  • Methods and arrangements for adaptive thresholds in codec selection
    Patent number: 7860509
    Abstract: A method and arrangement for dynamically adapting thresholds used for selecting a codec mode to be used is presented. Thresholds are adapted in response to the current received signal quality. An estimate of actual prevailing received signal quality is obtained on which the adaptation is based. The present invention can be applied either on the mobile terminal side or on the network side, working on the uplink and/or the downlink. The thresholds can be modified on the receiving side, or, when operating in the network and working on the downlink, the threshold adaptation can be initiated in the terminal.

  • Multi-channel signal encoding and decoding
    Patent number: 7283957
    Abstract: A multi-channel linear predictive analysis-by-synthesis signal encoding method detects (S26, S27) inter-channel correlation and select one of several possible encoding modes (S24, S29, S30) based on the detected correlation.

  • Multi-channel signal encoding and decoding
    Patent number: 7263480
    Abstract: A multi-channel linear predictive analysis-by-synthesis signal encoding method determines (S1) a leading channel and encodes the leading channel as an embedded bitstream. Thereafter trailing channels are encoded as a discardable bitstream exploiting cross-correlation to the leading channel.
