Patent number: 10993274Abstract: In some implementations a system can be configured to reduce the burden of pairing user devices with playback devices. For example, all users (or user devices) who commonly operate within a particular environment (e.g., a home) can be configured as authorized users of playback devices within the particular environment. When one of the authorized users pairs a user device with a playback device, all of the user devices for all authorized users can be automatically paired with the playback device as a result of the single pairing. Thus, only a single authorized user is burdened with the pairing process in order to pair all authorized users with the playback device.Type: GrantFiled: February 27, 2019Date of Patent: April 27, 2021Assignee: Apple Inc.Inventors: Deepak Iyer, Thomas Alsina, Edward T.
