Abstract: 本申请实施例提供了一种电子设备的投屏方法和电子设备，该方法包括：接收电子设备播放视频操作，获取电子设备的状态标识，状态标识用于指示电子设备是否处于系统镜像投屏的状态；通过状态标识确定电子设备未处于系统镜像投屏的状态；接收用户投屏操作，获取投屏设备的第一设备信息；根据第一设备信息，电子设备通过DLNA投屏的方式投屏至投屏设备。该方法中在电子设备播放视频时，若电子设备未处于系统镜像投屏的状态，可以接收用户开启系统镜像投屏功能的操作，直接采用DLNA投屏的方式投屏至投屏设备，以减少画面黑边、卡顿、花屏及音画不同步等问题，所播放的视频画面清晰流畅，有效提升投屏效果，无需用户进行其他操作，提高用户的观看体验度。

Abstract: The present disclosure relates generally to media streaming, and in particular to devices (1, 2,3) and methods (4, 5) effecting a collaborative delivery of correlated media streams. Inter alia, a synchronizing node (1) is provided, comprising a processor (11) being configured to: establish (41) a synchronization of one or more source nodes (2) with respect to the synchronizing node (1) based on a heartbeat; receive (42) one or more packets from a number of the one or more source nodes (2) in accordance with the established synchronization; process (43) the one or more received packets in dependence of a compliance with the heartbeat; and maintain (44) the compliance with the heartbeat. This provides a collaborative delivery scheme enabling correlated media streams/packets to be delivered and to arrive at their destination "together" to meet the application requirement, without relying on global clock synchronization of all nodes and with minimum delay.

Abstract: A first screen device establishes a pairing session between a first screen device and a second screen device. The first screen device presents, in a user interface on the first screen device, a video and one or more media features related to the video. The media features pertain to at least one of a presentation of the video or user feedback about the video. The video is cast from the first screen device onto the second screen device. The first screen device receives, via the user interface, user input indicating a user request to enable presentation of at least one of the media features on the second screen device in connection with the video. In response to the user input, the first screen device causes the at least one of the media features to be presented on the second screen device in connection with the video.

Abstract: A method performed by an electronic device includes forming a playback group of devices that can participate in a shared playback of the same digital content. A time to play the digital content selection on multiple user devices is scheduled. One or more notifications to the multiple user devices are sent. One notification may include the schedule to play the content selection. While playing the content selection, a level of satisfaction from the multiple user devices is collected and recorded. One or more content recommendations to the multiple user devices is sent. The content recommendations are based on the recorded content selection level of satisfaction indications.

Abstract: An example first playback device is configured to: while the first playback device is in a synchrony group with a second playback device, play back a first version of audio content in synchrony with the second playback device; in response to identifying that a quality of a connection between the second playback device and a network device is below a threshold criterion, cause the second playback device to play back a second version of the audio content in synchrony with the first version of the audio content playing back by the first playback device; and in response to detecting a change in the quality of the connection between the second playback device and the network device such that the quality of the connection meets the threshold criterion, cause the second playback device to play back the first version of the audio content in synchrony with the first playback device.
