Abstract

A method for establishing a video communication using a communication device includes sending local audio signals to the remote communication device, receiving response audio signals from the remote communication device. The method further includes controlling the local UPnP set-top box to send local video signals to the remote UPnP set-top box according to the IP address of the remote UPnP set-top box, controlling the local UPnP set-top box to receive response video signals from the remote UPnP set-top box.

Claims

1. A communication device, the communication device in communication with a remote communication device and a local universal plug and play (UPnP) set-top box, the remote communication device in communication with a remote UPnP set-top box, the communication device comprising:

a storage device;

at least one processor; and

one or more programs stored in the storage device and being executable by the at least one processor, the one or more programs comprising a local digital media controller (DMC) module and a local session initiation protocol (SIP) module;

the local DMC module being operable to obtain an Internet Protocol (IP) address of the local UPnP set-top box;

the local SIP module being operable to send the IP address of the local UPnP set-top box and a request for obtaining an IP address of the remote UPnP set-top box to the remote communication device, and receive the IP address of the remote UPnP set-top box from the remote communication device;

the local DMC module being further operable to send the IP address of the remote UPnP set-top box to the local UPnP set-top box;

the local SIP module being further operable to send local audio signals to the remote communication device, and receive response audio signals from the remote communication device; and

the local DMC module being further operable to control the local UPnP set-top box to send local video signals to the remote UPnP set-top box according to the IP address of the remote UPnP set-top box, and control the local UPnP set-top box to receive response video signals from the remote UPnP set-top box.

2. The communication device of claim 1, wherein the local DMC module is further operable to search a network for the local UPnP set-top box according to a simple service discovery protocol.

3. The communication device of claim 1, wherein the SIP module sends the local audio signals to the remote communication device according to a session initiation protocol.

4. The communication device of claim 1, wherein the local DMC module sends the IP address of the remote UPnP set-top box to a digital media renderer (DMR) of the local UPnP set-top box according to a “

SetURI”

instruction of a UPnP audio and video (AV) Architecture.

5. The communication device of claim 4, wherein the local DMC module controls the DMR to send the local video signals to the remote UPnP set-top box according to a real time streaming protocol by sending a “

record”

instruction of the UPnP AV Architecture to the DMR, and controls a digital media server (DMS) to receive the response video signals from the remote UPnP set-top box according to the real time streaming protocol.

6. A method for establishing a video communication using a communication device, the method comprising:

obtaining an Internet Protocol (IP) address of the local UPnP set-top box from the network;

sending the IP address of the local UPnP set-top box and a request for obtaining an IP address of a remote UPnP set-top box to a remote communication device;

receiving the IP address of the remote UPnP set-top box from the remote communication device;

sending the IP address of the remote UPnP set-top box to the local UPnP set-top box;

sending local audio signals to the remote communication device;

receiving response audio signals from the remote communication device;

controlling the local UPnP set-top box to send local video signals to the remote UPnP set-top box according to the IP address of the remote UPnP set-top box; and

controlling the local UPnP set-top box to receive response video signals from the remote UPnP set-top box.

7. The method of claim 6, wherein the step of searching a network for the local UPnP set-top box according to a simple service discovery protocol.

8. The method of claim 6, wherein the step of sending audio signals to the remote communication device according to a session initiation protocol.

9. The method of claim 6, wherein the step of sending the IP address of the remote UPnP set-top box to a digital media renderer (DMR) of the local UPnP set-top box according to a “

SetURI”

instruction of a UPnP audio and video (AV) Architecture.

10. The method of claim 9, wherein the step of controlling the DMR to send the local video signals to the remote UPnP set-top box according to a real time streaming protocol by sending a “

record”

instruction of the UPnP AV Architecture to the DMR, and controlling a digital media server (DMS) to receive the response video signals from the remote UPnP set-top box according to the real time streaming protocol.

11. A storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform a method for establishing a video communication using a communication device, the method comprising:

obtaining an Internet Protocol (IP) address of the local UPnP set-top box from the network;

sending the IP address of the local UPnP set-top box and a request for obtaining an IP address of a remote UPnP set-top box to a remote communication device;

receiving the IP address of the remote UPnP set-top box from the remote communication device;

sending the IP address of the remote UPnP set-top box to the local UPnP set-top box;

sending local audio signals to the remote communication device;

receiving response audio signals from the remote communication device;

controlling the local UPnP set-top box to send local video signals to the remote UPnP set-top box according to the IP address of the remote UPnP set-top box; and

controlling the local UPnP set-top box to receive response video signals from the remote UPnP set-top box.

12. The medium of claim 11, wherein the step of searching a network for the local UPnP set-top box according to a simple service discovery protocol.

13. The medium of claim 11, wherein the step of sending audio signals to the remote communication device according to a session initiation protocol.

14. The medium of claim 11, wherein the step of sending the IP address of the remote UPnP set-top box to a digital media renderer (DMR) of the local UPnP set-top box according to a “

SetURI”

instruction of a UPnP audio and video (AV) Architecture.

15. The method of claim 14, wherein the step of controlling the DMR to send the local video signals to the remote UPnP set-top box according to a real time streaming protocol by sending a “

record”

instruction of the UPnP AV Architecture to the DMR, and controlling a digital media server (DMS) to receive the response video signals from the remote UPnP set-top box according to the real time streaming protocol.
