<p>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, if available in analog form, audio and/or video input signal in digital form by means of an A/D converter; processing the digital audio and/or video signal in order to manipulate, control, adapt or change it; converting the sampling rate of the digital audio and/or video signal for adapting the digital input clock to the network clock or for adapting the A/D clock to the network clock resulting in an clock-adapted digital signal; encoding the clock-adapted digital signal for reducing the number of bits resulting in a lower bit rate encoded signal; multiplexing the encoded signal and packing it into a resulting multiplexed signal which needs to comply with the used and/or applied network interface; putting the multiplexed signal in a network; analysing the active network interface or verifies which network interface is receiving and/or sending data; on the reception side: analysing the active network interface or verifying which network interface is receiving and/or sending data; taking the multiplexed signal from the network and providing it to a bitstream analyser (13); analysing the multiplexed signal in order to de-multiplex the signal for obtaining an encoded signal; decoding the encoded signal into a digital audio and/or video signal; converting the sampling rate of the digital audio and/or video signal for adapting the network clock to the digital output clock or to adapt the network clock to the D/A converter clock and resulting in a clock-adapted digital signal; processing the clock-adapted digital signal to manipulate, control, adapt or change it; converting in analog form the digital audio and/or video signal by means of an D/A converter; characterised in that, for reducing the delay time of the digital audio and/or video signal transfer, the IP packets generated by bitstream generating means (8) are optimised by minimizing the packet sizeand low delay coding algorithm are chosen by encoding means (6).. <IMAGE></p> |
