    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 may measure the sound, corresponding to audio content, output by electronic devices. Then, the A/V hub may compare the measured sound to a desired acoustic characteristic at a first location in the environment based on the first location, a second location of the A/V hub, and an acoustic transfer function of the environment in at least a band of frequencies. For example, the comparison may involve calculating the acoustic transfer function at the first location based on the acoustic transfer function at other locations in the environment and correcting the measured sound based on the calculated the acoustic transfer function at the first location. Moreover, the A/V hub may determine equalized audio content based on the comparison and the audio content.

    Abstract: A portable electronic device with a touch-sensitive display (such as a cellular telephone) provides a wireless remote control for an entertainment device (such as a consumer-electronic device). Based on device-state information that specifies a current state of the entertainment device (which is determined by an audio/video (A/V) hub that communicates with the entertainment device) and one or more related states of the entertainment device, the A/V hub may generate user-interface information that specifies a user interface that includes one or more virtual command icons. Note that the one or more related states are related to the current state in a state diagram by corresponding operations that transition the entertainment device from the current state to the one or more related states. Then, the A/V hub provides the user interface to the portable electronic device. In this way, the A/V hub device dynamically adapts the user interface.

    Abstract: A processor in an electronic device may coordinate an interface clock in the electronic device with a second interface clock in a second electronic device based on time-coordination information received in packets from the second electronic device. Then, the processor captures timing information associated with the interface clock provided by an interface clock circuit to increase a resolution of a system clock. Moreover, the processor may track, using the timing information, relative drift as a function of time between the system clock and the interface clock, and may determine, based on the relative drift, an estimated time offset between the interface clock and the system clock at the future time. Next, the processor modifies a future time when the electronic device is to perform the playback operation based on the estimated time offset to determine a corrected future time, and may perform the playback operation at the corrected future time.

    Abstract: A processor in an electronic device maintains coordination between a system clock provided by a system clock circuit and an interface clock provided by a clock circuit. Then, the processor may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between the interface clock and a second interface clock in the second electronic device. Moreover, the processor adjusts, based on the relative drift, the system clock circuit to eliminate the relative drift. Next, the processor may determine a remaining time offset between the interface clock and the second interface clock. Furthermore, the processor modifies a future time when the electronic device is to perform the playback operation based on the remaining time offset to determine a corrected future time, and may perform the playback operation at the corrected future time.

    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.
