TTL scopes, however, have fallen into disfavor, and current practice recommends use of administratively
scoped addresses for containment of multicast traffic flows.
4.2.14. Automatic Unicast
This Channel Type enables automatic transfer of a Presentation Recorder's SDP file to a streaming server
(e.g. a QTSS/DSS server). The transfer is accomplished by RTSP ANNOUNCE commands sent from a
Presentation Recorder RTSP client to the server. The system makes sure that the latest version of the SDP
file is always on the server (SDP files describe the media being streamed and other details such as port
assignments).
Typically the SDP file is transferred when a session starts and during the session when the SDP file
changes. The Presentation Recorder issues "Announced kill" when a session has ended.
