Abstract: In a general aspect, a system for media playback can include a first media playback device configured to receive a media stream from a media casting device over a data network, the first media playback device being a member of the media playback group and a second media playback device configured to receive the media stream, the second media playback device being a member of the media playback group. The first media playback device and the second media playback device can be collectively configured to designate one of the first media playback device and the second media playback device as a leader playback device of the media playback group. The playback device not designated as the leader playback device can be designated as a follower playback device of the media playback group. The first media playback device and the second media playback device can be further collectively configured to determine a clock offset between the leader playback device and the follower playback device. The leader playback device can be configured to receive a broadcast of the media stream over the data network; play the media stream; and provide the media stream to the follower playback device. The follower playback device can be configured to play the media stream in synchronization with the leader playback device based on the clock offset.

Abstract: Systems, methods, and media for presenting media content are provided. In some implementations, a system for presenting media content is provided, the system comprising: a hardware processor that is programmed to: establish a connection with a media playback device; respond to a discovery request from a computing device presenting a media content item; establish a persistent communication channel with the computing device over a network in response to a request from the computing device to establish the persistent communication channel; receive identifying information of the media content item being presented by the computing device and identifying information of a source of the media content item being presented by the computing device; request the media content item from the identified source of the media content item as a stream of media content; and cause the media content item to be presented using the media playback device.
