description Methods, systems, and computer programs for measuring quality of multimedia delivery to a client are presented. A method includes operations for embedding video markers in a video stream of a multimedia stream, and embedding audio markers in an audio stream of the multimedia stream. The video stream and the audio stream are then transmitted separately to the client. Further, video markers received at the client are extracted from the transmitted video stream, and audio markers received at the client are extracted from the transmitted audio stream. A measure of the audio-video synchronization quality is obtained by determining a quantifiable time difference between the video stream and the audio stream received at the client, where the quantifiable time difference is calculated based on the extracted video markers and the extracted audio markers.
