RTP/RTCP Extension for RTP Splicing Notification
Jiaqi Xia, R. Even, Rongjin Huang, L. Deng · 2017
Content splicing is a process that replaces the content of a main multimedia stream with other multimedia content and that delivers the substitutive multimedia content to the receivers for a period of time. The splicer is designed to handle RTP splicing and needs to know when to start and end the splicing. This memo defines two RTP/RTCP extensions to indicate the splicing-related information to the splicer: an RTP header extension that conveys the information in band and an RTP Control Protocol (RTCP) packet that conveys the information out of band.
