Abstract:
1. A method comprising: receiving a signal; dividing the signal into data elements arranged in a first data stream comprising active and inactive data elements; analysing at least one characteristic of the signal to determine if the signal is stable over a plurality of data elements; classifying the active data elements as containing one of a stable voiced sound, a stable unvoiced sound, or an unstable transient sound; selecting at least one active data element to be dropped from the plurality of data elements of the first data stream if it is determined that the signal is stable over the plurality of data elements, the at least one active data element to be dropped selected from active data elements that are classified as containing either the stable voiced sound or the stable unvoiced sound but excluding active data elements that are classified as containing the unstable transient sound; dropping the selected at least one active data element; inputting frames of the data elements that are not dropped from the first data stream into packets of a core stream; and transmitting the core stream from a first node to a second node via a communication network.
