Publication number: 20240135802Abstract: An electronic device that obtains a set of remote-control commands is described. During operation, the electronic device may receive an image associated with a second electronic device, where a brand and a model of the second electronic device are initially unknown to the electronic device. Then, the electronic device may perform image analysis on the image to determine at least the brand of the second electronic device. Moreover, the electronic device may access, based at least in part on the determined brand, the set of remote-control commands that are associated with the second electronic device. Next, the electronic device may store the set of remote-control commands in memory. Subsequently, when the electronic device receives user-interface activity information associated with a portable electronic device that specifies selection of the second electronic device, the electronic device may provide the set of remote-control commands to the second electronic device.Type: ApplicationFiled: June 1, 2023Publication date: April 25, 2024Inventor: Gaylord Yu

Patent number: 11729644Abstract: 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.Type: GrantFiled: April 2, 2022Date of Patent: August 15, 2023Assignee: B&W Group Ltd.Inventor: Gaylord Yu

Patent number: 11194542Abstract: 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.Type: GrantFiled: May 6, 2020Date of Patent: December 7, 2021Assignee: B&W Group Ltd.Inventors: Gaylord Yu, Steven Stupp

Patent number: 11042349Abstract: 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.Type: GrantFiled: April 8, 2019Date of Patent: June 22, 2021Assignee: B&W Group Ltd.Inventors: Leo Lay, Adrian Harold Chadd, Haisong Wang, Shiwei Zhao, Li Li, Gaylord Yu

Publication number: 20210132899Abstract: An electronic device may exchange packets with a second electronic device. These packets may include transmit times, based on a given clock in a given electronic device when the packets were transmitted. Moreover, when the packets are received by the electronic device, the electronic device may store associated receive times based on a clock in the electronic device. Using minimum time differences between the transmit and receive times, the electronic device may calculate a time offset between the electronic device and the second electronic device, which may then be used to determine future times in a clock domain of the second electronic device. Moreover, the electronic device may provide additional packets to the second electronic device, where a given additional packet includes audio data, and a playback time, corresponding to a given future time, when the audio data is to be played back by the second electronic device.Type: ApplicationFiled: January 11, 2021Publication date: May 6, 2021Inventors: Leo Lay, Gaylord Yu, David Bryant, Vanshil Shah

Patent number: 10956114Abstract: An audio/video (A/V) hub that selectively determines one or more acoustic characteristics of an environment that includes the A/V hub is described. In particular, the A/V hub may detect, using wireless communication, an electronic device (such as a speaker) in the environment. Then, the A/V hub may determine a change condition, such as when the electronic device was not previously detected in the environment and/or a change in a location of the electronic device. In response to determining the change condition, the A/V hub may transition into a characterization mode. During the characterization mode, the A/V hub may: provide instructions to the electronic device to playback audio content at a specified playback time; determine one or more acoustic characteristics of the environment based on acoustic measurements in the environment; and store the one or more acoustic characteristics and/or a location of the electronic device in memory.Type: GrantFiled: October 22, 2017Date of Patent: March 23, 2021Assignee: B&W Group Ltd.Inventors: Gaylord Yu, Steven Stupp

Patent number: 10684817Abstract: 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).

Patent number: 10649722Abstract: 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.
