Abstract
It is provided a method for synchronizing content playback at the presentation level, wherein, a first content is presented on a first device and a second content that is the same as or correlated with the first content is presented on a second device. The method comprises steps of receiving status messages from the first device and the second device, wherein the status messages comprise information about playback positions of the first content and the second content currently being playbacked at the presentation level of the first device and the second device; and in response to differences between playback positions of the first content and the second content comprised in the status messages being above a threshold value, performing adjustment to maintain difference of playback positions of the first content and the second content at the presentation level of the first device and the second device below the threshold value.
