3.1.4 Higher-Layer Triggered Events

  • Article

This protocol has one RTP-related higher-layer triggered event, in addition to those specified in [RFC3550] and [RFC3551].

If the audio mixer has enough mixed audio data to send an RTP packet, packets are sent as specified in [RFC3550] section 5.1, except that if the dominant speaker extension is being used, it MUST run the dominant speaker detection algorithm, either standalone or as part of the audio mixing. It MUST then move the dominant speaker to the first position of the CSRC list, or add it in the first position if the dominant speaker's CSRC is not in the list.
