    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 transmit times of frames from the electronic devices and receive times when the frames were received. For example, the current time offsets may be calculated using wireless ranging by ignoring distances between the A/V hub and the electronic devices. 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. Furthermore, the playback times of the electronic devices may have a temporal relationship so that the playback of the audio content by the electronic devices is coordinated.

    Abstract: An electronic device that performs automatic room filling is described. Based at least in part on information about an environment, which may include a second electronic device, the electronic device may determine a number of individuals in the environment. Then, based at least in part on the determined number of individuals, the electronic device may calculate an acoustic radiation pattern. For example, a width of a beam in the acoustic radiation pattern may be narrower when there is one individual in the environment, and the width of the beam may be wider when there is more than one individual in the environment. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.

    Abstract: An electronic device that performs automatic de-baffling is described. Based at least in part on information corresponding to a boundary of an environment (which may be acquired by a sensor, such as a microphone or an image sensor), the electronic device may determine a location of the boundary, which is proximate to the electronic device. Then, based at least in part on the location, the electronic device may calculate a modified acoustic radiation pattern of the electronic device, where a superposition of the modification acoustic radiation pattern and acoustic reflections from the boundary approximately matches a target acoustic radiation pattern of the electronic device. Next, using the modified acoustic radiation pattern, the electronic device may output sound corresponding to audio content from a set of drivers.

    Abstract: An electronic device that reduces relative drift is described. In particular, an interface circuit in the electronic device 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 a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may store the adjustments to the clock circuit. Furthermore, when a wireless reset occurs, the interface circuit may adapt the clock circuit based on the stored adjustments to reduce the relative drift while the interface circuit restores frequency lock with the second clock based on additional packets with additional transmit times that are received from the second electronic device.

    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 received from an audio/video (A/V) hub that communicates with the entertainment device) and one or more related states of the entertainment device, the portable electronic device may generate 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 portable electronic displays the user interface on the touch-sensitive display. In this way, the portable electronic device dynamically adapts the user interface.

    Abstract: In response to identifying a type of change in audio/video (A/V) content that was received from a content source, an A/V hub may generate display instructions specifying a display layout of the A/V content on a display in an A/V display device, and may provide the display instructions and the A/V content to the display to dynamically modify the display of the A/V content. For example, the A/V hub may display the A/V content in a central window of the display. This may involve swapping the A/V content with other A/V content that was previously displayed in the central window, and the other A/V content may be displayed in a tiled window (which may be smaller than the central window and may be located proximate to a periphery of the display). Alternatively, the A/V hub may display the A/V content in a new tiled window of the display.
