Abstract

An approach for providing access to live video data from a plurality of cameras in a DVM system. The approach may incorporate maintaining, for each camera, data indicative of relatedness scores for one or more other cameras in the DVM system. The approach may also incorporate providing functionality via the user interface thus enabling convenient access to one or more cameras with highest relatedness scores for a camera that is currently being viewed by a user.

Claims

1. A computer implemented method for providing access to live video data from a plurality of cameras in a DVM system, the method including:

maintaining data indicative of cameras in a hierarchical structure;

receiving, from a user of a client terminal, a command indicative of;

an instruction to generate a multi-camera view; and

a defined selection of cameras defined by reference to the hierarchical structure;

in response to the command, defining a camera workspace view for rendering at the client terminal, wherein the camera workspace view is configured to provide a plurality of video display objects that are respectively configured to display live video data from the defined selection of cameras.

2. A method according to claim 1 wherein the hierarchical structure is defined by a tree structure including a plurality of nodes, and wherein the command is indicative of a user-selected one or more of the nodes, wherein the defined selection of cameras consists of all cameras nested beneath the user-selected one or more nodes.

3. A method according to claim 1 wherein the camera workspace view is defined by a plurality of workspace pages, with the number of workspace pages being defined based upon the quantity of cameras in the defined selection of cameras.

4. A method according to claim 3 wherein the camera workspace view is configured to, when rendered at the client terminal, periodically cycle between the plurality of workspace pages.

5. A method according to claim 1 including, upon rendering of the camera workspace view at the client terminal, managing streaming characteristics of the defined selection of cameras based on a predefined protocol.

6. A method according to claim 5 wherein the predefined protocol operates thereby to enable streaming at a first rate for a first set of the defined selection of cameras and a second rate that is less bandwidth intensive than the first rate for a second set of the defined selection of cameras.

7. A method according to claim 6 wherein the first set includes cameras currently displayed on-screen client terminal, and the second set includes cameras currently represented in the camera workspace view but not currently displayed on-screen at the client terminal.

8. A method according to claim 1 including a step of enabling a user to save the camera workspace view, thereby to allow subsequent access to the saved camera workspace view.

9. A method according to claim 8 including a step of enabling a user to modify the camera workspaces view by one or more of the following:

adding one or more additional cameras;

removing one or more cameras; and

resizing the video display objects.

10. A method according to claim 1 including selecting a video display object size based on one or more characteristics of the defined selection of cameras.

11. A method for providing access to live video data from a plurality of cameras in a DVM system, the method including

maintaining, for each camera, data indicative of relatedness scores for one or more other cameras in the DVM system;

and

providing functionality via the user interface thereby to enable convenient access to one or more cameras with highest relatedness scores for a camera that is currently being viewed by a user.

12. A method according to claim 11 including:

monitoring user activity in the DVM system;

maintaining data indicative of a set of observable actions and a set of score adjustment rules; and

upon monitoring one of the observable actions relating to a target camera and a second camera, updating, for the target camera, the relatedness score for the second camera based on the score adjustment rules.

13. A method according to claim 11 including providing a user interface component configured to display, for a camera in respect of which live video data is currently being displayed, data indicative of cameras having the highest relatedness scores for that camera.

14. A method according to claim 11 wherein, for a given camera, the score adjustment rules include any one or more of the following:

a rule to increase the relatedness score where a camera is viewed immediately preceding the given camera;

a rule to increase the relatedness score where a camera is viewed immediately following the given camera; and

a rule to increase the relatedness score where a camera is viewed concurrently with the given camera.

15. A method according to claim 11, the method including:

monitoring a user interface component that is configured to provide one or more video display objects, wherein each video display object is configured to provide live video data for an associated one of the cameras;

identifying, for a given one of the cameras for which one of the video display object is configured to provide live video data, a set of related cameras; and

updating a related cameras display object thereby to display data indicative of the set of related cameras.

16. A DVM system configured to enable access to a plurality of cameras, the system being configured to perform either or both of:

a method for providing access to live video data from a plurality of cameras in a DVM system, the method including;

(a) maintaining data indicative of cameras in a hierarchical structure;

receiving, from a user of a client terminal, a command indicative of;

an instruction to generate a multi-camera view; and

a defined selection of cameras defined by reference to the hierarchical structure; and

(b) in response to the command, defining a camera workspace view for rendering at the client terminal, wherein the camera workspace view is configured to provide a plurality of video display objects that are respectively configured to display live video data from the defined selection of cameras; and

a method for providing access to live video data from a plurality of cameras in a DVM system, the method including;

(a) maintaining, for each camera, data indicative of relatedness scores for one or more other cameras in the DVM system; and

(b) providing functionality via the user interface thereby to enable convenient access to one or more cameras with highest relatedness scores for a camera that is currently being viewed by a user.

17. A DVM system according to claim 16 wherein the camera workspace view is defined by a plurality of workspace pages, with the number of workspace pages being defined based upon the quantity of cameras in the defined selection of cameras.

18. A DVM system according to claim 16 wherein, upon rendering of the camera workspace view at the client terminal, streaming characteristics of the defined selection of cameras based are managed thereby to enable streaming at a first rate for a first set of the defined selection of cameras and a second rate that is less bandwidth intensive than the first rate for a second set of the defined selection of cameras, wherein the first set includes cameras currently displayed on-screen client terminal, and the second set includes cameras currently represented in the camera workspace view but not currently displayed on-screen at the client terminal.

19. A DVM system according to claim 16 wherein a component is configured to:

monitor user activity in the DVM system;

maintain data indicative of a set of observable actions and a set of score adjustment rules; and

upon monitoring one of the observable actions relating to a target camera and a second camera, update, for the target camera, the relatedness score for the second camera based on the score adjustment rules.

20. A DVM system according to claim 16 wherein a component is configured to:

monitor a user interface component that is configured to provide one or more video display objects, wherein each video display object is configured to provide live video data for an associated one of the cameras;

identify, for a given one of the cameras for which one of the video display object is configured to provide live video data, a set of related cameras; and

update a related cameras display object thereby to display data indicative of the set of related cameras.
