The SMPTE 2110 suite of documents defines an extensible system of RTP-based essence streams referenced to a common reference clock, in a manner which specifies their timing relationships. This informative "roadmap" describes the documents in the SMPTE 2110 suite. - The diagram of Figure 1 illustrates a simplified 'essence mapping data flow' roadmap for the RTP-based essence streams as defined by the document suite.
