The RTCRtcpParameters dictionary provides parameters of an RTCP connection. It's used as the value of the rtcp property of the parameters of an RTCRtpSender or RTCRtpReceiver.

Instance properties


The Canonical Name (CNAME) being used by RTCP. This is used, for example, in SDES (SDP security descriptions) messages, described in RFC 4568. This property cannot be changed once initialized.


A Boolean value indicating whether or not reduced size RTCP is configured. If this value is true, reduced size RTCP (described in RFC 5506) is in effect. If false, compound RTCP is in use, as found in RFC 3550. This property cannot be changed once initialized.


This example obtains the canonical name (CNAME) being used for RTCP on an RTCRtpSender or RTCRtpReceiver.

function getRtpCNAME(rtpObject) {
  let parameters = rtpObject.getParameters();

  return parameters.rtcp.cname;
