Abstract

A method for providing video data for video analytics processing includes capturing a plurality of individual frames of video data, using a video source that is disposed at an acquisition end. A plurality of data-frame-groups is formed, each data-frame-group being associated with a different time period of a plurality of consecutive and non-overlapping time periods. A data-frame-group that is associated with a specific time period comprises individual frames of video data that are captured during that specific time period. Additionally, each data-frame-group comprises relatively fewer individual frames of video data than are captured during the specific time period associated therewith. The plurality of data-frame-groups is transmitted from the acquisition end to a remotely located server via an IP network. In particular, the transmission of successive data-frame-groups is separated one from the other by an interval of time.

Claims

1. A method comprising:

capturing video data using a video source disposed at an acquisition end, the video data comprising a plurality of individual frames of video data that are captured during a first period of time, the individual frames of video data being captured consecutively at a known frame rate;

forming a first data-frame-group comprising at least two individual frames of video data selected from the plurality of individual frames of video data, the first data-frame-group comprising relatively fewer individual frames of video data than the plurality of individual frames of video data;

transmitting the first data-frame-group from the acquisition end to a remotely located server via an IP network;

forming a second data-frame-group comprising at least two other individual frames of video data selected from the plurality of individual frames of video data, the second data-frame-group and the first data-frame-group in combination comprising fewer individual frames of video data than the plurality of individual frames of video data; and

,

transmitting the second data-frame-group from the acquisition end to a remotely located server via an IP network.

2. A method according to claim 1, comprising receiving the first data-frame-group at the server and performing video analytics processing on the video data of the first data-frame-group, wherein the video analytics processing is for detecting an occurrence of an actionable event during the first period of time.

3. A method according to claim 2, comprising in response to detecting an actionable event, transmitting to the acquisition end via the IP network a signal for requesting transmission of captured video data at the known frame rate.

4. A method according to claim 2, comprising storing at the acquisition end the plurality of individual frames of video data that are captured during the first period of time.

5. A method according to claim 4, comprising in response to detecting an actionable event, transmitting to the acquisition end via the IP network a signal for requesting stored video data that was captured prior to a time of transmission of the second data-frame-group.

6. A method according to any one of claims 1 to 5, wherein the first data-frame-group comprises a plurality of consecutively captured individual frames of video data selected from the plurality of individual frames of video data.

7. A method according to any one of claims 1 to 5, wherein the first data-frame-group comprises a plurality of non-consecutively captured individual frames of video data selected from the plurality of individual frames of video data.

8. A method according to claim 7, wherein the individual frames of the plurality of non-consecutively captured individual frames of video data are captured at approximately regular time intervals during the first period of time.

9. A method according to any one of claims 1 to 8, wherein each of the first data-frame-group and the second data-frame-group is limited to a predetermined maximum data size.

10. A method according to any one of claims 1 to 9, wherein the first data-frame-group is transmitted from the acquisition end to the remotely located server via the IP network during a second period of time that is subsequent to and not overlapping with the first period of time.

11. A method according to claim 1 wherein

the second data-frame-group is transmitted at a time separated from a time of transmission of the first data-frame-group by an interval of time other than a time interval between capturing a last frame of the first data-frame-group and a first frame of the second first data-frame-group.

12. A method according to claim 11, wherein the interval of time is predetermined, such that successive data-frame-groups are transmitted to the server via the IP network at approximately uniform time intervals.

13. A method according to claim 11, wherein the interval of time depends upon a maximum permitted size of the second data-frame-group and upon the sizes of the individual frames of the second plurality of individual frames of video data.

14. A method according to claim 11 or 12, wherein the first data-frame-group and the second data-frame-group each comprise a same number of individual frames of video data.

15. A method according to any one of claims 11 to 13, wherein the first data-frame-group and the second data-frame-group comprise a different number of individual frames of video data.

16. A method comprising:

capturing a plurality of individual frames of video data using a video source disposed at an acquisition end;

forming a plurality of data-frame-groups, each data-frame-group being associated with a different time period of a plurality of consecutive and non-overlapping time periods, such that a data-frame-group that is associated with a specific time period comprises individual frames of video data that are captured during that specific time period, and such that each data-frame-group comprises relatively fewer individual frames of video data than are captured during the specific time period associated therewith; and

,

transmitting the plurality of data-frame-groups from the acquisition end to a remotely located server via an IP network, the transmission of successive data-frame-groups being separated temporally by an interval of time greater than an interval of time between capturing of a last frame included within a first data-frame-group and a first frame of a temporally adjacent subsequent data-frame-group.

17. A method according to claim 16, wherein each data-frame-group of the plurality of data-frame-groups comprises a same number of individual frames of video data.

18. A method according to claim 16 or 17, wherein the interval of time is predetermined, such that successive data-frame-groups are transmitted to the server via the IP network at approximately uniform time intervals.

19. A method according to claim 16, wherein some of the data-frame-groups comprise a different number of individual frames of video data than other data-frame-groups of the plurality of data-frame-groups.

20. A method according to claim 16 or 19, wherein the interval of time depends upon a maximum permitted size of the second data-frame-group and upon the sizes of the individual frames of the second plurality of individual frames of video data.

21. A method according to claim 16, comprising receiving each data-frame-group of the plurality of data frame groups at the server and performing video analytics processing on the video data of each data-frame-group, wherein the video analytics processing is for detecting an occurrence of an actionable event.

22. A method according to claim 21, wherein the individual frames of video data are captured at a known frame rate, and comprising in response to detecting an actionable event, transmitting to the acquisition end via the IP network a signal for requesting transmission of captured video data at the known frame rate.

23. A method according to any one of claims 16 to 22, wherein the individual frames of video data of each data-frame-group are consecutively captured individual frames of video data

24. A method according to any one of claims 16 to 22, wherein the individual frames of video data of each data-frame-group are non-consecutively captured individual frames of video data.

25. A method according to any one of claims 16 to 24, comprising storing at the acquisition end the plurality of individual frames of video data.
