<p>Various embodiments of the invention provide scalable and distributed input signal coding activity detection and coding thereof (e.g. VAD/DTX) processing framework. An apparatus comprising an encoder is shown. The apparatus can be a terminal, for example a mobile phone, computer or the like. The apparatus may act as transmitter etc. The apparatus is coupled with a network element (alternatively referred to as an intermediate element or the like). The network element is coupled with apparatuses. The apparatuses can also be terminal devices such as mobile phone, computer or the like. The apparatuses may act as receivers etc. The apparatus comprises a detector configured to detect whether an input signal is active input signal or non-active input signal. There are various different detectors such as the VAD or SAD referred to above. The apparatus comprises also an encoder configured to encode a background noise component of the input signal and a signal component of said active input signal as at least two separate protocol layers during a period of said active input signal. Furthermore the apparatuses may contain the encoder and the detector as well. Also the network element may in some cases have the detector and the encoder. The network element comprises a detector configured to detect a network or network terminal receiver characteristics. The network element comprises an encoder configured to forward said input signal on a basis of said network or network terminal receiver characteristics so that depending on the network or network terminal receiver characteristics said in-put signal is encoded to meet the network or network terminal receiver characteristics.</p> |
