1. A method to receive a media stream over a distribution network from a central node connected to a plurality of devices, the method comprising:
receiving, by a device of the plurality of devices, first packets of a first type of the media stream, wherein the media stream further comprises second packets of a second type;
determining respective first playout times for the first packets, wherein the respective first playout times are based on a mean intermediate arrival time for the first packets and a time reference Tref;
receiving timestamps for the first packets corresponding to the respective first playout times;
receiving timestamps for the second packets corresponding to respective second playout times based on a predetermined ratio between a first number of the first packets and a second number of the second packets; and
causing the media stream to be rendered.
