    Abstract: A method of encoding multi-channel audio signals comprises generating of a first output signal (x' mono ), being encoding (38) parameters representing a main signal (x mono ). The main signal (x mono ) is a first linear combination (34) of signals (16A,16B) of at least a first and a second channel. The method further comprises generating (30) of a second output signal (p side ), being encoding parameters representing a side signal (x side ). The side signal (x side ) is a second linear combination (36) of signals (16A,16B) of at least the first and the second channel within an encoding frame. The method is characterised in that the generating of the second output signal further comprises scaling of the side signal (x side ) to an energy contour of the main signal (x mono ). A method of decoding is also presented as well as an encoder, a decoder and audio system, all according to the same basic idea.

    Abstract: A method of controlling a network entity of a data unit communication network is described. The network entity is involved in providing respective transport services to a plurality of terminals of the data unit communication network, each transport service being characterized by a set of values associated with respective service quality parameters. The method comprises: - monitoring (S60) for a presence of a collective feedback condition, and - if the presence of said collective feedback condition is determined, setting (S62) a congestion indication marking in data units of a defined group of said transport services.

    Abstract: The invention relates to a method for controlling a bit-rate of a session in a packet-switched communications system where multiple sessions are set-up via a shared resource. A current bit-rate of the session is compared to a bit-rate range valid for the session to determine a distance from the position of the current bit-rate to one of the end-points of the bit-rate range. The current bit-rate is then adapted differently depending on the distance to the selected end-point. By controlling the bit-rate of each session that is set-up via the shared resource for applications that provide delay-sensitive services to users in this way the method and corresponding system and sender- receiver arrangements have the effect that rate adaptations can be distributed among the applications so that users share responsibility for rate adaptations.
