Abstract

A method of enabling a user to access recorded data associated with an event, the method comprising determining the location of a user'"'"'s device at a control unit, confirming the location is within a predetermined vicinity and that the user'"'"'s device was at the location within a predetermined period and the control unit enabling access for the user to the data if the location of the user'"'"'s device in the predetermined period is confirmed.

Claims

1. A method of providing access to recorded data associated with an event, the method comprising:

determining, by a control unit, a location of a device;

confirming the location is within a predetermined vicinity coincident with the event and that the device was at the location within a time period associated with the event;

receiving a request for at least a portion of recorded data associated with the event, the request being associated with the device;

receiving at least one additional request for at least the portion of the recorded data;

consolidating the request and the at least one additional request into a single request;

extracting a portion of the recorded data, wherein the extracted portion of the recorded data includes a time window relative to a time of the request, the time window including a first time before the time of the request and a second time after the time of the request;

generating, for the single request, a common media file for the extracted portion of the recorded data; and

providing the device for a first user, and at least one additional device for a second user, with access to the common media file for the extracted portion of the recorded data based on confirming that at least one of the device or the at least one additional device was at the location within the time period.

2. The method of claim 1, wherein the recorded data is a video recording of at least part of the event recorded by at least one camera, the at least one camera being located at a location of the event.

3. The method claim 1, further comprising:

receiving location information associated with the device; and

determining the location of the device during the event using the location information.

4. The method of claim 1, further comprising:

determining a number of requests associated with one or more portions of the recorded data;

selecting one or more clips from the recorded data to include in a collection of clips, the one or more clips being selected based on the number of requests; and

providing at least one of the device or the at least one additional device with access to the collection of clips.

5. The method of claim 1, wherein the recorded data is stored in a buffer configured to store data for a period of time.

6. The method of claim 5, further comprising:

transferring, to a memory, at least some of the recorded data stored in the buffer at the time of the request; and

storing subsequent data recorded after the request in the memory.

7. The method of claim 1, wherein the access to the recorded data is provided to at least one of the device or the at least one additional device by a link.

8. The method of claim 7, wherein the link is transmitted from the control unit in response to at least one of the request or the at least one additional request.

9. The method of claim 1, wherein the time window of the extracted portion is configurable based on one or more additional requests.

10. The method of claim 1, wherein the extracted portion of the recorded data is determined based on the location of the device.

11. The method of claim 1, wherein one or more usage rules are applied to the recorded data such that access to the recorded data is restricted.

12. A system for providing access to recorded data associated with an event, the system comprising:

one or more processors; and

memory accessible to the processor, the memory storing instructions, which upon execution by the one or more processors, cause the one or more processors to perform operations to;

determine a location of a device;

confirm the location is within a predetermined vicinity coincident with the event and that the device was at the location within a time period associated with the event;

receive a request for at least a portion of recorded data associated with the event, the request being associated with the device;

receive at least one additional request for at least the portion of the recorded data;

consolidate the request and the at least one additional request into a single request;

extract a portion of the recorded data, wherein the extracted portion of the recorded data includes a time window relative to a time of the request, the time window including a first time before the time of the request and a second time after the time of the request;

generate, for the single request, a common media file for the extracted portion of the recorded data; and

provide the device for a first user, and at least one additional device for a second user, with access to the common media file for the extracted portion of the recorded data based on confirming that at least one of the device or the at least one additional device was at the location within the time period.

13. The system of claim 12, wherein the recorded data is a video recording of at least part of the event recorded by at least one camera, the at least one camera being located at a location of the event.

14. The system of claim 12, the memory further storing instructions, which upon execution by the one or more processors, cause the one or more processors to perform operations to:

receive location information associated with the device; and

determine the location of the device during the event using the location information.

15. The system of claim 12, the memory further storing instructions, which upon execution by the one or more processors, cause the one or more processors to perform operations to:

determine a number of requests associated with one or more portions of the recorded data;

select one or more clips from the recorded data to include in a collection of clips, the one or more clips being selected based on the number of requests; and

provide at least one of the device or the at least one additional device with access to the collection of clips.

16. The system of claim 12, wherein the recorded data is stored in a buffer configured to store data for a period of time.

17. The system of claim 16, further comprising a memory, and wherein:

at least some of the recorded data stored in the buffer is transferred to the memory at the time of the request; and

subsequent data recorded after the request is stored in the memory.

18. The system of claim 12, wherein the access to the recorded data is provided to at least one of the device and the at least one additional device by a link.

19. The system of claim 12, wherein the time window of the extracted portion is configurable based on one or more additional requests.
