Remote presentation with augmented reality content synchronized with separately displayed video content
Augmented reality systems provide graphics over views from a mobile device for both in-venue and remote viewing of a sporting or other event. A server system can provide a transformation between the coordinate system of a mobile device (mobile phone, tablet computer, head mounted display) and a real world coordinate system. Requested graphics for the event are displayed over a view of an event. In a tabletop presentation, video of the event can be displayed with augmented reality graphics overlays at a remote location.
1 . A method, comprising:
receiving, at a system of one or more processors from a broadcaster, video of an event at a venue;
receiving, at the system, video captured by a first mobile device of the video of the event from the broadcaster as displayed on a television at a location remote from the venue;
performing by the system of a comparison of the video received at the system from the broadcaster with the video captured by the first mobile device;
determining, by the system based on the comparison, a time synchronization point for a presentation of the event by the first mobile device at the location remote from the venue that is synchronized with the video of the event displayed on the television at the location remote from the venue; and
sending the time synchronization point and the presentation of the event from the system to the first mobile device.
2 . The method of claim 1 , further comprising:
generating a hash of the video received from the broadcaster; and
generating a hash of the video captured by the first mobile device, wherein the comparison by the system of the video received at the system from the broadcaster with the video captured by the first mobile device is performed as a comparison between the hash the video received from the broadcaster and the hash the video captured by the first mobile device.
3 . The method of claim 2 , further comprising:
storing the hash of the video received from the broadcaster in a circular buffer, wherein the comparison between the hash the video received from the broadcaster and the hash the video captured by the first mobile device is performed using the hash the video received from the broadcaster stored in the circular buffer.
4 . The method of claim 1 , further comprising:
including a known amount of delay for the video from a broadcaster into determining the time synchronization point.
5 . The method of claim 1 , wherein the video from a broadcaster is received from an over-the-top server in an internet protocol.
6 . The method of claim 1 , wherein the video captured by the first mobile device is of a lower fidelity than the video from the broadcaster as displayed on a television.
7 . The method of claim 1 , further comprising:
determining, based on the comparison, a delay value for the video from the broadcaster as displayed on a television; and
sending to the television the delay value.
8 . The method of claim 1 , wherein the television and the first mobile device are at a first location, the method further comprising:
sending the time synchronization point from the system to one or more additional mobile devices at the first location.
9 . The method of claim 1 , further comprising:
sending augmented reality content related to the video from the broadcaster from the system to the first mobile device.
10 . A system, comprising:
one or more servers configured to receive data from and transmit data to one or more mobile devices and to:
receive from a broadcaster video of an event at a venue;
receive video captured by a first of the one or more mobile devices of the video of the event from the broadcaster as displayed on a television at a location remote from the venue;
perform a comparison of the received video from the broadcaster with the video captured by the first mobile device;
based on the comparison, determine a time synchronization point for a presentation of the event by the first mobile device at the location remote from the venue that is synchronized with the video of the event displayed on the television at the location remote from the venue; and
send the time synchronization point and the presentation of the event to the first mobile device.
11 . The system of claim 10 , wherein the one or more servers are further configured to:
generate a hash of the video received from the broadcaster; and
generate a hash of the video captured by the first mobile device, wherein the comparison by the system of the video received at the system from the broadcaster with the video captured by the first mobile device is performed as a comparison between the hash the video received from the broadcaster and the hash the video captured by the first mobile device.
12 . The system of claim 11 , wherein the one or more servers are further configured to:
store the hash of the video received from the broadcaster in a circular buffer, wherein the comparison between the hash the video received from the broadcaster and the hash the video captured by the first mobile device is performed using the hash the video received from the broadcaster stored in the circular buffer.
13 . The system of claim 10 , wherein the video captured by the first mobile device of the video is of a lower fidelity than the video from the broadcaster as displayed on a television.
14 . The system of claim 10 , wherein the television and the first mobile device are at a first location, wherein the one or more servers are further configured to:
send the time synchronization point from the system to one or more additional mobile devices at the first location.
15 . A method, comprising:
capturing by a mobile device of video content from a broadcaster of video of an event at a venue as displayed on a television at a location remote from the venue;
sending the captured video content from the mobile device to a system of one or more servers;
in response to sending the captured video content to the system, receiving by the mobile device from the system of a time synchronization point for a presentation of the event by the first mobile device at the location remote from the venue that is synchronized with the video of the event displayed on the television at the location remote from the venue;
receiving by the mobile device of augmented reality content related to the video content, including the presentation of the event, from the system of one or more servers; and
displaying by the mobile device of the augmented reality content related to the video content synchronized with the video content as displayed on the television based on the time synchronization point.
16 . The method of claim 15 , wherein the augmented reality content related to the video content includes three dimensional video content.
17 . The method of claim 16 , wherein the augmented reality content related to the video content includes augmented reality graphics to overlay the three dimensional video content.
18 . The method of claim 15 , wherein the video content captured by the mobile device is of a lower fidelity than the video from the broadcaster as displayed on a television.
19 . The method of claim 15 , wherein the mobile device is an augmented reality headset.
20 . The method of claim 15 , wherein the mobile device is a mobile phone.
