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 translation: 在一般方面，用于媒体回放的系统可以包括被配置为通过数据网络从媒体投射设备接收媒体流的第一媒体回放设备，第一媒体回放设备是媒体播放组的成员，第二媒体 播放装置，被配置为接收媒体流，第二媒体回放设备是媒体播放组的成员。 第一媒体播放装置和第二媒体播放装置可以被共同配置为将第一媒体播放装置和第二媒体播放装置中的一个指定为媒体播放组的引导重放装置。 未被指定为领先播放装置的重放装置可被指定为媒体播放组的随动播放装置。 第一媒体播放设备和第二媒体播放设备可以进一步统一配置为确定领导者回放设备和跟随回放设备之间的时钟偏移。 领先播放设备可以被配置为通过数据网络接收媒体流的广播; 播放媒体流; 并将媒体流提供给跟随回放设备。 跟随回放设备可以被配置为基于时钟偏移与领先者回放设备同步地播放媒体流。
