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 proxy streaming module executing on a remote computing device, multimedia data received from a local computing device via a virtual channel, the multimedia data generated by a multimedia device associated with the local computing device;

forwarding, by the proxy streaming module, the multimedia data to a presentation application executing on the remote computing device, the presentation application generating multimedia application output;

capturing, by a remoting application executing on the remote computing device, the generated multimedia application output; and

transmitting, by the remoting application executing on the remote computing device, the generated multimedia application output to the local computing device for display in an application output window on the local 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 5, further comprising decoding, by a decoder executing on the remote computing device, the multimedia data before forwarding the multimedia data to the presentation application.

7. 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.

8. The method of claim 7, further comprising deconstructing the packet, by the remoting application executing on the remote computing device, to extract the multimedia data from the packet before forwarding the multimedia data to the presentation application.

9. 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.

10. The method of claim 1, further comprising decrypting, by a decoder executing on the remote computing device, the multimedia data received from the local computing device.

11. The method of claim 1, further comprising storing, by the presentation application, the multimedia data in a storage repository.

12. A system 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 system comprising:

a local computing device;

a multimedia device communicating with the local computing device, the multimedia device generating multimedia data;

a remote computing device hosting the execution of a proxy streaming module to stream multimedia data received from the local computing device via a virtual channel and forwarding the multimedia data to a presentation application executing on the remote computing device;

wherein the presentation application generates multimedia application output and the remoting application captures the generated multimedia application output and transmits the multimedia application output to the local computing device for displaying in an application output window of the local computing device.

13. The system of claim 12, wherein the proxy streaming module streams the multimedia data responsive to receiving a request from a user of the local computing device to execute the presentation application.

14. The system of claim 12, further comprising a local remoting application executing on the local computing device transmitting the multimedia data to the remote computing device over the virtual channel.

15. The system of claim 14, further comprising a streaming module executing on the local computing device streaming the multimedia data from a multimedia interface to the remoting application executing on the local computing device.

16. The system of claim 12, further comprising an encoder executing on the local computing device encoding the multimedia data before transmitting the multimedia data to the remote computing device.

17. The system of claim 16, further comprising a decoder executing on the remote computing device to decode the multimedia data before forwarding the multimedia data to the presentation application.

18. The system of claim 14, wherein the local remoting application executing on the local computing device constructs a packet to include the multimedia data in a protocol wrapper before transmitting the packet comprising the multimedia data to the remote computing device.

19. The system of claim 17, wherein the remoting application executing on the remote computing device deconstructs the packet by extracting the multimedia data from the packet before forwarding the multimedia data to the presentation application.

20. The system of claim 12, wherein the presentation application stores the multimedia data in a storage repository.

20-1. A method for displaying on a client device, by an application executing on a remote server, multimedia data generated by a multimedia device connected to the client device, the method comprising:

transforming, by one or more filters of the client device, multimedia data to conform to a protocol of a virtual channel established between the client device and a remote server;

forwarding, by a streaming module executing on the client device, compressed multimedia data to the remote server via the virtual channel;

streaming, by a proxy streaming module executing on the remote server, multimedia data received from the client device via the virtual channel;

forwarding, by the proxy streaming module, multimedia data to a presentation application executing on the remote server;

capturing, by a remoting application executing on the remote server, application output generated by the presentation application during presentation of the multimedia data; and

transmitting, by the remoting application executing on the remote computing device, the application output to the local computing device; and

displaying, by the client device the application output in an application output window.
