Abstract:
1. Method of transmitting time information in a data communication system comprising a sending part with a source and a sender and a receiving part with a receiver and a decoder, the time information being transmitted from the source, the time information relating to a clock of the source, the time information being intended for the reconstruction of images by the decoder, the time information being transmitted in a data burst framed link, wherein it comprises the steps of: sending a binary control signal from the sender to the source a fixed latency indication, which informs the source of a moment at which it is possible to send the time information with a fixed latency, and sending from the source to the decoder the time information following reception of the fixed latency indication so that the decoder slaves its own clock to the clock of the source; wherein the fixed latency is a time delay between reading and writing of a memory.
