Abstract

An apparatus and method for display and control of video data on a mobile device provides simultaneous multiple video data display of groups of video sources and selection of video data for single, larger viewing. Control of the camera source of the video data is provided for the mobile device user, such as by manipulation of a multi-touch sensitive screen to pan, tilt and zoom. Image capture from the video screen and marking of the captured image is provided. Activation of video data streams and groups of video data streams for display on the mobile device is provided by transfer of activation information to the mobile device via email. Notification of events monitored by the video source or by other sensors is sent to users of the mobile devices.

Claims

1. An apparatus for display and control of video data, comprising:

a mobile client having a touch sensitive display, said mobile client being operable to connect to a wireless network over which is available video data; and

computer readable storage media in said mobile client having stored thereon a video command application, said video command application being operable to simultaneously display video data received over the wireless network from a plurality of video sources on said touch sensitive display, said video command application being operable to display video data from a single video source on said touch sensitive display, said video command application being operable to generate command instructions from user contact with said touch sensitive display to cause said single video source to change a characteristic of the video data being generated by the video source in accordance with the user contact.

2. An apparatus as claimed in claim 1, wherein said characteristic is at least one of pan, tilt, or zoom.

3. An apparatus as claimed in claim 1, wherein said touch sensitive display is a multi-touch sensitive display and wherein said video command application generates zoom commands for the single video source from multi-touch contact with said multi-touch sensitive display.

4. An apparatus as claimed in claim 1, wherein video command application groups said plurality of video sources into a plurality of groups, said simultaneous display displaying only video data of a single group.

5. An apparatus as claimed in claim 4, wherein said video command application is operable to flip pages of video data in a group, and wherein said video command application updates non-displayed video fields of the group on a periodic basis.

6. An apparatus as claimed in claim 1, wherein said mobile client is a first mobile client, and further comprising:

a further mobile client having a touch sensitive display and being operable to connect to a wireless network over which is available video data, said further mobile client being operable to transmit video source configuration information to said first mobile client; and

said first mobile client being operable to receive the video source configuration information and to display video data of the video source corresponding to the transmitted video source configuration information.

7. An apparatus as claimed in claim 1, wherein said simultaneous display displays video data of a predetermined number of video sources, said plurality of video sources exceeding said predetermined number being off-screen video sources that are not currently displayed on said simultaneous display, said off-screen video sources being updated with still images periodically.

8. A method of displaying and controlling video data on a mobile client, comprising the steps of:

receiving video data from a plurality of video sources;

displaying the video data as a simultaneous display of a plurality of video fields on a display panel of the mobile client;

displaying video data of a single video source as a single video display on the display panel of the mobile client in response to selection of one of the plurality of video fields by a user; and

controlling directional movement of said single video source in response to touch contact of the display panel by a user.

9. A method as claimed in claim 8, wherein said step of controlling directional movement includes:

receiving user contact with the display panel as a swipe having a direction;

translating the swipe contact into a camera movement command;

moving a camera in a direction corresponding the swipe contact, said camera being said single video source, said direction of moving said camera being one of pan and tilt; and

displaying video data from said camera after said moving step.

10. A method as claimed in claim 9, further comprising the steps of:

displaying an on screen icon in response to the user contact with the display panel;

receiving user contact at said icon; and

transmitting a continuous movement command to said camera as long as the user contacts remains at said icon.

11. A method as claimed in claim 8, further comprising the steps of:

receiving simultaneous multiple contact with the display panel by the user, said multiple contact including changing a distance between contact locations on said display panel; and

transmitting a zoom command to said single video source in response to the changing distance.

12. A method as claimed in claim 8, further comprising the steps of:

receiving a tap contact at the display panel from the user; and

transmitting a centering command to said single video source in response to the tap contact.

13. A method as claimed in claim 8, wherein said step of receiving video data received the video data over a network connection, further comprising the steps of:

monitoring latency over the network connection;

transmitting a command to a video source to reduce data volume of video data carried over the network if the latency exceeds a predetermined threshold.

14. A method as claimed in claim 13, wherein said command to reduce data volume includes at least one of:

reduce resolution of the video signal, increase compression of the video signal, and reduce frame rate of the video signal.

15. A method as claimed in claim 8, further comprising the steps of:

receiving a selection of video source definitions of a video source;

preparing an encrypted data bundle from said selected video source definitions;

transmitting the encrypted data bundle to a mobile client;

decrypting the encrypted data bundle in the mobile client;

viewing video data from the selected video source using the mobile client.

16. A method as claimed in claim 8, further comprising the steps of:

receiving groupings of video data sources into a plurality of groups;

receiving a label for each of the groups;

displaying the label for a selected group on the mobile client; and

displaying video data from the video data sources of the selected group on the mobile client.

17. A method as claimed in claim 8, further comprising the steps of:

displaying a predetermined number of video fields on the display panel as displayed video fields;

defining a group of video sources that are greater in number than said predetermined number;

displaying video data of the predetermined number of the video sources of the group in the displayed video fields;

associating the video sources of the group that are not being displayed in displayed video fields with background video fields;

updating the background video fields periodically with image data from the video sources;

receiving a command to change displayed video fields; and

in response to the command, displaying video data of the video sources associated with the background video fields in the displayed video fields and reassigning the video sources of the displayed video fields to background video fields.

18. A method as claimed in claim 17, wherein said command is a sliding contact movement on the display panel.

19. A method as claimed in claim 8, wherein said step of receiving video date includes receiving the video data wirelessly over a wireless communication that is at least one of a WiFi network and cellular network.

20. A method as claimed in claim 8, further comprising the steps of:

sensing a predetermined condition at a location;

generating an alert associated with the predetermined condition;

transmitting the alert to a user of a mobile client;

transmitting video source configuration information to the mobile client, the video source configuration information being for video sources providing video data at the location;

activating a video field on the mobile client for the video source at the location; and

displaying the video data of the location on the mobile client.

21. A method as claimed in claim 20, wherein said step of transmitting the alert includes transmitting the alert to the mobile client if the mobile client is connected to a server, and transmitting the alert as at least one of email and SMS message to the user if the mobile client is not connected to the server.
