    Abstract: An audio/video (A/V) hub that calculates an estimated location is described. In particular, the A/V hub may calculate an estimated location of a listener relative to electronic devices (such as electronic devices that include speakers) in an environment that includes the A/V hub and the electronic devices based on: communication with another electronic device; sound measurements in the environment; and/or time-of-flight measurements. 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 estimated location. Moreover, 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 audio/video (A/V) hub that aggregates electronic devices is described. In particular, the A/V hub may measure sound, corresponding to audio content, output by electronic devices (such as electronic devices that include speakers). Then, the A/V hub may aggregate the electronic devices into two or more subsets based on the measured sound. Moreover, the A/V hub may determine, for the subsets, playback timing information, which may specify playback times when the electronic devices in a given subset are to playback the audio content. Next, the A/V hub may transmit, to the electronic devices, one or more frames that include the audio content and playback timing information, where the playback times of the electronic devices in at least the given subset have a temporal relationship so that the playback of the audio content by the electronic devices in the given subset is coordinated.

    Abstract: An audio/video (A/V) hub that determines an environment of a portable electronic device is described. In particular, the A/V hub may identify the environment based on performance information about communication between the portable electronic device and receiver devices (which was received from the receiver devices), and a history of behavior of an individual associated with the portable electronic device and the A/V hub. Alternatively, the A/V hub may identify the environment based on performance information about communication between the portable electronic device and the A/V hub and the portable electronic device and another A/V hub (which was received from the portable electronic device and/or the other A/V hub), and a history of behavior of an individual associated with the portable electronic device and the A/V hub. Based on the determination, the A/V hub provides an instruction to power on an A/V display device in the environment.

    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: 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.
