobile devices in the mobile device video wall.

7. The method of claim 6 , wherein the notification is a multicast notification.

8. The method of claim 1 , further comprising:
receiving a multicast notification address:port;
joining a multicast at the multicast notification address:port; and
receiving a multicast notification via the multicast on the multicast notification address:port that indicates a master player playout timing at which the partial-frame video content for the grid location is to begin,
wherein providing the playout of the partial-frame video content for the grid location comprises providing the playout of the partial-frame video content according to the master player playout timing such that the playout of the partial-frame video content begins at an appropriate playout location within the partial-frame video content to synchronize playout at the mobile device with playout at the other mobile devices in the mobile device video wall.

9. A mobile device enabled to operate, along with a plurality of other mobile devices, to provide playout of full-frame video content as a mobile device video wall, the mobile device comprising:
a display;
one or more processors; and
memory containing software executable by the one or more processors, whereby the mobile device is operative to:
obtain one or more media files that contain partial-frame video content for a grid location of a video grid for the mobile device video wall, wherein:
the video grid divides each frame of the full-frame video content into a plurality of frame areas each corresponding to a different one of a plurality of grid locations in the video grid such that the partial-frame video content for the grid location consists of video content from a corresponding frame area of the plurality of frame areas of the full-frame video content;
each grid location of the video grid corresponds to a different set of one or more physical locations of mobile devices within the mobile device video wall;
the grid location for which the one or more media files are obtained is one of the plurality of grid locations that corresponds to a physical location of the mobile device; and
the partial-frame video content for the grid location comprises partial-frame video content corresponding to each of a plurality of times in the playout; and

provide playout of the partial-frame video content for the grid location on the display such that the playout of the partial-frame video content for the grid location corresponding to the plurality of times by the mobile device is synchronized to playout of partial-frame video content for other grid locations in the video grid by the other mobile devices in the mobile device video wall.

10. A method of operation of a server system comprising one or more server computers to provide playout of full-frame video content by a mobile device video wall, the method comprising:
for each mobile device of a plurality of mobile devices comprised in the mobile device video wall, delivering one or more media files that contain partial-frame video content for a grid location in a video grid for the mobile device video wall, wherein:
the video grid divides each frame of the full-frame video content into a plurality of frame areas each corresponding to a different one of a plurality of grid locations in the video grid such that the partial-frame video content for the grid location consists of video content from a corresponding frame area of the plurality of frame areas of the full-frame video content;
each grid location of the video grid corresponds to a different set of one or more physical locations of mobile devices within the mobile device video wall;
the grid location for which the one or more media files are delivered to the mobile device is one of the plurality of grid locations that corresponds to a physical
