ABSTRACT:
A method and apparatus for transferring/receiving audio and/or video signals for bridging synchronous and asynchronous networks and minimizing delay time over such networks including analysing the active network interface for determining the network interface that is receiving and/or sending data, taking a multiplexed synchronous-clock signal from the network and providing it to a bitstream analyser, analysing the format of a multiplexed signal obtained from another audio codec, analysing the audio format, adapting the ISDN network clock to the IP network clock for forming a clock-adapted digital signal, encoding the digital signal, adapting the encoded signal to IP datagrams, and, inserting the datagram signal in the IP network.
