Introduction This document specifies the payload format for packetization of KLV (Key-Length-Value) Encoded Data, as defined by the Society of Motion Picture and Television Engineers (SMPTE) in [SMPTE-ST336], into the Real-time Transport Protocol (RTP) [RFC3550]. The payload format is defined in such a way that arbitrary KLV data can be carried. No restrictions are placed on which KLV data keys can be used. A brief description of SMPTE ST 336, "Data Encoding Protocol Using Key-Length-Value", is given. The payload format itself, including use of the RTP header fields, is specified in Section 4. The media type and IANA considerations are also described. This document concludes with security considerations relevant to this payload format.
