A method and apparatus is disclosed for automatic segregation of signals of different origin, using models that statistically characterize a wave signal, more particularly including feature vectors consisting of a plurality of parameters extracted from a data stream of a known type for use in identifying data types by comparison, which can be Hidden Markov Model based methods, thereby enabling automatic data type identification and routing of received data streams to the appropriate destination device, thereby further enabling a user to transmit different data types over the same communication channel without changing communication settings.
