Abstract

A remote-controlled media system is described in which a remote control communicates over a conventional wireless local area network (WLAN) with a remote server. The remote control and remote server configure a network connection over the WLAN for communicating with one another. The remote server receives a remote command from the remote control and associates the remote command with the remote control, an application, and an output device over which the application outputs media data files. The remote server determines a particular output function of the application that is represented by the remote command, and then accesses the application through a command interface of the application to thereby invoke the output feature at the application and the output device.

Claims

1. A remote control comprising:

a keypad including a plurality of buttons;

a button identifier that is operable to perform an identification of a selected button from among the plurality of buttons;

a network adaptor that is operable to generate a command packet that is compatible with a transmission protocol of a wireless network, based on the identification of the selected button; and

a transceiver that is operable to transmit the command packet over the wireless network for remote operation of a host computer.

2. The remote control of claim 1 wherein the network adaptor comprises a remote protocol component that broadcasts a presence of the remote control on the wireless network for detection by the host computer.

3. The remote control of claim 2 wherein the remote protocol component is operable to communicate with a host protocol component on the host computer, so as to configure a network connection with the host computer, using the transmission protocol.

4. The remote control of claim 1 wherein the network adaptor is operable to include a remote control identifier for inclusion in the command packet for identifying the remote control from among a plurality of remote controls.

5. The remote control of claim 1 wherein the transceiver is operable to transmit the command packet to a remote server for association of the command packet, and thereby the selected button, with an action of an application on the host computer that is operable to output media data files over the wireless network to an output device.

6. The remote control of claim 5 wherein the transceiver is operable to transmit the command packet to the remote server for invocation of the action of the application by the remote server.

7. The remote control of claim 1 wherein the network adaptor is operable to associate the command packet, and thereby the selected button, with an action of an application on the host computer that is operable to output media data files over the wireless network to an output device.

8. The remote control of claim 7 wherein the remote control comprises a user interface by which an association of the command packet, and thereby the selected button, with the action of the application may be configured by a user of the remote control.

9. The remote control of claim 1 wherein the transmission protocol includes one or more of the family of 802.11 wireless transmission protocols.

10. The remote control of claim 1 wherein the keypad includes the plurality of buttons as graphically-displayed buttons on a user touch screen.

11. The remote control of claim 1 wherein the command packet is operable to control an action of a streaming audio application on the host computer that transmits audio or video files over the wireless network to an output device.

12. A method comprising:

identifying a selected button from among a plurality of buttons on a remote control;

generating a command packet that is compatible with a transmission protocol of a wireless network, based on the identifying of the selected button; and

transmitting the command packet over the wireless network for remote operation of a host computer.

13. The method of claim 12 wherein generating the command packet includes broadcasting a presence of the remote control on the wireless network for detection by the host computer.

14. The method of claim 13 broadcasting the presence of the remote control on the wireless network comprises communicating with a host protocol component on the host computer, so as to configure a network connection with the host computer, using the transmission protocol.

15. The method of claim 12 wherein generating the command packet comprises including a remote control identifier for inclusion in the command packet for identifying the remote control from among a plurality of remote controls.

16. The method of claim 12 wherein transmitting the command packet over the wireless network comprises transmitting the command packet to a remote server for association of the command packet, and thereby the selected button, with an action of an application that is operable to output media data files over the wireless network to an output device.

17. The method of claim 16 wherein transmitting the command packet to the remote server comprises transmitting the command packet to the remote server for invocation of the action of the application by the remote server.

18. The method of claim 12 wherein generating the command packet comprises associating the command packet, and thereby the selected button, with an action of an application that is operable to output media data files over the wireless network to an output device.

19. The method of claim 18 wherein generating the command packet comprises receiving an association of the command packet, and thereby the selected button, with the action of the application by way of a user interface.

20. The method of claim 12 wherein generating the command packet comprises generating the command packet such that the transmission protocol is compatible with one or more of the family of 802.11 wireless transmission protocols.
