    摘要： 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 ISDN network clock to the IP (Internet Protocol) network clock and resulting in a clock-adapted digital signal; encoding said digital signal; 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).

    摘要： The present invention refers to a method and/or a system for transferring/ receiving audio and/or video signals and minimizing delay time over Internet networks comprising the steps of, on the transmitting side: converting, the input signal in digital form by means of an A/D converter; processing the signal in order to manipulate, control, adapt or change it; converting the sampling rate of the signal encoding the clock-adapted digital signal for multiplexing the encoded signal and packing it into a resulting multiplexed signal putting the multiplexed signal in a network; and analysing the active network interface as well as the opposite steps on the reception side whereby for reducing the delay time of the digital audio and/or video signal transfer, the IP packets generated are optimised by minimizing the packet size and low delay coding algorithm are chosen for encoding.
