Selection of an edge node in a fixed access communication network

A method and apparatus for selecting an edge node from a plurality of edge nodes in a fixed access communications network. A selection node receives from a host entity a request for a network service. The selection node then obtains, from at least one further network node, data relating to a plurality of edge nodes. On thebasis of the retrieved data, the selection node selects an edge node from the plurality of edge nodes, wherein the selected edge node provides a path between the host entity and the requested network service. The selection node then sends a response to the host entity, the response including information identifying the selected edge node.

Generation of spatial downmixes from parametric representations of multi channel signals

A headphone down mix signal (314) can be efficiently derived from a parametric down mix of a multi-channel signal (312), when modified HRTFs (310) (head related transfer functions) are derived from HRTFs (308) of a multi-channel signal using a level parameter (306) having information on a level relation between two channels of the multi-channel signals such that a modified HRTF (310) is stronger influenced by the HRTF (308) of a channel having a higher level than by the HRTF (308) of a channel having a lower level. Modified HRTFs (310) are derived within the decoding process taking into account the relative strength of the channels associated to the HRTFs (308). The HRTFs (308) are thus modified such that a down mix signal (314) of a parametric representation of a multi-channel signal can directly be used to synthesize the headphone down mix signal (314) without the need of an intermediate full parametric multi-channel reconstruction of the parametric down mix.
