Abstract

A data and image transmission system includes at least one interactive control server system, coupled to a communications network, to which a user may connect for interactive communication to at least one remote image-data acquisition system located behind a communications security firewall. The image-data acquisition system includes a tunnel client, and the interactive control server system includes a active connection to enable the interactive control server system and the image-data acquisition system to transmit and receive communications through the firewall. A set of rules and the operational specifications of the image-data acquisition system, operable on the interactive control server system, determine how the data from the image-data acquisition system is provided to the interactive control server system. Conflicts between the data received from the image-data acquisition system and the data requested by the user are resolved by a set of prioritizing rules to determine the data transmitted to the user.

Claims

1. An interactive control server system coupled to a communications network for receiving first image data from a remote device and transmitting second image data that corresponds to the first image data to a user device over the communications network, the interactive control server system comprising:

a web application server to receive, from the user device, instructions for operating the remote device;

a device server to receive an identifier message from the remote device;

a tunnel server to establish, based on the identifier message, a communication tunnel with the remote device through a firewall associated with the remote device, the tunnel server configured to transmit the instructions to the remote device via the communication tunnel, the tunnel server configured to receive at least a portion of the first image data from the remote device through the communication tunnel based on the instructions;

a memory to store the at least a portion of the first image data received from the remote device through the communication tunnel; and

a video server to format the at least a portion of the first image data stored in the memory into the second image data and to transmit the second image data to the user device over the communications network.

2. The interactive control server system of claim 1, wherein the instructions comprise at least one or more commands to control the remote device, the first image data to be received, and format of the second image data to be transmitted to the user device.

3. The interactive control server system of claim 2, further comprising:

a specification table to convert the instructions to operational instructions specific to the remote device, wherein the tunnel server is operable to convert the operational instructions to a data format suitable for transmission through the communication tunnel to the remote device through the firewall.

4. The interactive control server system of claim 1, further comprising:

a set of rules to determine how the first image data is received by the interactive control server system.

5. The interactive control server system of claim 4, wherein conflicts between the first image data received from the remote device and the second image data transmitted to the user device are resolved by the rules to determine how the second image data is transmitted to the user device.

6. The interactive control server system of claim 1, wherein the firewall prevents any data from being transmitted from the user device to the remote device other than the instructions sent from the interactive control server system through the communication tunnel.

7. The interactive control server system of claim 1, wherein the tunnel server terminates the communication tunnel if the identifier message does not match an approved identifier message stored on the interactive control server system.

8. The interactive control server system of claim 1, wherein the device server, the tunnel server, the memory, and the video server are incorporated into a single housing.

9. The interactive control server system of claim 1, wherein the communication tunnel is established between the interactive control server system and the remote device in response to a request from the user device.

10. The interactive control server system of claim 1, wherein the communication tunnel remains open if an identifier received, through the communication tunnel, from the remote device matches the identifier message.

11. The interactive control server system of claim 1, wherein the at least a portion of the first image data is received through the communication tunnel and stored in the memory only in response to the instructions transmitted to the remote device.

12. The interactive control server system of claim 1, wherein the at least a portion of the first image data is received through the communication tunnel, stored in the memory, and formatted into the second image data only in response to the instructions transmitted to the remote device.

13. The interactive control server system of claim 1, wherein the tunnel server establishes the communication tunnel with the remote device only in response to the instructions transmitted to the remote device.

14. A method of receiving, at an interactive control server system coupled to a communications network, first image data from a remote device and transmitting second image data to a user device, the method comprising:

receiving instructions for operating the remote device from the user device;

receiving an identifier message from the remote device;

establishing, based on the identifier message, a communication tunnel with the remote device through a firewall associated with the remote device;

transmitting the instructions to the remote device via the communication tunnel;

receiving at least a portion of the first image data from the remote device through the communication tunnel based on the transmitted instructions;

storing in a memory the at least a portion of the first image data received from the remote device through the communication tunnel;

formatting the at least a portion of the first image data stored in the memory into the second image data; and

transmitting the second image data to the user device over the communications network.

15. The method of claim 14, wherein the instructions comprise at least one or more commands to control the remote device, the first image data to be received from the remote device, and the second image data to be transmitted to the user device.

16. The method of claim 15, further comprising:

storing a specification table for converting the instructions to operational instructions specific to the remote device, wherein a tunnel server of the interactive control server system is operable to convert the operational instructions to a data format suitable for transmission through the communication tunnel to the remote device through the firewall.

17. The method of claim 14, further comprising:

providing a set of rules for determining how the first image data is received at the interactive control server system.

18. The method of claim 17, further comprising:

resolving conflicts between the first image data received from the remote device and the second image data transmitted to the user device based on the rules to determine how the second image data is transmitted to the user device.

19. The method of claim 14, further comprising:

closing the communication tunnel if the identifier message does not match an approved identifier message stored on the interactive control server system.

20. The method of claim 14, wherein establishing, based on the identifier message, a communication tunnel with the remote device through a firewall associated with the remote device comprises:

receiving, through the communication tunnel, a query from the remote device to determine whether the communication tunnel is open for transmitting the instructions to the remote device;

sending, through the communication tunnel, an acknowledgement to the remote device that the communication tunnel is open;

receiving, through the communication tunnel, an identifier from the remote device; and

sending, through the communication tunnel, an acknowledgement to the remote device that the remote device is approved to receive the instructions if the identifier matches the identifier message.

21. An image-data acquisition system coupled to a communications network for providing first image data to an interactive control server system to be accessed by a user device for acquiring second image data corresponding to the first image data, the image-data acquisition system comprising, comprising:

a unique identifying information associated with the image-data acquisition system;
