Perceptually continuous mixing in a teleconference

摘要

In an audio teleconference mixing system, of the type mixing a first plurality of audio uplink input streams containing audio information including sensed audio and associated control information, to produce at least one audio downlink output stream for downlinking to at least one conference participants, wherein the audio uplink input streams potentially can include continuous transmission (CTX) and discontinuous transmission streams (DTX), a method of mixing multiple current audio uplink streams together to produce the at least one audio output stream, the method including the steps of: (a) determining a verbosity measure indicative of the likely importance of each current audio uplink streams; (b) where at least one current audio uplink stream can comprise a CTX stream, utilizing at least one CTX stream in the mix to produce at least one current downlink output stream.
