The task of Bachelor's thesis has been to develop synchronizing mechanism for signaling servers, called Feedback Targets, in hierarchical structure of the feedback tree. Then verify the function of this designed synchronizing mechanism in simulation developed in Java. Using this synchronizing mechanism to shorten the time needed to travel the signaling packets trough the feedback tree and using this to obtain better reaction to possible network junction or significant packet loss while distributing multimedia data while using IPTV. In theoretic part of the thesis there are described basic protocols like RTCP, RTP and TTP. Then are described methods for packet sending in network (multicast, unicast and broadcast). The basic piece of knowledge about IPTV, its distribution and differences between IPTV and classic internet media streaming are described. Also basic terms like Feedback Target, Feedback Target Manager and FTI, FTS and FTD packets are described as well
