Synchronization between reproduction devices can thereby be established even when, in a state in which a content is being reproduced by one reproduction device, another reproduction device subsequently connects to the distribution device.

VLC-based video frame synchronization

A VLC signal representing an alignment identifier is detected by cameras (4) of multiple user devices (1, 2, 3) filming a scene. Encoded video frames (91, 92, 93) from the user devices (1, 2, 3) are decoded and light patterns representing the captured VLC signal are identified in at least some of the video frames following decoding. The light patterns are decoded into alignment identifiers that are used in order to time align video frames (91, 92, 93) from different user devices (1, 2, 3) to thereby achieve video frame synchronization of video data from multiple user devices (1, 2, 3) recording a scene. The embodiments thereby enable video frame synchronization without the need for accurate clock synchronization between the user devices (1, 2, 3) and a video synchronization system (10).
