Title : Real-Time Transport Protocol (RTP) Timestamps for Layered Encodings
Author(s) : J. Lennox, et al.
Filename : draft-lennox-avt-rtp-layered-encoding-timestamps-00.txt

The Real-Time Transport Protocol (RTP) specification defines how
layered encodings can be sent over a layered transmission system. A
source can stripe the progressive layers of a hierarchically
represented signal across multiple RTP sessions, each carried on, for
example, its own multicast group. These layered encodings are given
special treatment in RTP, notably in that the same synchronization
source (SSRC) identifier space is used across the sessions of all
layers.
The RTP protocol specification does not, however, explicitly state
how RTP timestamps are to be used with layered encodings. This
document updates the RTP specification to require that RTP timestamps
for layered encodings be synchronized, i.e. that every layer chooses
the same random initial value for the timestamp.
