RTP Clock Source Signalling
RFC 7273, “RTP Clock Source Signalling”, is a Proposed Standard document published in June 2014 by A. Williams, K. Gross, R. van Brandenburg, H. Stokking. The canonical text is published by the RFC Editor.
Abstract
NTP format timestamps are used by several RTP protocols for synchronisation and statistical measurements. This memo specifies Session Description Protocol (SDP) signalling that identifies timestamp reference clock sources and SDP signalling that identifies the media clock sources in a multimedia session.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
