Abstract

An apparatus and method are provided for exchanging data between Universal Plug and Play (UPnP) based devices. The apparatus includes a controller that generates and transmits a request for a parameter to a controlled device, and receives a response to the request from the controlled device; and a fast event data bus module that establishes a fast event data transmission path, based on information included in the response, and receives fast event data.

Claims

1. An apparatus for exchanging data between Universal Plug and Play (UPnP) based devices, the apparatus comprising:

a controller that generates and transmits a request for a parameter to a controlled device, and receives a response to the request from the controlled device; and

a fast event data bus module that establishes a fast event data transmission path, based on information included in the response, and receives fast event data.

2. The apparatus of claim 1, wherein the request for the parameter comprises:

a parameter name;

a parameter reception period type;

a parameter reception period;

a parameter reception duration type; and

a parameter reception duration.

3. The apparatus of claim 2, wherein the response to the request comprises:

an IDentifier (ID) for distinguishing parameters;

a parameter transmission period;

a parameter transmission duration; and

a parameter transmission address.

4. The apparatus of claim 2, wherein the request for the parameter further comprises a parameter reception address.

5. The apparatus of claim 4, wherein the response to the request comprises:

an IDentifier (ID) for distinguishing parameters;

a parameter transmission period; and

a parameter transmission duration.

6. The apparatus of claim 1, wherein the fast event data comprises:

a Query IDentifier (ID) for distinguishing parameters; and

a data value corresponding to a corresponding parameter.

7. The apparatus of claim 1, wherein the fast event data comprises a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the fast event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.

8. An apparatus for exchanging data between Universal Plug and Play (UPnP) based devices, the apparatus comprising:

a controlled unit that receives a request for a parameter from a control point, and transmits a response to the request to the control point; and

a fast event data bus module that establishes a fast event data transmission path with the control point, and transmits fast event data.

9. The apparatus of claim 8, wherein the request for the parameter comprises:

a parameter name;

a parameter reception period type;

a parameter reception period;

a parameter reception duration type; and

a parameter reception duration.

10. The apparatus of claim 9, wherein the response to the request comprises:

an IDentifier (ID) for distinguishing parameters;

a parameter transmission period;

a parameter transmission duration; and

a parameter transmission address.

11. The apparatus of claim 9, wherein the request for the parameter further comprises a parameter reception address.

12. The apparatus of claim 11, wherein response to the request comprises:

an IDentifier (ID) for distinguishing parameters;

a parameter transmission period; and

a parameter transmission duration.

13. The apparatus of claim 8, wherein the fast event data comprises:

a Query IDentifier (ID) for distinguishing parameters; and

a data value corresponding to a corresponding parameter.

14. The apparatus of claim 8, wherein the fast event data comprises a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the fast event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.

15. A method of exchanging data between Universal Plug and Play (UPnP) based devices, the method comprising:

generating, by a control point, a request for a parameter;

transmitting the request to a controlled device;

receiving a response to the request from the controlled device;

establishing a fast event data transmission path using information included in the response; and

receiving fast event data through the fast event data transmission path.

16. The method of claim 15, further comprising:

receiving, by the controlled device, the request for the parameter from the control point;

generating the response to the requesting;

transmitting the response to the control point;

establishing the fast event data transmission path with the control point; and

transmitting the fast event data to the control point through the fast event data transmission path.

17. The method of claim 15, wherein the request for the parameter includes a parameter name, a parameter reception period type, a parameter reception period, a parameter reception duration type, and a parameter reception duration.

18. The method of claim 15, wherein the response to the request includes an IDentifier (ID) for distinguishing parameters, a parameter transmission period, a parameter transmission duration, and a parameter transmission address.

19. The method of claim 15, wherein the fast event data includes a Query IDentifier for distinguishing parameters and a data value corresponding to a corresponding parameter.

20. The method of claim 15, wherein the fast event data includes a type of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) packet based on an Internet Protocol (IP), and

wherein the fast event data is included in one of a binary value or an eXtensible Markup Language (XML) value within the TCP or the UDP packet.
