Abstract: An audio/video (A/V) hub provides feedback to a user of a portable electronic device with a touch-sensitive display (such as a cellular telephone) that is used as a wireless remote control for an audio/video (A/V) display device, the A/V hub and/or a consumer-electronic device. In particular, when the A/V hub receives, from the portable electronic device, user-interface activity information associated with a user interface displayed on a touch-sensitive display, the A/V hub generates visual feedback based on the user-interface activity information. Then, the A/V hub provides the visual feedback to the A/V display device for display on the A/V display device. The visual feedback indicates a position of at least a touch contact point of a user of the portable electronic device relative to a strike area of at least a virtual command icon in the user interface.

Abstract: In order to maintain performance during wireless communication, a transmitting electronic device may concurrently and independently communicate redundant information to a receiving electronic device. In particular, information associated with a data stream may be communicated to the receiving electronic device using one or more channels by two radios using one or more wireless local area network communication protocols. The packets transmitted by the radios may preferentially include the same information. Moreover, the transmitting electronic device may attempt to maintain the redundant communication if a performance metric associated with the one or more channels degrades. For example, the transmitting electronic device may transfer communication to a different channel or may compress the information in the packets in the one or more channels if the throughput drops below a threshold value. Furthermore, the concurrent communication may allow the transmitting electronic device determine link quality without disrupting the communication of the information.

Abstract: In order to maintain performance during wireless communication via a channel in a restricted band of frequencies, a transmitting electronic device may monitor for unknown wireless signals in the restricted band of frequencies. If unknown wireless signals are detected by a radio in the transmitting electronic device, the transmitting electronic device may transfer the communication to another channel (which may have poorer performance) in a band of frequencies outside of the restricted band of frequencies. Moreover, a separate radio in the transmitting electronic device may concurrently receive the unknown wireless signals in the channel and may analyze the unknown wireless signals based on a target signature. If the unknown wireless signals do not match the target signature, the transmitting electronic device may transfer the communication back to the channel to restore the performance.

Abstract: An audio/video (A/V) hub determines display instructions specifying information to be displayed on a display in an A/V display device that includes icons associated with content sources. Then, the A/V hub provides the display instructions to the A/V display device for display on the display. In response to receiving a user selection of a content source based on activation of a single command feature in a portable electronic device that is associated with the content source, the A/V hub provides a request for high-definition multimedia-interface (HDMI) content to the content source. When the A/V hub receives the HDMI content from the content source, the A/V hub provide the HDMI content and second display instructions to an A/V display device as frames with the HDMI content are received from the content source, so that the HDMI content is displayed in a tiled window on the display in the A/V display device.

Abstract: An audio/video (A/V) hub is described. This A/V hub determines display instructions specifying information to be displayed on a display in an A/V display device that includes icons associated with content sources. These content sources are located at arbitrary or different locations in a structure, including locations external to an environment of the A/V hub and the A/V display device. Then, the A/V hub provides the display instructions to the A/V display device for display on the display.

Abstract: An audio/video (A/V) hub that coordinates playback of audio content is described. In particular, the A/V hub may calculate current time offsets between clocks in electronic devices and a clock in the A/V hub based on differences between receive times when frames are received from electronic devices and expected transmit times of the frames. For example, the expected transmit times may be based on coordination of clocks in the electronic devices and a clock in the A/V hub at a previous time and a predefined transmit schedule of the frames. Then, the A/V hub may transmit, to the electronic devices, one or more frames that include audio content and playback timing information, which may specify playback times when the electronic devices are to playback the audio content based on the current time offsets.
