Direct connection with side channel control
First Claim
1. A method of operating a wireless audio-video source device to provide audio-video content to a remote playback device, the method comprising:
- providing, by the wireless audio-video source device, a graphical user interface that enables control over presentation of audio-video content on the remote playback device;
receiving, by the wireless audio-video source device, an indication of a selection of a first presentation control of the graphical user interface, the selection of the first presentation control indicating that the audio-video content is to be presented by the remote playback device;
streaming, by the wireless audio-video source device, data representing the audio-video content to the remote playback device over a first channel for presentation of the audio-video content by the remote playback device based, at least in part, on the selection of the first presentation control;
negotiating, by the wireless audio-video source device, a side channel with the remote playback device, wherein the side channel is within a portion of a digital television spectrum and is negotiated without regard to whether one or more frequencies for the side channel is within an unused portion of the digital TV spectrum; and
transmitting, by the wireless audio-video source device, a command to the remote playback over a side channel to control presentation of the audio-video content on the remote playback device.

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.

10. At least one computer readable storage medium encoded with computer-executable instructions that, when executed, perform a method of operating a wireless audio-video source device that provides content for presentation on a remote audio-video presentation device, the method comprising:
-
negotiating a side channel with the remote playback device, wherein the side channel is negotiated to be within a portion of a digital television spectrum and is negotiated without regard to whether one or more frequencies for the side channel is within an unused portion of the digital TV spectrum; displaying a graphical user interface having controls for controlling playback of audio-video content on the remote audio-video presentation device; receiving an indication of a selection of a first presentation control of the graphical user interface, the selection of the first presentation control indicating that the audio-video content is to be presented by the remote audio-video presentation device; streaming data representing the audio-video content to the remote audio-video presentation device over a first channel, different from the side channel, for presentation of the audio-video content on the remote audio-video presentation device, based, at least in part, on the selection of the first presentation control; and over the side channel, transmitting to the remote audio-video presentation device a command for the remote audio-video presentation device to alter a presentation characteristic of the audio-video content, the transmitting comprising transmitting in the portion of the digital TV spectrum, wherein the at least one computer readable storage medium includes a random access memory, a read only memory, a flash memory, an EEPROM, an optical disk, a magnetic disk, a magnetic tape, and/or a magnetic cassette. - View Dependent Claims (11, 12, 13, 14, 15)

16. An audio-video presentation device adapted to display audio-video content provided by a computing device, the audio-video presentation device comprising:
-
an audio-video output component; at least one radio configured to communicate in both a first frequency band and in a second frequency band, the second frequency band comprising a digital TV band; a controller adapted to; direct data representing the audio-video content received over the first frequency band from the computing device to the audio-video output component for presentation; negotiate a side channel with the computing device, wherein the side channel is negotiated to be within a portion of the second frequency band and is negotiated without regard to whether one or more frequencies for the side channel is within an unused portion of the digital TV spectrum; and alter a characteristic of the audio-video content presented on the audio-video output component based on a command received from the computing device over the negotiated side channel such that the audio-video content is presented in only one portion of the audio-video output component while other audio-video content provided by at least one source other than the computing device is presented in other portions of the audio-video output component. - View Dependent Claims (17, 18, 19, 20)
