1. 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.
