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: 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: 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.

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: An electronic device that coordinates a playback operation 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 determine a remaining time offset between the clock and the second clock. Next, the interface circuit may modify a future time when the second electronic device is to perform the playback operation based on the remaining time offset to determine a corrected future time, and may transmit information to the second electronic device specifying 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.

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 includes a state-detection circuit coupled to at least one pin in a high-definition multimedia-interface input connector, which can electrically couple to an entertainment device. When electrically coupled to the entertainment device, the state-detection circuit establishes a ground loop between the electronic device and the entertainment device. A control circuit in the A/V hub detects whether there is electrical coupling with the entertainment device using the state-detection circuit. When the electrical coupling is detected, the control circuit provides a set of first control commands associated with different types of entertainment devices until, in response, content activity is detected via the input connector. Moreover, when the content activity is detected, the control circuit provides a set of second control commands associated with different providers of entertainment devices until a change in a state of the entertainment device is detected via the input connector and the state-detection circuit.
