Abstract

A proxy streaming module executes on a first computing machine to stream multimedia data from a virtual channel that is established between the first computing machine and a second computing machine. In some instances, the multimedia data is generated by a multimedia device that communicates with the second computing machine. The proxy streaming module forwards the multimedia data to a presentation application that is executing on the first computing machine. A remoting application that executes on the first computing machine then captures the application output generated by the presentation application while the presentation application presents the multimedia data. The remoting application then transmits the application output to the second computing machine which displays the application output in an application output window.

Claims

1. A method for displaying on a local computing device, by an application executing on a remote computing device, multimedia data generated by a multimedia device connected to the local computing device, the remote computing device in communication with the local computing device via a virtual channel, the method comprising:

streaming, by a local computing device, multimedia data to a remote computing device via a virtual channel, the multimedia data generated by a multimedia device associated with the local computing device and comprising input to a presentation application executing on the remote computing device;

receiving, from the remote computing device, application output generated by the presentation application responsive to the transmitted multimedia data, the received application output including the multimedia data generated by the multimedia device and a second stream of multimedia data generated by a third computing device.

2. The method of claim 1, wherein streaming further comprises streaming the multimedia data responsive to receiving a request to execute the presentation application from a user of the local computing device.

3. The method of claim 1, wherein streaming further comprises transmitting, by a local streaming module executing on the local computing device, the multimedia data to the remote computing device via the virtual channel.

4. The method of claim 3, further comprising:

streaming, by a local streaming module executing on the local computing device, the multimedia data from a multimedia device interface; and

streaming, by the local streaming module executing on the local computing device, the multimedia data to a local remoting application executing on the local computing device.

5. The method of claim 1, further comprising encoding, by an encoder executing on the local computing device, the multimedia data before transmitting the multimedia data to the remote computing device.

6. The method of claim 1, further comprising constructing a packet, by a local remoting application on the local computing device, to include the multimedia data in a protocol wrapper before transmitting the packet comprising the multimedia data to the remote computing device.

7. The method of claim 1, further comprising encrypting, by an encoder executing on the local computing device, the multimedia data before transmitting the multimedia data to the remote computing device.

8. A local computing device for use in a system in which multimedia data generated by a multimedia device connected to the local computing device is displayed on the local computing device by an application executing on a remote computing device, the local computing device comprising:

a multimedia interface acquiring multimedia data from a multimedia device associated with the local computing device, the multimedia data comprising input to a presentation application executing on a remote computing device;

a streaming module transmitting the acquired multimedia data to the remote computing device via a virtual channel;

a local agent receiving, from the remote computing device, application output generated by the presentation application responsive to the transmitted multimedia data, the received application output including the multimedia data generated by the multimedia device and a second stream of multimedia data generated by a third computing device.

9. The local computing device of claim 8, wherein the streaming module streams the multimedia data responsive to receiving a request from a user of the local computing device to execute the presentation application.

10. The system of claim 8, wherein the streaming module executes on the local computing device and streams the multimedia data directly from the multimedia interface.

11. The system of claim 8, further comprising an encoder executing on the local computing device encoding the acquired multimedia data before transmission to the remote computing device.

12. The system of claim 8, further comprising a packet engine executing on the local computing device and constructing a packet including the acquired multimedia data in a protocol wrapper before transmitting the packet comprising the multimedia data to the remote computing device.

13. A local computing device for use in a system in which multimedia data generated by a multimedia device connected to the local computing device is displayed on the local computing device by an application executing on a remote computing device, the local computing device comprising:

means for streaming, by a local computing device, multimedia data to a remote computing device via a virtual channel, the multimedia data generated by a multimedia device associated with the local computing device and comprising input to a presentation application executing on the remote computing device;

means for receiving, from the remote computing device, application output generated by the presentation application responsive to the transmitted multimedia data, the received application output including the multimedia data generated by the multimedia device and a second stream of multimedia data generated by a third computing device.
