Abstract

The invention relates to audio-video-synchronization, where light is captured from a light source. At least a timestamp is determined from the light. Audio stream is received from an audio source, and the audio stream is played from the point defined by the time stamp. The invention relates also to a method and technical equipment for generating data comprising at least time stamp of a video stream and signalling the generated data by means of a light from a light source.
