“…In our comparative study, we have also included solutions for communications for 1:n and n:m communication and added new inter-stream synchronization solutions (previous (not considered in [22]) and later ones), such as those presented in [8,[24][25][26][27][28][29]30,31] (some of them developed by the authors of this paper) [2,3,5,9,[10][11][12][13][14][15]19,; and new versions of algorithms included in the original comparative survey, such as the ones in [5,38,69,[70][71][72][73][74][75]. For example, in [69,72], the synchronization maestro scheme (SMS) for group synchronization, employed together with the virtual time rendering (VTR) media synchronization algorithm [76] has been enhanced so that the SMS scheme can be used efficiently in a P2P-based system and in a networked realtime game with collaborative work, respectively.…”
