Abstract
Sample packets (S -Sn) are formed from an input signal ( ), there being a sample period (P -Pn) related to each sample packet. The sample packets are inserted into a packet network ( ) and transmitted to a recipient. The information content of the input signal per time unit (BR) is monitored and the information content of each sample packet (S -Sn) is kept substantially constant on the basis of this information by controlling the duration of the sample period (P -Pn) of the sample packets. Information on the duration of the sample period (P -Pn) is transmitted to the recipient in the packet network packet. The packets ( ) are received in the receiver and sample packets (S -Sn) are separated from them and supplied to a decoder ( ). Information on the duration of the sample period (P -Pn) is also separated and supplied to the decoder ( ), which uses it as the playing time of the restored output signal ( ).
