FREMGANGSMÅDE TIL TRANSMISSION/MODTAGELSE I REALTID AF DATA I PAKKER MELLEM EN SERVER OG EN KLIENTTERMINAL, TILSVARENDE SERVER OG TERMINAL

摘要

A method of real-time transmission/reception of data in packets in an IP network between a server (S) and a client terminal (CT). On the server side (S), each packet (P_k) to be transmitted is assigned (A) a send continuity index (C_k) and each packet (P_k) is transmitted (B) successively together with its continuity index (C_k) to the client terminal (CT). On the client terminal side, any break in continuity of packet streams received is detected (D) on the basis of the continuity indices (C_k) associated with each of the packets received. On detecting a stream discontinuity (C_kr), at least one resend request (RR (C_kr, @CT) requesting the resending of at least one missing packet is transmitted (E) to the server (S), for as long as this or these missing packets has or have not been received by the client terminal (CT). Application to the transmission of isochronous data streams, multimedia data streams in an IP network.
