Patent number: 11678163Abstract: A power-efficient, balanced, and reliable true wireless Bluetooth stereo audio solution is provided. Two audio sink devices are used to render audio content received from an audio source. One sink device is connected to the audio source via a primary link. The other sink device sniffs communication on the primary link. The two sink devices are connected via a hybrid link. In some embodiments, a token is passed dynamically between the two sink devices. The sink device that has the token acts as a primary sink device on a primary link with the source. The other sink device acts as a slave to the primary link.Type: GrantFiled: March 1, 2021Date of Patent: June 13, 2023Assignee: Avago Technologies International Sales Pte.

Publication number: 20210258874Abstract: In some aspects, the disclosure is directed to methods and systems for providing a hybrid low power, high bandwidth media transport protocol between media sinks and media sources by splitting control and synchronization commands to a low power communication interface, and media data to a high bandwidth unidirectional communication interface. Media sinks need not transmit via the high bandwidth unidirectional communication interface, reducing power consumption, which may be particularly beneficial for small devices with limited battery capacity such as wireless earbuds.Type: ApplicationFiled: May 4, 2021Publication date: August 19, 2021Inventors: David Lee RECKER, Brandon B. BAE, Hea Joung KIM, Mark GONIKBERG, Shawn DING

Patent number: 10645735Abstract: In some aspects, the disclosure is directed to methods and systems for an enhanced data rate, low energy wireless communication. Devices may communicate over predetermined wireless bands such as the 2.4 GHz and 5 GHz ISM bands, using ?/4-differential quadrature phase shift keying, with physical layer rates of 1, 2, 4, 8 Mbps or higher. Symbol timing may be at any frequency, and may be 256 ns in some implementations. In some implementations, to extend device battery life, devices may use a low latency reconnect mechanism allowing frequent hibernation or shutdown of transmitters and/or carriers.Type: GrantFiled: March 14, 2018Date of Patent: May 5, 2020Assignee: Avago Technologies International Sales Pte.
