Abstract

A first User Terminal, UT, and a method performed by a first User Terminal, UT, for synchronizing playback of media streams is provided. The UT selects a media stream to be played synchronously by the first UT and at least one second UT. The first UT provides an indicator associated with the selected media stream and an indicator of the at least one second UT to a coordination server. The first UT requests the selected media stream from streaming storage and buffers the received data being associated with the selected media stream. The first UT then receives synchronization instructions from the coordination server and thereafter initiates playback of the media stream based on the received synchronization instructions, and thereby enabling the first UTs to, with respect to the at least one second UT, synchronously playback the media stream.
