Abstract

A wireless computer that pairs with a remote audio-video presentation device, such as a television. As a result of the pairing, a communication channel is established for the computer to transmit audio-video content for presentation through that device. Additionally, as part of the pairing, the computer and remote device select a side channel for communication of user commands. The wireless computer may display a user interface through which a user may input commands that control the manner in which the remote audio-video device presents the content. As a result, a user may use the wireless computer as a remote control for the audio-video device, controlling both the content presented and the manner in which it is presented. The side channel may use different frequencies than the channel used to communicate audio-video content, and may use very low power at frequencies in the digital TV spectrum.

Claims

1. A method of controlling presentation of audio-video content on a presentation device by a wireless computing device, the method comprising:

discovering, via at least one of a device discovery process or a service discovery process executing on the wireless computing device, one or more presentation devices capable of presenting the audio-video content;

displaying at least one representation of the one or more presentation devices in a graphical user interface;

receiving an indication of a user selection of a presentation device from amongst the one or more presentation devices;

establishing a first communications channel with the indicated presentation device;

establishing a second communications channel with the indicated presentation device, the second communications channel employing a different protocol from that of the first communications channel, and at least one different transmission parameter from that of the first communications channel;

streaming the audio-video content from the wireless computing device to the indicated presentation device over the first communications channel for presentation on the indicated presentation device;

receiving a user request for modification of the presentation of the streamed audio-video content on the indicated presentation device, the user request representing a request to change at least one characteristic of the presentation of the streamed audio-video content on the indicated presentation device; and

transmitting a command representing the request to the indicated presentation device over the second communications channel.

2. The method of claim 1, wherein the method further comprises:

receiving the audio-video content via an Internet connected wireless network access point.

3. The method of claim 1, wherein the at least one characteristic of the presentation of the streamed audio-video content includes at least one of an audio characteristic or a video characteristic.

4. The method of claim 1, wherein communications protocols for the first communications channel and for the second communications channel are peer-to-peer communications protocols.

5. The method of claim 1, wherein establishing the second communications channel includes:

identifying a transport; and

configuring a driver and a radio of the wireless computing device based at least in part on the identified transport.

6. The method of claim 1, wherein the audio-video content includes a representation of at least a window of the graphical user interface.

7. The method of claim 1, wherein the first communication channel is a Wi-Fi Direct connection between the wireless computing device and the indicated presentation device, and wherein the wireless computing device is a Wi-Fi Direct group owner for the Wi-Fi Direct connection and the indicated presentation device is a Wi-Fi Direct client for the Wi-Fi Direct connection.

8. The method of claim 1, further comprising:

receiving the audio-video content over a different radio than that used by the wireless communications device for the first communications channel.

9. A method for presenting audio-video content, the method comprising:

receiving, by a presentation device, a request for a discovery response from a wireless computing device;

in response to the received request, transmitting an indication that the presentation device is capable of presenting the audio-video content;

in response to a user request received via the wireless computing device, establishing a first communications channel with the wireless computing device;

establishing a second communications channel with the wireless computing device, the second communications channel employing a different protocol from that of the first communications channel;

receiving the audio-video content in a stream from the wireless computing device over the first communications channel for presentation on the presentation device;

presenting the received audio-video content on the presentation device;

receiving a command, the command requesting a modification of a manner in which the streamed audio-video content is being presented on the presentation device; and

in response to the received command, modifying the manner in which the streamed audio-video content is being presented on the presentation device.

10. The method of claim 9, wherein modifying the manner in which the streamed audio-video content is being presented on the presentation device includes:

changing at least one audio or video characteristic of the presentation of the streamed audio-video content on the presentation device.

11. The method of claim 9, wherein communications protocols for the first communications channel and for the second communications channel are peer-to-peer communications protocols.

12. The method of claim 9, wherein the audio-video content includes a representation of at least a window of a graphical user interface of the wireless computing device.

15. A wireless computing device, comprising:

a wireless radio;

a processor; and

a memory, wherein the processor and the memory respectively store and execute instructions for causing the wireless computing device to perform operations that cause audio-video content to be presented, the operations including;

discovering, via a discovery process, a one or more presentation devices capable of presenting the audio-video content;

establishing a first communications channel over the radio with a user selected presentation device of the one or more presentation devices capable of presenting the audio-video content;

establishing a second communications channel with the user selected presentation device, the second communications channel employing at least one different transmission parameter from that employed for the first communications channel;

streaming the audio-video content from the wireless computing device to the user selected presentation device over the first communications channel for presentation on the user selected presentation device;

receiving a user request for modification of a manner in which the streamed audio-video content is being presented on the user selected presentation device; and

transmitting a command to the user selected presentation device over the second communications channel requesting a modification of the manner in which the streamed audio-video content is being presented on the user selected presentation device.

16. The wireless computing device of claim 15, further comprising:

another wireless radio, wherein the second communications channel is carried over the other radio, the first communications channel is a Wi-Fi Direct communications channel, and the second communications channel is a Bluetooth communications channel.

17. The wireless computing device of claim 15, wherein communications protocols for the first communications channel and for the second communications channel are peer-to-peer communications protocols.

18. The wireless computing device of claim 15, wherein the audio-video content includes a representation of at least a window of a graphical user interface of the wireless computing device.

19. The wireless computing device of claim 15, wherein the operations further include:
