(EN) METHOD, SYSTEM AND APPARATUSES FOR TRANSFERRING AUDIO AND/OR VIDEO SIGNALS BETWEEN SYNCHRONOUS AND ASYNCHRONOUS NETWORKS AND FOR MINIMIZING DELAY TIME IN SUCH NETWORKS

Abrégé
(EN) The present invention refers to a method and/or system for transferring/receiving audio and/or video signals fulfilling the requirement to bridge synchronous and asynchronous networks and minimizing delay time over such networks characterised by the steps of: analysing the active network interface or verifies which network interface is receiving and/or sending data; taking a synchronous-clock signal (multiplexed signal) from the network and providing it to a bitstream analyser (3); analysing the format of the multiplexed signal obtained from another audio codec (e.g. Inverse Multiplexing); analysing the audio format (e.g. MPEG 1 Layer 3 128 kBit/s stereo); adapting the encoded signal to the IP (Internet Protocol) datagrams as required by the network interface and by the network itself in terms of protocols, packet size, etc. and resulting in a datagram signal; taking the datagram signal and putting it in the IP (Internet Protocol) network (e.g. 100 Mbit/s Ethernet).
(FR) La présente invention concerne un procédé et/ou un système servant à émettre/recevoir des signaux audio et/ou vidéo satisfaisant les exigences pour mettre en parallèle des réseaux synchrones et asynchrones et à réduire au minimum le temps d'attente dans ces réseaux. Ce procédé consiste à analyser l'interface réseau active ou à vérifier quelle interface réseau reçoit et/ou émet des données ; à prendre un signal d'horloge synchrone (signal multiplexé) du réseau et à le fournir à un analyseur de trains de bits (3) ; à analyser le format du signal multiplexé obtenu à partir d'un autre codec audio (multiplexage inverse, par exemple) ; à analyser le format audio (MPEG 1 de couche 3 128 kBit/s stéréo) ; à adapter l'horloge du réseau ISDN à l'horloge du réseau IP (protocole Internet) pour obtenir un signal numérique adapté à l'horloge ; à coder ledit signal numérique ; à adapter le signal codé aux datagrammes IP (protocole Internet) en fonction de l'interface réseau utilisée et du réseau en soi en termes de protocoles, de la taille des paquets, etc. pour obtenir un signal de datagrammes ; à prendre le signal de datagrammes et à l'introduire dans le réseau IP (protocole Internet) (Ethernet 100 Mbit/s, par exemple).
