Direct connection with side channel control
First Claim
1. A method of controlling presentation of audio-video content on a presentation device by a wireless computing device, the method comprising:
- discovering, via a device discovery process and/or a service discovery process executing on the wireless computing device, a plurality of presentation devices capable of presenting the audio-video content;
displaying representations of the plurality of presentation devices in a graphical user interface of the wireless computing device;
receiving an indication of a user selection of a presentation device of the plurality of 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, at least one different transmission parameter from that of the first communications channel, and a different radio of the wireless computing device from that used for 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 while a video portion of the audio-video content is being displayed in the graphical user interface of the wireless computing 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;
formatting a command for transmission to the indicated presentation device over the second communications channel; and
transmitting the command to the indicated presentation device over the second communications channel.

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.

9. A computer readable memory encoded with computer-executable instructions that, when executed, perform operations for the presentation of content by a presentation device, the operations comprising:
-
receiving, by the presentation device, a request for a device discovery response and/or a service 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 and at least one different transmission parameter 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 while a video portion of the audio-video content is being displayed in a graphical user interface of the wireless computing device; presenting the received audio-video content on the presentation device; receiving a command that is formatted by the wireless computing device, the command requesting a modification of a manner in which the streamed audio-video content is being presented on the indicated 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. - View Dependent Claims (10, 11, 12, 13, 14)

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 remotely presented, the operations including; discovering, via a device discovery process and/or a service discovery process executing on the wireless computing device, a plurality of 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 plurality of 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 while a video portion of the audio-video content is being displayed in a graphical user interface of the wireless computing 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; formatting a command for transmission to the user selected presentation device over the second communications channel; and transmitting the command to the user selected presentation device over the second communications channel. - View Dependent Claims (16, 17, 18, 19, 20)
