Abstract
The invention relates to a method and an arrangement for encoding of signals in teleconferencing. The method involves receiving (502) signals from a plurality of nodes participating in a teleconference and analyzing (504) said signals. The method further involves appointing (506) one of the received signals as being a dominant signal and adapting (508) an encoder based on information related to the dominant signal. At least two of the received signals are mixed and then encoded (512), using the adapted encoder. The encoded mixed signal is then provided (514) to at least one of the nodes participating in the teleconference.

31. A method for encoding signals in teleconferencing, comprising:
-
receiving signals from a plurality of nodes participating in a teleconference; analyzing the received signals; appointing one of the received signals as a dominant signal; forming an adapted encoder by adapting an encoder based on information related to the dominant signal; forming a mixed signal by mixing at least two of the received signals; forming an encoded mixed signal by encoding the mixed signal using the adapted encoder; and providing the encoded mixed signal to at least one of the nodes participating in the teleconference. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
