Abstract

Disclosed is a method for video monitoring based on Universal Plug and Play (UPnP), comprising the steps of: a camera device saves an improved Digital Media Server (DMS) function; after receiving the request transmitted by a Digital Media Control (DMC) device, for obtaining the video stream, the camera device analyzes the request for obtaining video stream by the improved DMS function and then starts camera shooting. Also disclosed is a device and system for video monitoring based on UPnP. The present invention can provide function of real-time video monitoring in the UPnP network architecture.

Claims

1. A method for video monitoring based on Universal Plug and Play (UPnP), comprising:

by a camera device, receiving a request of acquiring a video stream from a Digital Media Control (DMC) device, wherein there is an improved Digital Media Sever (DMS) function saved on the camera device; and

by the camera device, starting shooting after the camera device parses the request of acquiring the video stream by using the improved DMS function.

2. The method according to claim 1, wherein the improved DMS function comprises:

an existing DMS function and a rule of parsing a camera-device-related control instruction,

wherein the rule of parsing the camera-device-related control instruction comprises that;

the request of acquiring the video stream is parsed in a Simple Object Access Protocol (SOAP) format, and an instruction of rotating a camera of the camera device is parsed in an Extensible Markup Language (XML) format.

3. The method according to claim 1, further comprising:

before the camera device receives the request of acquiring the video stream from the DMC device,

receiving, by the camera device, a camera-device-query message from the DMC device; and

returning, by the camera device, a response message for the camera-device-query message to the DMC device.

4. The method according to claim 1, further comprising:

after the shooting is started,

adjusting, by the camera device, an angle of a camera of the camera device according to an instruction of rotating the camera from the DMC device.

5. The method according to claim 1, further comprising:

before the camera device receives the request of acquiring the video stream from the DMC device,

by the DMC device, writing the request of acquiring the video stream by using an improved DMC function saved on the DMC device and sending the request of acquiring the video stream to the camera device.

6. The method according to claim 5, wherein the improved DMC function comprises:

an existing DMC function and a rule of writing a camera-device-related control instruction,

wherein the rule of writing the camera-device-related control instruction comprises that;

the request of acquiring the video stream is written in an SOAP format and an instruction of rotating a camera of the camera device is written in an XML format.

7. The method according to claim 5, further comprising:

before the DMC device writes the request of acquiring the video stream by using the improved DMC function,

by the DMC device, sending a camera-device-query message to the camera device and receiving a response message for the camera-device-query message from the camera device.

8. The method according to claim 5, further comprising:

after the request of acquiring the video stream is sent to the camera device,

when the camera device supports a rotation function, sending, by the DMC device, an instruction of rotating a camera of the camera device to the camera device.

9-13. -13. (canceled)

14. A camera device, comprising:

an improved DMS function module and a shooting function module,

wherein the improved DMS function module is configured to save an improved DMS function, parse a request of acquiring a video stream from a DMC device by using the improved DMS function, and notify the shooting function module to start shooting according to the request, and

wherein the shooting function module is configured to start shooting according to the notification from the improved DMS function module.

15. The camera device according to claim 14, wherein the improved DMS function module is configured to save an existing DMS function and a rule of parsing a camera-device-related control instruction,

wherein the rule of parsing the camera-device-related control instruction comprises that:

the request of acquiring the video stream is parsed in an SOAP format, and an instruction of rotating a camera of the camera device is parsed in an XML format.

16. The camera device according to claim 15, wherein

the improved DMS function module is further configured to, when receiving a camera-device-query message from the DMC device, return a response message for the camera-device-query message to the DMC device.

17. The camera device according to claim 16, wherein the improved DMS function module is further configured to notify a shooting control module to adjust an angle of the camera according to the instruction of rotating the camera of the camera device from the DMC device, and

wherein the shooting control module is configured to receive the notification from the improved DMS function module and adjust the angle of the camera according to the notification.

18. A DMC device, comprising:

an improved DMC function module, which is configured to save an improved DMC function, write a request of acquiring a video stream by using the improved DMC function and send the request of acquiring the video stream to a camera device.

19. The DMC device according to claim 18, wherein the improved DMC function module is configured to save an existing DMC function and a rule of writing a camera-device-related control instruction, and

wherein the rule of writing the camera-device-related control instruction comprises that:

the request of acquiring the video stream is written in an SOAP format, and an instruction of rotating a camera of the camera device is written in an XML format.

20. The DMC device according to claim 19, wherein the improved DMC function module is further configured to send a camera-device-query message to the camera device and receive a response message for the camera-device-query message from the camera device.

21. The DMC device according to claim 20, wherein the improved DMC function module is further configured to send an instruction of rotating the camera of the camera device to the camera device when the camera device supports a rotation function.
